Product Use in the Workplace

  • Warehouse - Designed to house large amounts of goods, warehouses always carry a safety risk. High footfall, movement of large objects, machinery and vehicles mean that the warehouse is always a hive of activity. Applying a tough flame retardant coating such as not only extends the lifespan, but also give peace of mind of flame retardancy. 
  • Bridge - Taking tremendous weight and stresses, bridges need to be tough, long-lasting and safe. Imagine a bridge without a flame retardant anti-corrosion coating; that's a whole load of potential for the bridge to fail. Bridges can never fail, it just isn't an option; imagine the majesty of the Forth Railway Bridge in a crumpled heap meshed in between a very unlucky train. Exactly.
