After the new year holiday, we received a speical inquiry about the flanges from one of our customers. They sent us detail drawing and required the flat flanges same as the drawings requirement. We studied the drawings carefully and made the best offer. We calculated and listed the weight and cost according to the drawing provided. The customers were very satified with our quotation, they would not expect such professional quotation, and confirmed the order soon after several discussion on the details. Now the full container ordered flanges have been well finished and shipped out today. If you have any unstandard flanges and look for the manufactuer, we are just here.
