Procuring heavy-duty commercial and residential doors across India requires a fine balance between long-term durability, structural aesthetics, and total lifecycle expenditure. While traditional solid wooden doors rot from subterranean termite attack and moisture, and hollow metal doors corrode in humid or acidic environments, Fiberglass Reinforced Polymer (FRP Doors) deliver a zero-maintenance, 100% waterproof, and chemical-resistant alternative.
In this technical pricing and architectural guide by Rawji Exports (kumar), we break down FRP door prices per square foot in India, examine structural core formulations (solid PUF vs honey-comb), evaluate standard architectural dimensions, and provide clear estimation benchmarks for project architects and procurement managers.
Key Price Summary (2026 Market Rates):
- Standard 30mm Hollow / Semi-Solid Core: ₹220 - ₹280 per sq. ft. (Ideal for residential bathrooms, toilets, and dry utility zones).
- Commercial 35mm High-Density PUF Core: ₹290 - ₹380 per sq. ft. (Ideal for hospitals, schools, commercial offices, and hotels).
- Industrial 40mm Solid Heavy-Duty Core: ₹390 - ₹520 per sq. ft. (Engineered for pharmaceutical cleanrooms, chemical plants, and heavy industrial facilities).
- Pre-Hung FRP Door Frame (Chaukhat 4"x2" to 5"x2.5"): ₹110 - ₹180 per linear foot.
1. FRP Doors Price Matrix by Thickness & Core Material
The total square foot cost of an FRP door is dictated by composite skin thickness, internal reinforcement framework, and core density:
| Door Thickness | Core Material | Approx. Price / Sq Ft | Recommended Application Area |
|---|---|---|---|
| 30 mm | Paper Honeycomb / Rigid Polymeric Ribs | ₹220 – ₹280 | Residential bathroom doors, toilet cubicles, internal residential rooms, staff washrooms. |
| 35 mm | High-Density PUF (40 kg/m³) | ₹290 – ₹380 | Hospital wards, educational institutes, IT office washrooms, coastal hotels & resorts. |
| 40 mm | Solid Marine Grade Composite Core + Steel Stiffeners | ₹390 – ₹520 | Pharma cleanrooms, chemical processing plants, fertilizer warehouses, coastal infrastructure. |
| 45 mm (Fire-Rated) | Intumescent Ceramic / Phenolic Core | ₹550 – ₹750 | Electrical sub-stations, boiler rooms, industrial fire exit stairwells (1 to 2-hour FR rating). |
2. Standard Architectural Sizes & Custom Fabrication
Rawji Exports manufactures standard metric and imperial door sizes, as well as customized dimensions tailored to exact site openings:
- Standard Bathroom / Toilet Sizes: 2.5 ft × 6.5 ft (750 × 2000 mm), 2.5 ft × 7.0 ft (750 × 2100 mm).
- Standard Bedroom & Office Room Sizes: 3.0 ft × 7.0 ft (900 × 2100 mm), 3.25 ft × 7.0 ft (1000 × 2100 mm).
- Hospital & Commercial Double Doors: 4.0 ft × 7.0 ft (1200 × 2100 mm), 5.0 ft × 7.0 ft (1500 × 2100 mm).
3. Key Cost Factors When Sourcing FRP Doors in India
When comparing vendor quotations, ensure you account for these technical variables:
- FRP Skin Thickness: Low-cost doors use flimsy 1.0mm skins. Rawji Exports engineers heavy-duty 2.0mm to 3.0mm monolithic skins reinforced with continuous glass fiber mats.
- Internal Hardware Reinforcements: Premium doors include embedded hardwood or steel backup plates at lock and hinge locations to prevent screw pull-out.
- UV-Resistant Gelcoat Finish: Exterior doors require isophthalic UV-stabilized gelcoat to prevent surface chalking and yellowing under intense Indian sunlight.
