Hinge system: We use 1/2″ x 1″ bar stock with a 3/8″ hinge pin for rugged durability even in the most demanding commercial applications.
Frame: Our strong 3″ x 3″ x 1/4″ angle iron frame is welded to our exact dimensions and all the seams are ground smooth for the correct fit and a professional finish that will last for decades.
Handle: All Steelway diamond plate doors have a 3/8″ round rod handle on the right door for easy pull-up and no maintenance. We use our recessed Steelway handle whenever possible.
Padlock tabs: Keeping your access secure is as easy as specifying where you want your padlock tabs. Just tell your salesperson what your locking needs are and we will solve your problem.
Safety chain: We can install a safety chain that protects the front of the door opening from accidental fall-ins. If you intend to have the doors open for ventilation, this option is a must.
Rebar studs: If this is a new construction, we can weld #4 rebar studs under the frame to make sure the unit is permanently secure.
