Commercial doors do much more than open and close. They manage foot traffic, protect property, support fire and life safety, and often connect with access-control systems. In busy buildings, they may be used hundreds of times a day.
That means choosing one is not simply a matter of finding the right size. The material, frame, hardware, fire rating, accessibility, installation conditions, and expected use all need to work together.
This guide covers the essentials, from costs and common door types to sizing, installation, repairs, and buying considerations.
What Is a Commercial Door?
A commercial door is designed for offices, shops, schools, hospitals, warehouses, apartment common areas, industrial facilities, and other non-residential or high-traffic buildings.
Compared with a typical residential door, it is usually built for:
- More frequent use
- Heavier-duty hardware
- Greater security
- Fire and accessibility requirements
- Wider or taller openings
- Access-control equipment
- More exposure to impact, moisture, and weather
“Commercial door” does not describe one particular material. A commercial door may be made from steel, wood, aluminum, glass, fiberglass, or a combination of materials. It may swing, slide, fold, roll upward, or open automatically.
It is also helpful to think of the door as part of a complete opening. The door leaf, frame, hinges, lock, closer, seals, glazing, and access-control hardware must be compatible with one another.
How Much Does a Commercial Door Cost?
Commercial door prices vary widely. A basic door slab may cost a few hundred dollars, while a complete fire-rated, automatic, oversized, or security-focused opening can cost several thousand dollars.
Typical planning ranges include:
| Product or Package | Approximate Price |
|---|---|
| Basic commercial door slab | $350–$900 |
| Hollow-metal door and frame package | $800–$2,000 |
| Fire-rated steel assembly | $1,000–$3,500+ |
| Commercial wood door | $700–$2,500+ |
| Aluminum storefront entrance | $1,500–$5,000+ |
| Automatic entrance system | $3,000–$10,000+ |
| Specialty or high-security door | Custom quote |
These figures are only general estimates. Final pricing depends on the size, material, core, frame, finish, fire rating, glazing, hardware preparation, freight, installation, and site conditions.
When comparing quotes, check whether the following are included:
- Door and frame
- Hinges, lock, closer, or exit device
- Thresholds and weather seals
- Glazing or louvers
- Fire-rated labels
- Factory hardware preparation
- Freight
- Removal of the old door
- Installation
- Painting or finishing
- Access-control work
The lowest door price is not always the lowest project cost. Compare complete openings with the same scope of supply.
What Are the Advantages of Commercial Doors?
Durability
Commercial doors are designed for regular use and can be specified for different traffic and abuse levels. A busy school corridor, warehouse entrance, and private office do not need the same door construction.
Security
They can support reinforced frames, heavy-duty locks, continuous hinges, exit devices, electric strikes, card readers, and other access-control equipment.
Fire protection
Steel and wood commercial doors are available as fire-rated assemblies. When properly specified and installed, they can help protect openings in fire-rated walls and corridors.
Design flexibility
Commercial doors are available in painted steel, stainless steel, wood veneer, aluminum, glass, fiberglass, and many other finishes. They can be practical without looking industrial.
Lower long-term maintenance costs
A correctly specified door may cost more at the beginning but require fewer repairs and replacements over time, particularly in high-traffic buildings.
What Are the Disadvantages of Commercial Doors?
Commercial doors generally cost more than residential doors. Heavy-duty materials, reinforced frames, fire labels, custom fabrication, and commercial-grade hardware all add to the price. Ordering can also be more complicated because the buyer needs to confirm the handing, wall type, frame depth, hardware preparation, and other technical details.
They are also heavier and less forgiving during installation. A frame that is slightly twisted or out of level can cause the door to drag, fail to latch, or close unevenly. For this reason, professional installation is usually the safer option.
Some doors also require ongoing maintenance. Steel finishes can be damaged, closers and hinges wear over time, and automatic or access-controlled openings need periodic inspection and adjustment.
What Are the Main Types of Commercial Doors?
