The main function of the roof downpipe is to concentrate the rainwater on the roof to a place,
and then use the pipes and pipe holes to timely discharge the rainwater to the downpipe.
The function of the roof drain pipe is to prevent the rainwater from accumulating on the roof
after the water pipe is blocked, which causes the roof to be overloaded and affects the structural safety.
At the same time, it also reduces the probability that the roof will increase the leakage due to the accumulation of water.
so the main use of downspout is to Collect roof rainwater and concentrate it on the rainwater pipes laid below the ground

No matter the round pipe or square pipe, it's empty inside. Normally, the roll forming rollers will be outside,
so how to ensure the pipe in a perfect shape as what we want?
We have the solution like this: have one mandril inside the pipe when forming, and there are lot of auxiliary rollers on the mandril.
The auxiliary rollers can hold and carry the material inside, incase the forming rollers press much outside and make the pipe deformed.
