Outokumpu wins dowel bar order

Outokumpu Long Products has recently won a contract to provide 350 metric tonnes of smooth round stainless steel dowel bar for the Mega Reservoirs PRPS-3 at Rawdat Rashed (Package D). Habtoor Leighton Group (HLG), contractor for PRPS 3 and Big Blue has made a supplier agreement to use stainless steel dowel bars manufactured by Outokumpu. The bars will be supplied in grade Supra 316L/4404 to be used in the expansion joints for rafts and walls of the reservoirs.

The new mega reservoirs projects will include five primary reservoirs and pumping station (PRPS) packages with a capacity of 100 million gallons each. The objective of the project is to provide seven days’ potable water storage in new reservoirs, combined with the existing and future secondary reservoirs, to preserve Qatar’s water quality.

Outokumpu stainless steel dowel bars are used in expansion joints for the movement of lateral loads and manage stress within the joint. The dowels are debonded and movements allowed by specially designed sleeves by Big Blue which includes uPVC pipe, compressible filler and end cap. The one half of the dowel is embedded into concrete, while the other half is debonded to allow the movement at the expansion joints.
