Metallic Tile Roof

Metallic tile – is one a relatively new roofing materials.

Metallic tile – is a material which ideally combines beautiful pattern, high aesthetic, durability of the metal, ecological and fireproof safety, wide colourer spectre, lightness of the material ( from 4.5 kg per square metre) and simplicity of assembling.     

For metallic tile production one uses high quality raw materials which are getting supplied from Slovakia, Korea, Taiwan, England and Germany.

For metallic tile profiling is been used zinc-coated sheet 0.5 mm thick with decorative polymer coating 25 micron thick.  Only high quality sheets is being used for metallic tile production. Coating types are: polyester, mat polyester, neomat, prelaq. The warranty for the metallic tile roof coating is 10 years. Lifetime for the metallic tile roof is 50 years.

All raw materials have been certified by international and Australian quality standards. Therefore the final product is completely responds to the Australian and European qualities requirements.

The steel sheet coating structure for the production of metallic tile:

 

The metallic tile sheet width is 1180 mm (or 1100mm considering overlapping). The width is a standard mazement.  The length of metallic tile sheet can vary from 600mm to 8000mm; any size in this limit is available.

Thus, sheets of metal are made on the size of the customer, which ensures a minimum number of joints on the roof. Excellent geometry for accurate product docking sheets of metal together during installation, which significantly reduces the time of the roofing work and guarantee superb quality.

 Metallic tile profiles

Slab of  metallic tile roof used for roofing in wide variety of buildings. Each type of metallic tile roof plates can have different combinations of the coating and color tone. Metal roofing panels are available in sizes specified by the client during the order (length equals the length of slabs of the roof). Light weight metal plate easy to install, they are also suitable for repairing old roofs.

 

  Effective width of metallic tile roof sheet: 1100 mm
The thickness of sheet: 0.5 mm
Max. length of the sheet: 8 m
Min. length of the sheet: 0.6 m
The height of the sheet: 39 mm

Types of metallic tile roof coatings

 

Brushed polyester (PEMA)

PEMA  is a polyester coating with good colour stability. This type of coating maintains its qualities over a wide range of climatic conditions, has excellent corrosion and mechanical stability.

Polyester (PE)

Polyester coating is used for internal and external surfaces of building structures. Polyester is a standard coating of roofing and walling profiles.

Qualities of metal

On the scope and durability of metallic tile coatings in different atmospheric conditions are influenced by many factors: the thickness of the coating, the type of paint application impurities (pigments, stabilizers). The coating thickness affects mainly on the mechanical properties: formability, abrasion and corrosion resistance, resistance to mechanical damage. Thicker coating withstands mechanical loads better than fine one. With a very thick coating (plastisol), there is still a risk of so-called precipitous corrosion, which can interfere with touch-up by the cut edges of roofing sheets after their installation.

Resistant to UV radiation

Temperature resistance and resistance to UV radiation for different coverages are quite different. The best performance in these categories has a coating PVDF -under UV radiation of its luster almost unchanged. Very persistent in the ultraviolet and pural cover and polyester and plastisol under sunlight fade.

Resistant to dirt
PVDF coating is perfectly carries the impact of sulphur dioxide and other air pollutants. But polyester and plastisol is easily contaminated by the presence in the air a significant amount of impurities.

Corrosion resistance
Corrosion resistance of coatings of metallic tile deteriorates when they are in the process of manufacture, transport or get damaged installation. When assembling materials with similar coating should focus on the treatment of sheet metal to avoid scratching them. Over time, scratched metal corrosion begins. In order to discourage corrosion of metal damaged areas immediately after installation to cover the repair with paint.
