The concrete door collection presents modern style doors with real concrete cladding and wood-like lucobond, with a unique design and unusual lines. Notes Do not bring the door in direct contact with water and/or direct exposure to the sun. Water will not harm the durability of the door itself or the thermal insulation, but it may damage the galvanization of the steel and cause it to rust over time. An entrance door does not completely seal the ingress of water, so it is recommended to install a canopy over the door area. Hi-Tech armored doors are suitable for installation in private houses and villas.
