Keep an eye on steel prices


Since March 2020 raw material prices for steel and stainless steel production have risen dramatically.

Note steel

Since some steel types are no longer produced in Europe, they need to be imported. The freight costs of € 6000 and more per 40 ft container have also contributed to a sharp increase in price.

You are welcome to contact us for current prices for all heavily commodity based products such as lightning conductors, small coils and rib laths.
