MODERN AND RELIABLE ROOFING of Metal

metal one the most commonly used material for roofing. It features lightweight, simple installation and affordable price. In Ukraine, this material is also used very successful and has excellent prospects.

Properties

metal favorably with low weight : roof of this material belongs to the category of the lungs. For example, metal weighs 5 kg/m ² , natural tile - 40 kg/m ² , bitumen - 15 kg/m ² , roofing materials - 5-12 kg/m ² . its second big plus is cost - for installation metal does not require a solid crate. Note, that metal:

1. elementary mounted
2. has a long Operating
3. not burn out on sun
4. not lose its properties in a wide temperature range (-50 to +120 ° C).

More One important characteristic - environmental safety.

disadvantage of metal can be noise during the rain and wind, but is subject to improper installation of the roof. This factor depends on the qualifications, experience erection organizations in this field. In the case of qualitative performance of works in gusts of wind did not knock metal, and when good install drainage noise flowing streams of water will not heard in the attic.

DATA SHEET
Based on European standards, the thickness steel sheet metal used for roofing, should not be less than 0.45 mm. For example tile company Ruukki produced sheets of 0.5 mm. In such settings metal roofing is easily installed and virtually no deformation. If Profiling more than a thin sheet (0.4 mm or less), especially when non-compliance technology in the field of bending thick steel can reach a critical point (Eg, around the mounting position may be deepening, which will collect water). Therefore, high-quality metal roofing thickness of 0,4 mm is used for decorative elements of the roof.
The steel sheet has a special coating, which must necessarily include passivating layer, the primer and coating. are the main passivating layer and primer. Without any of the ingredients , the basic polymer coating, will serve not more than 1-3 years. Note that polymer coating is also a decorative element. In order to understand whether all the layers, you need to consider in the context of the sample surface. Polymer coating can be 4 types.

Polyester:

• thickness of 22-27 microns (Depending on the manufacturer)
• advantage - low price.
• disadvantage - relatively low mechanical stability and durability of color
• lifetime - 1-10 years (depending on the manufacturer).
• is practically all manufacturers.

Brushed Polyester:

• thickness - 35 micron
• cost is higher than Conventional polyester,
• lasting color
• not shining in the sun (Only)
• visually most close to the natural tile
• guarantee of 15 years

Pura

• thickness - 50 micron
• high corrosion performance
• mechanical resistance
• color stability
• more expensive on average 20-30 % Higher than polyester
• lifetime of 10 years.

Plastisol (PVC 200)

• thickness - 200 micron
• the thickest and durable polymer coating
• of polyvinyl chloride (in some countries is considered environmentally harmful)
• warranty 1-10 years (in Depending on the manufacturer).

FEATURES INSTALLATION

Installation of metal occurs on such a scheme . Metal fit in the sequence from the underlying elements to the overlying. Sheets disposes overlap by 20-25 cm (the lower tier starts at the top) and attached to the crate special screws, screws, nails or stainless steel screws 4,8 x 35 mm.

Due to the fact that sheet metal have the standard form and the size (width more than 1 m, length of 6-8 m), sometimes they have to cut. The more complex and unusual shape the roof, so often have to do it. For cutting use metal snips, hacksaw, scissors, "rodents" or hand circular saw with solid cloth. is important to remember that cutting metal work angle grinder is prohibited. For through the minimization of the number of joints metal Arsenal is an increase in strength and watertightness of the roof.
