Fire Protection Shafts

Each door leaf is made of two steel plates 1.00 mm thick (alternatively 1.25, 1.50 mm thick) in the form of a sandwich. The thickness of the doors for the doors 60 and 120 min is 60mm. Internally they include stone wool with a density of 150 kg / m3.

Each leaf has strong steel fire-resistant hinges. The lock is steel, fireproof, with or without panic function. The pole and the handle are fireproof with a plastic finish. Securing the air and smoke barrier is achieved with a heat-insulating, mineral-based tape that swells at temperatures above 120 ° C.

Door frames are made in two ways:

The frame consists of 1.50-2.2.00 mm thick steel roller, of special ‘Z’ shape and is placed in the door opening regardless of wall thickness. The frame of this form is the most economical solution and the most widespread.
The complete wall covering frame consists of 1.50-2.2.00 mm thick steel rolling, which covers the entire wall thickness (road-hepatic). The vacuum of the case is filled with cement mortar.

The door leaf and the frame are delivered dyed with primer and anti-rust paint.

In case of airtightness requirement, the frames provide a rubber interference socket.
