Kotniz

Quality comes from the hands that work

passionately over the years.

Sebastian Nietupski, General Director

Our success comes not only from new

technologies - it comes mainly from our people.

Zdzisław Nietupski, Founder of Kotniz

The idea for the company originated many years ago in response to the needs of the emerging market of motor boats and yachts in Poland, and the demand for stainless steel and aluminium elements required for the construction of floating vessels.

Highest quality has always been our policy, expressed by hand polished surfaces, attractive prices, "just in time" production, flexible cooperation and best possible service.

For more than 30 years KOTNIZ, the leading supplier for the yacht industry in Poland and in Europe, has been expanding its client base which includes the largest and most notable European shipyards.

We are looking forward to working with you.

We produce all kinds of metal elements from steel and aluminium, present on sail and motor boats, for orders from shipyards and individual clients.

We produce the finest quality yacht steering wheels made of acid-resistant 316L (1.4404) steel. Our offer includes the following diameters of steering wheels: 800 mm, 900 mm, 1000 mm, 1100 mm, 1200 mm.

The steering wheels can also be covered with water-resistant leather in a variety of colours.

Other product

Furthermore, we are able to make other elements out of acid-resistant steel (such as rails, grips, etc.) for sailing and motor boats which may be stitched with waterproof leather according to our customers' orders.

Laser cutting

We own two lasers BYSTRONIC ByAutonom with a power of 4400 W and new BYSTRONIC Bystar II with a power of 6000W. It allows fast cutting of any shape with a good precision (0.1 mm) and guarantees high quality of our products. Laser-cut details have smooth edges that usually do not need any further processing.

Sheet bending

Kotniz offers sheet bending services using modern press brakes by EHT and BYSTRONIC.

Tube bending

Multi-radius, numerically controlled tube bending machines by RASI and MACRI make it possible to bend products consisting of straight sections, arches and spirals in three dimension. It is also possible to bend pipes with a constant (mandrel bending) and changing radius (roll bending) in a single work cycle. The machinery also supports loading 3D geometry in the IGES format. Thanks to the patented MINIMES system, the bending machine ensures high bending repeatability.

technical description

Kotniz was established by Zdzis?aw Nietupski in 1978. Its initial activities revolved around designing and installing utilities and gas systems. In 1984 it started producing steel central heating boilers using natural gas and heating oil as fuel. In 186 it began producing electronic controllers managing the heating of premises with its boilers.

In 1988 Kotniz started the additional production of motor boat and sailboat accessories made from acid-resistant steel. This is currently its main scope of business. Its clients include private individuals, shipyards, and partners from France, Germany, and other European countries. Today the company is run by Sebastian Nietupski (the founder's son).
