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).
