Open floor bearing plate and closed floor bearing plate processing fees are different, Opening LouCheng board and held their LouCheng plate in the aspects of the advantages and disadvantages, opening LouCheng plate processing, because of its type plate shape is open when processing so directly to the board stacked together, speed up the production speed, directly with the finished products produced by the pile of put, convenient packaging do not take a place, on the contrary silent bearing version is due to its special silent type plate production cannot be finished product stack Up, the processing speed is significantly lower than the open floor bearing plate, the closed load-bearing version of the packaging difficulty is greater than the open floor bearing plate, and the most critical point, because the closed floor bearing plate can not be a pile up, so it takes up more space than the open floor bearing plate. So just look at the advantages and disadvantages of the open floor bearing plate and the closed floor bearing plate can be very clear why the open floor bearing plate and the closed floor bearing plate processing fees are different.
Open floor bearing plate and closed floor bearing plate freight is different due to open floor bearing plate and closed floor bearing plate space size is not the same, the same number of meters, open floor bearing plate to find the car will be smaller than the closed load-bearing version of the car, the freight will naturally be much lower.
