As a premier manufacturer of residential steel roof trusses, Liyou Steel provides high-strength, precision-engineered truss systems that outperform traditional wood framing. Our cold-formed steel (CFS) trusses deliver superior span capabilities, straightness, and longevity for modern homes.
✔ Unmatched Structural Performance
Clear spans up to 60 feet without interior supports
2-3x stronger than dimensional lumber
Consistent quality – no warping or shrinking
✔ Superior Material Advantages
Galvanized steel (G550) – rust and termite resistant
30% lighter than wood – reduces foundation loads
Non-combustible (Class A fire rating)
✔ Construction Benefits
50% faster installation vs. stick framing
Pre-engineered components for perfect fit
Compatible with all roofing materials
