Channel is a metal profile with a cross section in the form of the letter "P". The upper part is called a jumper, and the rest of the shelves. Manufacturers use different production technologies. In addition, galvanizing is carried out to protect the metal coating. The company "EZI" carries out production and processing of metal structures.
Since the channel is often used to create load-bearing structures, they require the application of anti-corrosion protective coating. This is one of the few ways that helps to effectively deal with the appearance of corrosion and rust. A layer of zinc will not waste time and money on the application of useless paints, which quickly lose their properties, as well as protects against deformation and chipping during installation and transportation.
The process of galvanizing the channel is carried out on specialized equipment and only according to all the rules of the technological process according to GOST 9.307-89. The protective layer is applied to metal structures, which are made of carbon and structural steel grades. Due to zinc, a protective film with such properties is formed:
To date, the standard provides the following types of galvanizing:
Dip galvanizing is a popular procedure used by large enterprises in Europe, the USA and China. The method is very simple and easy to perform. It does not require large expenditures and the technology stands out for its ease. The pre-cleaned product is immersed in a special bath, where zinc is melted to a temperature of +450°C. Due to purification and etching in acid, the product is cleaned of scale and other defects, which will improve the quality of adhesion of the protective layer to the metal.
After all the preparatory work, the structure is immersed in the bathroom, where a certain time is spent in accordance with the technology. Upon completion, the item is dried in a special chamber resulting in a galvanized channel with a coating thickness of 40 to 200 microns.
