ASTM Q235 Hot Rolled Carbon Steel Coil 5mm 10mm 15mm Thickness for Industrial Manufacturing Applications
Zhengde hot-rolled steel coils are manufactured using slabs as raw materials, processed through rough rolling and finishing rolling units after heating. The resulting hot steel strip is cooled via laminar flow and coiled into steel strip coils, with additional finishing operations available based on customer requirements.
