Grating
Steel bar grating is also called steel graating, it is produced of steel flat bar and cross bar(twisted steel, steel rod or flat bar) in a certain distance by welding process.
The steel bar grating is mainly used as ditch cover plate, steel structure platform , steel ladder step, etc. The cross bar is generally using twisted steel. And the steel bar grating is generally made of carbon steel, and its surface is hot-dip galvanized, which can prevent corrosion. It can also be made of stainless steel. The steel bar grating has the properties of ventilation, lighting, heat dissipation, anti-skid and explosion-proof.
Steel used as building materials in shipbuilding, petrochemical, chemical and general industrial plants, municipal construction and other industries, it has the advantages of ventilation and light transmission, anti-skid, strong bearing capacity, beautiful and durable, easy to clean, easy to install and so on. It is been widely used as industrial platform, ladder pedal, handrail, passage floor, railway bridge side road, high-altitude tower platform, drainage ditch cover, well cover, road fence, three-dimensional parking lot, factories and other areas.
Product Features:
●Large loading strength.
●Easy for installation.
●Long service life.
The Main Parameters of Steel Bar Grating
The steel bar grating can be divided into Bearing bar-cross rod welding type and plug in welding type according to the production craft.
 |  |
The main parameters of Bearing bar-cross rod welding type are the width and thickness of bearing bar, the diameter of cross rod, the pitch of bearing bar and cross rod, the mesh width and length.
The main parameters of plug in welding type are width and thickness of flat bar, the pitch of flat bar, mesh width and length.
●The Common Flat Bars Types
●The Common Cross Rod Types
By using different types of material, there are various of steel bar grating types available.
●The Bearing bar-cross rod welding types
 |  |
| Plain flat bar with twisted steel rod | Plain flat bar with round steel rod |
 |  |
| Serrated-flat bar with twisted steel rod | Serrated-flat bar with round steel rod |
 |  |
| I-shape flat bar with Twisted steel rod | I-shape flat bar with Round steel rod |
 |  |
| I-shape serrated flat bar with Twisted steel rod | I-shape serrated flat bar Round steel rod |
●The plug in welding types
 |  |
| Plain flat bar plug in welding | Serrated-flat bar plug in welding |
Clients can choose the suitable type according to your needs
For the Bearing bar-cross rod welding type, because the strength of flat bar and cross rod is different, so the grating has different direction. When using the grating, the two sides of grating need to be set in the main structure.
