METAL ROOFING SHEETS
Metal roofing sheets are eco-friendly roofing solutions, as they can be recycled. Generally, they are made of tin, zinc, aluminium and copper. Metal roof sheets are similar to corrugated roofing sheets in terms of the composition but they have fewer curves. You will find numerous styles, textures and colours in this class of roofing sheets and can make a choice between contemporary or traditional designs for your home.
Advantages:
Our roofing sheets are easy to install and can be customised for building rooftops, depending on factors like durability, price, energy efficiency and longevity. Roofing panels made of metal can withstand extreme weather conditions like heavy rains, snow and even fire. They are also pest-resistant and are preferred, owing to their longevity and durability. Metal roofs are excellent insulators and are widely used in garden buildings, garages, backyards, household cladding and industrial roofs.
