Fire Exit Doors
(For Pharmaceuticals, Cosmetics, Food and Hospitals)
1- Description of the structure and technical data:
|Deflection||≤15mm, safety coefficient K ≥ 3Test condition: span of both ends of the fulcrum is 3 M, the concentrated load is 100 kgs|
|Thermal Transmission Coefficient K （W/M2.K）||0.75 – 0.85 according to the working condition of test environment|
|Temperature for Use||– 40 ℃ to +80 ℃|
|Fire resistance||≥1.00hafter 1 hour Grill, the panel does not lose the integrity and, in back surface ,average temperature rise 133 ℃|
1.3- External Plate: Color steel sheet of 0.5 mm in thickness.
1.4- Manufacturer: Baoshan Iron &steel CO.,LTD Shanghai China
The color steel sheet is produced by means of pre-treating, coating, baking and post processing with continuous, ie the method of the roll coating by using a hot-galvanized steel sheet as the base plate.
1.5.1- Pre-treating: The steel base sheet coil would form a film of a combined
metal oxide after de-greasing, rinsing, chemical conversion process and sealing treatment, sequentially improving the coat’s adhesive force and the finished product’s corrosion resistance.
1.5.2- Coating & baking: The process consists of a double-coat and double-bake.
First, coat the polyester primer with good adhesive force on the pretreated base plate, upon baking, then make the top color coat of silicon modified polyester of22 micro in thickness with good weather and corrosion resistances and 2nd baking, thus finally gain the color coated steel sheet with beautiful appearance and good quality.
1.5.3- The product then be coated with wax, covered with protective film and coiled. This coated steel sheet has such advantages as not only light weight, smooth and beautiful appearance of the surface, but good resistance to weather, damp and chemicals, easy to clean and disinfection etc.

3- Internal insulation Core
The Internal insulation Core of the partition panel adopts the magnesium oxide modified industrial board , double skin gypsum and industrial fire resistance honeycomb sheets treated specially.
3.1- The modified magnesium oxide board has the merits of non-combustible, non-toxic, damp-proof etc. used as one of the inner core plate and lined by the color steel sheet may further increase the intensity and fire performance of the color steel panel. Used widely as a structure material of the partition panel in clean room project.
The industrial fire resistant paper honeycomb with a special treatment, has the merits of damp- proof, non-combustible, non-toxic, anti-mold, light, compression, and other characteristics. Other than plate structure, Honeycomb has a maximum strength-to-weight ratio, approximate isotropic, structural stability of good tensile. has good toughness and resilience, good sound and thermal insulation performance. It is also a very good green environment protection material.
3.2- The technical data of the internal insulation core
3.1- Frame skeleton is made of galvanized channel profile steel with 1mm in thickness. The frame skeleton of the galvanized channel profile steel not only increase the strength of the panel but also ensures the panel to combine with the shape connection profile being no open joint and the levelness of the panel partition.
