I have never used a business to business web portal before but I really needed a supply of steel products for my small business steel bit company to manufacture enough finished drill bits and tool bits for a shipment order to be sent out before the year was up. I was able to locate a company in China that was able to supply me with the steel products I needed in a short amount of time. While the shipment has not arrived yet I was able to get confirmation just yesterday that may materials had shipped so I look forward to seeing the grade of materials I will be getting my hands on. For now I can say that metdaq.com was very easy to use and navigate.
