Coated Steel Storage Tanks
Steel Products
Epoxy powder coated mild steel is a robust
material, with excellent resistance to impact. A
highly resistant polyurethane sealant ensures that
the tank effectively holds more aggressive
content, such as raw sewage and industrial
effluent to a ph level between 2 13.
Plates for these tanks are prepared using a two
coat, two fire process, ensuring a pin-hole free
coating, tested at 1000v. This makes each panel
highly resilient to surface damage.
A full range of ancillary products including roofs,
ladders, platform etc.are available for this product.

The plates are prepared using a two coat / two fire process, with the first coat internally
and externally being epoxy powder, and the second coat being epoxy powder internally
and polyester externally. The external polyester top coat is then applied to UV to stabilise
the epoxy powder, and to give the required colour to the tank.
The coating is applied electro-statically, ensuring 100% panel coverage, inclusive of bolt
holes and panel edges. The first coat is then semi-cured at 160°C. This provides a good
key for the second coat. The second coat is then applied with this being fully cured at
180°C. Each plate is then tested before leaving the factory using a 1000V spark test to
guarantee a 100% pin hole free surface.
Each plate has a minimum coating thickness of 120 microns per side (240 microns total).
