And we are metal art fabricator. As business environment evolves rapidly in Canada and more specifically in Ontario, we are following the trends. We are adjusting our fabrication capabilities to meet new technological challenges and evolve with the trend. We also plan to become more open to international clients including large international companies from America and Europe.

Our metal fabrication position in the middle of 2026

As of May of 2026, the aluminum fabrication has become our main priority with high demand in custom aluminum fabrication projects. The emerging stainless steel fabrication market in 316 and 318 stainless steel seems to be a relatively new development for us. As predicted in 2024, the significant decline of construction business in Ontario will affect negatively mild steel fabrication market for many years to come. Therefore we have reduced our efforts in this market to security products and some niches market. Luckily, we have never participated in fabrication projects for automotive industry including its maintenance side. Avoiding this market was one of better management decision that I have ever made.

Most importantly, our fabrication shops in London and Lucan provide one source fabrication service for custom metal fabrication projects in aluminum, mild steel and stainless steel. Furthermore, our custom metal fabrication service for precision fabrication project will suite your budget, project’s functionality and project’s utilization time. You can find more insight about innovative product weldments here. In fact, our precision fabrication projects are usually related to mechanical components, steel cast’s supports or aluminum cast’s supports.

Improvements in your fabrication designs

We also believe in our welding shop’s contribution to your fabrication project in following:

  1. overall fabrication rigidity,
  2. weld size, and joint assembly
  3. reduction of fabricated piece’s weight, or recommendation of increased thickness material
  4. maintenance of tolerances between structure’s mechanical components
  5. improvements in mechanical joints between metal fabrications containing at least two different metals and/or alloys

Not only we substantially contribute to our client’s designs of precision metal fabrication in London, but also reduce costs through practical fabrication solutions. Additionally, we reduce bureaucracy in our fabrication shops through implementation of sketches, flow of communication that includes videos, and images. The final report that includes data and images is also available to our clients. As I have mentioned above we are evolving in our fabrication effort in Lucan and in London, Ontario.

Aluminum Metal Fabrication in the middle of 2026

The aluminum metal fabrication in London market share has grown slowly in our overall business activities. I have been scrambling for solutions to economical decline in Ontario in 2023 and 2024. Then I have tapped into aluminum fabrication projects by accident really. We have been welding aluminum for years through our mobile welding activities. Therefore I knew since beginning that aluminum fabrication is not an easy task.

2 larger aluminum flag pole tops are our modified innovative product weldments. We couldn't simply cut off the top plates of the wheel assembly and then weld the new one since the temperature would damage the bearing inside the hub. May 16, 2025 Lucan Ontario JW Portable Welding & Repairs

Where is a will, the solutions will happen and we have started to fabricate from aluminum on more steady bases. I have also increased promotion of our aluminum fabrication services for maintenance, specialty construction, heavy machinery and car washing businesses. Now, we not only offer aluminum metal fabrication in London but also aluminum welding on site. This is very helpful in attaching fabricated projects or modifying aluminum projects prior attachment.

Aluminum Fabrication in 2026 and in near future

As of 2026, I see us improving rapidly in custom aluminum fabrication projects. These improvements will soon lead to devoting one large station to aluminum fabrication in London. The new station will feature custom sophisticated positioning and a new sophisticated welding machines. I realize that for a few readers this is not a challenging project. However, for the majority of owners, technicians and engineers that are in radius of 150 km from London the shop in Lucan is perfect. We can handle more sophisticated aluminum projects with relatively fast turnover is an attractive solution. Especially, that our closes competition is in Mississauga.

Stainless Steel Fabrication in 316 and 318 stainless in 2026

As mentioned above, the stainless steel fabrication in 316 and 318 stainless is our emerging market with high hopes. We have been in the market of stainless steel fabrication for years now but with lower grades stainless fabrications that have been based on fast food fabrication needs. With a significant increase in restaurant bankruptcies in 2025 in Ontario, the restaurants have faced restrictive budgetary times. Therefore, many restaurants have cancelled orders. In fact, our stainless steel fabrication business have been on the decline since 2022.

