Introduction of  Ditch Cover Steel Grating

Trench cover plate refers to the steel grating cover plate placed on the gullies such as sewer, rainwater channel and cable trench. Its main purpose is to drain water and ensure the safety of personnel and vehicles, and sometimes to protect the safety of gullies. There are mainly three kinds of cement ditch cover, cast iron ditch cover and steel grating ditch cover. Due to the characteristics of low cost, beautiful appearance, many types of specifications, high impact resistance and high bearing capacity of steel grating trench cover plate, steel grating trench cover plate has become a commonly used trench cover plate product.

The phosphating process steps of anti-theft ditch cover plate

alkaline degreasing agent → normal temperature water washing → surface conditioning → low temperature phosphating → normal temperature water washing → drying → coating.

After these steps, the phosphating treatment of galvanized sheet is basically completed.

Purpose of steel grating trench cover plate:
Steel grating trench cover plates are widely used in ditches and cable trenches in municipal roads, garden facilities, residential quarters, stadiums, coal mines, project sites and other places.
 Surface treatment method of steel grating trench cover plate:
The steel grating trench cover plate is usually hot-dip galvanized on the surface, and sometimes painted. The hot-dip galvanized steel grating trench cover plate has strong corrosion resistance. If it is used as a cable trench cover plate, a layer of checkered plate is often welded and covered on the surface of the trench cover plate to make the cable trench cover plate in a composite way.

 Material of steel grating trench cover plate:

Steel grating trench cover plate is usually made of low carbon steel Q235, and sometimes stainless steel. The flat steel of stainless steel grating trench cover plate is made of 304 and 316 materials. If the skid resistance of the steel grating trench cover plate is considered, the tooth shaped flat steel can also be used for production, and the tooth shaped flat steel can also be used for production. The correlation between products is reflected here. The surface of trench cover plate is generally hot-dip galvanized, so we often call it a special product of galvanized trench cover.

 Classification of steel grating trench cover plate:
1. GT type ditch cover plate:
(also known as GT type common side ditch, cross section ditch, steel grating ditch cover)
The steel grating trench cover of carriageway is divided into side trench cover and cross-section trench cover according to the direction of carriageway. The bearing flat steel perpendicular to the direction of the vehicle is called the side ditch cover, and the bearing flat steel parallel to the direction of the vehicle is called the transverse ditch cover.
