Galvanized sheet steel is a popular type of rolled metal, which is actively used in the national economy, in the industrial sector and in civil construction. The assortment is easily amenable to various processing methods, can be cut to a suitable size and has a wide range of applications. The zinc layer protects the metal from corrosion for several decades.
Advantages of galvanized steel product
The main advantage of this type of rolled metal is the presence of stable and high-quality galvanizing. If it is applied over a sheet blank, taking into account the requirements of state standards, a diffusion reaction occurs. In other words, the molecules of both substances (steel and zinc) penetrate deeply into each other's structure, forming a high-quality compound. It is very difficult to break it, even during the subsequent processing of sheet metal.
Also, other advantages of the material are highlighted:
- there are different ways to apply a protective layer to it;
- sheet thickness also varies;
- he is not afraid of constant exposure to aggressive environments;
- has a low cost.
Features of galvanizing application
The scope of this rolled metal product is very extensive. Products for various types of industry, construction, ventilation systems, roofing, etc. are made from it. If painting and rolling are supposed to be used, galvanized sheets with general parameters are used. If the production of building materials is required, the raw material is profiled by cold rolling. If it is planned to create products for the national economy, the craftsmen subject the steel to technological stamping.
Galvanized steel is used to make strips, water pipes, parts for a folded roof, cable trays, corrugated board and much more. The price for sheet metal is formed on the basis of its thickness and density of the zinc coating. Classes of protective coating: increased (from 40 to 60 microns), 1st (from 18 to 40) and II (from 10 to 18).
Choice of zinc coating
Initially, the steel sheet must meet the tasks set by the buyer. At the same time, the presence of minor defects on the surface of the assortment is permissible - small influxes, darkened areas, light spots, small traces of drips. Also, shells, rough areas, scratches, abrasions and traces of rolling shafts. The presence of chips and a heterogeneous structure indicates a violation of the galvanizing technology.
