For 1000mm x 1000m metric tanks, we use the following thickness:

Bottom Tier (Base panel) = 5mm

1st Wall Tier = 5mm

2nd Wall Tier = 5mm

3rd Wall Tier = 5mm

4th Wall Tier = 5mm

Roof Panels = 2mm

 

For  1220mm x 1220mm imperial tanks, we use the following thickness:

Bottom Tier (Base panel) = 5mm (6mm for 4880mm height tanks)

1st Wall Tier = 5mm

2nd Wall Tier = 5mm

3rd Wall Tier = 5mm

4th Wall Tier = 5mm

Roof Panels = 2mm

 

Our steel plate nominal thickness is measured BEFORE galvanising.

 

We do not use 4.7mm (nominal) steel plates, galvanise it and pass it off to our clients as 5mm plates without their knowledge.
