5) Supporting Stand
Basic Support:
- Cage design steel frame of 8 vertical beams of metal stand (2"x2", shell thickness 2mm; traditional stand of 1mm is not recommended).
- 4 no. 3"x2" chengnai beam as reinforcement support. It is extremely important to provided sound support for steel frame for they are hollow, and will be deformed or give way once over stress or rusted due to stress effect.
Each of chengnai beam 3" by 2" solid form can support up to 1 ton in vertical loading.
Overrall, just like the tank need good safety factor (of minimum 3.8 design factor), the stand will need 10.0 as safety factor.
- Water changing inlet
you might notice there is a small hole on the centre of over flow box. The hole is the inlet to water change.
