Produced by heating steel billets and rolling them through specialized flat-shaped dies, it offers easy cutting, weldability, and stable load-bearing properties. Widely used in construction steel structure supports, mechanical manufacturing components, welded pipe raw materials, and bridge guardrails, it stands as one of the fundamental structural steels commonly employed in industrial and infrastructure applications.
Flat Bar Production Line
The flat bar production line uses steel billets as raw material, with the core process being the rolling of flat rectangular cross-sections. The workflow is streamlined and efficient:
Billet Heating: Billets are fed into a heating furnace and raised to 1100-1250°C to achieve optimal plasticity.
Rolling and forming: The heated billet undergoes initial rolling in the roughing mill before entering the finishing mill equipped with specialized flat-shaped rolls. Multiple rolling passes control width (12-300mm) and thickness (4-60mm);
Post-Processing: After rolling, the material undergoes cooling and straightening to ensure flatness and precision. It is cut to length as required, with high-precision products undergoing additional cold rolling;
Quality Inspection of Finished Products: Dimensions and mechanical properties are tested. Upon passing inspection, the material becomes a finished product suitable for applications such as construction supports and mechanical components.

About Packing Details
1.Bundling: Flat bar of the same specification is bundled into tight, neat units. Multiple high-tensile steel straps are used to secure the bundle, preventing it from coming apart during loading, unloading, and transit. Spacers can be placed where the straps contact the steel to prevent surface scratching.
2.Moisture and Rust Prevention: For steel with anti-rust requirements, an anti-rust oil can be applied to the surface. The entire steel bundle is then wrapped in waterproof kraft paper or plastic woven fabric to protect it from humid air and rain.
3.Palletizing or Blocking: The strapped steel bundles are placed on wooden skids or sturdy wooden pallets. This keeps the steel off the ground, preventing moisture damage, and facilitates forklift handling.
4.Marking and Shipping: A clear shipping mark is affixed to the outside of the package, indicating product specifications, quantity, and batch information. The packaged steel bundles are then loaded into containers or shipped as bulk cargo.
