为了预防不必要的灾害,科学家发明了钢质防火门。这种防火门以钢作为材料,在两层门之间加上防火的材料,起到防火的作用,科学技术在不断的发展,现在还有了电控的防火门。这种新型的防火门当发生火灾时,可以迅速打开,便于救护。非常的实用。钢质防火门的生产过程,非常的严格,我们国家有特定的技术标准和规范,只有符合相关规定的生产,才是合格的防火门。不同质量的防火门的耐火性也不一样,所以国家的法律标准里面就根据耐火性分为了A类,B类和C类。不同的类别有不同的要求。不同的类别又有不同的代号。大家在购买防火门的时候一定要看工厂的生产批文,还有相关的执照,这样才能买到货真价实的防火门,如果买到质量低劣的防火门,一旦失火,后果将是非常严重的。钢质防火门厂家 本文地址:http://dlhfmc.com 164.
