Ribbed Metal Sheets

 

Roofing made of flat tin plates can be installed on any, even the most complicated roof shape, on domes and towers. Tin roofs are very durable, quickly and easily draining rainwater. They conduct heat well, so condensate forms on the surface of the tin from the underside due to the temperature difference. This creates corrosion of the tin and rotting of the wooden substrate, which is why it is obligatory to lay roofing foil. Tin roofs are noisy, so we need to install sound insulation as well. For roof covering, the most commonly used materials are tinplate, then zinc, copper, and aluminum plates in the form of flat, corrugated, and ribbed plates.

Roof slope:

  • Flat tin 6 – 300
  • Corrugated and ribbed tin 12 - 350
 
Roofs made of ribbed tin plates are used as elements for roof covering, facade construction, and partition walls, especially in industrial buildings. Ribbed plates are made from aluminum or steel sheet, double-sided plasticized. Steel plates can be tin-plated on one side. Tin ribbed plates are large-dimensional elements, so they can be quickly and easily installed. They are often used for roofs with lattice or similar carriers. The thickness of the tin is 0.6 – 1 mm, the useful width of the plates is 70 -90 cm, and the length is up to 12 meters. Ribbed plates on roofs are used in three ways: as roofing coverings – plates with lower folds, plates with higher folds - are roof carriers over which thermal insulation and waterproofing are installed, sandwich construction - made of profiled tin, and thermal insulation in the middle

Depending on the type and thickness of the material, height and type of profile, as well as the loads on the roof, the spacing of the bearers is calculated. The plates are secured to them with screws. They are interconnected with rivets. For roofs with a gentle slope, it is good for the plates to have a full length to avoid transverse overlaps.
