This stage is the cornerstone of light steel villa manufacturing. We rigorously select and procure high-quality galvanized or galvalume/alu-zinc steThis is the core stage of light gauge steel (LGS) frame manufacturing. Using advanced intelligent Light Gauge Steel (LGS) roll forming machines, the prepared steel strips are precisely processed into keel components of various cross-sectional shapes as designed, such as C-sections, U-sections, Z-sections, and L-sections. The process typically includes automatic feeding, leveling, precision punching (for bolt connections, service holes for utilities, rivet holes, etc.), cold roll forming, and cut-to-length operations. All processing data is generated by professional structural design software and directly imported into the equipment via CNC systems, ensuring processing accuracy.el coils that meet international standards. All incoming raw materials undergo strict quality inspections, including checks for material yield strength, coating thickness, zinc/alu-zinc content, and dimensional accuracy, ensuring only qualified raw materials proceed to the next production phase. Qualified steel coils are properly stored in designated warehouse areas, with moisture-proof and rust-proof measures implemented, and are managed by batch for traceability.
