Product Description

Product Overview

Cold Drawn Square Steel Bar is a cold-finished solid square steel profile produced by cold drawing process. It features high dimensional accuracy, tight tolerance, smooth bright surface and excellent straightness. Compared with hot rolled square steel, it requires less machining allowance and is the preferred raw material for precision mechanical processing.

Core Advantages

Bright oxide-free surface, no need for secondary polishing
Precise tolerance (h9/h11), low machining allowance, cost-effective
Uniform hardness and stable mechanical properties for high-speed CNC machining
Excellent straightness and flatness, fewer defective products
Support custom sizes, fixed-length cutting and OEM processing
