Our double-walled, insulated roller door 4020 is made of aluminum profiles. It is equipped with a lintel seal and a primed winding shaft. The drive is a direct mount drive 400 V (three-phase voltage). Standard equipment includes an emergency crank handle and crank and an integrated anti-drop device. The roller door profile 4020 in coil-coated design is particularly suitable for use near the sea (corrosion) or in agricultural environments (stables). Even in relatively aggressive (e.g. chemical) environments, the aluminum profile 4020 is more corrosion resistant than galvanized steel.
