The gas station canopy roof is the defining structural element — it sets the visual scale and determines what the station can accommodate in terms of vehicle height and volume. Material and system choice impacts construction cost, durability, and maintenance over the station’s lifetime. The Petrol Group team specifies canopy structures for fuel retail projects across 16 countries.
Roofing system comparison
Insulated sandwich panel: most common in new stations — two steel faces with EPS or PUR core. Excellent thermal insulation, clean finish, fast installation. Cost: BRL 1,800-2,500/m² installed. Life: 20-30 years. Trapezoidal sheet: lower cost, simpler installation, no insulation. Cost: BRL 1,200-1,800/m². Standing seam (ziplock): premium system with concealed fixings — superior visual result for upmarket stations. Cost: BRL 2,500-4,000/m².
Structural steel specification
Must be designed by a structural engineer per ABNT NBR 8681 and NBR 6123 (wind loads). Key parameters: regional wind speed zone, free span between columns (6-8m standard; 12m+ for truck clearance), snow load if applicable (Southern Brazil). Columns: galvanized carbon steel or painted with epoxy primer.
FAQ
How long does a metal canopy last?
With correct anti-corrosion maintenance (repainting every 8-12 years, annual anchor bolt check): 25-35 years for a properly specified steel structure.
