现在市场中门的分类是非常丰富的,在使用的过程中各种类别的门会根据使用的需求来发挥不同的性能优点。那么钢质防火门的分类有哪些呢?在现在国内的钢质防火门市场中主要是分为甲级和丙级和一级三种级别分类的产品。如果我们从材料来进行分类的话,那么会有钢制以及木质的防火门。什么是甲级的防火门呢?也就是说这种级别的产品耐火极限还是较为不错的,一般为一点五个小时,而对于一级别的产品来说它的耐火极限会比甲级的防火门要少多出半个小时的时间。对于丙级的防火门产品来说它的耐火极限能够达到半个小时的时间。这也告诉了我们众多的消费者,在购买钢质防火门之前要根据自己的使用需求来进行产品的购买。也要根据闭门器的安全位置以及房屋装修的情况来选购,这样才能够购买到最适合的产品。钢质防火门厂家 本文地址:http://dlhfmc.com 180.
