Choosing a commercial door requires more than selecting a material and . The opening must suit the building’s use, traffic, security plan, accessibility needs, fire separations, and wall construction.
Contractors and property managers should treat each door as a complete system, including the frame, glazing, hardware, controls, and surrounding construction.
Start With the Building Use and Door Function
Door selection should begin with a room-by-room review of how people, goods, and equipment will move through the property. A retail entrance has different demands from a loading area, stairwell, or treatment room.
Before assigning a door type, confirm:
- Who will use the opening
- How often it will operate
- What must pass through it
- Whether public access is permitted
- What level of security is required
- Whether the opening forms part of a fire separation
- How much weather exposure it receives
- Whether automatic operation is needed
Compare Commercial Door Types by Application
Commercial door types should be compared according to the demands of each opening. Appearance matters, but performance, code requirements, traffic volume, and maintenance access should guide the final specification.

Storefront Doors
Aluminum storefront doors are commonly used at retail units, offices, clinics, restaurants, and other customer-facing properties. They support glass areas, clear sightlines, and a commercial appearance.
These doors work well where visibility and natural light are priorities. The project team should review:
- Frame depth
- Glass type
- Thermal performance
- Threshold design
- Locking hardware
- Closer strength
Storefront systems should also be coordinated with adjacent windows and curtain wall sections. Mismatched framing, glass thickness, or finish selections can create installation problems.

Hollow Metal Doors
Hollow metal doors are suited to service corridors, warehouses, mechanical rooms, storage areas, loading zones, and back-of-house spaces. They provide strength, support heavy-duty hardware, and can withstand use.
The frame and door should be specified together. Wall type, jamb depth, anchor style, hinge preparation, closer reinforcement, and lock preparation all affect installation.
For exterior openings, the specification may also require:
- Insulated cores
- Weather seals
- Drip protection
- Corrosion-resistant finishes
These doors are often selected for practical areas where security and durability matter more than visibility. They remain serviceable when suitable finishes and hardware are maintained.
Fire-Rated Doors
Fire-rated doors are required at specific openings identified by the building design and applicable code. Typical locations include stairwells, service rooms, corridors, exits, and fire separations.
A rated opening is a complete assembly. It may include:
- A labelled door
- A compatible labelled frame
- Approved hinges
- A door closer
- Positive-latching hardware
- Fire-rated glazing
- Smoke seals
- Listed exit hardware

