IJM took the opportunity to transform its internal building material operations, such as quarrying and ready-mixed concrete, into a core activity when demand grew significantly outside the Group, setting the foundation for the Group's present Industries Division.

Besides being one of Malaysia's largest quarrying groups, the Industries Division's expansion in steel fabrication plants, scaffolding rentals and the manufacture of prestressed concrete piles business has become a substantial contributor to the Group's activities.

Today, IJM's subsidiaries, Strong Mixed Concrete Sdn. Bhd. has emerged as a niche player in the highly competitive ready-mixed concrete business while Scaffold Master Sdn. Bhd.'s business in scaffolding rentals is the largest in the country.

Malaysian Rock Products is one of Malaysia's largest quarrying groups, with an annual capacity exceeding 6.5 million tons of granite and industrial-use stones. It is the first quarry in Malaysia to be awarded the ISO 9002 certificate for its quality management in aggregate and premix production. Its quarries are located in the Klang Valley, Johor Bahru and Kuantan.


Industrial Concrete Products Berhad, a public listed associate company of the Group, is the country's largest manufacturer of prestressed spun concrete piles. An ISO 9002 certified company, its products are also exported.

Other products manufactured by the Group include HDPE pipes and tanks.
