Special gratings

Gratings have a wide range of use. In order to meet the most specific needs, JK Technic has developed a range of special, custom-made gratings.

Urban furniture

Urban furniture is a term used for any item that has been installed in a public space for the benefit of the public. JK Technic has a range of special gratings specifically designed for this type of use.

Tree guards

If you want to protect your trees in style and showcase them beautifully, JK Technic has designed a wide range of gratings for tree guards, with a selection of shapes and colours.

Benches

In press-locked steel, stainless steel or aluminium, benches become designer items. In a wide spectrum of shapes and colours, press-locked metal brings an aesthetically pleasing and original touch to your creations.

Bins

In order to complete their urban furniture grating range, JK Technic has revolutionised the style of bins. A wide selection of shapes and colours are on offer.

Custom manufacture

JK Technic can manufacture made-to-measure staircases to meet your requirements (layout, size, etc.).

Our research department is available to handle your technical requirements, and can advise you on issues up to and including the realisation of your orders.

T3A and T3B grating

T3A grating

T3A is a press-locked variety of grating (mesh: 30 x 130. Bearing bar: 40 / 3) which has been specially designed for motorways. It can be equipped with a spacing and connecting device on request. 

T3B grating

T3B is an press-welded variety of grating (mesh: 30 x 100. Bearing bar: 40 / 3) which has been specially designed for motorways.

Ladder rungs range

Ladders used in slippery environments require optimal safety conditions, and therefore JK Technic has developed two ranges of ladder rungs that are suitable for this use.

Materials :

  • untreated or galvanised steel,
  • 304 (1.4301) or 316Ti (1.4571) stainless steel
  • aluminium.

Perforations :

  • 12 mm diameter at the top.
  • Custom-made option.

Range with 1 row of holes

Standard length: 2,000 mm.

Width: 25 mm.

Height: 39 mm.

Thickness: 2 mm.

Range with 2 rows of holes

Standard length: 2,000 mm.

Width: 50 mm.

Height: 39 mm.

Thickness: 2 mm.

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)

Portée du caillebotis

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.)

Portée du caillebotis

BEARING BARS (BB)

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

Portée du caillebotis

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...

Portée du caillebotis

RANGE

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

Portée du caillebotis

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.

Portée du caillebotis

SUPPORT BRAKET

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

Serration

 

Portée du caillebotis

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.
