This product is a digitalized H-shaped light steel horizontal production line, primarily used for the production of H-shaped steel beams. The production line incorporates equipment such as H-shaped steel horizontal assembly, horizontal welding, chain flipping, and horizontal correction machines to achieve a production process where H-shaped steel beams are assembled once, welded twice, and corrected once. Compared to traditional vertical structures, this horizontal production line offers higher production efficiency. Additionally, the production line is equipped with advanced technologies including a PLC automatic control system and dual-arc dual-wire welding process, enabling labor reduction and increased efficiency. Through this digitalized H-shaped light steel horizontal production line, production efficiency can be improved, costs can be reduced, and product quality and consistency can be ensured.