Glass Doors
Glass doors are used in offices, showrooms, meeting rooms, retail interiors, and building entrances where openness and visibility are important. Options may include framed, partially framed, or frameless systems.
The design team should consider:
- Glass thickness
- Safety glazing
- Patch fittings
- Rails and pivots
- Locking hardware
- Floor conditions
- Visibility markings
Glass doors are best suited to openings where visual connection is valuable and impact risks are controlled. They may require different security planning from hollow metal or security doors.
Automatic Doors
Automatic doors support accessibility and improve movement at busy public entrances. They are common in healthcare, retail, office, and institutional buildings.
The opening may require activation buttons, sensors, safety devices, power supplies, wiring, signage, and emergency operation. Clear floor space and approach paths must also be considered.
For renovation projects, confirm whether the existing door, frame, and structure can support the operator. Some openings need reinforcement or replacement before automation can be added.
Security Doors
Security doors are used where controlled access, forced-entry resistance, or restricted movement is a priority. Applications may include storage rooms, utility spaces, data areas, pharmacies, industrial facilities, and staff-only entrances.
The door should be coordinated with the security system. Required components may include:
- Electric strikes
- Magnetic locks
- Card readers
- Door position switches
- Request-to-exit devices
- Backup power
Each component can affect the frame and hardware preparation.
Security should not interfere with emergency egress. Access control, panic hardware, fire alarm interfaces, and locking functions must be reviewed as one system.
Coordinate the Door, Frame, and Hardware
A commercial door should never be specified as an isolated product. The door leaf, frame, hinges, closer, lock, threshold, seals, and controls must operate together.
Contractors should confirm hardware sets before fabrication. Late hardware changes can require:
- New cut-outs
- Additional reinforcement
- Different wiring paths
- Frame modifications
Property managers should also consider replacement parts and service access. Standardized hardware across similar openings may simplify maintenance, key control, and future repairs.
Plan for Accessibility, Egress, and Code Requirements
Accessibility and life-safety requirements can affect clear opening width, threshold height, maneuvering space, opening force, hardware position, and door closing speed. These factors should be checked during design rather than after installation.
The door schedule should identify:
- Accessible entrances
- Required automatic operators
- Exit doors and panic hardware
- Fire-rated openings
- Access-controlled doors
- Doors connected to alarms
- Special glazing requirements
Early coordination helps prevent conflicts between architectural intent and operational requirements. It also gives electrical, security, and fire alarm contractors information before rough-in work begins.
Assess Existing Conditions in Renovation Projects
Renovations require careful site review because existing openings may not match drawings. Frames may be twisted, corroded, poorly anchored, or buried under old finishes. Floors may have changed height, and walls may not be plumb.
Before ordering, verify:
- Rough opening dimensions
- Finished floor levels
- Wall thickness
- Swing direction
- Frame condition
- Available electrical pathways
Existing fire labels and hardware preparations should also be documented.
Temporary access and construction phasing matter in occupied buildings. The team may need to maintain secure entry, emergency egress, deliveries, and customer access while doors are removed and replaced.
Budget for the Complete Opening
Door pricing should include the full opening rather than the slab alone. Frames, glazing, hardware, access control, automatic operators, finishing, removal, installation, disposal, electrical work, and site repairs can affect the project cost.
A lower cost option may suit a low-use interior room. High-traffic entrances, exterior openings, and secure areas usually benefit from stronger hardware and better preparation.
Lifecycle cost is also important. A door that requires frequent adjustment, replacement parts, or emergency repairs may cost more over time than a properly specified commercial system.
Finalize the Door Schedule Before Construction Advances
A detailed door schedule helps contractors coordinate ordering, wall construction, electrical rough-ins, security systems, and finishes. It should identify each opening, door type, frame type, size, swing, rating, glazing, hardware set, finish, and control requirements.
Commercial Door Pros can review site conditions, building use, traffic demands, and installation requirements for projects across the Greater Toronto Area.
Early technical input can help the project team reduce conflicts, control costs, and select doors that perform as intended.

Frequently Asked Questions
Who should be involved in selecting commercial doors for a project?
The contractor, architect, property manager, door supplier, security contractor, and electrical team may all need input. Their involvement depends on the opening. Early coordination helps align wall construction, hardware, access control, accessibility, fire ratings, scheduling, and future maintenance requirements clearly.
Can an existing commercial door frame be reused during renovation?
An existing frame may be reused if it is square, secure, undamaged, sized, and compatible with the new door and hardware. Fire labels, anchors, corrosion, wall construction, floor height, and previous modifications should be inspected before the decision is finalized.
Should every storefront entrance use the same door and hardware?
Repeated storefront openings may look similar, but traffic, exposure, accessibility, security, and operating hours can differ. Hardware should reflect each location’s use. Standardizing components can simplify maintenance, although identical specifications are not always appropriate for every entrance within the property.
How should automatic door power requirements be planned?
Automatic door power should be coordinated before walls and ceilings are closed. The project team must confirm operator voltage, wiring routes, activation devices, safety sensors, emergency operation, access control connections, and electrical capacity. Structural support may also need early preparation.
What should be included in a commercial door project budget?
The budget should cover doors, frames, glazing, hardware, access control, automatic operators, finishes, delivery, removal, installation, disposal, electrical work, security integration, and surrounding repairs. Allowances may also be needed for temporary access, phasing, permits, inspections, and unexpected concealed site conditions.
Sizing is a large part of that decision. Our guide to standard commercial door sizes breaks down the widths, heights, thickness, and rough openings you will be working with before you order.
