FR Rated Industrial Sock

The AUSTRALIAN manufactured FR RATED INDUSTRIAL SOCK is a unique, comfortable, three layer constructed high-performance garment. The garment was engineered to provide an additional layer of protection for employees working in primary aluminium smelters where molten metal can enter safety footwear or penetrate protective workwear. The garment is however multi-purpose and suitable for any environment where there is risk of injury from electric arc, flash fire, extreme heat and ignition. 

The garment's ability to protect the wearer against injury lies in a unique knitting process. Tightly knitted layers assist in diffusing flame immediately, allowing the garment to resist extreme heat and molten metal to temperatures of 1400⁰C. In such extreme conditions, the garment will not melt and affix to the wearer's body.

About the Wool: Selectively bred in Tasmania with quality, sustainability and provenance.

The Natural Properties of Merino Wool

Wool is one of the oldest known natural fibres and is constantly in demand for its unique natural properties including comfort and inherent fire resistance, properties that science cannot yet replicate. The ability of Wool to absorb 30 percent of its weight in moisture vapour gives it superior comfort, insulation, anti-static properties and flame resistance. While Wool can absorb moisture, it also repels liquids. Wool has a natural elasticity greater than any other natural fibre, which makes it comfortable to wear as it fits the shape of the body.

Australian Merino Wool provides superior benefits for technical clothing: warmth when wet or dry, high absorbency, flame and static resistance, ultra durability, rapid drying, high warmth to weight ratio and eco-friendly manufacturing.

The Nylon Content

The inclusion of a small percentage of Nylon (7%) serves a highly specialised structural purpose. While the majority of the garment relies on the pure flame resistant fibres of Australian Merino Wool to shield wearers against extreme heat and repel molten metal splash, the Nylon content acts as a critical reinforcing framework that guarantees durability, structure and shape retention under harsh conditions.

Industrial environments require protective gear to withstand high friction and frequent washing while maintaining structural integrity. Heavy industrial work boots subject socks to relentless rubbing, particularly at the heel, toe and ball of the foot. While pure Merino Wool fibres have exceptional thermal properties, they can fray and thin out under high-friction stress. Nylon provides superior abrasion resistance, acting as a structural anchor that prevents holes forming and heavily extends operational lifespan.

Industrial safety socks must stay firmly in place: sagging or bunching inside heavy work footwear creates friction points, hot spots and blisters. Nylon possesses high stretch recovery and resilience. This elasticity ensures the garment tightly contours to the foot during movement and snaps back to its original shape after use, keeping the garment secure all day.
