Berndorf Band is one of the world’s leading manufacturers of high quality transport and process belts.

When processing chemicals or producing casted films and foils the excellent quality of a Berndorf Band special steel belt is shown in every detail, such as mechanical, physical or geometric properties. Highest corrosion resistance goes without saying. A special process developed by Berndorf Band guarantees perfect adhesion of vee-ropes. The belts are characterized by perfect flatness and dimensional stability as well as by their straight tracking.

Due to these properties Berndorf Band special steel belts represent the perfect component for the chemical industry.

Tradition coupled with innovation and our principle of manufacturing high quality products are the basis of our maxim “continuous reliability”; high quality final products, increased equipment availability and an extended lifetime of your steel belts are the result.

Berndorf Band. Your benefit is based on more than 70 years experience in development and production of endless steel belts.

Vee-ropes and product retaining strips

Both, process and transport belts, can be provided with vee-ropes and/or product retaining strips. Berndorf Band guarantees perfect adhesion of vee-ropes and product retaining strips within a wide range of operating temperatures. This makes Berndorf Band steel belts to an excellent base for chemicals.

Material of vee-ropes

Natural or nitrile rubber (standard) for operating temperatures from -20°C up to +100°C
Natural rubber for operating temperatures from -60°C up to +60°C
Spiral vee-rope made of stainless steel for operating temperatures exceeding +100°C
Nitrile rubber for operating temperatures from -20°C up to +100°C

Material of product retaining strips

Spiral vee rope Standard profiles
Natural rubber for operating temperatures from -60°C up to +60°C
Silicone rubber for operating temperatures from -80°C up to +200°C
