Galvanized gutters - strong shackles for rain

galvanized drains that special about them?

To date, you have access to a system of draining rainwater simply galvanized steel with an additional polymer coating.First, let's look at exactly what this material can attract attention.First and foremost - it is fireproof.Agree, if you have all the money invested in the country house, where you do not plan to rest on short visits, and to live all year round, it is very important to best protect it from fire.Drains will be galvanized steel with the right choice.

Sheet steel without a polymer coating has a very low noise insulation, the installation of conventional metal gutters in the house will be distinctly heard the sound of rain and even wind.

second positive quality is also very important - very high strength with relative ease, namely - up to 490 MPa, with specific weight 7.85 g / cm3. lasting only drains of titanium-zinc alloy, but they are disproportionately expensive, more than 10 times .Gutters of galvanized coated plastic are not inferior in durability, because they have strong protection against corrosion.Admittedly, no such additional barrier rust begins to corrode the metal in 5 years.

Gutters of galvanized steel - which is to be feared?

galvanized itself, as has been said, it is short-lived, especially if there are favorable conditions for various types of corrosion.In particular, when there are scratches the surface of galvanizing, eventually that is where there is rust.However, not only the constant exposure to moisture can cause damage when in contact with other metals, even slightly damaged gutters made of galvanized steel may be exposed to galvanic corrosion.The reason is the potential difference between some metals.For example, it is not recommended to install drainage systems made of galvanized steel under the copper roof.

There is this kind of damaging effects, as the bitumen corrosion.There she was active as a result of exposure to sunlight and moisture in the soft roof with bituminous base.Unfortunately, this material is, for all his excellent waterproofing qualities, being split, forming an acid reaction to the level of pH - 22. As a result, the usual galvanized metal can not withstand such a test, and even polymer coating does not help, the best option in this case - aluminum orstainless steel.Therefore, drainage system made of galvanized steel is better to install with the same roofing.

galvanized gutter system - Selection Criteria

Select metal gutters can be shaped, and if they are coated with a polymer coating, then by color.With regard to the form factor, the trays are semi-circular, rectangular (square) and relief, the appropriate form must be used brackets and plugs.However, galvanized water drainage system is not one of the gutters, pipes also vary in cross-section, you can choose round or square version.

All elements are usually made in the general style, that is, when the square tube, the funnel rainwater and galvanized same.However, unlike plastic packages, metal trough not connected to the funnel, and hanging above it so that the water jets exactly fall into the mouth.In respect of fasteners and profitable steel water drainage system, the steel has a higher rigidity than plastic, and brackets can be positioned at a greater distance. If the polymer rain drain holders mounted with a gap of 60 centimeters, then the metal can extend this distance to 90 .
