Custom Cut Equal And Unequal Steel Angle ASTM A36 S275JR Q235 Structural Angle Steel

Custom Cut Equal And Unequal Steel Angle ASTM A36 S275JR Q235 Structural Angle Steel

１．Product Overview

Steel angle bars are widely used in structural engineering, steel fabrication, machinery manufacturing, bridge construction, shipbuilding, and infrastructure projects. Equal and unequal angle sections provide stable structural support while maintaining efficient steel utilization.

The product is manufactured according to JIS G3101 SS400, ASTM A36, EN10025 S275JR, GB700 Q235, and Q345 standards for international construction and industrial applications.

２．Technical Solution

Hot rolled steel angle is designed for structural reinforcement and frame support applications. The L-shaped section provides excellent rigidity, welding performance, and load distribution in both horizontal and vertical structural systems.

Equal angle steel is commonly used for symmetrical structural loading, while unequal angle steel is preferred for projects requiring asymmetric support or space-saving structural design.

Different material grades are available according to required yield strength, fabrication performance, and project standards.
