Hot Rolled I Beam 10#–40# GB Standard SS400 Q235 Structural Steel

１．Product Overview

Hot rolled I beam is designed for structural engineering and industrial construction applications requiring stable load-bearing capacity and dimensional consistency.

Manufactured according to GB, JIS, and EN standards, the product supports both Chinese standard beam sections and European standard

IPE/IPEAA profiles for international construction projects.

The hot rolling process improves structural integrity, weldability, and fabrication performance for heavy-duty steel structure applications.

２．Technical Solution

The beam is produced through controlled hot rolling technology to achieve stable web thickness, flange geometry, and mechanical performance.

Q235B, SS400, ASTM A36, and S235JR steel grades provide balanced strength, ductility, and welding compatibility for industrial fabrication and structural construction.

The available section range from 10# to 40# supports applications from light steel fabrication to large-span industrial structures.
