Colour Coated Roofing Sheet Price in Chennai (2026 Updated Guide)

Colour Coated Roofing Sheet Price in Chennai (2026 Updated Guide)

Whether you’re building a warehouse, factory shed, commercial building, or home extension in Chennai, one of the first questions you’ll ask is

“What’s the colour coated roofing sheet price in Chennai in 2026?”
This guide breaks down how pricing works, what factors influence cost, typical price ranges you can expect, and how to make the right choice for your project.

Why Colour Coated Roofing Sheets Are Popular in Chennai

Chennai’s climate — hot sun, high humidity, coastal salt air, and heavy monsoon rains — is tough on roofs. Plain metal sheets rust quickly, and basic galvanized sheets often fall short.

That’s where colour coated roofing sheets (PPGL / pre-painted Galvalume) come in. They’re stronger, better at resisting corrosion, and reflect heat more effectively — which improves comfort and protects your building.

Before we look at pricing, let’s understand what affects it.

Key Factors That Affect Roofing Sheet Price in Chennai

1. Steel Thickness

Price increases with thickness. Thicker sheets are stronger and last longer, especially in industrial and coastal conditions.

Typical thicknesses used include:

  • 0.45 mm

  • 0.50 mm

  • 0.55 mm

  • 0.60 mm

In Chennai’s climate, 0.50–0.60 mm is often preferred for industrial and warehouse roofs.

2. Coating Type & Coating Weight

Colour coated sheets are not all the same. They differ by:

  • Al-Zn coating weight (gsm)

  • Paint layer thickness (microns)

Higher coating weight and stronger paint systems = better corrosion resistance = higher price.

3. Profile Type

Profiles include:

  • Trapezoidal

  • Corrugated

  • Tile profile

Deep trapezoidal profiles usually cost more because of manufacturing complexity and better structural performance.

4. Length & Customization

Standard lengths are cheaper. If you need custom lengths to reduce wastage, that increases cost slightly but saves overall material wastage.

5. Quantity Ordered

Bulk orders for large sheds or factories get better pricing per sheet than small, single-site orders.

6. Accessibility & Delivery

Local supply in Chennai reduces transport cost. If your site is in a remote part of Tamil Nadu, delivery fees may increase.

Updated Price Range – Colour Coated Roofing Sheet Price in Chennai (2026)

Note: The ranges below are estimates based on Chennai market conditions, manufacturer quotations, and current raw material price trends.

Thickness (mm)Colour Coated Roofing Sheet Price in Chennai per Sq. Ft (2026 Estimate)
0.45 mm₹30 – ₹35
0.47 mm₹35 – ₹45
0.50 mm₹45 – ₹50
0.60 mm₹50 – ₹70

📌 These prices are approximate retail prices and can vary based on:

  • Manufacturer brand

  • Coating type

  • Profile depth

  • Quantity purchased

  • Delivery location within Chennai

Typical Price Variations Explained

WP (Wide Profile) vs Normal Profile

Wide profile sheets may cost slightly more because they cover larger area with fewer joints.

Paint System

Premium paint systems (PVDF, SMP) command higher prices than basic polyester paints.

Coastal Areas

Battched shipments meant for coastal industrial zones (Ennore, North Chennai) may include higher coating specs — slightly higher price but better corrosion resistance.

How to Calculate Your Roofing Sheet Cost for Chennai Projects

Here’s a simple way to estimate:

  1. Measure roof area in sq. ft.

  2. Decide thickness based on usage:
    Warehouse/Factory → 0.50–0.60 mm
    Commercial / Residential → 0.45–0.50 mm

  3. Multiply area × price per sq. ft

  4. Add installation cost (fasteners, labour, sealants)

  5. Add delivery charges (if applicable)

Example:
If your roof area is 10,000 sq. ft and you choose 0.55 mm panels at ₹70 per sq. ft:

10,000 × ₹70 = ₹700,000

  • Installation & delivery = depends on site conditions

Where to Buy – Choosing the Right Supplier in Chennai

When hunting for the best price, remember these tips:

1. Don’t Buy Based on Price Alone

Cheaper sheets without proper coating or lower thickness fail faster in Chennai’s climate.

2. Ask for Material Test Certificates

Verify:

  • Coating weight (gsm)

  • Paint thickness (microns)

  • Material grade and manufacturer source

3. Compare Multiple Quotes

Get at least 2–3 quotes from established manufacturers or authorised dealers.

4. Check Recent Projects

Experience in Chennai industrial sheds, warehouses, or commercial buildings is a good sign.

Installation Cost & Components to Remember

Price of roofing sheets is only one part of the total roof cost. Add:

  • Fasteners & washers (coated)

  • Ridge and flashing materials

  • Sealants and weather strips

  • Labour charges

In Chennai, installation cost is typically 15–25% of roofing material cost, depending on project complexity.

Benefits That Make the Price Worth It

Even if colour coated sheets cost a bit more than basic sheets, here’s why they are worth it in Chennai:

1. Heat Reflection Saves Power

A cooler roof means less heat transfer inside — lower fan/AC load, lower power bills.

2. Corrosion Resistance

Better Al-Zn coating and paint systems fight Chennai’s humidity and salt air.

3. Longer Life

Better finish and coating = less repainting and maintenance.

4. Improved Aesthetics

Available in multiple colours — good for showrooms, commercial spaces, and home extensions.

In a Nutshell

The colour coated roofing sheet price in Chennai varies based on thickness, coating quality, profile type, quantity, and delivery location. In 2026, prices typically range from ₹30 to ₹70 per sq. ft, depending on the specifications you choose.

But more importantly, good roofing is an investment — not just a purchase. If you choose the right thickness, coating system and supplier, your roof will perform better, last longer, and cost you less in maintenance over time.

Frequently Asked Questions

PPGL roofing sheet price in Chennai depends on thickness and coating weight. Most PPGL sheets fall within the range of ₹35 to ₹60 per sq. ft for industrial-grade quality.

For warehouses, factories, and industrial sheds, 0.50 mm to 0.60 mm thickness is commonly recommended. For heavy-duty roofing or long-span sheds, 0.55 mm and above is preferred.

Roofing sheet prices vary based on:

  • steel grade

  • thickness accuracy

  • coating gsm (Al-Zn coating weight)

  • paint quality (microns)

  • warranty terms

  • manufacturer vs trader supply

To calculate cost:

  1. Measure roof area in sq. ft

  2. Choose thickness and profile

  3. Multiply area × price per sq. ft

  4. Add installation cost, fasteners, ridge flashing, and delivery charges

Not always. Chennai’s humidity and coastal conditions can cause low-quality sheets to rust faster. It is better to choose a sheet with proper coating thickness and verified quality rather than only choosing the lowest price.

Coating gsm refers to the amount of zinc or Al-Zn coating applied on the steel sheet. Higher gsm means better corrosion resistance and longer lifespan, which increases the price.

Light colours like off-white, light grey, beige, and sky blue are best because they reflect sunlight and reduce indoor heat compared to darker colours.

Usually no. Roofing sheet price covers only material. Installation costs are separate and include labour, fasteners, sealants, ridge caps, flashing, and other accessories.

A good quality colour coated roofing sheet can last 15 to 25 years, depending on coating quality, thickness, installation method, and maintenance.

For warehouses and industrial sheds, trapezoidal profile sheets are preferred because they offer better strength, load handling, and water drainage compared to standard corrugated profiles.

To avoid low-quality material, always ask for:

  • Material Test Certificate (MTC)

  • coating gsm details

  • paint thickness details

  • warranty document

  • thickness verification using a gauge
