Introduction : Customer provide us some information about their market: color preference, geographical position, the climate. They pay more attention to the feature of UV proof and hardware quality. Focusing on customer’s requirements, we do a lot of work: make the sample colors for customer’s confirmation, and recommend the models, sizes according to our experience, searching for the SS304 handles which they demand. They started with a 40HQ container. The price is a little higher than standard doors, but quality is satisfied. Gradually, the order volume reaches 1 million us dollars per year.
