Even after 95 years, Woelm GmbH in Heiligenhaus, North Rhine-Westphalia, is a medium-sized family business that has made a name for itself in the construction industry with its HELM and KWS brands. It merged from two family businesses in 2005 to become an internationally active company. Today, 280 employees work at Woelm GmbH and produce, among other things, HELM sliding door fittings that meet the highest standards. These fittings are well thought-out solutions for modern residential and commercial construction. These include sliding systems for doors made of wood and glass, heavy sliding gates, sliding shutters, cantilevered entrance gates or curtains in industry or theatres.

In the do-it-yourself sector, HELM sliding gate fittings made of steel are available in various material thicknesses, lengths and slot thicknesses. Special series have been developed for straight-running sliding gates. With the HELM 100 to HELM 700 profile series, the company offers homeowners a comprehensive range up to 2,000 kg sash weight. These can be used for both single and double-pair and manual as well as electric gates. The fittings are made of high-quality solid steel. The surface is additionally galvanised to prevent corrosion. Woelm is constantly developing new products and improving existing solutions. To accommodate customers even more, modular hardware systems have been developed that can be assembled according to requirements and type of use. In addition to the fittings, the company's portfolio also includes numerous accessories such as roller units.
