BMP Slope Protection
TECCO® Mesh G45/2 is a high-tensile steel wire mesh system designed to protect against rockfall and slope instability. Engineers widely use this mesh in geotechnical applications to safeguard areas prone to natural hazards such as landslides, avalanches, and mudflows. With its exceptional strength, durability, and resistance to corrosion, TECCO Mesh G45/2 guarantees long-term performance in challenging environments.
Key Benefits
High Tensile Strength: The mesh offers a tensile strength of ≥ 1,770 N/mm², which helps resist the forces of rockfall and slope movement.
Superior Corrosion Resistance: The mesh features GEOBRUGG SUPERCOATING, a protective layer of 95% Zn and 5% Al. This coating ensures durability in harsh weather and environmental conditions.
Rhomboid Mesh Shape: The mesh’s unique rhomboid shape distributes the load effectively, making it ideal for handling dynamic forces like rockfall.
Customizable Dimensions: The mesh offers flexibility with dimensions, allowing for easy customization to meet specific project requirements.
