| Item | Specification | Description |
| Material (Chord & Web Member) | Chord/Web Member: Q235B, Q355B (S235JR, S355JR) | High-quality carbon/low-alloy steel; chord (section steel/pipe) for main load-bearing, web (angle/round steel) for force
transmission. |
| Galvanizing Process | Hot-Dip Galvanizing (HDG) | Complies with ASTM A123/A123M or GB/T 13912; zinc coating ≥ 85 μm (100-120 μm for coastal/humid areas). |
| Truss Span (m) | 6-30 (customizable for special spans) | For small-to-medium spans; spans >18m need intermediate supports or section optimization. |
| Truss Height (m) | 1.2-6.0 (height-span ratio 1/5-1/8) | Determined by span, load and slope; ensures optimal performance and cost-effectiveness. |
| Roof Slope | 1:2.5 - 1:5 (20°-26.5°) | Adapts to roof materials; facilitates rain and snow drainage. |
| Panel Spacing (m) | 1.5-3.0 | Node spacing affecting truss stiffness and purlin arrangement. |
| Section Size of Members | Chord: H-beam (100×100-300×300)/Angle steel (L50×5-L100×10)/Pipe (φ50×3-φ159×6);Web: Angle steel (L40×4-L80×8)/Round steel(φ16-φ32) | Customized by load/span; larger spans use heavier sections. |
| Mechanical Performance | Yield Strength: ≥235/355 MPa (Q235B/Q355B); Tensile Strength: 375-500/470-630 MPa | Complies with GB 50017/AISC 360; stable under rated load. |
| Connection Method | Factory Welding + On-Site Bolt Connection | Factory pre-welding for precision; on-site bolting for quick assembly and reliability. |
| Applicable Load | Dead Load: 0.3-0.8 kN/㎡; Live Load: 0.5-1.0 kN/㎡; Snow Load: 0.3-1.5 kN/㎡ (regional-based) | Adjustable per local codes and scenarios (e.g., enhanced snow load for heavy snow areas). |
