steel panel fire rated EI30 / EI60 doors in custom size

Fire-rated EI30/EI60 steel doors

with a flat rebate are a robust construction of high technical parameters with a perfect installation system in commonly used building materials and various installation conditions. A door leaf with a thickness of 64 mm and three-sided or four-sided flat rebate, made of steel sheet with a thickness from 0.75 to 1.0 mm, galvanized and electrostatically primed in the white color as a standard, filled in with fire-resistant sandwich panel bonded on both sides to the sheets of the door leaf sheathing over the whole surface. Fire-rated door leafs are manufactured in non-standard dimensions with a maximum length of 1250 mm and height of 2500 mm. Door frames are made of a steel sheet with a thickness from 1.5 to 2.00 mm with a three-sided profiled keyway under EPDM gasket. Door frame profiles being available: corner, surrounding, or fixed door frames that ensure easy, robust, and aesthetic installation in concrete and masonry walls, as well as in lightweight drywalls. Under the standard related to the equipment of fire-rated doors, there are two or three three-part DomoGenius LHE hinges, including a spring-loaded door hinge allowing automatic closing of the doors as well as construction hinges with smooth adjustment of a door leaf position ± 4 mm.

Standard fittings for fire-rated steel doors: a lock according to DIN 18250 prepared for door lock cylinder installation, a handle according to DIN 18255 made of plastic with a steel core on a plate in the black color. Fire-rated double-leaf doors have SR 390 closing sequence regulator and an automatic door latch of passive door leaf. Doors construction allows to equip them with a wide variety of non-standard accessories, which are used in the most demanding projects: in optional version: fire escape locks and anti-panic fittings, access control, door weather strippings, glazings in a variety of dimensions and formats, automatic door opening and closing, and hydraulic door-closers.

Fire-rated EI30/EI60 steel doors with a flat rebate are products being systematically used for closing the passages of non-standard dimensions in fire division walls, which require the selection of unique fittings. The doors stand out in terms of a very favorable price to the strength of doors, which allow using them in hard conditions corresponding to class three and four of strength requirements. Such operating conditions - a great number of opening and closing cycles as well as a risk of incorrect and improper use - they require the usage of solid, fire-rated doors with 64 mm thick door board and durable hinges.

The use of fire-rated steel doors in non-standard dimensions:
For installation and operation in the area of high frequency and improper usage. Used for separation of a fire-rated staircase in multi-storey residential buildings and public facility buildings. Due to the possibilities of making the dimensions of non-standard door leafs as well as fitting the door frames, they are used in the industrial buildings, in technical areas of residential buildings, offices, and commercial-service centers.
