The history of the LRB Group can be traced back to the establishment of Maju Weko Timber Industries Sdn Bhd (MWTI), known as Leong Yoke Wing Timber Industries Sendirian Berhad, in 1973. MWTI was initially focused on processing and sales of sawn timber. The business later expanded to incorporate kiln drying and treatment of logs, and the manufacturing of wood moulding products. MWTI is the concession holder of approximately 9000 acres of forest reserves in Perak Darul Ridzuan.

Dato’ Leong Wei Kong, the founder, brings with him over 30 years of experience in the timber industry. He has been instrumental in the growth and development of MWTI . In 1980, Abd Aziz bin Jantan joined MWTI as a shareholder. He was instrumental in expanding the upstream activities of the LRB Group particularly in timber harvesting. He has approximately 26 years of experience in the timber industry.

In 1981, SAM was incorporated to focus mainly on timber trading and the transportation of logs and in 1991, MLT was incorporated to do timber harvesting.
