Stainless Steel Grating

Introduction of stainless steel grating.

Stainless steel grating, also known as stainless steel grating, stainless steel grating, stainless steel grating is its material is stainless steel grating, its production process is similar to the ordinary steel grating, except that it does not need to use paint or hot dip galvanizing and other anti-corrosion treatment, but the need to use the surface polishing treatment to remove the weld slag or scar left in the welding process. Stainless steel grating selection and carbon steel grating selection, its surface treatment has acid white, passivation, polishing and other ways, stainless steel material generally choose 304, 316, 316L, 301, etc..

Stainless steel grating material.

1, 304: general corrosion resistance, commonly used, recommended.

2, 316 (316L): strong corrosion resistance, more expensive.

3, 301: weak corrosion resistance, cheaper.

Stainless steel grating classification.

Stainless steel grating can be divided into flat grating, toothed grating and I-grating according to the different flat steel, and there are more than 200 specification varieties (according to different use environment, different protective treatment can be applied to its surface).

Stainless steel grating production method.

Including machine press welding and hand-made two kinds.

1、Machine press welding uses high pressure resistance press welding machine, the robot automatically places the cross bar across the uniformly arranged flat steel, and presses the cross bar into the flat steel by powerful welding power and liquid pressure, so that you can get the high quality steel grating with strong welded joints, stability and strength.

2、Hand-made steel grating is punched on the flat steel first, then the cross bar is put into the hole and spot welded, there will be a gap between the cross bar and the flat steel, but every contact point can be welded to achieve the same dissolution connection of the flat steel and twisted steel, so the welding will be stronger and the strength will be improved, but the appearance is not as beautiful as the pressure welding. Whether by machine or by hand, welcome to consult with Shangbang Steel Grating Factory.

Features of stainless steel grating.

1, light weight, high strength, large load-bearing capacity, economical material saving, ventilation and light transmission, modern style, beautiful appearance.

2、Anti-slip, easy to install, easy to clean, durable.

3, strong anti-corrosion ability, anti-oxidation, wide use, long service life.

Use occasions of stainless steel grating.

1、The use of harsh environment, the need to resist acid, alkali corrosion occasions (such as chemical plants, environmental protection equipment, sewage treatment plants, ethylene plants, etc.).

2、The occasions with high requirements for hygiene (pharmaceutical, food processing, hotel).

3、The occasions with high requirements for appearance (such as landscape, theater).

In addition, steel grating made of stainless steel is widely used in shipbuilding, petrochemical, food processing plants, power plants, sewage treatment plants, chemical plants, oil refineries, steel plants, machinery manufacturing plants, cement plants, bridge projects, municipal engineering projects and other fields, especially in some environments with high requirements for anti-corrosion, usually used as stainless steel gutter covers, stainless steel stair treads, stainless steel grating ceilings, stainless steel rainwater grate, etc.

Stainless steel grating surface treatment.

1、Acid washing, the surface is matte gray-white. (Pickling: By pickling in the pickling pool and using passivation solution and deionized water treatment, the passivation film lost due to processing will be restored.)

2、Electrochemical polishing, the surface is brighter and has a higher finish. (Electrochemical polishing: carried out in an electrolytic cross bath to produce a uniformly colored polished surface and remove dirt.)

3、Finished products are heated and polished, followed by electrochemical polishing for chrome plating, which can achieve a mirror effect.
