How to choose high quality steel grating？

Steel grilles have been widely used in our daily lives. Do you know what factors determine the quality of steel grilles in steel grating manufacturers? Below is a detailed introduction for everyone:

A steel grating is an open steel component that is orthogonally combined with load-bearing flat steel and horizontal bars at a certain spacing, and fixed by welding or locking; Horizontal bars are generally made of twisted square steel, and can also be made of round or flat steel. The materials are divided into carbon (C) steel and stainless steel (stainless acid resistant steel).

Steel grating is mainly used as a steel structure platform plate, trench cover plate, steel ladder step plate, building ceiling, etc.

Steel grilles are suitable for alloys, building materials, power plants, and boilers. Shipbuilding. The petrochemical, chemical and general industrial plants, municipal construction and other industries have advantages such as ventilation, light transmission, anti slip, strong load-bearing capacity, aesthetic durability, easy cleaning, and easy installation. Steel grilles have been widely used in various industries both domestically and internationally, mainly as industrial platforms, stair treads, handrails, passage floors, railway bridge sidewalks, high-altitude tower platforms, drainage ditch covers, manhole covers, road barriers, three-dimensional parking lots, fences for government agencies, schools, factories, enterprises, sports fields, garden villas, as well as external windows for residential buildings, balcony guardrails, guardrails for expressways, railways, etc.

1. Tolerance

Is the public service of flat steel, including diagonal lines, controlled within a very good scale? Does the public service of flat steel comply with national regulations and standards. The steel grating is an open steel component that is orthogonally combined with load-bearing flat steel and horizontal bars at a certain spacing, and fixed by welding or locking; Horizontal bars are generally made of twisted square steel, and can also be made of round or flat steel. The materials are divided into carbon steel and stainless steel.

2. The quality of flat steel raw materials

Flat steel is the most important part of steel grating, bearing the maximum load-bearing capacity in the entire structure. The grille panel does not accumulate dirt, rain or snow, does not accumulate water, is self-cleaning, and is easy to maintain. Some manufacturers, in order to reduce production costs and earn more money, will use flat steel made by secondary processing of scrap steel.

3. Proofreading and welding of flat steel

After the purchase of flat steel, it may not be completely parallel. In addition, during transportation, lifting may cause slight bending of the flat steel. Don't underestimate this point of bending. If the steel grating has a slight bending, it may not be welded properly. Perhaps the welded steel grating is deformed, so proofreading is very important.

Welding is a very important part, and the quality of welding will directly affect the load-bearing capacity and lifespan of the steel grating. Steel grating is welded from flat steel and twisted steel. It is durable and more affordable compared to other products. Its main use is in power plant platforms, parking lot platforms, maintenance platforms, ditch covers, and step boards. The steel grating is an open steel component that is orthogonally combined with load-bearing flat steel and horizontal bars at a certain spacing, and fixed by welding or locking; Horizontal bars are generally made of twisted square steel, and can also be made of round or flat steel. The materials are divided into carbon steel and stainless steel. If the welding is not good enough, it may not take a few days to start welding directly, and such a steel grille cannot be used.

4. Hot dip galvanizing (hot-dip galvanizing) treatment of steel grating

Hot dip galvanizing (hot-dip galvanizing) is very important for steel grilles, which is the appearance of steel grilles. The first criterion for customers to judge steel grilles is the hot-dip galvanizing on the surface. Hot dip galvanizing is not only beautiful, but more importantly, its rust prevention ability. If the quality of hot dip galvanizing is good, the natural lifespan will be longer.

5. Packaging and shipping

The final point is to pack and ship the steel grating. When loading, do not use a forklift to randomly place the steel grating just because it is solid and not easily damaged. When loading the steel grating, handle it gently, and the forklift should not pick it up at will, especially for thinner steel gratings, which can cause deformation of the steel grating.
