Thin Gauge Hot Rolled Steel Coil – SPHC Stamping Grade (0.6–1.2mm)
Product Overview
Thin-gauge hot rolled steel coil (HR) is a precision-rolled light-gauge steel product designed as a cost-effective alternative to cold rolled steel for stamping and forming applications. Manufactured with precise rolling technology to achieve thicknesses down to 0.6mm, this SPHC grade delivers good formability, consistent dimensional accuracy and excellent value. It is widely used in automotive components, hardware manufacturing, pipe production and general stamping, delivering comparable performance to cold rolled steel at a significantly lower cost.
Why Choose CNB Thin-Gauge Hot Rolled Steel?
CNB is one of the few suppliers capable of supplying high-quality thin-gauge hot rolled steel down to 0.6mm thickness. We use optimized rolling and cooling processes to ensure uniform thickness, flatness and mechanical properties across the full coil width. Our thin HR products undergo strict thickness tolerance control and surface quality inspection, making them a reliable substitute for cold rolled steel in many applications. We offer both black as-rolled and pickled & oiled surface options to match different processing requirements.
