The Australian style rolling shutter door forming machine is a high-precision cold bending equipment designed specifically for the production of Australian style interlocking rolling shutter door curtains. It can roll galvanized coils, color coated coils, and cold-rolled coils into curtains with arc-shaped interlocking structures at once. The finished product has the characteristics of tight bite, silent lifting, wind resistance, anti-theft, and smooth surface. It is widely used in the mass production of rolling shutter doors in shops, garages, warehouses, factories, and high-end residential areas. It is the mainstream automated production equipment in the rolling shutter door industry.
