Plug bar grating/welded bar grating/Steel Grating
The bearing grating length is the external grating dimension measured in the direction of the bearing rods (this applies even in the case that the grating length is shorter than the width thereof).
The non-bearing grating width is the external grating dimension measured in the direction of the filling rods.
The bearing rods are parallel grating chords supported on both ends and used to transmit the forces induced by the grating load.
The filling rods are chords sized as a rule to 10 x 2 mm maintaining the vertical position and stability of the bearing rods.
The mesh size is the axial distance between two adjacent bearing rods and two adjacent filling ones.
The border band is a steel band used as a border and reinforcement of the peripheral grating area; as a rule, the cross-sectional area of the border band is identical with that of the bearing rod of the grating.
Unidirectional Anti-Slip Arrangement
Indentations cut out in filling rods creating an effective anti-slip grating arrangement.
Supporting structure, as a rule steel or concrete construction, where gratings are anchored.
Rectangular, oblique and/or bow-shaped apertures in grating structures cut out in accordance with the Customer drawing or sketch.
