Fire inspection door aluminum EI20 for masonry 400x400x15

The door is made of aluminum profiles welded into an outer and inner frame. The complete assembly is joined by a solid hinge, thus allowing the door leaf to be opened when needed. In addition, mounting brackets are welded onto the outer frame. The inner leaf is fitted with a fire seal that expands many times over at high temperature and thus prevents the penetration of fire. The door infill consists of a red board, fixed using self-drilling screws.
