Features & Advantages



Strength of Steel : JSW Colouron Galvanised steel is manufactured using high quality hot metal made of most superior and environment friendly Corex technology.

It offers several grades including high tensile steel with yield strength of 550 mpa to meet the needs of various specifications.


Paint Technology : JSW Colouron Galvanised steel is available in a variety of paint systems like Regular Modified Polyester (RMP), Silicon Modified Polyester (SMP), Super Durable Polyester (SDP), Poly Vinyldened Fluoride (PVDF) etc. The base metal has the first layer of primer coating on both top and bottom surface.

This helps to have a superior adhesion with the paint system. The final paint coating provides additional protection to withstand harsh weather conditions. The superior coating technology resists cracking and peeling even during heavy forming operations, hence enhances life .


Corrosion Protection : Galvanized substrate is available in a wide zinc coating range (90 to 275 gsm)

Superior Coating Quality provides excellent corrosion protection in various climatic conditions, hence enhances life.


Additional Protection : A thin organic low-density polythene film (30-40 microns) coating.

It protects the sheet from transit and storage damage and lubricates the sheet surface during forming. This gives longer life & retention of appearance.


Formability & Aesthetics : Can be readily roll formed, bend, pressed, cut, drilled, lock seamed and stamped without sacrificing coating adhesion/ quality of paint.

Easy formability and bending property opens new horizons to the architect's creativity. The wide range of colours provides options to the architect to customize requirements.


Convenience : The light-weight high strength Steel.

They are Economical as they require lighter supporting structure and also reduces transportation costs. And they are virtually maintenance free .


Consistent Quality : Undergoes stringent Quality Control tests

Ensures excellent performance in all weather conditions and hence enjoys trust & confidence of millions.


Thermal efficiency :

JSW Colouron Roofing & Cladding results in less heat radiation compared to other commonly used roofing materials. JSW Colouron when combined with insulation makes a cost effective, energy efficient roofing system.


Environment friendly :

JSW colouron galvanised steel has a long life and if eventually replaced are recyclable without losing quality. The paint used to coat the base metal is also toxic free.
