Kovinc d. o. o. is a family manufacture and service company. The beginning of the company dates back to 1989, when Pavel Žvelc started producing wrought Kropa lamps and ironmongery work. The volume of production started to grow and the production programme was gradually supplemented. In 1990 we built a new hall and bought new machinery. We targeted our production towards manufacture of various metal products for the needs of builders’ joinery and light metal constructions. In 2001 the founder’ son, Damjan Žvelc took over the company. At first, he operated a Sole Trader business, but in 2005 a limited liability company Kovinc d. o. o. was established.

We are noticing a growth in operation of the company. Currently we sell the majority of products and services in the domestic market. We also started increasing sales in the foreign markets.

We are specialised for three basic production programmes:

metal interior equipment programme
light metal constructions programme
programme of products for complete graphic image of buildings

We also offer a wide range of services for modification the sheet metal and profiles on the state-of-the-art CMC machines. We constantly follow the technological progress and upgrade our production. We offer products and services, such as constructing, advising and on site installation to our customers. We obtained an international certificate for welding according to ISO 3834 standard.
