Henan fireproof door What are the specification requirements for height and width dimensions

about fire-proof door The size requirements mainly include two points: Henan fireproof door is the size limited in the inspection report obtained by the manufacturer, and the size required by the relevant department documents. The former is the procedural approval, and the latter is temporarily adjusted according to the actual situation.

according to Henan fireproof door manufacturer It is required to obtain the fire door inspection report, and the products of corresponding grades and materials can be produced within the approved size range. If the enterprise has obtained the qualification of 1521 double door of steel grade A, then it can produce steel grade A fire doors between 1m and 1.5 sizes. Other sizes are the same as this; It is enough to make sure that the product material, fire resistance rating and opening type are correct.

The facilities specified in the new size of Henan fire door completely broke the previous specification requirements, limiting the height and width of fire door to 2123, i.e. 2100 mm wide and 2300 high; The 2400, 2700, 3000, 3300 and other sizes that can be produced in the past will not be produced.

The size of 2123 is enough for general use places, but for some places where the door openings are needed, such as workshop, power distribution room, diesel engine room and other places, some can not meet the demand, but it is difficult to find manufacturers of large size fire doors in the market, which makes people very distressed. Many users find products.
