Decra steel roof tiles have many significant advantages over plastic roof tiles

Decra Lightweight Roofing Tiles a better alternative to plastic roof tiles Decra offers a choice of six lightweight roof tile profiles, available in a wide range of colours. Decra® roofing tiles are designed to provide an attractive and economic finish for all types of roof down to 10° pitch. The lightweight roofing system comprises coated, galvanised steel tile panels with the appearance of traditional roof tiles. Read more about a better alternative to plastic tiles, view the Decra range of roof tiles

Unlike plastic roof tiles, Decra tiles have a core of zinc aluminium galvanised steel, which is further protected with a unique multi-layered coating system. The granular surface is ceramically glazed at high temperature for exceptional long term colour stability.
This construction provides an outstandingly strong tile, which is as light or lighter than plastic roof tiles, weighing approximately 85% less than concrete tiles.

Advantages over plastic roof tiles

• Plastic roof tiles can be vulnerable to atmospheric temperature change. All plastics are designed to perform within designated temperature ranges for the type of grade of plastic selected. If the weather is to hot, then the moulded shape of the plastic may be deformed by the heat. If the weather is to cold then there may be a potential for the plastic roof tiles substrate to become brittle and easily cracked and damaged.
• Steel has a low coefficient of expansion when exposed to hot sunshine, some grades of plastic can significantly expand in heat, potentially imposing unwanted stresses on the top surface coatings applied to them, this can in some case lead to the surface coatings becoming brittle and cracking.
• Quality of recycling - Steel can be infinitely recycled and because it is so widely used a material, the ranges of possible uses for it are endless, a recycled Decra tile in its next life could be a tin can, car or a surgical instrument . Plastic can also be recyled at the end of its life, but due to the almost infinite range of different plastisisers added to plastic during manufacture, the recyling ability may be limited to low grade products.
• Decra tiles are both stronger and lighter, but unlike plastic roof tiles their strength can never effected UV degradation.
• Decra Tiles are more compact, although each tile is of a similar weight to plastic roof tiles, Decra tiles steel strength advantage allows them to be manufactured from steel that is typically 0.45mm thick, typically less than one-fifth the thickness of plastic roof tiles, as a consequence each pallet of plastic roof tiles covers a far smaller roof area than Decra roof tiles.
