30/60/90/120mins Metal Fire Exit Doors Honeycomb Paper Filled
Large openings need a large door, but since fire doors are operated
by manual, one
piece is too heavy. It's better to make it as two-leaf door.
Product Introduction
Zowor steel fire exit door and frame are both labled with UL mark.
Door slab is 45mm thick consisting of 1.0mm gal. steel sheet on
both sides and 43mm thick kraftpaper as fire door core. Besides,
glues brushed to paste kraftpaper and face steel are also
fireproof. By the way, face sheet can also be 1.0mm stainless steel
sheet which doesn't need powder coating or wood grain finish
normally. But if the face sheet stays galvanized steel, usually it
need to be with powder coating or heat transfer paper with wood
texture treated on door surface to enhance its anti-corrosion
performance and beauty as well.
As far as door measurement is concerned, it is grouped in single
swing doors and pair doors. For single doors popular size is about
3 feet wide by 7 feet high(915mm*2134mm) and no larger than 4
feet wide by 8 feet high(1200*2403mm); meanwhile for pair doors
popular size is 6 feet wide by 7 feet high(1828mm*2134mm) and no
larger than 8 feet wide by 8 feet high(2403mm *2403mm).
