Product Overview
What Are Colour Coated Roofing Sheets?
Colour Coated Roofing Sheets are pre-painted, high-strength steel sheets designed for long-term roofing and cladding applications. At Namdev Infratech, these sheets are manufactured from premium galvanised steel (PPGI) or galvalume steel (PPGL) substrates and coated with multi-layer paint systems that deliver superior UV resistance, corrosion protection, and aesthetic versatility.
Key Properties
- UV Resistance: Specially formulated top coats prevent colour fading for decades.
- Corrosion Protection: Zinc or Alu-Zinc base coating shields against rust even in coastal and high-humidity environments.
- Thermal Insulation: PPGL sheets and Puff sandwich panels significantly reduce heat transfer into buildings.
- Lightweight: Low self-weight reduces structural load and speeds up installation.
- Custom Lengths: Cut-to-length service ensures zero wastage on site.

Frequently Asked Questions
Everything you need to know before buying colour coated roofing sheets from Namdev Infratech.
How long do Colour Coated Roofing Sheets last?
With proper installation and maintenance, colour coated roofing sheets can last 15–25 years depending on environmental conditions, coating quality, and the substrate selected (PPGI vs PPGL). PPGL sheets typically offer a longer service life in humid or coastal environments.
Are these sheets heat-resistant?
Yes. PPGL sheets provide excellent thermal insulation, reducing heat absorption into buildings. For maximum thermal performance, Puff Sheets (sandwich panels) with a 30 mm or 50 mm PUF core are the recommended choice for hot climates or temperature-sensitive applications.
Which coating is best for coastal areas?
PPGL (Pre-Painted Galvalume) sheets are ideal for coastal regions. The aluminium-zinc alloy coating (Galvalume) provides significantly higher resistance to salty air, humidity, and corrosive marine environments compared to standard PPGI sheets.
Can the sheets be customised in colour and size?
Yes. Namdev Infratech offers all variants in six standard colours — Blue, Brick Red, Off-White, Royal Blue, Grey, and Mist Green — with customisable lengths cut to your exact site requirements. Contact our team for custom colour enquiries on larger orders.
What thicknesses are available for Profile Sheets?
PPGI/PPGL Profile Sheets are available in five thickness options: 0.30 mm, 0.35 mm, 0.40 mm, 0.45 mm, and 0.50 mm. Thicker gauges are recommended for spans with higher structural loads or in regions with heavy wind or snow loads.
What are Puff Sheets and where are they used?
Puff Sheets are insulated sandwich panels comprising two pre-painted steel skins (PPGI or PPGL) bonded to a rigid polyurethane foam (PUF) core. They are widely used in cold storage facilities, clean rooms, food processing plants, and modern commercial buildings where both thermal and acoustic insulation are required alongside structural roof performance.
