fortrified. To increase safety level, the inner parts of the outside plates are usually equipped with impact bars. The
outside plates and inside plates are connected by flanging, adhesion, seam welding and so on. Depending on
different bearing capabilities, the outside plates should be light and the inside plates should have higher rigidity
and be able to stand stronger impact.
