A17-57 circular column formwork supporting wood, plywood is converted into steel support how to convert?
When the structural column bamboo plywood template steel support and the construction column composite steel plate steel support exchange, you have to be marked in the back, after all, these two are not the same.
Item number is different, but there is one thing you have to pay attention to.
Pro, I would like to ask you what is the norm of the quota is your local?
