Jinghuasteel grating is strictly manufacturing according to Chinese standard YB/T4001.1-2007 , can also be in accordance with the requirements of customers, according to national standards for production The material of all the bearing bars and cross bars have a high quality .The first-class staff and production equipment assure the high quality ofJinghua steel grating.
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 Garting:
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.
