Defense Barriers

Defense Barriers | Welded Mesh Barriers with Geotextile LinerWe supply durable welded mesh defense barriers fitted with 250–350g/m² geotextile liners. Standard wire gauges are 4.0mm, 4.5mm and 5.0mm, paired with various mesh sizes. Available in multiple cell combinations and anti-rust treatments. Simply fill with sand or gravel on site, ideal for emergency flood defence, military protection and temporary site enclosures.

Our defense barriers are foldable welded mesh units equipped with heavy-duty non-woven geotextile liners. On-site filling with sand, soil, gravel or crushed stone creates sturdy protective walls. These products are widely used for military perimeters, temporary checkpoints, flood control and site security.

All units come folded for easy transportation and unfold quickly for installation. The rigid welded mesh maintains shape steadily, while the integrated geotextile liner holds fill materials in place. We adopt hot-dip galvanized wire and Galfan wire as standard materials, paired with UV-stabilized geotextile fabric. You can choose single-cell units or pre-connected multi-cell assemblies.