Fortunately, for us the fabrication from higher grades of stainless steel such as 316 stainless and 318 stainless have appeared. These orders come from pharmaceutical and medical industries. These stainless steel fabrications require some different techniques and different technologies.

We first have improved on gas shield distribution system for these fabrications. Then we have improved lights on the stainless steel station. With improvements of abrasives and polishing technologies we have met the standard of medical equipment. In my opinion more improvements are needed that will include better heat deflection setup and better positioning system. We possibly also need more sophisticated Tig welding machine. Nevertheless, I welcome new orders from medical and pharmaceutical businesses in 2026/2027

Mild Steel Fabrication in 2026

The construction and perhaps real estate business in Ontario is going through a painful contraction and in my opinion this contraction will deepen in the coming years. The large builders have left their contractors without income and in many cases with unpaid invoices. Now they meet together in courts. In the best case scenario these contractors can count on 65% recovery of cost committed to the project and many of them will commit bankruptcy.

What have saved us from this nightmare was a strict payment regime with 50% deposit, refusal of projects from general contractors who do not pay on time and diversification to other areas of mild steel metal fabrication in London area. Our famous Black List served us very well.

The diversification have led us into development of new niches and specialties. These other areas of mild steel fabrication include security fabrication products for upscale markets and structures based on HSTS and HSTR for specialty manufacturing market.

Security Market

In security market we excel with relatively quick turnover, attractive and esthetic designs, strength upgrades and difficult to breaking in solutions. With crime rate rising and burglars breaking in in most prestigious subdivisions in Ontario, I expect our products that feature solid mild steel in significant thicknesses will sell well. These designs include traditional or modern window grills, window bay covers, inside window bars in basements, inside nets in windows of steel doors, and variety of inside locking devices on metal doors.

The commercial market for our security mild fabrication is also improving with our upscale clients leading the way demanding even higher strength upgrades and anti breaking in solutions. Simply put the rich businesses with valuable content are spending on premium solutions instead of cheap tubing that tends to bend.

HSTS and HSTR market

The commercial market for our designs in HSTS and HSTR designs features structures such as removeable platforms for light equipment, small foldable ramps and safety barriers.

The cooperation with JW Investrade Inc and their metal grating allows us to offer small movable and foldable ramps. These ramps can handle significant loads and can be repositioned easily with the pump truck.

We specialize in variety of attachments to the existing machinery, semi-trucks and trailers that change the functionality of them. This product line features our designs that are certified by P.Eng. if it is necessary.

The main reason for demand of our products is the necessity of business adaptation to declining economic activity in Ontario. Manufacturers try to increase their product depth or offer slightly new product and they need to accomplish that in the same facilities. This prompts them for ordering removable platforms, foldable ramps and safety barriers. On other side trailer modifications are on the rise since many many owners try to improve their trailer functionalities to accommodate to their needs.

Our goals for metal fabrication in London going forward

We want to attract more foreign buyers for our custom metal fabrications in London from America and from Europe. Presently the mobile welding service occasionally handles orders from US clients that have assets in Ontario. These orders relate mostly to the maintenance aspects of the clients’ property.

We see the same pattern developing for our custom fabrications for European and American clients who own assets in Canada. Unfortunately, due to Canadian political environment exports of fabrications to American clients is on the declining slope.

We welcome in London custom fabrication projects from GTA, Toronto, Mississauga, Milton and Oakville

Keeping this in mind, we welcome metal fabrication Toronto inquiries in regard to any other industry except structural steel elements. To initiate the process, please attach the drawings of your planned metal fabrication in your email. And we will provide our quote promptly.  If you do not posses engineering drawings, but you know what you want than please provide the sketch of your idea. Here is the best way how to reach us for your major fabrication projects

Complex metal fabrication in London Ontario

Our fabrication shops in London and Lucan, Ontario, enthusiastically acquire complex metal fabrication projects that involve fabrication process consisting of joining multiple fabricated pieces into one unit. Within the whole process, we maintain precise tolerances. With our precise specialization in metal fabrication in London, Ontario, we undertake projects consisting of multiple metals and machined parts.

