Commercial Steel Door Performance Level

Standard for Most Commercial Doors

Level 2 | 18ga.

18 gauge steel doors are classified as physical performance level 2 for heavy-duty commercial durability.

Level 3 | 16ga.

16 gauge steel doors are classified as physical performance level 3 for extra heavy-duty commercial durability.

Level 4 | 14ga.

14 gauge steel doors are classified as physical performance level 4 for maximum commercial durability.

Materials & Finishes

Standard for Most Commercial Doors

Steel Door Materials & Finishes

Cold Rolled Steel | Prime Coat

Cold rolled steel is made by adding tensile force to hot rolled steel sheets. The cold-rolling process increases density, hardens the steel, and produces a consistent surface that’s ideal for commercial doors and frames.

Standard for Most Commercial Doors

Steel Door Materials & Finishes

Galvanneal | Prime Coat

Galvanneal steel is produced when cold-rolled steel is dipped into liquified zinc then heated until a new zinc-iron alloy is created. Galveanneal steel doors are known for their improved corrosion resistance and superior paint adhesion properties.

Steel Door Materials & Finishes

Galvanized | Prime Coat

Galvanized steel is produced when cold rolled steel is dipped in a hot zinc coating. Galvanized steel doors are resistant to corrosion but offer poor paint adhesion compared to annealed steel doors.

Commercial Steel Door Models

Standard for Most Commercial Doors

Steel Door - Model 1

Model 1 | Full Flush

Full flush commercial metal doors are formed with a visible seam at the door edge.

Model 2 - Seamless Edge

Model 2 | Seamless

Seamless edge steel doors have filled, finished, and prime-coated vertical edges.

Hollow Metal Door Cores

Standard for Most Commercial Doors

Steel Door - Polystyrene Core

Polystyrene

Polystyrene provides a hollow metal door with rigidity, resistance to dents and insulating properties.

Standard for Most Commercial Doors

Steel Door - Honeycomb Core

Honeycomb

Resin-hardened honeycomb core stabilizes a hollow metal door and provides resistance to impact and dents.

Steel Door - Steel Stiffened

Steel Stiffened

Steel stiffened doors have steel reinforcements welded inside the door cavity. Insulation is used to fill any air space.

Steel Door - Polystyrene Core

Temp Rise

Temperature rise doors have a mineral composite core that reduces heat transfer to the non-fire side of a door.

Steel Door – Urethane Core

Urethane

Polyurethane foam is expanded inside the cavity of a hollow metal door to improve insulating values.

Specialty Door Cores

STC or acoustical doors are used in studios, theaters and applications where audible noise is a concern.

Lead lined doors resist the transfer of radiation in medical, energy and aerospace facilities.

Ballistic doors are designed for use in areas where a firearm is likely to be discharged.

Blast doors are designed to protect building occupants and property during an explosion.
