Publicly listed steel firm PT Krakatau Steel (KRAS) is supplying steel plates for the elevated Jakarta-Cikampek II toll road project.

The state-owned firm will supply 205,000 tons of steel plates, with 28,000 tons in the form of box girders already delivered.

The first placement of box girders -- fabricated by publicly listed Bukaka Teknik Utama using Krakatau Steel plates – was implemented at the construction site at Jakarta-Cikampek KM 46 on Tuesday.

"The use of box girders [instead of precast] require fewer supporting poles. It will speed up construction of the toll road," KRAS market research and development manager Anang Syahroni said in a statement.

The elevated Jakarta-Cikampek II toll road is being constructed to ease traffic on the Jakarta-Cikampek I toll road, which connects the capital to industrial areas in West Java.

Compared to precast, box girders are 12 times stronger and more flexible and recyclable, the firm claims. (bbn)
