Drossbach Steel Ducting 40mm per metre

Description

Drossbach Steel Ducting 40mm is corrugated steel duct sold per metre. It forms the void for post-tensioning tendons in cast-in-place concrete. The duct is placed in the formwork before the pour, and the tendon is threaded through it and grouted after stressing.

Powerpac stocks matching Drossbach end caps for 40mm ducting, plus grout nipples and a GroutSnout vent cap that suits 40mm and 50mm ducting. Other sizes run from 30mm to 150mm.

Powerpac has not published whether the 40mm figure is the inside or outside diameter, or the wall thickness, for this SKU. Check both against your engineer’s drawings before you order. Tradespeople also call this product post-tension duct or tendon duct.
