technical suport

As we strive together with our customers to achieve defect free "as cast" castings for some of the world's most demanding end-users, we have developed a philosophy of "as cast, not after cast." Working alongside our customers through product innovation, technical backup and consultancy services, coupled with over 100 years of combined in-house practical foundry experience, we strive to supply the best product and technical solution in the market.

Rand York not only offers its customers high quality, competitive products but also a high level of technical support. We have helped many customers with the selection of materials, methods and calculations to aid the production of large steel castings and rolls. We have an in depth experience of foundry practice and would be pleased to offer advice or opinion to any of our customers. In most instances, we do this on site at the customer's facility.

OUR PHILOSOPHY CAN BEST BE DESCRIBED AS:

"AS CAST, NOT AFTER CAST"
