Full gratings

JK Technic full gratings can be used for visual ensembles with an identical appearance on both sides of the panel (the cross-bars are of the same dimensions as the bearer bars).

They are mainly used for filling balustrades and making sun-breaker and privacy screens.

Characteristics

Mesh

The mesh spacing is defined in accordance with the standards and loads that must be respected:

  • BB thickness of 2, 3, 4 and 5 mm
  • The BB spacing is typically a multiple of 11.
  • The IB spacing is typically a multiple of 11.1.

Bearer bars and cross-bars

  • Standard heights: 20-140 mm.
  • Standard thickness: 2-9 mm.

Dimensions

  • Maximum length of bearer bars: 4000 mm.
  • Maximum length of spacers: 2000 mm.

Surface treatment

  • Galvanised in accordance with EN ISO 1461 standards.
  • This product may be ordered in 304 & 316 stainless steel
  • This product may be ordered in aluminium.

Finish

  • Available with "flat" edge or without edges
  • Available with single or double notching on request.
  • HALF-MOON or SAWTOOTH notching available.

Finished product

  • Custom manufacture based on the dimensions given by the customer or on plans drawn up by our research department.
  • Plain or galvanised ½ laps, panels and staircase steps can be easily assembled on site.

Assembly

JK Technic press-locked grating is characterized by transverse, cross bars inserted under high pressure into pre-existing notches in the bearing bars. This grating is produced in “flat” or “T”-shaped sections, welded into place and then optionally undergoes hot-dip galvanizing in accordance with the applicable EN ISO 1461 standards. For situations with an increased risk of slipping, anti-slip grating can be produced, where the upper surface of the bearing bars and/or the transverse bars can be given anti-slip serrations. JK Technic press-locked grating is typically manufactured from EN 10025 standard S235JR steel, which ensures a consistent production quality. RAL-GZ 638 manufacturing tolerances applied.

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. 

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...

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.
