We are delighted to announce the addition of Webnet Duplex to our established range of Webnet stainless steel mesh solutions.
Manufactured from highly corrosion-resistant Duplex stainless steel 1.4462, Webnet Duplex is the perfect solution for projects in particularly aggressive environments – making it the ideal choice for coastal areas, industrial plants, heavily trafficked roads and urban infrastructure. In fact, anywhere with high concentrations of salt, pollutants, acid rain, waste gases etc.
Thanks to the superior strength and corrosion resistance of Duplex steel, Webnet Duplex maintains its structural integrity and visual appeal even in the most demanding conditions.
Built for Harsh Environments
With a range of options, Webnet Duplex excels in even the most challenging environments, such as:
- Coastal areas – where salty air often corrodes unsuitable metals.
- Roads and bridges – which are exposed to de-icing salt and heavy traffic emissions.
- Industrial zones – with airborne pollutants or chemical vapours.
Easy to Work With
Despite its high strength, Webnet Duplex offers the same flexibility as our existing Jakob Webnet systems. Architects can choose from various rope thicknesses and mesh sizes to suit their aesthetic needs, whether it’s a light, almost invisible look or a more-imposing, bold design.
Low Maintenance, Long Life
Webnet Duplex’s exceptional resistance to rust and weathering means minimal maintenance is required post-installation. That saves time and cost, which is especially valuable for installations on tall buildings or in remote or inaccessible locations.
Our established Webnet range in 1.4401 and 1.4404 (AISI 316 and 316L) already meets the needs of most applications. Webnet Duplex goes a step further for sites exposed to salt, pollution or extreme climates, offering improved resistance to pitting, crevice and stress corrosion cracking and helping to reduce maintenance over the service life of the installation.
The Beauty and Versatility of Webnet
With the addition of Webnet Duplex, our Webnet portfolio is perfect for a wide range of applications, including:
- Balustrades and Guardrails
Safe, slim barriers that don’t block views. - Green Walls
A sturdy trellis for climbing plants on buildings. - Building Facades & Screens
