Rails, uprights and baskets are made of simple and changeable unclosed profiles manufactured from 0.078inch sheet steel (sheet stainless steel is optional).
The frame corners are manufactured with new-designed joints welded to uprights and rails for roof and bottom. Only 8 resistance screws are needed to mount the structures while position pins allow the easy mounting.
