Optimize your building’s roof system with LiYou’s expert steel roof truss design services. Our steel roof truss designs are engineered for maximum strength-to-weight ratios, ideal for warehouses, airports, and residential villas. Using software like PKPM and 3D3S, we create steel roof truss designs that accommodate snow loads, wind pressures, and aesthetic requirements—all while reducing material waste.
From the Philippine Logistics Warehouse (11,790㎡) to the Guangxi Health Food Plant, our steel roof truss designs have spanned 12+ countries. We use galvanized or painted steel trusses with precision-cut connectors for easy installation. Every steel roof truss design undergoes 3+ quality checks, including anti-rust treatment and load simulations.
Why LiYou?
20+ years of steel roof truss design experience (Senior Engineer Jim Xu).
Custom spans up to 60 meters without intermediate supports.

High Load-Bearing Capacity: Supports heavy roof loads, including snow, wind, and mechanical equipment.
Long Span Design: Large open interiors without the need for additional columns.
Durable Materials: High-strength steel resists corrosion, fire, and environmental wear.
Customizable Layouts: Gable, mono-pitch, curved, or multi-span trusses according to building requirements.
Prefabricated Components: Factory-made trusses enable efficient assembly and reduced labor costs.
Versatile Applications: Warehouses, industrial buildings, aircraft hangars, commercial structures, and sports facilities.
| Component | Description |
|---|---|
| Top Chord | Upper horizontal members of the truss supporting the roof |
| Bottom Chord | Lower horizontal members supporting the ceiling or floor below |
| Web Members | Diagonal and vertical components distributing loads |
| Gusset Plates | Connect and secure all truss members at joints |
| Optional Features | Purlins, roofing panels, insulation, and ventilation components |
Planning & Structural Analysis: Calculate load requirements, span, roof slope, and truss type.
Material Selection: Choose steel grade, purlin type, and protective coatings.
Fabrication: Prefabricated steel truss components produced according to design specifications.
Installation: Trusses lifted and secured, followed by purlin and roof panel attachment.
Inspection & Safety Check: Ensure all joints, bolts, and welds meet structural standards.
Warehouses & Storage Buildings: Long-span trusses provide column-free interiors.
Industrial Facilities: Support heavy machinery, cranes, or mezzanines.
Aircraft Hangars & Workshops: Wide open space for aircraft, vehicles, or equipment.
Commercial & Sports Buildings: Stadiums, gymnasiums, and exhibition halls with high load requirements.
Truss Type & Layout: Gable, mono-pitch, curved, or multi-span.
Materials & Finish: Galvanized steel, powder-coated, or painted finishes for corrosion protection and aesthetics.
Optional Features: Purlins, roofing panels, insulation, skylights, and ventilation.
