The grating with a pitch of 30mm between bearing bars is the most widely used type in the industrial field. Among normal types, it has the strongest resistance to surface lash.
The grating with a pitch of 40mm between bearing bars is the most economical and lightest type. It is the best choice for occasions when the span is small.
The grating with a pitch of 60mm between the bearing bars and a pitch of 50mm between the cross bars is developed especially for the mining industry, solving the problem of mineral splash on the plate. It is often appointed for use in processing works of the mining industry.
The grating with a pitch of 30mm between bearing bars and 76mm between cross bars is the most popular type used domestically and internationally, suitable for many applications such as walkways, platforms, etc.
Stainless steel grating is regarded as industrial-grade bar grating, which is extremely strong, durable, and corrosion resistant for all load-bearing applications, primarily used for pedestrian and light vehicle traffic.
| Type | Description | Tensile Strength | Yield |
|---|---|---|---|
| 304 | Good corrosion resistance, high tensile strength, excellent for chemical processing, food industries, power plants, and wastewater treatment. Used in high-temperature applications | 75,000 psi (min.) | 30,000 psi (min.) |
| 316 | Better corrosion and pitting resistance than type 304, and good heat resistance, used in chemical, pulp, and paper processing, marine environments, textile equipment, and petroleum refining. | 75,000 psi (min.) | 30,000 psi (min.) |
