Based on the material, steel grating made of Q235 low-carbon steel is called carbon steel grating. Depending on the constituent materials, there are also stainless steel gratings, fiberglass gratings made of polyester sheets, etc.
Polyester gratings are more resistant to acids and alkalis than carbon steel gratings, and have advantages such as anti-aging, insulation, and non-magnetic properties.
Carbon steel gratings are cheaper and more versatile for non-strong acid or non-corrosive working environments, featuring high strength, lightweight structure, and longer lifespan.
Hot-dip galvanized steel gratings also have resistance to alkali corrosion.
The service life of carbon steel gratings is generally 20 years. After a period of use, hot-dip galvanized steel gratings may experience slight color changes after five years, but there will be no fundamental quality change. Carbon steel gratings come in a full range of models. Electro-galvanized and painted trench covers, on the other hand, will become rusty. Therefore, electro-galvanized and painted trench covers are only suitable for indoor use in non-corrosive conditions.
Carbon steel gratings are available in a full range of models. Carbon steel grating is constructed by welding flat steel bars and crossbars (twisted steel, round steel, or flat steel) at specific intervals. The edging can use the same specifications as the load-bearing flat steel bars, or different specifications, depending on the user's requirements. Different specifications and models of carbon steel grating result in different prices. A variety of specifications and models are available.
To prevent corrosion, carbon steel grating can undergo hot-dip galvanizing, cold-dip galvanizing, or painting. The price varies depending on the surface treatment method used. Hot-dip galvanizing is the best and most commonly used method, but it is slightly more expensive than other surface treatments.
