A Pakistan's customer inquirythe price of round steel bar.in this order he only mentioned the product's type. I am convinced that he was just the person who only want to know our product's price. so I send the technical information on the model together with the catalog and price list for him.the I didn't expect next day he repllied that he accepted my offer on the terms suggested.he wanted 300t round steel bar and suggested the products arrive in 30 days. from this story ,i understand we must treat every order seriously,and the better after-sale serve can bring the long-time cooperation.
