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 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.