We accomplish the most complex fabrication projects on client’s premises for client’s engineers, technicians to be able to contribute to the project’s stages and to cut bureaucracy. In this way client’s benefit in increased control over the project, use of our engineering knowledge in problem solving and in fast project’s progress. Here is more about our on-site fabrication.

We perform custom metal fabrication’s orders from one unique fabricated piece to multiple same fabrications or weldments. As mentioned above, we do not fabricate typical elements for construction industry although we fabricate and weld on construction sites.

Our projects of metal fabrication in London, Ontario, involve rather more advanced projects with very precise tolerances. In house engineering is provided and independent P. Eng. certification is available. In fact, most of clients benefit tremendously from our in-house engineering due to significantly reduced cost and high turnover. Unfortunately, clients from the construction industry have to look for a different supplier. 

Metal fabrication in London with metal art components

Metal fabrication with art components is one area where we excel in our fabrication shop in London. Our clients demand that our fabrications with metal art components look impressive. Moreover, they must make stunning effect. The process starts with the interview to familiarize ourselves with basic objectives of the metal fabrication purpose. Then we produce drawings that help visualize to the client our concepts. During the drawings stage we consult with artists that are familiar with particular art.

Unfortunately, with declining of household discretionary spending the residential art is on significant decline. We are interested in developing a more commercial art fabrication for our commercial and industrial clients. In fact, we are present in religious art with our clean and more traditional designs such as advent wreath stand, altar folding step and display stand . We can also offer more contemporary designs in metal as we are familiar with contemporary artists in Ontario.

Steps to follow metal art fabrication

The metal fabrication of art components follows simple steps. After the drawings stage is time for a modeling stage when we must maintain certain dimensions and obligatory functionalities. The clients often have difficulty imagining proportions between elements. These clients are not sure how the whole thing will look like and how certain components will interact. The metal artwork modeling accomplished from nonmetal materials forms an important part of the whole modeling process. The metal artwork modeling gives us a perspective and dimensional coordination between metal artwork pieces and the functional components. It is paramount to us to exactly understand how the functional components interact with metal artwork. Our forger is consulted at this stage.

Small Fabrication Shop in London

Our fabrication shop in London Ontario specializes in precision metal fabrication of relatively small pieces that interact with each other. Or they interact with other fabrications or mechanical components. These fabricated pieces are interacting with each other in very tight fit tolerances. Our mechanical background and experience as industrial millwrights and European mechanical engineering background makes us a natural fit for precision fabrication.

We specialize in

  1. Custom aluminum fabrication
  2. Stainless steel fabrication
  3. Mild steel fabrication of weldments used outside of construction industry

The interactions and movement of fabrications influence how we approach the metal fabrication process in our fabrication shop. We always try to design the fabrication process in such a way to avoid any assembly issues. Furthermore, we also understand the cumulative inaccuracies effect on the assembly failure. Therefore, we sometimes recalculate the fabricated parameters to consider fixed and critical components. Fabrications within the precision metal fabrication concept are assembled in our metal fabrication shop in London, Ontario, many times prior delivery to customer.

Large Fabrication Shop in Lucan

The recently purchased shop in Lucan is located at 5558 Clandeboye Dr. and is shared with our sister company JW Investrade Inc. The Lucan shop features 3 very large and movable welding tables that can create a large leveled fabrication plane. This shop specializes in repairs of fabricated weldments in all metals including aluminum, stainless steel and fabricating new stronger structures.

We fabricate there aluminum jigs for repair of aluminum trailers, and aluminum frames. We also fabricate there large steel signs and variety of steel structures for farming industry.

The shop in Lucan often also acts also as prefab shop to produce parts for our mobile welding projects.

