There is no need to make a choice based on appearance alone. When ordering metal roofing , you need to pay attention to much more important parameters. They determine the durability of the roof.
metal tile owes its popularity to a large extent to its low price. When choosing, you should not, however, choose the cheapest product from an unknown manufacturer. The resistance of such a material to fading, corrosion and, as a result, the service life can be significantly reduced. Let's consider what to look for when choosing and buying metal tiles.
- First: high quality core
For the quality of the metal tile, and therefore its durability, the most important thing is the steel core. Various grades of steel are used for its production. It is better if the steel comes from the company's own factories. This makes it possible to trace all stages of the production process from the very beginning and, as a result, offer quality material.
- Second: sheet thickness
Even the best quality steel sheet must be of the correct thickness specified in the applicable standards. There must be additional protection against corrosion; for this, a double-sided zinc coating is applied to the core. Its smallest weight should be 275 g /m2. With this amount of zinc, there is no need to be afraid of the risk of corrosion in places where the roofing sheet is cut.
- Third: protective layers
The metal tile is protected by additional layers. They give it color, shine and texture, increase its resistance to corrosion under the influence of external conditions, mechanical damage (scratches) and the harmful effects of UV rays.
- Fourth: guarantee
Before buying metal tiles, you should carefully read the terms of the warranty. It is necessary to pay attention not only to the period of its validity, but also to what it guarantees (it concerns the perforation of the plate or only the durability of the coating).
