Polyline Industries design and fabricate primary ventilation products for underground mining. Durable and quality made ventilation systems are paramount are they provide a controlled flow of air to the underground workings of a mine site.

Ventilation products fabricated from High-Density Polyethylene (HDPE) are superior to their steel and aluminium counterparts.

Why Choose Polyline's Primary Ventilation?

HDPE is UV stable with a lifespan of 15+ years. It is excellent in damp and salty environments as it does not rust or corrode – making it a superior option to steel

As polymers are long chain molecules they give plastics a memory resulting in high impact unlike steel or aluminium that dent on impact

Enables installation/removal an easier task to perform, especially in tight spaces

Products are designed specifically for ease of transport and to reduce shipping costs
