electroplating for container house frame corner

today let me introduce anti rusted treatment of our container frame

the beam and columns are made by galvanized steel,and do extra powder coating,so it is hard to get rusted.

but for the container corner,because it is welded by steel plate,although other supplier did powder coating on it,the powder coating can not cover some welding points,it will get rusted in half a year

we do electroplating for the container corner firstly,and then do powder coating,so the container corner will not get rusted

below is picture of our container frame
