摘要

The door leaf is made of several flat nontwist slats (110,111,112,113) which adjoin at their edges top and bottom and reach right across the door opening. The slats are joined together by a U-profile or angle rail to form a stable entity at their edge faces. The top and bottom edge faces of the slats are convex and concave or vice versa and the slats are made of rigid foam with top and bottom sides made of fixed layers preferably of plastics. The door frame is galvanized and takes apart, being coated outside in film.
