Safety grids
Safety grids for functional or decorative use are suitable for any environment. Due to the wide range of varieties on offer, they guarantee a solution in terms of their great stability, grip, durability and drainage qualities as well as their use as a means of passage or the range of lighting options.

For the full range of materials and finishes: 150 mm / 200 mm / 250 mm / 300 mm.
Standard height:
For the full range of materials and finishes: 30 mm / 40 mm / 50 mm / 75 mm.
PS-OFF
PS-OFF safety grid has the same advantages as PS-PERF safety grid. It grips extremely well due to the perforations stamped at the top end which allow liquid to drain through.

Technical infos
Structures
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).

Serration
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.
