We've used Imperial World Trade's drum mixers and some castable products for various construction purposes. Their deals are always professional and it is a trustworthy company to work with. We never have to worry regarding their delivery timings. The quality of services and products are awesome. Their customer service department is also pretty good and very loyal to us and always available for questions and updating us with their latest product. I would highly recommend castables and drum mixers supplied by Imperial World Trade.
