Overview
Commercial ribbed steel garage doors, also known as pan doors, are heavy-duty sectional overhead doors constructed from single-skin galvanized steel panels reinforced with deep vertical ribs. Designed for high-demand warehouses, agricultural facilities, and loading docks, these doors are available in 20, 24, or 25-gauge steel, offering uninsulated open-back security or vinyl-backed polystyrene insulation options for climate control.
Features & Benefits
Commercial Ribbed Steel Garage Doors feature a variety of commercial standard ribbed, flush, and embossed patterns including stucco and woodgrain finishes. Available in multiple steel gauges for varying duty requirements, these commercial overhead doors provide a cost-effective solution for warehouses, distribution centers, loading docks, agricultural facilities, and industrial buildings.
These pan-constructed overhead doors excel in demanding environments and are available in both insulated and non-insulated configurations, offering flexibility for facilities with different performance and energy efficiency requirements.
Steel Gauge & Duty Selection Guide
Selecting the appropriate steel gauge is one of the most important factors when choosing a commercial ribbed steel overhead door. Steel gauge directly impacts durability, impact resistance, and long-term performance.
20-Gauge Ribbed Steel
- Maximum impact resistance
- Ideal for heavy industrial facilities
- Recommended for freight terminals, loading docks, and high-wind environments
- Best choice for facilities with frequent forklift traffic
24-Gauge Ribbed Steel
- Standard commercial-duty construction
- Excellent balance of durability and value
- Commonly used in warehouses, distribution facilities, and agricultural buildings
25-Gauge Ribbed Steel
- Economical commercial solution
- Suitable for lighter-duty commercial applications
- Ideal for facilities with lower traffic and reduced impact exposure

Insulation Options & R-Values
Commercial ribbed steel garage doors are available in insulated and non-insulated configurations to meet a variety of performance and budget requirements.
Open-Back (Non-Insulated) Doors
Open-back pan doors provide economical security and durability for facilities where thermal performance is not a primary concern. These models are commonly chosen for warehouses, agricultural buildings, and applications in climate-controlled environments.
Vinyl-Backed Polystyrene Insulation
Insulated models utilize 1-1/2-inch polystyrene insulation combined with a vinyl backing system to improve energy efficiency and reduce heat transfer. Available models provide R-values up to 10.25, helping facilities improve thermal performance and indoor comfort.
Steel-Backed Insulated Construction
For applications requiring a more finished interior appearance and additional panel rigidity, steel-backed insulated models provide a three-layer construction consisting of steel exterior, polystyrene insulation core, and steel interior backing.
