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. |

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. |
Plain | serrated | l-shape |
The Most Popular Specification of Steel Grating: | |||||
1\Steel grating with 30mm bearing bar pitch is the most widely used in industrial area.Among the general series.it maintains the strongest resistance to impulsive force. |
