Frequently asked questions

Is this a firm price?

No. It is an estimate ex GST for the tank on screen. Send it to us with the form below and we will confirm the price, freight and lead time.

What sizes does the calculator cover?

Rectangular and square tanks up to 4,000 mm long, 2,500 mm wide and 1,600 mm deep, and up to 10,000 L. For anything bigger, round, sloped or cone-bottom, send us your drawing.

How thick are the walls?

We choose the wall from how deep the tank is: 6 mm up to 400 mm deep, then 10, 12, 15, 20 and 25 mm as it gets deeper. The estimate already includes it, along with any baffles your size needs.

Where do the fittings go?

Choose the side, then measure from the left edge of that side (looking at it from outside) and up from the base, to the centre of the hole. Holes are kept clear of the corners and the baffle welds.
