System SiGMA-LI PP-R
System SiGMA-LI PP-R System SiGMA-LI Premium Nowość

SiGMA-Li is the highest quality confirmed by numerous distributors and installers from Poland and abroad

Jesteśmy polskim producentem

We are a Polish manufacturer

We are a company with Polish capital and all our products are manufactured in Poland, namely in our production plant in Goleszów, Silesian Province.

Sami produkujemy dwa kompletne systemy instalacyjne

We manufacture two complete installation systems ourselves

Since 1995, we have been manufacturing the PP-R SiGMA-Li polypropylene welded system, and since 2013 also a system dedicated to SiGMA-Li Premium radiator and surface central heating installations. Taking care of the comprehensiveness of our offer, we manufacture all necessary, and even smallest components, of the installations ourselves.

Oferujemy Europejską jakość w polskiej cenie

We offer a European quality at Polish prices

Our products meet the highest European quality standards and stand out with a very competitive price. Automation in production, long-standing experience and the fact of manufacturing the entire range of products in Poland, allow us to provide attractive prices. The competitive products come mainly from Western Europe, which generates high logistics costs and reflects in a higher price of the product.

Wprowadzamy innowacyjne rozwiązania

We introduce innovative solutions

In the manufacturing process of individual elements of installation systems, we use advanced technologies and high quality materials. Thanks to this, we introduce innovative solutions on the Polish market, such as those used in the SiGMA-Li Premium system:

  • Brass manifoldswhich, unlike most of alternative products, are nickel-plated both inside and outside.
  • PP-GF manifolds - an absolute novelty in Poland!
  • Cabinets for manifolds - made of 100% galvanized steel.
