HOT-DIP GALVANIZED is molten iron and steel materials that are lost in a bath of zinc surface with zinc and zinc compounds is the process of making the protective coating.
The best projects begin in galvanizing
Each type of iron and steel products can be galvanized by hot dipping method
but the chemical composition of the material, homogeneity of composition, surface condition, such as variables, to achieve successful results are the most important factor. These coating thickness, structure and directly affects the quality.
Galvanized in accordance with standards of the material to be coated is affected by the chemical structure of material.
Iron and steel products will be wrapped with SDG method differences in chemical composition of different unwanted images after galvanizing, thick coatings and coating quality standards will lead to impropriety.
Materials must be carefully selected for quality coating.
The structure of steel to comply with standards;
- % Si < 0,04 veya 0,15 < % Si < 0,25
- % C < 0,25
- % P < 0,05
- % Mn < 1,30
- % Si + ( 2,5 % P ) < 0,09
- % C < 0,25
- % P < 0,05
- % Mn < 1,30
- % Si + ( 2,5 % P ) < 0,09
The amount of silicon contained in the steel galvanizing pot reaction effects.
Carbon and silicon and the structure will affect the color of galvanized. These elements of the layer structure, the effect of growth by increasing the speed show. As a result of the increased growth rate of the coating over time and the viscosity of the fragility is less than.
Pieces of source object before galvanizing should have the same quality.
Materials will be shown for selection makes it possible to encourage high-quality coating of the galvanized steel, but the color differences in different quality and can deliver, to prevent coating of the material to be homogeneous on the surface.