Free feasibility study for your small project

JW Portable Welding & Repairs provides free feasibility study for your small project that will be scheduled for fabrication in our metal fabrication shop in London and/or in Lucan. Certainly, larger scale feasibility studies involving rather larger projects are treated differently and are payable pending the degree of our involvement. However, small projects that require feasibility study regarding available options and solutions has opened a new niche for our fabrication shops.

So far, our feasibility studies referred to fabrication of structural elements and components that modify the existing equipment and machinery in order to increase their utilization time. Sometimes however we must design a structure to facilitate a functionality such as in foldable step example.

In simple terms, we first build models from inexpensive materials such as wood, heavy paper, and cardboard to visualize the challenges and provide solutions. These studies have involved not only fabrication of the new elements and components but also installation of them on site.

Since we are a full-service welding company with advanced welding technologies in mobile welding and portable welding, the installation of these components that require more advanced welds comes to us naturally. More importantly, we take care of minor and final modifications prior to the installation free of charge since we have fabricated the whole piece. The rule is simple, since we build it, we take care of it.

Strong mechanical background and years of experience in variety of industries.

Our strong mechanical background, the owner is a mechanical engineer (Poland) and certified interprovincial industrial millwright and years of experience in variety of industries have allow us to conduct feasibility studies in kitchen equipment industry, machinery maintenance industry, commercial trailer industry and water drilling industry. These fabrication projects involve one or multiple pieces of weldments that improve leveling, precise positioning, reduction of vibration and reduction of crack development in welds and in metal.

Most importantly, our feasibility study allows us to make technical sketches and drawings that lay foundation for metal fabrication in our fabrication shops in London Ontario. Our clients in return not only receive multiple options with tangible resolutions to their complex technical problems, but also save time and funds otherwise devoted to production of technical drawings.

Please keep in mind that our feasibility studies do not involve construction industry.

Fabrication starts when modeling receives your approval.

Once the modeling is done and approved then the metal fabrication and assembly of other components including forged components starts in our fabrication shop. We maintain the order of assembly during the metal fabrication process to make the final assembly as easy as possible. Please keep in mind that certain components delivery could be scheduled much in advance for easy installation on site.  

Custom metal fabrication

Custom metal fabrication lays at the base of many of our fabrication projects in our metal fabrication shops in London Ontario. Our customers can choose the metal they want us to make their fabrication. In our fabrication shops in London, we do steel fabrication, aluminum fabrication and stainless-steel fabrications. Pending the metal choice for your fabrication, we approach these projects slightly differently. The approach differences for fabrication in particular metal originate from differences of

  1. welding consumables,
  2. welding parameters,
  3. joint preparations, and
  4. warpage characteristics.

Moreover, the specific metal fabrications do not interact with each other and each project runs its course separately. However, some fabrication projects have involved steel fabrication and aluminum fabrication or steel fabrication and stainless-steel fabrication. Furthermore, our abrasives do not mix to maintain complete purity during the welding process. We use a very simple but effective method to separate consumables pending their designated metal.

Your metal fabrication project requires integrity

Your metal fabrication project requires integrity, especially if you can not recognize quality of welding processes. There are many factors influencing the quality of welding process and they depend on welding technologies used, welding procedures used, and welding consumables used. These factors influence not only utilization time of your project but also accuracy and comfort of operation. Therefore vetting process of welding companies is so important prior choosing your fabrication shop. Our fabrication shops in London and in Lucan, maintain very stringent procedures in all our fabrication projects. We are also open to modern fabrication technologies that increase our quality and efficiency.

Our metal suppliers

In the light of our metal fabrication success, I need to mention our metal suppliers with excellent service, valuable advice….and custom cuts. First of all, this fabrication shop in London Ontario buys steel from St. Thomas Steel Centre , and Hunter Steel for their superior service. Secondly, we buy our small and untraditional pieces of steel as well as aluminum pieces from Metal Supermarket in London. In fact, I would like to recommend these suppliers to buyers of steel in London area.
