Corrugated board is a composite board with galvanized steel sheet (such as DX51D+Z, SGCC, etc.) as the base material, which is rolled and cold-bent into a wave shape and coated with a color coating. Its base plate adopts hot-dip galvanizing or hot-dip aluminum-zinc process (the weight of the zinc layer is usually 180-275g/㎡), and the surface is coated with polyester, silicon-modified polyester or PVDF and other organic coatings. It has both the corrosion resistance of the zinc layer and the weather resistance of the coating, and its service life is extended by more than 50% compared with ordinary galvanized sheet.

Galvanized coils are products made of low-carbon steel, high-quality high-carbon steel, etc., through hot-dip galvanizing or electro-galvanizing processes. Hot-dip galvanized coils are made by immersing thin steel plates in molten zinc liquid to form an alloy layer and a pure zinc layer with the steel plate matrix. The zinc layer is thick and has strong adhesion and good corrosion resistance; electro-galvanized coils are made by electrochemically depositing a zinc layer on the surface of the steel plate, and the zinc layer is uniform and fine.

Aluminum coil is a rolled aluminum alloy strip made of electrolytic aluminum liquid or remelted aluminum ingot through continuous casting or hot rolling, with a thickness of 0.1-6.0 mm and a width of 20-2500 mm. It is light, corrosion-resistant, and has excellent thermal and electrical conductivity. The surface can be oxidized, color-coated, embossed, and coated. The strength grade is 1xxx-8xxx series, and GB/T 3880 and ASTM B209 are implemented. It is widely used in packaging (can lids, medicine foil), home appliance panels, architectural decoration, automotive heat exchangers, photovoltaic backplanes, and electronic substrates to achieve weight reduction, energy saving, and recycling.
