Tek-Tanks specialise in the design and manufacture of plastic tank systems using high strength, high density polyethylene (HDPE). Our tanks overcome the persistent corrosion and weight problems of aluminium, mild steel and stainless steel. Our professional team of engineers will guide you through the process of building your custom tank from start to finish.

Custom Tanks

Tek-Tanks custom built tanks are perfectly suited to a wide number of sectors, including marine, automotive, industrial, welfare and domestic. We can produce tanks to hold a wide variety of liquids ranging from toilet waste and fuels to fresh taste free drinking water.


Despite our name, at Tek-Tanks we can do much more than just manufacture quality plastic tanks. We offer a bespoke design and fabrication service to cater for almost any idea that you can think of.
