- Commercial Steel Doors: Commercial steel doors are designed for heavy-duty use. Often classified by architects as hollow metal doors, commercial metal doors are specified for interior, exterior and fire-rated applications. Commercial metal doors are a versatile, durable, and cost-effective commercial door solution.
- Hollow Metal Doors: Commercial steel doors are often listed on architectural plans as hollow metal doors or by the abbreviation HM. Commercial steel doors are made from roll form steel with a non-metallic core that fills the cavity space inside the door. Typical core materials include polystyrene for improved insulating value and Kraft Structural Honeycomb for moderate insulation and improved rigidity. Hollow metal doors are strong, resistant to flames and known to withstand significant impact.
- Fire Rated Steel Doors: Fire rated steel doors are available with 20, 45, 60, 90-minute, and 3-hour fire labels. Fire rated metal doors are designed to withstand smoke, flames, and toxic gasses while occupants exit the building. Hollow metal doors are frequently used in stairwells, corridors, entrances, elevator shafts, boiler rooms and other areas where a fire-rated metal door is required.
- Fire Rated Steel Doors with Glass: Fire rated steel doors are available with either non-wired ceramic glass, or impact-safe wire glass. Fire rated metal doors with wire glass are frequently used for industrial metal door applications and areas where an increased sense of safety or security should be observed.
- Exterior Steel Doors: Commercial steel doors are designed for use in exterior door applications. For added longevity exterior metal doors are manufactured with galvanneal or galvanized steel and factory applied epoxy primer. Exterior metal doors typically include a polystyrene foam core for insulating value. For superior insulation, exterior metal doors with a polyurethane pressurized foam core should be specified.
- Interior Steel Doors: Interior steel doors are manufactured with a factory applied primer that can be painted to existing or scheduled finishes. Interior steel doors may include flush, 2- or 6- panel doors, and a wide range of vision lites and glass configurations. Interior metal doors are frequently used in applications where a heavy-duty, cost-effective, or fire-rated interior door is needed.
- Industrial Metal Doors: Industrial steel doors can be manufactured from 18-, 16-, or 14- gauge steel. Additionally, industrial steel doors can be manufactured from cold-rolled, galvanized, galvanneal and stainless-steel material. Industrial steel doors may require properties for corrosion resistance, fire resistance, radiation resistance, resistance to microbial growth, durability, security, odd sizes, odd shapes, custom hardware prep and more.
- Steel Security Doors: Commercial steel doors naturally offer increased security compared to most of their residential counterparts. 18-gauge hollow metal doors are classified by the Steel Door Institute (SDI) as physical performance level 2, heavy-duty. Optional features such as a steel-stiffened core construction, 16- or 14- gauge steel, and security door hardware can further improve the security properties of a metal door assembly.
- Steel Double Doors: Steel double doors can operate in several configurations. Pairs of metal doors can be hung as active/inactive pairs where one door functions as the primary door and the other remains fixed until it’s disengaged. Another configuration hangs two doors, both active. In most cases active/active doors are used with surface vertical rod exit devices that latch each door at the top and/or bottom, allowing each door to operate independently.
- Steel Doors with Glass: Commercial steel doors with glass allow occupants to see through a door before it is opened. Commercial structures require metal doors with impact resistant, tempered glass that’s designed to prevent injury from any incidental human impact that may occur. Typical configurations may include metal doors with square-, rectangle-, half-or full- lite glass.
- 6-Panel Steel Doors: Commercial 6 panel steel doors are made with a single sheet of roll form embossed steel. Commercial 6 panel metal doors are typically made from 18-gauge steel with a polystyrene insulated core. Commercial 6 panel doors are designed for heavy-duty use and recommended for motel and hotel doors, exterior doors, entry doors, fire-rated doors, and locations where a heavy-duty hollow metal panel door is needed.
- 2-Panel Steel Doors: Commercial 2 panel steel doors are typically manufactured with 18-gauge steel with a polystyrene insulated core. Commercial 2 panel doors are made for heavy-duty use and used in motel and hotel door openings, exterior door openings, unit entry doors, and fire-rated openings where a heavy-duty steel 2 panel door is needed.
