Question 1

What makes a door a commercial door?

Accepted Answer

A commercial door is engineered for high-cycle use, code compliance, and the operational demands of business and institutional buildings — not residential homes. Commercial doors carry ratings for fire (ULC, NFPA 80), security (UL 437, CPNI), accessibility (CSA B651, ADA), and impact resistance. They use heavier-gauge steel (typically 16–14 gauge for hollow metal vs. 24 gauge residential), reinforced frames, industrial hardware (Grade 1 ANSI BHMA), and operators rated for thousands of daily cycles. Common categories: sectional overhead, rolling steel, automatic entrance, fire-rated, hollow metal, dock equipment, security shutters, and air curtains. The Ontario Building Code, NBC, and provincial fire codes specify which door type is required by occupancy class. Cycle ratings, climate zone, and AHJ requirements drive the final spec — we document each in writing on every CommercialDoors.ca quote. Across our 48-city Canadian network — Toronto, Montréal, Vancouver, Calgary, Edmonton — this answer holds. Province-specific variations (OBC, QBC, BCBC, ABC, NBC, Atlantic) only adjust the code reference numbers, not the engineering principle.

Question 2

What does a commercial door cost?

Accepted Answer

Commercial door cost depends heavily on category and specification. Typical Canadian installed price ranges (2026): hollow metal door + frame $1,200–$3,500; sectional overhead door (10x10 to 14x14) $2,800–$8,500; rolling steel door $3,500–$12,000; fire-rated assembly with hardware $2,500–$6,000; automatic sliding entrance with operators $8,000–$22,000; loading dock door + leveler + seal package $12,000–$28,000; high-speed roll-up door $14,000–$35,000; hangar bi-fold (50x14 small aircraft) $35,000–$95,000. Pricing variables include insulation R-value, wind/snow load engineering, opener horsepower and cycles, and hardware grade.

Province-specific code variations adjust only the citation numbers, not the engineering principle.

Question 3

What is the lifespan of a commercial door?

Accepted Answer

Lifespan depends on cycle count and maintenance. Hollow metal doors and frames: 25–40 years with periodic painting and hardware replacement. Sectional overhead doors: 15–25 years residential-grade, 20–30 years commercial-grade with annual lubrication. Rolling steel doors: 25–40 years (mechanical) or 100,000+ cycles (motorized) before drum/spring replacement. Automatic sliding doors: operator overhauls every 7–10 years, doors themselves 15–20 years. Fire-rated doors: indefinite physical lifespan but require annual NFPA 80 inspection and immediate hardware replacement when out of compliance. Dock levelers: 15–20 years depending on traffic volume and refurbishment cycles. The biggest lifespan multiplier is preventive maintenance — annual inspection plus bi-annual lubrication doubles useful life.

Question 4

How much does a 12x12 overhead door cost?

Accepted Answer

A 12x12 commercial overhead door installed in Canada typically costs $3,800–$7,500 for sectional steel (insulated), $4,500–$9,200 for full-view aluminum and glass, and $5,800–$12,000 for rolling steel. Pricing factors: insulation (R-12 standard, R-18 for cold storage), windload engineering (coastal BC and Atlantic Canada require higher-rated tracks), opener spec (1/2 HP standard, 1 HP for high-cycle), windows (added $400–$900), and electric strike or smart access integration. For warehouse and dock applications add a chain hoist or jackshaft operator. Installation labour typically $800–$1,800 per door including spring tensioning, track levelling, and operator commissioning. Get a written, all-in quote — beware of price-shopping on the door alone.

Question 5

What is the difference between a garage door and an overhead door?

Accepted Answer

The terms overlap but mean different things in commercial spec. "Garage door" colloquially refers to residential sectional doors (8x7, 9x7, 16x7) with light-gauge steel and standard residential springs. "Overhead door" is the trade umbrella for any door that opens upward into the ceiling space — including sectional, rolling steel, rolling sheet, and fabric high-speed. Commercial overhead doors carry heavier-gauge steel (24 ga residential vs 16-20 ga commercial), higher cycle springs (10,000+ vs 25,000+ cycles), industrial track and hardware, and are often custom-sized for warehouse and dock openings (12x12 to 30x20+). "Overhead Door" with capital letters is also a major brand owned by Sanwa Holdings — the original 1921 patent.
