    Steel fire door procurement key points.

    At this year's consumer rights protection day, CCTV exposure after a number of companies produce fake fire extinguishers, fire control products safety has attracted the attention of a great national governments at all levels, in the daily fire equipment and products inspection and test, the unqualified products do not flow to the market!

    In the fire door industry, the product is good and evil people mixed up, in order to make the customers with high quality products, ole doors and Windows company provides for the general customers the following relevant knowledge about steel fire doors when the choose and buy for everybody to understand!

    First, the normal manufacturer of fire prevention door must have the qualification of production qualification recognized by the fire assessment center, that is, the type approval certificate and inspection report of this type of steel fire door.

    Second, the steel fire door raw material is steel plate, now the market mainly USES cold rolled plate and galvanized steel plate two kinds, cold rolled plate price is cheap, but the effect of flame retardant is worse! The price of galvanized steel sheet is high, but the effect of heat insulation is better than that of cold rolled plate!

    Third, too cheap price should be considered carefully! Because of high quality steel fire door USES the price of raw materials are usually on the high side of fire prevention materials for special purpose, some manufacturer in order to reduce production cost and the unqualified products, not only for the use of the products after brings hidden trouble, at the same time when the fire control acceptance will also bring unnecessary trouble to the customer!

    Fourth, factory strength inspection! Regular fire steel door manufacturers have strict requirements on production processes and production workshop, the workers' demands are higher than general door factory, so when considering cooperation with the best the supplier can be field trips! Due to steel fire shutter, has its own advantages, therefore, although the amount of steel fire shutter will be less and less, but it will still exist on the market, it could eventually be fixed in a smaller market share from 10% to 20%, the main reason is that steel fire shutter without fire, it can be used as a security door, such as shopping malls in the import and export of the fire shutter when security doors can be used, and the cloth of fire shutter can only fire not guard against theft. At present, this market is more chaotic, especially in the hebei ren qiu area, they produce fake products in the form of "pilfering", and carry out the price. Fireproof roll curtain as a kind of emergency fire protection equipment, when no accident, only from the outside can not see its quality. Only when there is a real fire, something will happen. Moreover, in the acceptance, only from the surface, can not judge true or false.

    In addition, some developers and builders are aware of these problems, but many people only ask for acceptance, regardless of whether the product really meets the standards. Industry insiders suggest that the relevant supervision department should conduct strict inspection and supervision of market products to reduce fake and shoddy products and crack down on malicious competition. With the development of social economic construction, the new architectural type production process and installation of fire shutter technology put forward higher requirements, such as some exhibition center, in need of some large span fire shutter. In the face of these new market demands, the original production methods and processing methods no longer apply. Therefore, the company will customize according to different fire shutter, and send special technicians to install.
