Tank Fabrication Made Easier with Twin Wall PE & PP Sheets

Tank fabrication made easier with TWIN WALL Polyethylene and Polypropylene Sheets

Simona® Twin Wall Sheets are now available in Australia making the construction of PE & PP tanks and similar structures much easier and efficient. They are now available in 2000x1000x40mm from Allplastics Engineering.

The Twin Wall Sheets combine exceptional rigidity, low specific weight and good thermal insulation with the obvious benefits of time saving in the fabrication and machining processes.


PE 100 is impact resistant down to -50°C, weather resistant, and offers a high level of chemical resistance. It is the preferred material for outdoor use. PP Alpha Plus has a service temperature range of 0°C to +100°C, and offers decent insulation properties next to good weldability. It is a top choice for indoor use. PPs feature B1 low flammability following DIN 4102 and are primarily used in ventilation system construction.


PE: 40mm x 1000mm x 4000 mm
PP: 40mm x 1000mm x 4000 mm
