SOMMER Fire Doors B·S·T® DIN - fire resistance class T30 and T90 according to German Standard
The SOMMER B·S·T® DIN fire protection doors have been tested according to DIN 4102. The torsion resistance and compressive strength of the doors is ensured by the galvanized or primed 1.5 mm sheet metal and the door leaf with a thickness of 63 mm. The two three-part galvanized construction hinges ensure ease of movement and long-term use. As standard, a corner frame from 2.5 mm thick, galvanized and primed steel sheet is used for the self-closing fire protection door with an overhead door closer. Alternatively, block and surrounding frames are possible. The SOMMER B·S·T® DIN fire protection doors are combinable with other safety requirements, e.g. smoke protection, burglary protection and bullet resistance.
