EI30 fire-resistant steel doors with increased RC4 resistance to burglary

Anti-burglary steel panel doors are structures that ensure a high level of safety and robust workmanship.

A 62-mm thick leaf with a three-sided thick rebate manufactured on a glued laminated wooden rail with steel sheathing 1.0 mm thick joined at three edges by folds forming a leaf rebate. Filling glued on double sides to the frame and sheathing consists of two mineral wool panels with 120 kg/m3 in density and toughened steel enforcements. A silicon rebate gasket is placed in a rebate groove of an anti-burglary fire-resistant door leaf, whereas in the lower edge, there is an expanding gasket strip. The lower edge of the leaf can be finished with a profile with an embedded automatic dropping seal or an adjustable coffer with a 15-50 mm extension and a comb seal. The door leaf of anti-burglary fire-resistant doors at the hinged side is equipped with three protecting tenons. 

A standard set of anti-burglary fire-resistant doors comprises a block frame with a fixed width of 94-mm made from zinc-coated steel sheet 1.5 mm thick, intended for concreting, mounted with Ø10 bolts in a rebate with a mounting doorstep. An expanding gasket is placed in the side jambs and the frame crossbar A placed finishing doorstep is available in the option for doors with an adjustable coffer. It is possible to use an angle frame or manufacture a frame based on an individual design. Fire-resistant and anti-burglary doors are equipped with three-piece structural hinges with adjustment in two planes, screwed in seats of hinges of a leaf and a frame. The pins of the hinges are protected against being knocked out. Hardware fittings: a main spreader multi-bolt and multi-point lock in class 6 with a 6 class cylinder insert with a set of keys made on the basis of a code card, and as an option, an additional inserted multi-point bolt lock with an insert with a knob on the internal side, a handle - a steel handle in satin colour on a safe shield on a safe disc protecting the insert of the main lock on the external side.

Physical properties of anti-burglary fire resistant steel doors

The doors are manufactured in EI²45/EW30 fire resistance class under PN-EN 13501-2:2008
The doors meet the criteria of RC-4 class of resistance to burglary under EN 1627:2012 and class C under PN-90/B-92270
Class 3 of mechanical resistance in compliance with PN-EN 1192:2001

Uses:

EI30 fire resistant and RC4 anti-burglary doors

are intended for use in places with a high risk of burglary as a closure of openings in internal walls, where EI30 fire resistance is required. Owing to the combination of high parameters of anti-burglary resistance, fire resistance and acoustic insulation, anti-burglary fire-resistant doors are commonly used in multi-family residential buildings as internal entrance doors between a staircase and a flat. They are recommended to be assembled in rooms free of dampness, dry and with good ventilation. They are often installed as closures of server rooms, office rooms and technical rooms.
