Custom Tanks

Tank Liners

and Bunding

We pride ourselves on the standard and quality of the end product delivered to our clients

Wide Bay Plastics have the ability to custom build containers for the specific needs of a huge array of industries and can assist with design and material selections to achieve the desired end result. 

Our custom tanks, tank liners, storage vessels and bunding are fabricated in Polypropylene, Polyethylene or rigid PVC depending on the purpose and chemicals.  We also offer a repair service to existing tanks      (roto-moulded or fabricated) - dependant upon the tank.

Why use Plastic as an alternative to aluminium, mild steel, fibreglass and stainless steel?  Compared to the aforementioned materials, plastics offer better flexibility and have an excellent chemical resistance in corrosive environments where volatile acids, aggressive degreasing agents or solvents may be used.     

We are able to construct stand alone tanks and containers or install liners to existing stainless steel or metal tanks (to extend the life of the existing tank).    If treated correctly, our tanks or liners will be there for a minimum of 15 years.   There are some tanks that were built by our senior tradesman over 25 years ago that are still in use at a powder-coating plant.

We comply with the Australian Standard AU/NZ 4130 and have set procedures for constructing and welding to ensure that the completed product is structurally safe.  We follow certified procedures that have been devised from not just training but over 45 years of experience.   Our senior tradesman was one of the first fabricators in Australia to use an extrusion welding gun and commenced hot air welding in 1978 so our welding techniques have been created with hands-on experience and not just at a 4 day course.  

When designing tanks, vessels or containers our policy is to “overspec” to ensure there is minimal sidewall and material deflection - if any.   During fabrication and prior to leaving our workshop, all tanks are hydro and electronically spark tested.

Some previous projects have been: 

  • Grey water, black water and drinking water tanks to suit RV’s, buses, trucks etc
  • Acid dipping and chrome-plating tanks – stand alone
