Stalfa Sp. z o.o. with its registered office in Sokołów Podlaski was established on June 1, 1995 on the initiative of Mostostal Siedlce S.A. (currently GK Polimex Mostostal.). The company has developed ever since, as evidenced by the investments made in recent years.
In 2005, the production of steel products was separated from galvanised and painted products. It became possible thanks to the investment in a new production area. In 2006, we added aluminium products to our range.
Stalfa Sp. z o.o. operates in the production industry as an independent business partner of steel and aluminium products used in the broadly understood construction industry, including: infrastructure, telecommunications, energy and others. The company’s mission is to produce high-quality products, meet the needs and expectations of the customer as well as increase their satisfaction and willingness to continue cooperation. Our goal is to constantly improve production processes that allow us to manufacture products at competitive prices, while the company’s strategic potential is its employees, who guarantee development and success.
The company makes sure that the production process is safe for both people and the environment, which is why the ISO 9001:2008 Quality Assurance System and the ISO 14001:2004 Environmental Management System have been implemented for the production of light steel structures and structural elements. Stalfa also has the required TUV certificates for welding steel and aluminium. The above certificates are of the greatest importance for the company, because thanks to them, we can safely obtain high-quality steel and aluminium products.
We are proud of the company’s position in the production of steel and aluminium structures, which has been developed jointly by all employees.
