Q235B Continuous Cast Steel Slab – Plate & Coil Rolling Grade
Product Overview
Q235B carbon steel slab is the standard flat feedstock for hot rolled plate and coil production. Manufactured by continuous casting into rectangular thick section, it delivers uniform chemical composition, clean internal structure and consistent hot rolling performance. This general-purpose grade is the most widely used slab material for rolling structural plates, commercial coils and wide strip products.
Why Choose CNB Steel Slabs?
We source steel slabs directly from large integrated steel mills with strict control over casting quality, internal soundness and surface condition. Every slab undergoes surface inspection and dimensional verification to ensure reliable performance in downstream hot rolling. We offer both cold and hot charging options, with custom sizes and surface conditioning to match specific rolling mill requirements.
