DYWIDAG Prestressing Systems using Bars

General

Prestressing bars are hot-rolled, tempered from the rolling heat, stretched and annealed, with a circular cross section. Bars are made of prestressing steel Y 1050 H according to prEN 10138-4.

Threadbars and plain bars are available in mill lengths up 18 m and may be cut to specified lengths before shipment to the jobsite.

Threadbars

Threadbars are available in Ø 17.5, 26.5, 32, 36, 40 and 47 mm. Threadbars feature continuous hot-rolled ribs, thus providing a right-hand thread along the entire length. The threadbar can be cut anywhere and is threadable without further preparation. Threadbars are specified by nominal diameter and their specific WR, e.g. 26 WR.

Plain bars

Plain bars are available in Ø32 and 36 mm. Both ends of a plain bar, which is cut to suit individual project requirements, are provided with special cold-rolled threads. The thread lengths are manufactured in the shop according to project specifications. Plain bars are specified by nominal diameter and their specific WS, e.g. 32 WS.
