Our steel angle bars are produced under strict quality control: high-quality raw materials are pre-inspected and then heated and rolled at 1200-1300°C into equal/unequal L-shaped profiles. After controlled cooling and straightening, the products are cut into standard 6/9/12-meter lengths. The surface is cleaned and treated with anti-corrosion coatings. Each batch undergoes comprehensive chemical, mechanical, and dimensional inspections to meet relevant standards. Finally, secure strapping/pallet packaging ensures safe global transport.

| Black Steel | Standard hot rolled surface for general structural use |
| Shot Blasting | Removes mill scale for coating preparation |
| Painted Finish | Provides additional corrosion protection |
| Hot-Dip Galvanized | Long-term corrosion resistance for outdoor applications |
| Epoxy Coating | Suitable for harsh industrial environments |
