| Definition of Steel Grating: | | |
| Steel grating is a kind of open steel member with its bearing bars & cross bars jointing at their intersections either by welding or by locking. |
| General Information of Stell Grating: | | |
| 1\Bearing bar-A flat bar withstanding the main load is in consistent with the two adjacent bearing bars. |
| 2\Bearing bar pitch-The distance center to center of the two adjacent bearing bars. |
| 3\Cross bar-The connecting bars,made from twisted bar\round bar or flat bar,which extend across the bearing bars. |
| 4\Cross bar pitch-The distance center of the two adjacent cross bars. |
| 5\Lengtn-The maximum dimension of a grating panel,measured parallel to the bearing bars, & in the same direction as the bearing bars. |
6\Width-The maximum dimension of a grating panel,measured perpendicular to the bearing bars, & in the same direction as the cross bars.

| General Usage of Grating : | | |
Flooring | all kinds of Trench cover | Catwalk | Window and machinery safe guards | Mezzanines/decking | Wash rack | Stair tread | Ventilation screen | Fencing | Storage rack | Vault bin floor | Suspended ceiling | Ramp | Drainage pit cover | Dock/ Warehouse | |

| Steel mesh panels types: | | |
| There are three kinds of steel gratings distinguished by different bearing bar typesThe respective of features are as follows: |
| 1\Plain: the most widely used gratings,available for flooring sidewalk,all kinds of ditch cover,stair tread,etc. |
| 2\Serrated:best non-skid property & safety compared with plain grating. |
3\I-shape:lighter,Not substantially weaken the case of load capacity more economical and practical comparing with plain grating.
