Bolted Panel Water Tank


RHINO bolted panel liner tanks are of vertical cylinder design, and are of a unique two-part construction , in which the contained water or other liquid never comes in contact with any material that is subject to corrosion.

This construction results in a zero-maintenance or nil- maintenance tank, with a design life of more than 50 years.

The external, cylindrical shell is of ZincAlume steel, having very high corrosion resistance.

Inside the shell is a containment bladder constructed out of a multiple-layer liner material fabricated from polyethylene, with a woven fabric reinforcement layer and a backing layer of Metallocene.

The tanks are available in capacities: 10,000 (10 kl) litres to 2,500,000 (2500 kl)

RHINO bolted panel liner tanks are superior to both RCC tanks (plain or lined) and welded-steel , rubber-lined or epoxy-painted tanks with regard to design life, maintenance, maintenance cost, maintenance downtime, life-cycle cost, re-sale value, residual value and scrap value.

RHINO tanks can replace RCC tanks and welded-steel tanks in most – if not all – applications, and are a very cost-effective substitute.

Material of Construction


Special grade corrosion-resistant BlueScope ZincAlume Steel. (For more details about"BlueScope Steel" please click here. BlueScope.pdf)

Inner Liner

Multi-layer, reinforced, Metallocene-backed pulyethylene sheet. (For more details about "HydraShield Liner" please click here HydraShield.pdf)

Tank Body

Rhino Bolted-Panel Liner tanks have a two-part construction:

  • Outer shell: Constructed of corrugated ZincAlume steel from BlueScope Australia, having four times the life span of GI sheet, and much higher resistance to weather and corrosion

    The shell has multiple layers of ZincAlume sheet, for structural strength. The exact number of layers depends on the height and diameter of the specific tank.

    The corrugated construction increases the hoop stress withstand of the steel sheet, so that less material is needed to achieve the same performance.

    The shell segments are Bolted together with 12 mm hot dip galvanised bults.

  • Inner liner:Multiple-layer, reinforced pulyethylene sheets backed by a layer of high-impact resistant Metallocene. Reinforcement with woven scrim fabric to

    This construction ensures that the liquid/water contents never come into contact with steel shell, to reduce the possibility of internal corrosion to zero.

Tank Roof

Constructed of ZincAlume or GI corrugated sheet, supported over Hot-Dip-Galvanised roof trusses.

Corrosion protection

BlueScope ZincAlume steel has coating of Zincaluminium Alloy, 55% Zinc, 42.5% Aluminium and 2.5 % silicon.

Zinc provides sacrificial protection, Aluminium provides barrier protection, and silicon provides abrasion resistance.

Back-up Corrosion Protection

Protection by the use of sacrificial magnesium anodes.
