In the past few year, A-ONE ALLOY help 3 customers from EU and US to reduce their material cost by 20%+. It all because we make very strict control of the production process and thus the production efficency is improved. Of course, even the labour cost is keep raising, it is relative low comparing to it of EU&US.


For the packing, either in coil or in reel is acceptable per the customer requirement.
