Signature uses only the highest quality high strength structural steel in our manufacturing process. Your project will determine if we use HSS or Tube or a custom truss. All our structures are designed to meet the area code conditions but also the unique buildings performance requirements asked for by the customer. Combine this with the superior galvanizing protection or epoxy paint and you get a customized, yet modular building system able to withstand the harshest of industrial environments and weather conditions. At Signature, we build with your safety in mind by designing a structure to pass all local loading requirements without exception.
All structural steel is post hot-dip galvanized or epoxy primed and finished after fabrication. This method equally covers all surfaces of the steel, both inside and out, with a 6 – 8 mil layer of zinc or Temacoat BH paint. Post fabrication coating guarantees a corrosion free steel structure for a minimum of 15 years. Most competitors choose to apply a thin layer of zinc while the steel is being formed. Although this procedure is less expensive, it only provides a fraction of the protection and will ultimately cost more money to replace. Our complete coating coverage after production ensures long-term quality.
Steel Coating Process
Signature uses a post-dip galvanizing or epoxy painted process to ensure the greatest steel protection.
Post-Dip Galvanizing means that after all of our metal components are bent, laser cut, drilled or welded into their final configuration, they are hot dipped into molten galvanizing vats. Holes are pre drilled in the webbing for drainage and to allow the galvanizing to reach inside the webbing. This coats all the welds, both the interior and exterior of all the tubing with a uniform layer of corrosion protection. The industry quantifies this layer as 6mil thick.
It creates a far superior layer of protection when compared to using pre-galvanized steel tubing. When pre-galvanized steel is welded, the interior corrosion protection is damaged from the heat. This creates numerous small defects in the layer of protection inside the steel tubing. These defects corrode and eventually degrade the strength of the structure. The benefit of using the Post Hot Dip method of corrosion protection is the elimination of a potential corrosion problem, the extended life of the structure, and a better warranty. Our steel can also be re-dipped without sandblasting or fear of warping.
Our commitment to quality continues with the application of Tikkurila Coatings on our structural steel, after the metal components are fabricated into the final configuration. In this process, the metal components are fabricated, laser cut, drilled, and welded; sandblasted smooth; painted with Temacoat BH, TemaZinc, and 77 & 99 Primer; and finished with epoxy coatings of TemaCoat BH, Temacoat HB 30, Temador and Temathane. Pre-drilled Holes allow the primer and epoxy coatings to create a uniform layer of corrosion protection on the interior and exterior of the structural steel.
During the application, all surfaces are dried and sandblasted smooth in optimum ambient air conditions. Quality is ensured with compliance to ISO 8501-1 standards – a sandblast grade of Sa2½. Adhesion is further increased when optimum sandblast levels are unattainable by phosphating. Epoxy Paint is the most widely commissioned coating used to protect structural materials for bridges, skyscrapers and maritime projects.
Epoxy Paint is used on a variety of metal and concrete materials to protect and decorate. Epoxy Painted surfaces have excellent resistance to chemical, mechanical and climatic stress. They can also have special properties, such as electrical conductivity and fire retardation. Standard color choices are black, grey and tan with custom colors available upon request. The positive impact epoxy coats have on man-made environments proves Signature’s commitment to supplying high-performance, environmentally compliant products.
