Material Comparisons
Specific Densities:
Pure water equals 1kg per litre
1000 litres of water equals 1 Cubic metre = 1000kgs or 1 Metric tonne
Therefore the specific density of water is 1
The specific density of all metals are measured against this
SD of Stainless Steel = 7.65 7.65 tonne per cubic metre (m3)
To build an 8000L tank of the same dimensions using the same configuration for baffles excreta we would require 10 sheets
The fabrication times for these products are fairly close although plastic and aluminum being much lighter require less handling. Cutting, welding and finish work are much the same except for steel which requires some form of protective coating.
Comparing the finished tank weight based on 10 sheets
| Material |
Tank Weight |
| Aluminum 5mm |
576 kg |
| Steel (mild) 4mm |
1400 kg |
| Stainless Steel 3mm |
1032 kg |
| Plaztuff™ 12mm |
513 kg |
When compared with Plaztuff™:
Aluminum will corrode is prone to dissimilar metal corrosion and electrolysis
Stainless Steel is prone to dissimilar metal corrosion is twice the weight
Steel needs protective coatings , it will still rust and is almost three times the weight
Plaztuff™ can be specified to your customer's exact requirements Colour, UV Stabilizers, fire retardants and chemical inhibitors can be added to create product specific to its environment
Plaztuff™ does not Rust, Rot, Corrode, get osmosis or electrolysis and will handle a wide range of chemicals and fuel oils.
When welded Plaztuff™ will not lost a grade, change its properties in any way shape or form and will not expose the material to rust or corrosion
Plaztuff™ is easily worked with a wide range of tools and machinery, can be machined, tapped and routed
Plaztuff™ has very good engineering properties when compared to rotary molded Medium Density Polyethylene
Plaztuff™ is FDA specified as a food grade material and can be specified for use as a fuel grade material
