Webnet Duplex: For demanding environments

Jakob Rope Systems is expanding its stainless steel net range with Webnet Duplex, a particularly corrosion-resistant mesh made of duplex steel 1.4462. Ideal for demanding locations such as coastal areas, industrial plants, roads, bridges or desert regions.

With Webnet Duplex, Jakob Rope Systems presents an innovation in the field of stainless steel nets. Based on the proven Webnet system and manufactured from high-quality duplex steel 1.4462, Webnet Duplex sets new standards in corrosion resistance and durability – ideal for use in demanding environments such as coastal and desert regions, industrial plants and urban infrastructures.

Ideal for demanding environments

Whether in extreme climate zones or harsh industrial environments – Webnet Duplex ensures increased durability and safety.

Roads and bridges: High resistance to road salt and exhaust fumes
Coastal structures: Protection from salt water, sea air and high humidity
Industrial and urban areas: Resistant to air pollutants, acid rain and industrial waste gases
Desert regions: High resistance to abrasive sand and extreme temperature fluctuations
Industrial plants in arid regions: Robust against sulfur oxides (SO₂) and other aggressive pollutants in the oil and gas industry

High corrosion resistance for extreme conditions

Thanks to the use of duplex steel 1.4462, Webnet Duplex achieves the increased corrosion resistance class CRC 4. It is more resistant to aggressive environmental influences such as salt water, air pollutants and chemical vapors and is therefore suitable for use in ports, roads, bridges, industrial plants and urban areas with high environmental pollution.

Longer service life, lower maintenance costs

Webnet Duplex impresses with its improved resistance to pitting, crevice and stress corrosion cracking, which significantly reduces maintenance intervals and considerably extends service life. This reduces long-term maintenance costs – a decisive advantage for building owners and planners.

Fast and straightforward availability

Despite the highly resistant duplex steel, the delivery time remains identical to our other Webnet systems. There are no additional waiting times or expenses for our customers. This allows construction projects to be planned and realized efficiently.

Jakob Engineering and production for the highest quality

We manufacture and assemble Webnet Duplex completely ourselves. This guarantees consistently high quality standards and precise workmanship, which is essential for safe and long-term use.

Our engineering department supports customers with dimensioning and statics. We supply Webnet Duplex ex works for every project. We can also carry out installation and testing on request. Our expertise in all areas of the process chain enables the rapid and high-quality implementation of construction projects.

Versatile designs for individual requirements

Webnet Duplex is available in a variety of versions and offers all the properties and possibilities of the tried and tested Webnet – but with the decisive improvement of increased corrosion resistance.

Rope diameter: Available in 1.5 mm, 2 mm and 3 mm
Design: Options for sleeveless or with sleeves
Flexibility: The selection of mesh angles, mesh sizes and edge formations corresponds to the other Webnet systems and offers many possibilities for a wide range of applications.
