Choose your Flat Roofing Sheets Finish

At Cardinal Steels, we understand that different projects require different finishes to meet specific aesthetic and functional needs. That’s why we offer a variety of flat steel sheet finishes to choose from, including:


Galvanised – Shiny yet reserved silver colour finish. Galvanised finishes provide excellent corrosion resistance, making them ideal for environments exposed to moisture and other corrosive elements. This finish ensures that your flat metal sheets remain rust-free and maintain their appearance over time. Available in 0.4mm up to 0.7mm thickness. No Guarantee available.


Polyester – A smooth, glossy finish. This option is perfect for those looking to add a touch of colour to their roofing while benefiting from the durability of metal. Available in 0.4mm up to 0.7mm thickness. Up to 15 years guarantee.


Plastisol – Another gloss finish but is ideal for corrosion and abrasion resistance. Plastisol coatings provide an extra layer of protection, offering superior resistance to weathering and physical damage. Available in 0.4mm up to 0.7mm thickness. Up to 25 years guarantee

Flat Metal Sheet Cladding

In addition to their use for roofing purposes, our flat steel sheets can also be used as cladding. Flat metal cladding offers exceptional aesthetic and functional benefits, making them useful for renovation and construction projects where keeping costs down is a priority.

Our metal sheets offer a clean, modern look which looks at home in a wide range of architectural designs. Meanwhile, the durability and weather-resistant properties of the flat sheet metal makes them an ideal choice for protecting underlying structures from environmental damage while also improving the building’s insulation capabilities.
