Inquiry (采购产品): 2 hour fire rated steel door Hi, I need to put in a 2 hour fire rated steel door in a concrete block wall to allow access to a boiler room. I was wondering if you could email me a list of standard 2 hour fire rated steel door sizes that you have in stock, so that I can determine what size to cut my door opening or if I need to order a special size door.
