What Are Profile PPGI Sheets?

Profile PPGI Sheets are profiled roofing or cladding sheets made from pre-painted galvanized steel.

PPGI stands for Pre-Painted Galvanized Iron/Steel. The steel substrate has a metallic zinc coating and is then coated with paint to provide colour, appearance and additional protection.

The material is formed into profiles such as corrugated, trapezoidal or ribbed shapes for roofing and cladding applications.

The Bureau of Indian Standards’ IS 14246:2024 specifically allows continuously pre-painted galvanized steel sheets to be supplied in profiles, with profile dimensions and tolerances agreed between the purchaser and manufacturer.

For contractors, builders and fabricators, the important specifications are:

  • Base steel thickness
  • Overall sheet width
  • Effective/cover width
  • Sheet length
  • Profile design
  • Zinc coating
  • Paint coating
  • Colour and finish
  • Grade
  • Quantity
  • Brand or mill

Important: A PPGI roofing sheet should not be selected only by colour or price. Thickness, coating and profile are equally important.


How Are Profile PPGI Sheets Made?

PPGI starts with galvanized steel.

The galvanized steel substrate is coated with a paint system and then formed into the required profile.

The result is a steel sheet that combines the metallic coating of galvanized steel with a coloured organic coating.

The simplified process is:

  1. Steel substrate preparation
  2. Galvanizing with zinc
  3. Surface treatment
  4. Primer application
  5. Paint/top coating
  6. Curing
  7. Profiling/forming
  8. Cutting to required length
  9. Inspection and packing

The exact coating system and manufacturing process can vary between products and manufacturers.

How PPGI Roofing Sheets Are Made

Types of Profile PPGI Sheets

Profile PPGI sheets are available in different shapes and configurations.

The right profile depends on the roofing design, span, appearance, drainage requirement and structural design.

1. Corrugated PPGI Sheets

Corrugated sheets have repeated curved or wave-like ribs.

They are commonly used for:

  • Sheds
  • Farm buildings
  • Warehouses
  • Small commercial structures
  • Wall cladding

2. Trapezoidal PPGI Sheets

Trapezoidal profiles have angular ribs rather than rounded corrugations.

They are widely used for roofing and wall cladding where a more structured profile is required.

3. Ribbed PPGI Sheets

Ribbed sheets use raised longitudinal ribs.

The ribs provide the sheet with its profiled form and can contribute to stiffness.

4. Tile Profile PPGI Sheets

Tile-profile sheets are formed to resemble traditional tiled roofing.

They can be useful when the project requires a more decorative roof appearance while using a lightweight steel roofing material.

5. Special / Custom Profiles

Manufacturers may offer other profiles depending on the production line and project requirement.

JSW’s colour-coated product information lists profiles including corrugated, trapezoidal, ribbed, Mangalore tile, wave and arch-trapezoidal profiles.

In the market, buyers commonly specify sheets by:

  • Thickness
  • Overall width
  • Effective cover width
  • Length
  • Profile height
  • Number of sheets required

PPGI Sheet Thickness Chart

ThicknessTypical Use Consideration
0.30 mmLight-duty roofing where suitable

0.45 mmMore demanding roofing applications
0.50 mmStronger roofing/cladding requirements
0.60 mmHeavy-duty or higher-performance applications
0.80 mm+Special/project-specific requirements

Note: These are practical market categories, not a universal classification. The suitable thickness depends on span, support spacing, wind/load requirements, profile geometry and manufacturer’s specification.

JSW’s PPGI coil specification lists a much broader substrate thickness range of 0.18–1.5 mm, demonstrating that PPGI products are not limited to the commonly stocked roofing thicknesses.

Common PPGI Sheet Lengths

Profile sheets can be cut to length depending on the manufacturer’s equipment and project requirement.

Common project enquiries may include lengths such as:

  • 6 ft
  • 8 ft
  • 10 ft
  • 12 ft
  • 14 ft
  • 16 ft
  • 18 ft
  • 20 ft

These should be treated as market examples, not a fixed standard range.

For large roofing projects, ordering sheets to the required roof slope length can reduce unnecessary joints and overlaps.

PPGI Sheet Sizes & Thickness Guide

PPGI Sheet Width: Overall Width vs Effective Width

This is an important point that many first-time buyers miss.

A profiled sheet has an overall width, but after overlapping adjacent sheets, the usable effective cover width can be smaller.

For example, a supplier might quote a sheet by its overall width while the contractor calculates the roof area using effective coverage.

Therefore, always ask:

“What is the effective cover width after overlap?”

This gives you a more accurate estimate of the number of sheets required.


PPGI Sheet Weight Calculation

PPGI sheets are often purchased on a per-kg basis, while roofing requirements are calculated by area.

That makes weight calculation useful for contractors and fabricators.

For a simplified steel calculation:

Weight ≈ Length × Width × Thickness × 7.85

Where:

  • Length = metres
  • Width = metres
  • Thickness = millimetres
  • 7.85 = approximate steel density factor

Example

Suppose a flat-equivalent sheet is:

  • Length = 3.66 m
  • Width = 1.0 m
  • Thickness = 0.45 mm

Estimated steel weight:

3.66 × 1.0 × 0.45 × 7.85 ≈ 12.9 kg

For a profiled sheet, actual weight and coverage should be checked against the manufacturer’s specifications because profile geometry, dimensions and coating affect the supplied product.

Tip for fabricators: For billing and project costing, use the supplier’s actual declared or weighed mass rather than relying only on a theoretical calculation.


Common Uses of Profile PPGI Sheets

PPGI profile sheets are used in many roofing and cladding applications.

