We make products individually for the needs of the customer, as well as prototypes – including oversized constructions, containing unusual solutions mainly for the US and EU markets.

We have approvals in accordance with the needs and requirements of profile manufacturers and other system materials, including fittings included in the structure. In addition, we are at the stage of implementing the ISO 9001 quality management system.

Promar Steel has been creating windows, doors made of steel, brass, cortene and other materials for over 20 years. Production 15 done manually, but using the latest available technology. This combination allows us to obtain the highest possible precision.

The products are made to individual customer orders and are assembled in luxury, historical and facilities

See how we changed over the years

Pierwszy Anglik


The first Englishman appeared at PROMAR on a foggy morning, November 2nd, 1998. That day we started the production of steel windows in Poland. The first steel windows left the production hall at noon. After visual inspection and measurements of the anti-corrosive coating and preliminary tests, the windows were found to be compliant with the British Standard BS 6510. The high quality of the paint coatings and the accuracy of the assembly only confirmed the high qualifications of the company’s employees. Productivity increased with acquired experience. The ambition was to match the best.

Fragment artykułu Panorama Leszczyńska:


Excerpt from the article Panorama Leszczyńska: According to Kazimierz Dymek, out of a dozen or so thousands of windows sent to the British, complaints concerned only 2 or 3 pieces. The number of orders was systematically increasing, and more and more modern machines appeared in the production hall. Windows for London institutions sometimes have a size of 3 x 2 m, or a total of 6 square meters. With such production – when ultimate accuracy is required – the professionalism of the welder and locksmith plays an essential role. Recently, the windows have been installed in a newly built office building near London docks.

2001 – 2007

Our company’s products went to the British market – attractive, but demanding in terms of quality and design. During this period, we were steadily increasing exports to England, acquiring new contractors and implementing subsequent successful investments in the field of window woodwork together with contractors.


The company changed its legal form and name to the Promar Steel brand still used today. 

In 2008 we launched the production of steel windows and doors in a new plant in Siedlnica. The product range has been expanded to include windows made of stainless steel and bronze.

We started implementing the “in the house” production concept, which assumes a quality policy based on the fact that the entire production process takes place within one production plant, and no window element ever leaves the company and is fully implemented inside our machine park. This is done in order to increase quality and full control over the production process. In connection with the implementation of this concept, the production line was equipped with a powder paint shop.



We opened a new office building. The company’s management, design department, valuation department, sales and export department as well as administration were located in the building.
