What is the difference between Prefabricated Roof Trusses and Structural Steel Roof Trusses?
Prefabricated Sigma Truss
- High-tensile steel, fully galvanized for guaranteed rust resistance.
- Rust-free for life, with no anti-rust painting required.
- Designed with specialized engineering software for absolute precision in every part.
- All prefabricated roof components come pre-cut and numbered for easy, hassle-free on-site assembly based on the design plan
- 5 Year Installation Warranty
Structural Steel Roof
- It uses general black steel, which is not rust-resistant.
- Apply rust-preventive paint before installation and every time after welding.
- Depending on the technician's experience can lead to slight inaccuracies.
- Cutting and painting anti-rust coating on-site wastes installation time, and the quality depends too much on the workers' skill.
- No warranty.
