ASTM A615 Grade 40 Grade 60 Deformed Steel Bar for Building Construction

1．Product Overview

Deformed steel bar, also known as steel rebar, is widely used in reinforced concrete structures for buildings, bridges, industrial foundations, and infrastructure projects.

The ribbed surface design improves bonding strength between concrete and steel reinforcement, helping structures withstand tensile stress and external loads more effectively. The product is available in ASTM, GB, BS, and JIS standard grades for different regional construction requirements.

2．Technical Solution

The deformed surface pattern includes longitudinal ribs and evenly distributed transverse ribs to increase mechanical bonding performance with concrete.

ASTM A615 Grade 40 and Grade 60 rebars are commonly used in reinforced concrete structures requiring reliable yield strength and construction stability. HRB400, HRB500, and BS4449 grades are suitable for international construction and infrastructure projects.
