Secure your greenhouse cladding with industrial-grade spring lock wire. Engineered from 2mm high-manganese (Mn) steel and finished with a protective black polymer coating, our lock wire delivers superior clamping force inside standard C-profile aluminum or steel lock channels.
Trusted by commercial growers across North America, Australia, and Japan, this system ensures your polyethylene film stays taut and secure—even in extreme weather conditions.
Key Advantages & Features
Exceptional Wind Resistance: Engineered from high-tensile Mn spring steel, the wire locks firmly into the C-channel without popping loose under pressure. Designed to withstand extreme wind loads up to Beaufort Scale 9 (strong gales up to 50 mph / 80 km/h).
All-Weather & UV Durability: The outer polymer coating shields the underlying steel from severe temperature fluctuations, rust, and degradation caused by intense UV exposure.
High Elasticity & Reusability: Unlike standard iron or low-grade steel wires that deform after initial installation, our high-manganese steel retains its original shape across multiple crop seasons and film replacements.
Film & Installer Protection: The smooth, rounded black coating prevents friction tears or chemical corrosion on poly films, while also protecting installation crews from sharp edges during setup.
