Standard manufacturing method
JK technic's pressed gratings are manufactured using techniques that allow for a top quality production (NF EN ISO 14 122-2 regulations).
The material generally used to manufacture open floor gratings is steel (S 235 JR). During the manufacturing process the bearing bars are inserted into the transverse bars. The product thus obtained can be hot-galvanised, in compliance with EN ISO 1461 regulations.
Single or double serrations available
customised products (heavy gratings, etc...)
T or plain framing
Maximum dimensions
. Bearing bar: 3000 mm maxi
. Transverse bar: 2000 mm maxi
Cross section of the bearing bars
. Height of the bearing bar: 20 to 150 mm.
. Thickness of the bearing bar: 2 to 8 mm.
Mesh's base
The base comprised in the space among the bearing bars and the transverse bars, as well as the thickness of both the bearing and the transverse bars, represents the aperture size.
Compliance with the relevant regulations and the weights to be respected are taken into account when defining a base.
Thickness of the BBs: 2 and 3 mm
. The base of the BBs is generally a multiple of 11
. The base of the TBs is generally a multiple of 11.1 Thickness of the BBs: 4 and 5 mm
. The base of the BBs is generally a multiple of 18
. The base of the TBs is generally a multiple of 17