Hollow-Metal and Steel Doors
Hollow-metal doors use steel face sheets over an internal core. The core may be honeycomb, polystyrene, polyurethane, or steel-stiffened construction.
They are commonly used in:
- Warehouses
- Stairwells
- Schools
- Mechanical rooms
- Hospitals
- Service entrances
Their main strengths are durability, security, fire-rating options, and compatibility with commercial hardware.
Commercial Wood Doors
Commercial wood doors are often used in offices, hotels, healthcare facilities, schools, and other interiors where appearance matters.
They offer a warmer architectural look than steel but still require the correct core, edge construction, finish, and hardware reinforcement for the intended use.
Aluminum Storefront Doors
Aluminum storefront doors are common in retail shops, restaurants, offices, and public entrances. They usually combine an aluminum frame with a large glass panel.
They provide visibility and a clean appearance but require compatible pivots, locks, closers, thresholds, and access-control hardware.
Full-Glass Doors
Full-glass doors are often used in offices, showrooms, hotels, and interior retail spaces. They create a modern, open appearance but may offer less privacy and require careful attention to safety glazing and door weight.
Fire-Rated Doors
A fire-rated door is a tested performance category rather than a single material type. Fire-rated doors may be made from steel, wood, or other approved materials.
The required rating applies to the complete assembly, including the frame, hardware, glazing, and other components.
Automatic Doors
Automatic sliding, swinging, and folding doors are used in hospitals, airports, grocery stores, hotels, and accessible entrances.
They require sensors, controls, power, safety devices, and regular maintenance in addition to the door itself.
Roll-Up and Sectional Doors
Roll-up doors coil above the opening, while sectional doors move upward in connected panels. They are commonly used at loading docks, warehouses, storage facilities, service counters, and parking structures.
What Are the Standard Sizes of Commercial Doors?
There is no single size for every commercial door. However, standard steel door dimensions provide a useful reference.
ANSI/SDI A250.8 lists standard single-door opening widths from 2 feet to 4 feet and common heights including 6 feet 8 inches, 7 feet, 7 feet 2 inches, 7 feet 10 inches, and 8 feet, depending on door thickness and construction. The standard also recognizes both 1⅜-inch and 1¾-inch doors, although the heavier-duty levels generally use 1¾-inch construction.
How Tall Are Commercial Doors?
Common commercial door heights include:
- 80 inches, or 6 feet 8 inches
- 84 inches, or 7 feet
- 86 inches, or 7 feet 2 inches
- 94 inches, or 7 feet 10 inches
- 96 inches, or 8 feet
The 36-by-84-inch commercial door is especially common in current retail inventories, but the correct height depends on the building plans, existing frame, ceiling conditions, required clear opening, and local code.
How Thick Are Commercial Doors?
The most common thickness for heavy-duty commercial steel and wood doors is:
1¾ inches
Some standard-duty steel doors are also available at:
1⅜ inches
Thickness affects the frame, hinge, lock, edge preparation, glazing kit, and other hardware. A replacement door should not be ordered by width and height alone.
How Wide Are Commercial Doors?
Standard single commercial steel door widths commonly range from:
24 to 48 inches
Frequently used nominal widths include:
- 30 inches
- 32 inches
- 34 inches
- 36 inches
- 40 inches
- 42 inches
- 48 inches
Pairs of doors may use two equal leaves or unequal leaves.
Nominal Size vs. Rough Opening
The door size, frame opening, and wall rough opening are different measurements. The required rough opening depends on the frame profile, wall construction, anchors, and manufacturer.
Always use approved drawings or the manufacturer’s instructions rather than estimating the opening from the door size alone.
How to Install a Commercial Door?
Commercial door installation normally begins with verifying the opening, wall type, door size, handing, frame depth, hardware locations, and finished-floor height. The frame must then be installed square, level, and plumb before the door is hung.
