The 'Macalloy Bar' was first launched within the construction industry in 1948 as the worlds first post tensioning bar. It was developed initially for use in prestressed and post tensioned concrete construction. The benefits of using the Macalloy bar have been widely recognised across the construction industry and is now used extensively for wind turbine projects.

High Strength Bolt with Excellent Fatigue Properties
The Macalloy bar provides a high strength steel bar with excellent fatigue properties ideally suited to be used as wind turbine anchor bolts in anchor bolt cages in onshore concrete gravity based foundations.

The Macalloy bar provides technical advantages over the standard 8.8 and 10.9 bolts currently used and can provide significant cost savings.
