Our Range

Rectangular GRP Sectional Panel Tanks

The Allied Sectional Panel Tanks cover a range of sizes from 1,000 litres to 1,000,000 litres in almost any size configuration. A variety of options such as tank divisions, panel insulation, anti-vortex assemblies, raised ball valve hatches, internal/external bolted, ladders and fittings/valves are offered as appropriate to complete the package.


All materials used in the production and assembly of GRP tanks are rigorously tested for potable water compatibility. This includes long term material performance and mechanical properties, non-metallic components, adhesives, etc. Combined, this analysis forms the basis of the extensive QC procedures.


Allied Pumps’ Sectional Tank tank panels are hot press moulded in glass reinforced plastics (GRP) using isophthalic unsaturated polyester resins and electrical glassfibre reinforcement. The panels are moulded at temperatures up to 150ºC under strict quality control disciplines. The process results in strong, consistent panels which are fully cured, dimensionally accurate with sharply defined profiles and smooth surfaces on both faces. Drilling and finishing of the panels is undertaken in a purpose built controlled area, where high technology automated drilling equipment is used to complete production to exacting tolerance levels.
