We are experts in high-frequency welding, which is the absolute strongest production technology for waterproof workwear in PU – because with high-frequency welding you achieve a joint that is as strong as the material itself. The result is PU products with a high water column pressure of 10,000 mm – with both waterproof fabric and waterproof seams.

This is one of the reasons why ELKA PRO is the best waterproof clothing for cleaning.
