Steel structure surface treatment България

Improve corrosion resistance, form a protective film, extend service life.

Improve the aesthetics, make the surface more smooth and flat.

There are generally several methods for processing such as sandblasting, shot blasting, pickling, grinding wheel, etc. Processing units can choose processing methods according to their own conditions. Among the above methods, the anti-slip coefficient of the friction surface treated by shot blasting and sand blasting is higher and the dispersion is smaller, so it is the best treatment method.

Shot balsting

Sand blasting (shot). Sand blasting (shot) should choose dry quartz sand, particle size is 1.5-4.0mm, wind pressure is 0.4-6N/m2, nozzle diameter Φ10mm, nozzle distance from the steel surface 100~150mm, the steel surface after processing is the best gray.

After sand blasting, the material will be galvanized or painted, which will be stronger and better.

  Steel structure usually have two kind of surface treatment.

1.Galvanized

Galvanizing provides excellent protection, isolating the original parts from moisture, is highly corrosion resistant, improves the strength, toughness, wear resistance and other properties of the substrate, giving the metal surface an attractive, shiny silver appearance

2.Steel structure paint

local materials, the general company workers can brush directly, customized color. With unique elasticity and ductility, it can withstand the frequent changes of thermal expansion and contraction without cracking and falling off, which plays a long-term and stable role in the protection function of steel structure placed in the natural environment.

The primer should be fully dried after brushing, and the general drying time is about 24 hours.

After drying, write the installation number, which is convenient for customers to install according to the drawings, and finally load the container
