What factors affect the quality of steel grating?
HomeProfessional Knowledge 〉 What factors affect the quality of steel gratings?

1.Tolerance

The public service time including the diagonal of the flat steel is controlled within a very good scale. Does the public service of the flat steel meet national standards and national standards?

2, the quality of flat steel raw materials

Flat steel is the most important part of the steel grating , and bears the largest load in the entire structure. In order to reduce production costs and make more money, some manufacturers will use flat steel made from secondary processing of scrap steel.

3. Proofreading and welding of flat steel

Flat steel may not be completely parallel after purchase. In addition, the flat steel may be slightly twisted due to lifting during transportation. Do not underestimate this twist. If there is a slight twist in the steel grid plate, it will cause welding to fail, and maybe The resulting steel grating is deformed, so proofreading is very important.

Welding is a very important part. The quality of welding will directly affect the carrying capacity of the steel grating and its life. If the welding is not good, it may be opened in a few days without using such a steel grating.

4. Hot-dip galvanizing treatment of steel grating

Hot-dip galvanizing is very important for steel gratings. This is the appearance of steel gratings. The first criterion for customers to judge steel gratings is the appearance of hot-dip galvanizing. Hot-dip galvanizing is not only beautiful, but also its anti-rust ability. The quality of hot-dip galvanizing is good and the natural life is long.

5.Packed and shipped

The final point is that the steel grating is packed and shipped. Do not think that the steel grating is solid or damaged when you load it. Use a forklift to arbitrarily place the steel grating. You can't do it all at random, especially for thin steel gratings, which simply causes the steel gratings to deform.
