Sheet Pile Tie Bars > Macalloy 17MHS

Upgraded - Macalloy 17MHS 460 to 17MHS 520
Macalloy have recently updated their marine tie-bar system from 17MHS 460 to 17MHS 520.

The M520 is approximately 14% stronger than the traditional Grade 460, and will in some cases allow a smaller diameter bar to be used, thus offering significant savings.

The 17MHS 460 is still available until further notice.

Below is the Tendon Capabilities showing the increased yield loads.

Steelcom sells and distribute Macalloy sheet pile tie bars in Australia and New Zealand.

For inquiries, contact our Sales at 02 9409 1777 or 02 4966 0688.

Steelcom sell Macalloy 17MHS sheet pile tie bars. The 17MHS tie bars have been used in some of the most prestigious steel sheet piling projects in the world for over 45 years.

Macalloy 17MHS is a high strength weldable steel used as the standard bar for tie bars.

A wide range of compatible end connections and fittings have been developed to complement the range of bar diameters from M42 to M100 (smaller diameters are available on request).

Building on the success of the now standard 460 yield of the 17MHS grade tie bar, M105 rolled threads are now available, combined with the special to order 17MHS 500 grade material we can now provide a tie bar with a massive 3825 kN. yield load.
