Avoid Premature Failure of Your Hollow Metal Doors and Frames
Use of galvannealed coating on cold rolled steel can make a major difference in the life of doors and frames that are exposed to moisture.
Moisture can enter a door or frame in several ways:
- From the top, for example when rain water runs down the side of the building;
- From the bottom, if there is flooding in that area;
- Through the hinge and lock preps, with water sprayed from a sprinkler.
Many specifications only call for cold rolled steel doors with factory-applied primer; however this type of coating only protects the outside surface of the door. The raw cold rolled material on the inside of the hollow metal door remains unprotected; the result is often premature failure of exterior doors.
Specifying a door with a galvannealed (hot dipped galvanized material that has been annealed) coating prevents rust and other premature aging, because galvannealing is much more durable than primer, and also because galvanneal coating is applied on both sides of the door skin.
Galvannealed coating is applied at the steel mill that produces the steel sheets; Door Components ONLY purchases steel with galvannealed coating, so every door and frame that we manufacture is protected from rust. This is our standard product – no extra charge; in fact you don’t even have to ask for it.
You can avoid premature aging by specifying galvannealed coating on every door and frame. And you can rest easy knowing that Door Components delivers this quality coating with every door and frame, at no additional charge.
