BOXTWOFOLD

BOXTWOFOLD double-layer folding high-speed PVC doors are made from 900 gr/m² PVC tarpaulin material. The double-layer PVC tarpaulin is reinforced with 120x55 aluminum extrusion bars mounted at four separate points. The doors operate on the principle of pulling the double-layer PVC curtain mechanism upwards from below using reinforced aluminum bars. This is achieved by means of belts wound around a shaft, and a gearbox and motor connected to the shaft drive the galvanized uprights on either side, which in turn move along the guide rails.
