Language explain

1.  Load Bar-LB(Bearing Bar):

A longitudinal load-carrying member of uniform section spanning between sipports,which can be plain or serrated.

2.  Cross Bar(Transverse Bar):

The connection bars,made from twisted square bar or round bar,which extend across the bearing bar,usally perpendicular to them.

3.  Banding Bar:

A flat bar welded to the end of a grating panel,or along the line of a cutout,and extending neither above nor below the bearing bar.

4. Pitch

Pitch includes the pitch of bearing bar and the pitch if cross bar. It means the diatance center-to-center of bearing bars or cross bars.

5.  Length

The dimension of a grating panel measured parallel to the bearing bars.

7.  Width

The overall dimension of a grating panel, measured perpendicular to the bearing bars.

For example, if bearing bar pitch is 30mm , thickness of bearing bar is 5mm , the largest width is 995mm . If bearing bar pitch is 40mm , thickness of bearing bar is 5mm , the largest width is 1005mm .

8.  Steel grade

Refers to steel-for example ASTM A6.

9.  Steel grating standard

According to YB/T4001.1-2007

10.  Hot dip galvanized standard
