BT2 door is designed for refl ected blast pressure on door surface up to 28 bar (2,8 MPa; 406 psi); blast resistant calculated by FEM Analysis for refl ected blast pressure up to 28 bar (406psi). Pressure-Impulse-Diagram calculated by Fraunhofer Institute for High-Speed Dynamics, Ernst-Mach-Institute, EMI, for diff erent kinds of blast loads and description of the corresponding failure mode, Report I-11/15
Door is locked with round pins (dia 80 mm) and central bolt work, locking way 50 mm; each leaf is hinged with strong hinges in vault style, which allows door opening 180°, hinge pins are machined and polished from 80 mm diameter steel, rotating in sinter bushing, pins are hardened in a range of 38 to 40 HRC.
with composite filling
The heavy steel frame is constructed from 400 mm by 400 mm bended angle and prepared with anchoring studs.
Door finish: door painted with primer resisting corrosion.
are provided as recommended for reinforced concrete doors; the seals are typically used for reinforced concrete doors to improve the weather seal and provide door silencer; sealed doors have full door perimeter and all door penetrations sealed; perimeter seals are rubber gasket type; gaskets are removable, capable of sealing the mating surfaces and resistant to the atmospheric environment; the gaskets cushion the impact of the door against the frame so that steel to steel contact is not made during closing.
