Marine hot-dip galvanized steel grating deck passage galvanized steel grating Q235 carbon steel

The hot-dip galvanized steel grating is an original plate made of load flat steel and cross bars arranged at a certain distance in longitude and latitude, welded on a high-voltage resistance welding machine, and deeply processed through cutting, cutting, opening, edge wrapping and other processes to become a finished product required by customers.

Hot dip galvanized steel grating is divided into the following types:

1. Hot dip galvanized steel grating: according to the manufacturing process, press welding hot dip galvanized steel grating and press locking hot dip galvanized steel grating are considered

2. According to the surface shape of hot-dip galvanized steel grating, it can be divided into toothed hot-dip galvanized steel grating and planar hot-dip galvanized steel grating

3. I-type hot-dip galvanized steel grating and composite hot-dip galvanized steel grating.

Identification method:

(1) Center to center spacing of hot-dip galvanized steel grating flat steel: according to series: Series 1 is 30mm; Series 2 is 40mm; Series 3 is 60mm.

(2) Center to center spacing of cross bar of hot-dip galvanized steel grating: 100mm for Series 1 and 50mm for Series 2. Other specifications can be customized.

(3) Hot dip galvanized steel grating flat steel: the material is Q235A or stainless steel, which has ordinary plane type, anti-skid tooth type and section I type. Common specifications include 20 * 5, 25 * 5, 25 * 3, 32 * 5, 32 * 5, 40 * 5, 40 * 3, 50 * 5, 65 * 5, 75 * 6, 100 * 8, 100 * 10, etc.

(4) Cross bar of hot-dip galvanized steel grating: round steel, twisted square steel, square steel or hexagonal angle steel made of Q235A or 304 stainless steel. Twisted square steel is drawn and twisted by a square die with a circular disk. Its common specifications are 5 * 5, 6 * 6, 8 * 8mm, etc.

Features: high strength, light structure: the firm mesh pressure welding structure makes it have the characteristics of high bearing capacity, light structure and easy lifting; Beautiful appearance and durability.

Application of hot-dip galvanized steel grating: it is widely used in platforms, walkways, trestles, ditch covers, well covers, ladders, fences, guardrails, etc. in petrochemical industry, power plants, water plants, sewage treatment plants, municipal engineering, environmental sanitation engineering and other fields.

Acid alkali corrosion ability: in the range of pH 6 to pH 12.5, a stable protective film is formed on the surface of the zinc layer, which has good corrosion resistance.

Examples of hot-dip galvanized steel grating

1. Heavy duty hot-dip galvanized steel grating is a hot-dip galvanized steel grating formed by welding flat steel 65mm-200mm wide and 5mm-20mm thick It is applicable to large freight yards, wharves, coal mine roads and bridges, and can carry large trucks.

2. Hot dip galvanized steel grating (flat steel spacing 40mm) the hot dip galvanized steel grating with flat steel spacing 40mm is the most economical and lightweight variety. It is the most ideal choice when the span is small.

3. Hot dip galvanized steel grating (the spacing between flat steel is 60mm) the spacing between flat steel is 60mm and the cross bar is 50mm. The hot dip galvanized steel grating is suitable for the mining industry and solves the problem of mineral splashing on the plate surface. It is often designated as a processing plant in the mining industry

4. Hot dip galvanized steel grating (spacing between flat steel is 30mm) hot dip galvanized steel grating with spacing between flat steel is the most widely used variety in the industrial field. Among the series of commonly used hot dip galvanized steel grating, it has the strongest resistance to surface impact

5. Hot dip galvanized steel grating (I-type flat steel) hot dip galvanized steel grating welded by I-type flat steel has the characteristics of light weight and large load. It is suitable for various occasions, especially walkways, visiting platforms, etc.
