Drainage Ditch Steel Plate Trench Covers Drainage Steel Grating

Steel grid surface treatment:
Hot dip galvanized, cold galvanized, paint, dip anti-rust oil, do not deal with (general stainless steel do not deal with). Method of making steel lattice plate: Pressed-welded steel grid is made up of load flat steel and horizontal bar arranged in warp and weft at a certain distance. It is welded into the original plate by hydraulic resistance welding automation equipment of 200 tons, and processed into the product required by customers through cutting, opening, edge packing and other procedures. Load flat steel spacing:The center distance between two adjacent flat steel receiving loads is usually 30mm and 40mm. Cross bar spacing:The center spacing of two adjacent cross bars is usually 50mm, 100mm, two kinds, can be produced according to customer requirements. Superiority:Material saving:The most economical way of material under the same load condition, correspondingly, can reduce the material of supporting structure. Reduce investment:Save material, save labor, save time limit, avoid cleaning and maintenance. Construction is simple:In the pre-installed support with bolts clamped or welded fixed, one person can complete.

1.Welded Steel Grating

When selecting a bar grating product, consider Welded Steel Grating first. Usually our most economical products, they provide a comfortable walking surface with nearly 80 percent open area. This, combined with the positive welded cross bar/bearing bar intersection, make these products our most popular. Manufactured from ASTM A-1011 carbon steel, welded gratings are recommended for nearly all industrial floorhen selecting a bar grating product, consider Welded Steel Grating first.

2.Swaged Aluminum Grating

Aluminum grating products are light in weight, resistant to atmospheric corrosion, non-sparking and offer an attractive appearance. These characteristics make aluminum grating especially suitable for water and sewage treatment facilities, marine environments, food processing and petro-chemical installations.

3.Pressure Locked Grating

Grating Pacific offers two distinct types of Pressure Locked Gratings which are identified by their method of assembly. Manufactured without the introduction of heat or riveting, these gratings provide a finished product with attractive architectural lines. This pleasing appearance makes Pressure Locked Gratings ideal candidates for architectural and ornamental applications such as grilles, screens and fences. Additionally, pressure locked methods of manufacturing allow for the production of close mesh gratings with minimal open area.

4.Stainless Steel Grating

When considering grating for food processing applications,shipboard use, or highly corrosive environments, Stainless Steel Grating is often the most cost effective product.Commonly manufactured in 300 series alloys, stainless steel gratings are assembled by welding or pressure locking to suit the specific needs of each application.To specify Stainless Steel Grating, the type of grating is indicated by designating one of the three profiles shown combined with the bearing bar/cross bar spacing illustrated in the table below.
