Product Q&A

Q:What is the difference between C and Z steel purlin?

1) Section: C is C-type (opening to one side), Z is Z-type (flanges reversed); 2) Load-bearing: Z has 10-15% better vertical bending performance for large spans; C has balanced performance for walls; 3) Lapping: Z can lap directly, C needs splice plate; 4) Slope: Z suits slopes >1/10, C suits various slopes; 5) Price: Z is 5-10% higher; 6) Use: Z for roofs, C for walls.

Q:How to choose C steel purlin model?

Selection basis: 1) Span: <4m use C120-C160, 4-6m use C160-C220, >6m use C220-C300; 2) Load: Higher loads need higher height/thickness; 3) Spacing: Larger spacing needs larger model; 4) Material: Q355B is 50% stronger than Q235B; 5) Economy: Prioritize low steel consumption. We provide technical consultation.

Q:How to choose C steel purlin zinc coating?

1) Environment: Indoor dry 60-80g/m2, outdoor/humid 120-180g/m2, corrosive 200-275g/m2; 2) Design: Civil 80-120g/m2, Industrial 120-180g/m2; 3) Life: 60g/m2 (10-15y), 80g/m2 (15-20y), 120g/m2 (20-25y), 180g/m2 (25-30y), 275g/m2 (30+y). We offer 60-275g/m2 options.

Q:What are the C steel purlin installation steps?

1) Layout: Mark positions and spacing (1.0-1.5m); 2) Lifting: Crane lift, note opening direction (down for roof, inward for wall); 3) Fixing: Bolt/screw connection (2-3 bolts/end), splice plate lapping (>=200mm); 4) Correction: Adjust straightness (<=L/1000), flatness, spacing; 5) Support: Install tie rods, struts, knee braces; 6) Inspection: Check firmness and alignment. Wear harness for height safety.

Q:What are the MOQ and lead time?

Stock: 1 piece, 3-7 days; Common sizes (C160-C250, 2.0-2.5mm): same-day pickup. Special models/custom processing: 5 tonnes, 7-15 days. Services include custom length cutting, punching, bending, and matching parts.
