STAUFF Mounting Rail (Type STSV – Heavy Series)
The STAUFF Mounting Rail (Type STSV – Heavy Series) is designed in strict accordance with DIN 3015, Part 2. Used in combination with Type GMV nuts, it ensures stable fastening for STAUFF Groups 3S to 6S. Available in standard lengths of 1 m and 2 m, it is manufactured from materials ranging from carbon steel, either uncoated or blue chromated zinc-plated, to high-strength V4A stainless steel. The available product codes are: STSV-1M-W1, STSV-2M-W1, STSV-1M-W32, STSV-2M-W32, STSV-1M-W5, STSV-2M-W5.
The STAUFF Mounting Rail (Type STSV – Heavy Series) is the fundamental structural fastening component used in the construction of industrial systems. Designed in strict compliance with DIN 3015, Part 2, this profile is intended for the demanding applications typical of the Heavy Series. The rail is developed for use in combination with the Type GMV mounting rail nut, ensuring optimal mechanical retention. The system is specifically compatible with STAUFF Groups 3S, 4S, 5S and 6S, which correspond exactly to DIN Groups 1, 2, 3 and 4.
The rail profile maintains constant cross-sectional dimensions to ensure maximum technical uniformity during installation: the width of the lower base (dimension B1) is 40 mm, the width of the upper opening (dimension B2) is 13 mm, the overall profile height (dimension H) is 22 mm and the material thickness (dimension S) is 5 mm. The standard catalogue supply lengths include 1-metre sections, equivalent to 3.28 ft and identified by code 1M, and 2-metre sections, equivalent to 6.56 ft and identified by code 2M. The manufacturer also states that alternative lengths are available upon request to accommodate non-standard system layouts.
The availability of different construction material options allows the rail to be used in a wide range of environmental and application conditions. Material code W1 indicates uncoated carbon steel, ideal for installations involving direct welding. Code W32 identifies zinc-plated, blue-chromated carbon steel, providing additional surface protection against oxidation. For sectors requiring maximum chemical and corrosion resistance, the W5 variant is available, manufactured entirely from V4A stainless steel, specifically grades 1.4401 and 1.4571, corresponding to AISI 316 and AISI 316 Ti. Additional materials and different surface finishes are available upon request to meet specific technical requirements.
