Angle Steel Manufacturing: From Billet to Bundled Bar
Equal angle steel from Sino East is rolled on the section mill from continuously cast billets, then passed through straightening and cooling beds before being cut to length. The result is an angle with a consistent leg, a square corner radius, and a straightness that simplifies fit-up in the fabrication shop.
We produce equal angles from 20 x 20 mm to 200 x 200 mm in Q235, Q345 and ASTM A36, in black or hot-dip galvanized finish. For structural fabrication across the GCC - portal frames, cable trays, transmission towers and tank support rings - the mill can hold one size and grade for a whole project, keeping the documentation consistent.
Lengths, Bundling and Documentation
- Standard lengths - 6 m and 12 m; custom lengths from 4 m to 12 m on request
- Galvanizing - hot-dip galvanized angles to ISO 1461 for outdoor and coastal service
- Bundling - strapped bundles with waterproof wrapping, weight marked per bundle
- MTC - mill test certificate per EN 10204 3.1 with heat number and mechanical properties
Unequal angles, channels and flat bars are produced on the same mill, so mixed structural packages can ship in one container with one documentation set.
