In-House Component Manufacturing Capabilities
Legacy Building Solutions has clear and thorough specifications for every component in our custom building manufacturing. Every component specification meets quality standards set by Legacy and the appropriate certification agencies.
Rigid Steel Frame Fabrication
Steel framing members and small components are fabricated onsite from 55 ksi steel. The manufacturing shop maintains an inventory of steel sheets for expedited delivery, along with mill certs for traceability. Depending on the building specifications, the steel utilized is 10-gauge to 1-inch or thicker plates.
The steel I-beams are formed using submerged arc welding for a solid attachment. Flanges are individually formed and pressed together. The steel sheets are cut using a nesting system to reduce or eliminate waste and shorten manufacturing time. A Canadian Welding Bureau (CWB) and American Welding Society (AWS) Certified Welding Inspector (CWI) is on hand to verify the quality of welds to CWA W59-13 standards.
The final step of steel manufacturing is adding a finish. Painting and priming are done in-house in the same facility as the fabrication. Paint and primer are available in a variety of colors.
For corrosive environments, frames are hot dip galvanized (HDG) for an additional layer of protection. Frames that will be hot dip galvanized are sent to an offsite location for dipping in the zinc baths. The HDG process ensures that all steel is coated with an even layer of zinc so there is no place for corrosion to begin.
Fabric Panel Manufacturing
Fabric panels are manufactured in a temperature- and humidity-controlled warehouse. This ensures the strength of the fabric welds. All fabric is manufactured to ISO 9001 specifications.
PE and PVC fabric rolls are inspected for imperfections and color matching, and tested to ensure compliance with material specifications such as tear strength and elasticity. At the beginning of each shift, all machinery is inspected to ensure it is in proper working order.
Each fabric panel is carefully cut from the roll. The cutting floor is marked at regular intervals to verify the accuracy of the cuts. Then the cut panels are permanently welded using a hot air or wedge weld to form a wall or roof panel, typically 20 feet wide. Finally, a keder rope is attached at the edges of the fabric panel.
After manufacturing, the cut and welded fabric panels are then labeled with the project name and the location on the building. The completed panels are rolled up and wrapped in waste fabric for shipping to the site. The fabric is wrapped and tied with loops to prevent damage or tearing during shipping.
After all components are completed of the fabric building manufacturing process, they are shipped to the building site. Installation crews arrive on site in time to unload the building components.
