PU roller shutter slat door machine is ideal for the manufacturing rolling shutter slats with variable lengths and in large quantities. The alloy aluminum and galvanized zinc steel which is used to make slats have neat external appearance, even ripples, high utilization and strength. The PU or polyurethane foam insulated rolling shutter slats have good ability of heating preservation, compared to rolling shutter door slats and roller shutter door panels which have nothing thermal materials insulated.
