Company history

Kovona Karviná started the production of glass‑fibre laminates in 1953 as one of the first companies in East and Central Europe. At the beginning it focused on special products for military applications (e.g. additional tanks for jet planes) and high-strength helmets for motorcyclists and miners. Fabrication of the first composite components – both for special racing and stock cars – and for trailer caravans is also documented.

In 1970 winding units for precision winding of laminate pipes of up to 3,600 mm diameter were purchased. This technology enabled production of various laminate piping and large-volume tanks and, most importantly, the initiation of environment-oriented manufacture of products for waste water treatment plants designed for small contamination sources. In 1990’s manufacture of laminate products for power plants and chemical industry was started.
