Product Overview
Q195, Q235B and Q355B are the most classic and widely used GB standard carbon steel strip series, covering low-carbon forming grade, general structural grade and high-strength structural grade. This series steel strip is processed by precision slitting from qualified hot rolled and cold rolled mother coils, with uniform thickness, flat surface and stable internal stress.
Q195 features ultra-low carbon and super ductility, suitable for strapping, pipe wrapping and simple stamping forming; Q235B is universal structural steel with balanced strength and plasticity, applied for most civil construction and general mechanical parts; Q355B is high-strength low-alloy grade, replacing traditional Q345B, suitable for heavy-load bearing structures and engineering equipment.
All grades support international equivalent grade replacement, matching ASTM, EN and JIS standards. We provide custom slitting, edge trimming, deburring, flattening and fixed-length cutting services. Strict quality inspection and complete MTC documents ensure stable supply for global construction, pipe making, machinery manufacturing and hardware processing projects.
