The thickness of the work surface is the most critical, not only to ensure that the effect is not too thick, but also the price is high, but also the surrounding and ribs. The circumference plays a supporting role in use. The thickness and height are closely related to the platform support ability. For the stretching effect, the height and thickness of the reinforcing ribs should also be designed according to the bearing requirements. The height of the reinforcing ribs is usually half gluten, full ribs and flat ribs.
