Coated steel sheet products have many attributes that make them suitable for diverse use in construction industry. These colour coated steel sheets and coated wall panels provides a combination of strength formability, jointability, paintability and economy. Colour coated sheets provide excellent resistance to corrosion and hence has become the most preferred material for a wide range of construction uses, particularly roofing and walling.

Coated steel sheets makes a unique building material. These colour coated steel sheets combines the strength of steel with corrosion protection of zinc or zinc/aluminum alloy coatings. These colour coated sheets can be punched, pressed, roll-formed and joined into a number of structural and decorative building components.

Features

• Excellent design & secure fastening systems ensure the security and weather-light performance of coated steel roofing during extreme weather.
• Coated steel sheets are resistant to fire.
• Excellent thermal properties that keep the building cooler in summer and warmer in winter
• Prevents noise and provide quite roofing system, particularly when used in combination with appropriate insulation systems.

Crimped Sheet - (More uses than you could ever imagine)
Easy to install, crimped curved sheets provide versatility and creativity that bring new and refreshing design to industrial and domestic buildings. The combination curves and contours in concave and convex shapes with flats and angles can be used to add an aesthetic appeal to the building.

These sheets provides absolute design freedom with significant cost saving in construction. This is possible because:

• Crimped sheets require less supporting framework for parapets and roofs.
• Reduction or elimination of many flashing/cappings.
• Less cladding material required for covering a given curve.
