steel grating weight Types: Serrated Steel Grating and Plain Steel Grating.

♣plain type: One of the most wiedly used gratings, available for flooring, sidewalk, drainage pit cover, stair tread, etc.

♣serrated type: Better Non-skid property & safety compared with plain grating.

♣I-shape type: Lighter, more economical and practical comparing with plain grating.

steel grating weight Surface Treatment:

1. Hot Dipped Galvanized Steel Grating: according to GB/T13912-92 standard :the average zinc thickness is more than 610g/m²(flat bar ≥5mm) and 460g/m²(flat bar <5mm).

2. Painting Steel Grating: according to the clients' requirement, choose japanning dipped coating.

3. No Surface Treatment Steel Grating.

steel grating weight Packing:

Normally steel grating packed in pilling up ways with two pieces of square wood on both upperand bottom sides.There are four or six pieces of M10 long bolt penetrading the gratings and screwing together. It is suitable for loading and unloading by fork-lift and crane.

steel grating weight Application:

1. Steel grating is widely used by various plants such as electric power, petroleum, chemical industry, metallurgy industry, machinery industry.
2. Steel grating is also widely used in shipbuilding, harbor, oceanographic engineering, building, paper mills, cement plant, medicine, spinning and weaving.
3. Steel grating is applied in food stuff factory, transportation, municipal administration, parking lot, etc.

steel grating weight Advantages:

1. Attractive appearance: Simple outline.silver colour,and modern.

2. Optimum water draining: Water leakage area is 83%,which is two times larger than that of cast iron.

3. Hot dip galvanized surface:Good anti-rust performance,maintain free and replace free.

4. Saving investment: With large span,the cost is lower than that of cast iron when under heavy load.

5. High strength:With strength: With strength and toughness far higher than those of cast iron,it can be used in the environment with large span and heavy load,such as the wharf and the airport.

6. Many specifications available: The requirement of different environments,loads, spans,sizes and shapes can be satisfied.
