Overview

A turnkey manufacturing system that replaces traditional steel springs with fibreglass thread and resin, delivering longer life, silent operation and complete corrosion resistance.

Tractive’s composite spring technology replaces traditional steel with advanced fibreglass threads and resin. The patented, turnkey manufacturing system is self-contained, enabling door manufacturers to produce springs in-house and just in time — eliminating reliance on distant foundries.

The result is superior spring performance, reduced failure rates and significantly lower production costs for manufacturers and end users alike.

longer life expectancy: 75%
lighter than steel springs: 33%
