Product Advantages of PP Rainwater Modules
1.Flexible Design
They can be combined with multiple modules to form a storage tank and can be freely configured according to site conditions without being restricted by space.
2.Long Service Life
The rainwater modules feature strong environmental adaptability, including anti-aging, corrosion resistance, and resistance to high and low temperatures.
3.Large Module for Easy Construction & Short Construction Period
The modules are connected by interlocking assembly, with simple construction and no need for large machinery. They can be assembled on site, enabling excavation and backfilling on the same day. Construction efficiency is 36% higher than that of 800×800mm modules.
4.Convenient Transportation
Split-type design allows folded storage and transportation of modules, saving valuable transportation space and cost.
5.Higher Bearing Capacity
The PP rainwater modules adopt a hollow-out design supported by 16 columns, maximizing vertical load-bearing capacity. The actual measured load capacity of large modules exceeds 40 tons.
