A36 Q235B Hot Rolled Steel U Channel | 5# 8# and Galvanized Purlin Frame Requirements
Hot-rolled U-channel steel has actual 5#, 8# and customized dimension choices. The body gives 6, 9 or 12m lengths or customization, with 2–16mm thickness and black or galvanized surface alternatives.
Select grade and section dimensions using the relevant drawing and standard. The number labels alone do not define every flange, web or thickness dimension. Galvanizing and the requested A36 or Q235B material require selected documentation.
For purlins or building frames, provide connection and structural acceptance requirements. No section capacity, selected yield test or validated load result is supplied. Request chemistry and dimensional inspection records; broad material alternatives and standard names do not establish grade equivalence or guarantee the proposed frame performance.