Industrial Sheds

PPGI roofing is commonly considered for:

  • Factories
  • Workshops
  • Warehouses
  • Storage sheds
  • Industrial buildings

Commercial Buildings

They can be used for:

  • Shops
  • Commercial sheds
  • Service centres
  • Market structures
  • Small business premises

Agricultural Structures

Profiled colour-coated steel can also be used for:

  • Farm sheds

Benefits of Profile PPGI Sheets

1. Attractive Appearance

PPGI sheets are available in different colours and finishes.

This gives builders more options than plain galvanized roofing.

2. Corrosion Protection

The galvanized substrate provides zinc-based corrosion protection, while the paint system provides an additional protective layer.

The actual durability depends on the coating system, environment, thickness and maintenance.

3. Lightweight Roofing Solution

Steel roofing sheets can provide a large roof coverage area without the mass associated with many conventional roofing materials.

This can make transportation and installation easier.

4. Easy to Handle

Profile sheets can be manufactured in project-specific lengths, which can simplify handling and installation.

5. Suitable for Roofing and Cladding

The same basic PPGI material can be used in different profiles for roofs, walls and architectural applications.

6. Consistent Factory-Applied Finish

Unlike painting steel after installation, PPGI receives its coating under controlled manufacturing conditions.

Tata Steel notes that pre-coated colour sheets provide uniformity and performance advantages compared with post-coated products.

PPGI vs GI vs PPGL: What's the Difference?

PPGI Profile Sheet Price Per Kg in India

One of the most common searches from buyers is:

“PPGI profile sheet price per kg”

There is no single fixed price because PPGI sheets are sold in different thicknesses, coating specifications, profiles, brands and colours.

As a current market reference, Tata Nexarc reported indicative August 2026 PPGI roofing prices of approximately ₹65–₹108 per sq ft, depending on thickness, coating and brand.

Indicative PPGI Price Guide

Product / Market ReferenceIndicative Price
PPGI roofing market reference₹65–₹108/sq ft
Example supplier listing₹85/kg
Final project priceQuote-based

Important: These are indicative references only. Your actual PPGI sheet price can change according to thickness, profile, brand, colour, coating, quantity, GST, freight and location.

For a project in Jaipur, the delivered rate can also differ from a factory or Delhi-market quotation because transportation and supply conditions are different.


Why PPGI Price Per Kg and Per Sq Ft Can Look Different

This causes confusion for many customers.

A supplier may quote:

₹/kg

while another supplier may quote:

₹/sq ft

Both can be valid pricing methods.

The relationship depends on:

  • Thickness
  • Steel density
  • Sheet width
  • Profile
  • Coating
  • Weight
  • Effective coverage

Example

A thicker sheet generally contains more steel per square metre.

Therefore, comparing two PPGI sheets only by their per-sheet price can be misleading.

For a proper comparison, check:

Thickness + coating + effective coverage + weight + brand + final delivered price.


Factors Affecting PPGI Sheet Price

1. Thickness

Thickness is one of the most important price and weight factors.

A 0.50 mm sheet and a 0.35 mm sheet should not be compared purely on price.

2. Zinc Coating

The metallic coating specification affects product performance and cost.

3. Paint System

Different paint systems, coating thicknesses, colours and finishes can affect the final price.

4. Brand

Branded material can carry a premium because of product consistency, certification, coating specifications and distribution.

5. Profile

Different profiles require different forming processes and may have different coverage and material requirements.

6. Quantity

A bulk project order can receive a different commercial rate from a small retail requirement.

7. Sheet Length

Custom cut-to-length requirements can influence handling, production and transportation costs.

8. Freight and GST

The final delivered price should account for applicable taxes and transportation.

Buying Tip: Ask for a complete quote rather than comparing only the basic ₹/kg number.


How to Choose the Right PPGI Profile Sheet

Step 1: Determine the Application

First decide whether the sheet is required for:

  • Roofing
  • Wall cladding
  • Shed construction
  • Warehouse
  • Farm structure
  • Residential extension
  • Commercial building

Step 2: Check Structural Requirements

The required thickness and profile should be selected according to the structural design.

For roof applications, the supporting structure, span, purlin spacing, wind conditions and imposed loads matter.

BIS notes that profiled PPGI sheets supplied for structural applications should meet the relevant imposed-load conditions specified with reference to IS 875 Part 2.
Source: BIS — IS 14246:2024 Product Manual

Step 3: Choose Thickness

Do not choose thickness only because it is cheaper.

The correct thickness depends on the project requirements.

Step 4: Select the Profile

Choose corrugated, trapezoidal, ribbed, tile or another suitable profile according to the roof design.

Step 5: Confirm Effective Width

Always ask for the effective cover width after overlap.

Step 6: Compare Complete Quotes

Compare:

  • Thickness
  • Grade
  • Coating
  • Paint system
  • Profile
  • Effective width
  • Length
  • Brand
  • GST
  • Freight

This gives a much more meaningful price comparison.


PPGI Roofing Sheet Buying Checklist

Real-Life Example for a Fabricator

Hypothetical example:

A fabricator receives a requirement for a colour-coated roof for a workshop.

Instead of simply asking:

“PPGI sheet ka rate kya hai?”

the fabricator should provide:

  • Required thickness
  • Profile
  • Approximate roof area
  • Required sheet length
  • Preferred colour
  • Quantity
  • Delivery location

For example:

“Need 0.45 mm PPGI trapezoidal roofing sheets, approximately 12 ft length, required for a workshop roof. Please quote material and delivery.”

This gives the supplier enough information to prepare a more useful quotation.
