MESH

Spacing between bearing bars (BB) and transverse bars (TB). Mesh created in this way has two characteristics: mesh width and mesh centre spacing (pitch).

• Mesh width: the width of the opening that is between the BBs and TBs
• Mesh centre spacing (pitch): the distance between the centre of BBs and TBs (for example, the distance between the centre of one bearing bar and the centre of the nearest adjacent bearing bar)

MESCH GROUP/TYPE 

 Mesh is made up of two values (in mm), where the first dimension is the distance between adjacent bearing bars, and the second dimension being the distance between adjacent transverse bars (for example: 33.33 x 33.33; 33.33 x 11.11; 55.55 x 55.55; etc.).

For convenience’s sake, the term “mesh gauge” is more frequently used (for example: 30 x 30 - 30 x 10 - 50 x 50 - etc.)

BEARING BARS (BB)

Straight rods bearing the weight and arranged in rows at right angles to the transverse bars and supports. 

TRANSVERS BARS OR CROSS BARS (TB)

Arranged at right angles to the bearing bars, and bonded to the bearing bars by the exertion of high pressure (press-locked grating) or by electrowelding (press-welded grating). The transverse bars are manufactured respectively in “straight metal” or as square, twisted bars.

BB AND TB GAUGE

 this is defined by two values (in mm), where the first corresponds to their height and the second to their thickness. Gauge examples: 30 / 2; 30 / 3; 40 / 3; etc...

RANGE

Gap between the supports on which the ends of the bearing bars rest.

IMPERMEABILITY - SECURITY BARS

security mesh uses the following mesh gauge: 30 x 19; 19 x 30; 19 x 19; etc. It is recommended for industrial environments (14122 standard) and allows nothing exceeding a 20 mm diameter ball to pass through it.

SUPPORT BRAKET

Bracket welded to the ends of the grating rendering it suitable for certain uses (for example: shelving, guttering).

SIMPLE ANTI-SLIP SERRATION ON BB

Various types of serration can be applied to bearing and/or transverse bars. Please note that this double serration option (for BBs as well as TBs) is only applicable to press-locked grating. Serration can only be applied to bearing bars for press-welded grating.

SIMPLE ANTI-SLIP SERRATION ON TB

Various types of serration can be applied to bearing and/or transverse bars. Please note that this double serration option (for BBs as well as TBs) is only applicable to press-locked grating. Serration can only be applied to bearing bars for press-welded grating.

DOUBLE ANTI-SLIP SERRATION ON BB AND TB

Various types of serration can be applied to bearing and/or transverse bars. Please note that this double serration option (for BBs as well as TBs) is only applicable to press-locked grating. Serration can only be applied to bearing bars for press-welded grating.
