Weights are nominal. Purlins are rolled from GI coil whose actual gauge often runs under the nominal, so delivered weight varies roughly ±10–15% by brand. Sizes and the 6.0m length are standard; exact weight is confirmed on your quote.
Grades
- Galvanized steel coil; thickness 1.0–2.0mm typical (0.8–2.0mm range).

Common questions
What are C-purlins used for?
Roof purlins and wall girts on steel-frame buildings — light, cold-formed and galvanized.
Are the listed weights exact?
No — nominal only. Actual coil gauge varies by brand (a “1.2mm” can run 1.0–1.1mm), so weight varies around ±10–15%. We confirm exact weight per brand on the quote.
C-purlin or channel bar for my roof?
Roof framing normally uses C-purlins. Channel bar is the heavier hot-rolled section for structural framing — see the channel bar page.
