First of all, based on the application site and environment, if it is used to lay a steel structure platform as a walkway, we call it a platform steel grating; if it is used on municipal cables and long narrow ditches for ventilation and drainage, we call it a ditch cover. ; Used for the steps on the stairs, we use them as step boards for the passage up and down the stairs, also called (steel ladder).
Secondly, we distinguish according to the surface treatment method of steel grating. After the steel grating is welded and formed, hot-dip galvanizing is used as the surface treatment, which is called hot-dip galvanized steel grating. Hot-dip galvanized steel grating has the characteristics of anti-corrosion and long service life, and is the most commonly used product by buyers; if cold-dip galvanized steel grating is used, Galvanizing as a surface treatment method is called electro-galvanized steel grating. Cold-dip galvanizing is lower in cost than hot-dip galvanizing. However, because the zinc layer is easy to fall off and rust will occur in a short period of time, it is rarely used; Welding without any treatment is called black chip, it is easy to rust, and we generally do not recommend it. If the surface is painted, we call it a painted steel grating.
In addition, according to the different flat steel profiles used in the welding of Anping steel grating, it can be divided into toothed steel grating, plug-in steel grating, heavy-load steel grating, special-shaped steel grating, etc. Tooth-shaped steel grating has good anti-skid effect and is suitable for common offshore drilling platforms, shipyard platforms, etc.; if the load capacity is large, plug-in or heavy-duty steel grating is often used.
