About Us

The RRD group was established in 1983 as an engineering and trading company, servicing the needs of industry. Over years RRD established a reputation as a supplier of quality products at competitive prices. Customers came to know RRD as a company whose skills could be used to solve supply related problems.

From the very beginning the RRD philosophy has been to supply well designed, competitively priced products that meet or exceed the customer’s specifications. In 1998 RRD fulfilled an urgent requirement for metallic expansion joints for one of our customer who was importing the expansion joints. Through experience such as this, and in the absence of a suitable quality manufacturing facility in India, RRD decided to venture into the manufacturing of expansion joints in 1999.

From its small-scale beginnings RRD has grown and diversified. Today we offer a complete range of expansion joint products to our customers. RRD has ongoing involvement with major customers in the power, steel, cement, process and other related industries.
