ASTM A500 GRB - GRC Square - Rectangular Steel Pipe
High-Strength Structural Tubing for Modern Construction
Key Features
Dual Grades Available
GRB- Good balance of strength & formability for general structures
GRC- Higher strength for heavy loads, seismic zones, and long spans
ASTM A500 Compliance
Strict control over tolerances, straightness, twist, and surface quality.
Cold-Formed & High-Frequency Welded
Precision dimensions, sharp corners, excellent weldability and machinability ..
Typical Applications