Once the frame is secure, the installer fits the hinges, door, lock, closer, threshold, seals, and any access-control components. The completed door should swing freely, close at a controlled speed, latch consistently, and maintain even clearances around the frame.
Because commercial doors are heavy and small alignment errors can create long-term problems, professional installation is strongly recommended. It is particularly important for fire-rated, automatic, glass, oversized, and electronically controlled openings.
How to Repair a Commercial Door?
Many commercial door problems are caused by loose hinges, worn hardware, frame movement, closer problems, or poor alignment. Common signs include rubbing, sagging, slamming, difficult opening, failure to latch, and sticking exit devices.
Minor issues may be corrected by tightening hardware, adjusting the closer, realigning the strike, or repairing the finish. However, replacing parts without identifying the real cause can make the problem worse. A door that does not latch may have a lock problem, but it may also be sagging or installed in a twisted frame.
A commercial door technician should handle structural damage, failed exit hardware, automatic-door problems, access-control faults, and fire-rated openings. Unapproved drilling, cutting, or hardware changes may affect the performance or rating of the assembly.
How to Choose a Commercial Door?
Start with the way the door will be used. Consider its location, traffic level, exposure to weather or moisture, security needs, required hardware, appearance, and budget.
Material matters as well. Hollow-metal doors are well suited to high-traffic and security-sensitive areas, wood doors are popular in architectural interiors, and aluminum-and-glass doors are commonly used for storefronts and public entrances.
Check ADA Accessibility Requirements
For doors on an accessible route, key ADA considerations may include:
- Clear opening: At least 32 inches, measured with the door open 90 degrees
- Hardware height: Generally 34 to 48 inches above the finished floor
- Threshold height: Generally no more than ½ inch
- Opening force: Generally no more than 5 pounds for applicable non-fire doors
- Operation: Hardware should not require tight grasping, pinching, or wrist twisting
- Maneuvering space: Enough clear floor area must be provided around the doorway

Not necessarily.
The ADA generally requires a minimum clear opening of 32 inches, measured between the face of a swinging door and the opposite stop when the door is open 90 degrees. This refers to the usable passage width, not simply the nominal size printed on the door.
Hinges, frame stops, door thickness, and the opening angle can all reduce the available clear width. For this reason, a nominal 36-inch door is often used where a 32-inch clear opening is required, although the completed assembly should still be checked for compliance.
Confirm Fire-Rated Requirements
When a fire-rated opening is required, the door, frame, glazing, seals, and hardware must be compatible as part of a complete assembly. The required rating should follow the approved building plans and applicable fire code.
Review SDI and BHMA Standards
SDI guidance can help determine the appropriate construction and performance level for steel doors and frames. BHMA standards provide similar guidance for commercial locks, hinges, closers, exit devices, and other hardware.
Check Local Codes
Requirements vary by project and location. Before ordering, review the approved plans and confirm the applicable building, fire, and accessibility requirements with the local Authority Having Jurisdiction, or AHJ.
Where to Buy Buy Commercial Doors?
Commercial doors are available from manufacturers, specialist distributors, local installers, building-supply retailers, and online suppliers. For standard openings, retailers or online sellers may be convenient. For custom sizes, fire-rated assemblies, specialty hardware, or complete door-and-frame packages, working with an experienced supplier is usually the better choice.

FAQs About Commercial Doors
A commercial steel door is generally built for heavier use, stronger hardware, and stricter safety or security requirements. It may also be prepared for commercial locks, exit devices, closers, access-control systems, and fire-rated assemblies. Residential steel doors are usually lighter and designed for less frequent use.
Yes, when they are properly specified and installed. Commercial glass doors typically use safety glazing such as tempered or laminated glass. Depending on the project, they may also include reinforced frames, access-control hardware, panic devices, or impact-resistant glass.
The price depends on the material, size, frame, hardware, glass, fire rating, and installation conditions. A basic commercial door may cost several hundred dollars, while a complete glass, automatic, fire-rated, or access-controlled entrance can cost several thousand dollars.
