Polycarbonate Sheets for Railway Station Roofing — CPWD & RLDA Approved
Railway stations are among India's most demanding roofing environments. High passenger movement, extreme weather, structural span requirements, and strict safety regulations make material selection a critical engineering decision.
Roofing Requirements in Railway Infrastructure
For PWD, CPWD, and RLDA projects, roofing material is not just about coverage — it must meet structural, thermal, fire, and durability performance standards:
- High wind load resistance
- Impact resistance against debris and vandalism
- UV protection for passenger comfort
- Fire-performance documentation available on request
- Long-span structural capability
- Low-maintenance outdoor performance
- Daylighting efficiency to reduce operating costs
Traditional roofing systems — metal sheets and glass — often fail to provide a balanced combination of these requirements. Polycarbonate does.
Thermal Performance — U-Value Comparison
U-value measures heat transfer through a material. Lower U-value = better thermal insulation. Thermal performance is critical in semi-enclosed railway structures.
For railway platform canopy roofing, 16 mm multiwall provides a strong balance of structural rigidity and thermal insulation.

Technical Specifications for Tender Compliance
When specifying polycarbonate sheets for railway station roofing in CPWD / RLDA tenders, include:
- Thickness: 10 mm / 16 mm / 25 mm (multiwall)
- UV co-extruded protection layer on both faces
- Light transmission percentage (by tint)
- U-value performance (tested, not calculated)
- Fire documentation: Available on request after product confirmation
- Wind load resistance certification
- Impact test compliance
- Warranty: 10 years against manufacturing defects, subject to standard terms
Applications in Railway & Metro Infrastructure
- Railway platform canopies and covered waiting areas
- Foot over bridge (FOB) roofing
- Metro station concourse and entrance canopies
- Bus rapid transit shelters
- Pedestrian subway lighting panels
- Ticketing counters and public area covers
Coxwell has supplied polycarbonate systems to Indian airports, metro stations, and CPWD projects. Our team can provide tender-ready specifications, U-value data sheets, and structural recommendations.
