Hollow metal doors are ideal for commercial doorways, as they provide high performance function, durability, and cost-efficiency. Daybar is a respected leader in the hollow metal door and frame industry, offering superior quality and workmanship.

Hollow metal doors can be used in a variety of applications including manufacturing plants of all kinds, office buildings, hospitals, schools & universities, stadiums, dealerships, hotels, farm buildings, the food service industry, and much more.

Hollow metal doors need no special core to meet fire-safety requirements. Our hollow metal doors are ISO 9001 quality system certified with Intertek WH 3HR approval for single swing steel doors and frames.  Hollow metal doors come with an FM approval 1.5 – 3HR test report and certification for steel doors and frames up to 8 feet wide by 8 feet high.

Hollow metal door cores include:

• Honeycomb core
• Polystyrene core
• Urethane core
• Mineral fireproof board

Doors and frames are prime painted with lead free epoxy resin. All top, bottom and side closers are fabricated by 16 GA stiffeners welded to front and back of skins.

Seidl Door & Glass Hollow Metals is a supplier and fabricator of hollow metal door frames.

Hollow metal door frames come in a variety of depths, widths, and heights. Hollow metal door frames are used for various applications including:

• Single door egress
• Double door egress
• Borrowed-lite frames
• Cased openings
• Side-lite frames
• Transom frames

Hollow metal door frames are typically made of 16 GA steel and come either welded or knock-down (KD).  Welded hollow metal frames have a 3HR fire rating.  Knock-down hollow metal frames are labeled for 90 minutes.  A knock-down hollow metal frame is primarily used on an interior application where a wall is already in place.  A welded frame can be used for new construction or replacement, generally in exterior masonry openings and interior commercial build-outs.

Hollow metal frames can be customized and fabricated to accommodate just about any type of opening imaginable.  Steel frames have become the standard for commercial use because of the low maintenance, durability,  and cost-effectiveness of the material.

Seidl Door & Glass Hollow Metals is a distributor for DORMA door closers

Seidl Door & Glass Hollow Metals is conscientious about it’s customers, so as a courtesy to our customers special fasteners are included to accommodate the application for which the product will be used.  In addition, we stock the heavier powered door closers with a heavy-duty arm and parallel arm bracket, dust covers are included. All door closers comply with ADA and meet barrier-free accessibility requirements. Our door closers are available in Aluminum (689) and Bronze – Dark Duranodic (695).

Door closers can have a dual function when fitted with certain accessories. A door closer with hold-open arm will keep a door in the open position when actuated until released. You might see this on the rear entrance to a store where the door is normally locked. When deliveries are made the hold-open feature on the door closer is actuated for convenience.

We carry two types of door closers with hold-open functionality:

• Friction type (the most common type of door closer) which works by opening a door beyond a certain degree of egress.
• Plunger type which has a mechanical thumb-turn that when desired can be engaged or dis-engaged.
