Colour Coated Steel

Colour coated steel refers to galvanised or galvalume steel pre-painted with high-performance coatings. This combination of structural resilience and aesthetic flexibility makes it a preferred material for modern construction—used extensively in roofing, cladding, partitions, and façades. With reliable corrosion resistance and long-lasting finishes, colour coated steel is well suited to industrial, commercial and residential applications.

At JSW One MSME, we offer an extensive selection of colour coated steel sheets in a variety of profiles, thicknesses and shades. Every product meets stringent Indian Standards, ensuring both performance and compliance.

FAQs

What is the difference between PPGI and PPGL sheets?
PPGI (Pre-Painted Galvanised Iron) sheets are made from zinc-coated steel, offering standard corrosion resistance. PPGL (Pre-Painted Galvalume) sheets use an aluminium-zinc alloy base, providing superior protection in saline or industrial environments.
How long do colour coated steel sheets typically last?
With proper maintenance, PPGI sheets can last 15–20 years, while PPGL sheets may last 25–30 years, depending on environmental conditions and coating type.
Are colour coated sheets suitable for coastal areas?
Yes. PPGL sheets, in particular, are recommended for coastal regions due to their enhanced resistance to salt spray and humidity.
Can I customise the colour and finish of the sheets?
Absolutely. JSW One MSME offers a range of colours and finishes, including glossy, matte, and textured options, to match specific architectural requirements.
What profiles are available for colour coated sheets?
Common profiles include corrugated, trapezoidal, tile, and standing seam. Custom profiles can also be produced based on project needs.
Do these sheets contribute to energy efficiency?
Yes. The reflective coatings on colour coated sheets can reduce heat absorption, leading to lower indoor temperatures and reduced cooling costs.
How should I maintain colour coated steel sheets?
Regular cleaning with mild detergents and water, avoiding abrasive tools, helps maintain their appearance and longevity.
Are these sheets environmentally friendly?
Yes. Colour coated steel sheets are recyclable and align with green building practices, contributing to sustainable construction.
Can they be used for both roofing and wall cladding?
Certainly. Their versatility makes them suitable for various applications, including roofing, wall cladding, partitions, and façades.
What is the typical thickness range available?
JSW One MSME offers sheets ranging from 0.3 mm to 1.2 mm in thickness, catering to diverse structural requirements.
Are accessories like flashings and fasteners provided?
Yes. We supply matching accessories to ensure seamless installation and aesthetic consistency.
How do colour coated sheets perform under extreme weather conditions?
They are designed to withstand various climatic conditions, including heavy rainfall, strong winds, and high temperatures, without compromising structural integrity.
Is there a difference in performance between glossy and matte finishes?
While both finishes offer similar protective qualities, matte finishes may better conceal minor surface imperfections and are preferred for certain aesthetic applications.
Can these sheets be used in pre-engineered buildings (PEBs)?
Yes. Their lightweight nature and ease of installation make them ideal for PEBs, enhancing construction efficiency.
What standards do JSW One MSME's colour coated sheets comply with?
Our products adhere to Indian Standards such as IS 15965 and IS 14246, ensuring quality and performance consistency.
