ISO9001 Certified Galvanized Steel Stair Treads with Perforated Metal for Pedestrian Traffic

Galvanized Steel Grating, is extremely strong and durable for all load bearing applications and is primarily used for pedestrian and light vehicle traffic. Our galvanized coating process provides for years of corrosion resistance in acidic and high moisture environments.

Galvanized Steel Expanded Metal is a sheet product that has been slit and stretched to diamond shaped openings. Galvanized expanded metal offers savings in weight and allows free passage of light, liquid, sound and air while providing corrosion resistance in harsh environments.

GLOSSARY OF TERMS
1. Bearing Bar - Loading carrying bars made from steel strip or slit sheet or from rolled or extruded aluminum, extending in the direction of the grating span.
2. Cross Bar - The connection bars, made from steel strip, slit sheet or rolled bars or from rolled or extruded aluminum, which extend across the bearing bars, perpendicular to them. They're bent into a corrugated or sinuous pattern. Where they intersect the bearing bars, welded, forged or mechanically locked to bearing bars.
3. Bearing Bar Centers - The distance center to center of the bearing bars.
4. Cross Bar Centers - The distance center to center of the cross bars.
5. Band - A flat welded to a side or end of grating panel. Or along the line of a cutout, extending neither above nor below bearing bars.
6. Toe Plate- Also called kick plate. A flat bar attached flat against the outer edge of grating or rear edge of tread. Projecting above the top surface of grating or tread to form a lip or curb.
7. Length - Refer to span of grating.
8. Width - The overall dimension of grating panel. Measured normal to the bearing bars.

GNEE Steel Grating Application

Steel grating are designed and manufactured for various industrial and civil constructions in city road, gardens, yard, airport, railway and industrial engineering.

• Hot dip galvanized steel grating is the best choice for steel platforms in airports. Grating with 30 × 3 mm thick load bearing bars with a pitch of 30 mm and traverse bars at 50 mm or 100 mm is the suitable one.
• Steel grating, with robust design and spanning abilities, is very strong and safe for the support of floors and elevated walkway. It can be used for ceiling, interior decoration, platform aisle, ventilation windows, (Wells), advertising plaque and other construction.
• Widely used in the petrochemical industry, power plants, waterworks, sewage treatment plants, municipal works, sanitation projects in areas such as platforms, corridors, bridge, ditch cover, covers, ladders, fences, rails, and so on.
