CRC Incold Rapid Doors FOLD: fold-up doors

The FOLD-UP door is strong thanks to the folded frame in a 3 mm thick galvanised steel sheet.
The folding system consists of a sheet (PVC-coated fabric) strengthened internally by galvanised steel tubes placed inside welded pockets. The diameter of the strengthening tubes varies according to the resistance class for the required air pressure. The sheet assembly is lifted thanks to belts secured above the winding shaft.
