The welds on MegaDome® buildings are made of silicon bronze (ERCuSi-A). Many years of research and testing at our factory have shown us that this type of welding is fully compatible with the pre-galvanized steel coating and makes it much more resistant to corrosion compared to conventional welding. By utilizing silicon bronze welding instead of conventional methods, we ensure that every joint maintains the structural integrity and rust protection required for the harshest environments.
Conventional welding
The molten steel used in conventional welding burns protective treatments and contaminates the weld. Galvanization mixes with the solder, which leads to a loss of quality and strength. The result is that the welding starts to rust over time and no longer has the strength to support the structure. It is possible to protect each solder with paint, but this type of protection is limited. By utilizing bronze welding instead of conventional welding, we avoid this thermal damage entirely, ensuring the joint remains as structurally sound and corrosion-resistant as the rest of the galvanized frame. “By choosing our specialized bronze welding process over conventional welding, you are investing in a building engineered to withstand the harshest Canadian climates without the risk of structural rust.
Silicon bronze welding
ERCuSi-A weld, better known as silicon bronze weld, is the best option when it comes to welding a pre-galvanized steel structure. This type of welding doesn’t affect the coating and retains all galvanization properties. As a result, the weld and the surrounding area are resistant to corrosion and rusting.
We are the only Canadian company authorized to weld steel structures of buildings using silicon bronze. This type of welding requires advanced expertise and great attention to detail. Our in-house engineers design solid structures welded to silicon bronze. Our team of Harnois welders then works to ensure all norms and techniques are respected in order to guarantee the quality of the final welds. By combining our exclusive Canadian authorization with rigorous quality control, we provide a superior bronze welding solution that outperforms conventional welding in even the most demanding environments.
Proven solidity
Our engineering team tests every model on full-size structures. These tests are designed to determine maximum capacity and to optimize the components as needed, all while respecting Canadian codes and standards.
We have developed a unique expertise that allows us to weld pre-galvanized steel structures without affecting protective treatments. In Canada, durable silicon bronze welds are only available for MegaDome® buildings, ensuring your peace of mind for years to come.
Conclusion: The MegaDome® Advantage
In conclusion, the choice between bronze welding and conventional welding is the difference between temporary protection and a lifetime of structural integrity. While standard welding methods compromise the galvanized surface and invite premature rust, our specialized silicon bronze process preserves the zinc coating to ensure maximum corrosion resistance. As the only Canadian company authorized to utilize this advanced technique for building structures, MegaDome® offers a level of engineering excellence that is simply unmatched in the industry. By prioritizing bronze welding over conventional welding, we provide our clients with a superior, maintenance-free solution that is built to withstand the harshest environments. Invest in the durability, innovation, and expert craftsmanship that only our certified Harnois welding team can deliver for your next project. Experience the superior strength of bronze welding.
The Sustainable Choice for Your Infrastructure
Furthermore, the environmental benefits of bronze welding are significant for modern infrastructure. By eliminating the toxic zinc fumes typically released during conventional welding, we provide a safer workplace and a cleaner production cycle. This sustainable approach reduces the need for expensive chemical recoating and frequent structural repairs over time.
