Puppet Steel
1 / 5
We supply a comprehensive range of hot rolled steel products, including black mill finish coils, pickled and oiled (HRPO) sheets, and heavy gauge plates. The hot rolled steel is manufactured from continuously cast slabs, processed through roughing and finishing mills under controlled temperature and cooling rates. Our hot rolled steel covers structural carbon steel (SPHC, SS400, Q235B, S355JR), HSLA (S355MC, S420MC), weathering steel (Corten A/B, SPA-H), pressure vessel grades (A516 GR70, P265GH), and deep drawing grades (SPHE, DD13). Thickness ranges from 1.0mm to 200mm, with widths up to 2000mm. The hot rolled steel can be supplied as black coil, pickled and oiled sheet, or cut-to-length plate, with optional edge trimming and slitting. HRPO offers a scale-free smooth surface comparable to cold rolled, at a 10-20% cost reduction for many non-critical surface applications.
