Tension Rods - Macalloy 460, S460, 520, S520

Macalloy tension rods are the core component of the Macalloy tension structures range. They provide a high strength threaded steel bar with architectural fork end finish.

Two standard strength systems are available. The Macalloy 460 range with a yield strength of 66,700 psi and Macalloy 520 with a yield strength of 75,400 psi.

Macalloy tension rods are available in a range of finishes including carbon, galvanized and the stainless steel range known as S460 and S520 to denote stainless and the yield strength.

Bars are available with outer thread diameters from 0.39" to 3.94".

The tension rod system, also known globally as tie rods, tie bars and tension bars provide adjustment of the total length. Further adjustment of the bar can be achieved with the use of a turnbuckle, which can also be used to induce a load in the system.

The tension rod system utilises the same Macalloy fork end as the rest of the tension structures range of stainless cables and compression struts allowing for combinations of all 3 systems.

Bars are available in lengths up to 12 metres with longer lengths achievable by connecting bars with couplers or turnbuckles.

A range of crossover and connection solutions are available, particularly applicable for bracing and cross bracing applications.

The Macalloy tension bar system has CE approval, soon to be mandatory for structural steel work throughout the EU.
