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

A prefabricated steel roof truss is a factory‑fabricated, precision‑engineered structural framework designed to support roof loads in residential and commercial buildings. Compared to traditional wood roof trusses, steel trusses offer higher strength‑to‑weight ratios, consistent structural quality, and superior resistance to termite, fire, and weather effects — making them an ideal choice for modern construction.
A prefabricated steel roof truss consists of interconnected steel members arranged in a triangulated pattern that efficiently distributes loads from the roof surface down to the supporting walls or columns. These trusses are manufactured off‑site and delivered ready for assembly, reducing on‑site work and accelerating construction schedules.
Steel trusses may be made from cold‑form steel (typically G550 light gauge), hot‑rolled members, or hybrid configurations depending on span, load requirements, and architectural design.
Steel trusses outperform wood in strength and lifespan. They can span longer distances without intermediate supports, enabling open interior spaces and flexible designs.
Factory fabrication ensures every truss meets strict tolerances and engineered specifications, reducing variation and potential on‑site errors.
Prefabricated components arrive ready to install, speeding up roof framing and lowering labor costs when compared with traditional stick‑built methods.
Steel does not warp, split, or decay like wood, and it inherently resists termites and moisture‑related damage. With proper coatings (galvanization), steel trusses maintain performance in extreme weather conditions.
Prefabricated steel roof trusses are suitable for:
Single‑Family Homes & Villas — reliable roof framing with long lifespan
Garages & Accessory Buildings — robust support for secondary structures
Modern Architectural Designs — open plans, vaulted ceilings, attic spaces
Remodeling & Renovations — retrofit applications where wood might fail
Steel truss systems support a variety of roofing materials and are compatible with most residential roof designs.
| Truss Type | Best For |
|---|---|
| Fink Truss | Most residential roofs |
| Scissor Truss | Vaulted ceilings, open interiors |
| Attic Truss | Bonus space, storage above |
| Cantilever | Extended overhangs/porches |

Q: Are steel roof trusses better than wood for homes?
Steel trusses offer higher strength, fire resistance, and dimensional stability compared to wood, with fewer issues like warping or pest damage.
Q: Can steel roof trusses be customized?
Yes. They can be engineered for specific spans, roof pitches, and load conditions based on your home design.
Q: Do prefabricated steel trusses cost more than wood?
Steel trusses can have a higher initial material cost but typically reduce long‑term maintenance and labor costs, often proving more economical over the building's lifetime.
