Macalloy 460 Stainless

In keeping with Macalloy's position as the international leader for tension structure supplies, Stainless Macalloy S460 has now been developed.

Macalloy Grade S460 provides a unique opportunity to present the same shape and profile for all bar systems. Many more structures are moving to stainless steel tension support systems.

Buildings and their facades are all different and each requires an individual approach. Decon engineers are experienced at recognising the opportunities to stretch the design envelope, to provide a truly individual solution for your project.

Macalloy S460 is selected from high strength stainless steel to provide the optimum balance of strength, ductility and appearance.

The standard left hand–right hand tendon will provide adjustment to accommodate site tolerances:

  • Cutting tolerance for rods up to M56 (2-1/4") +/- 6 mm (1/4")
  • Adjustment for rods up to M10 (3/8") +/- 12 mm (1/2") each end
  • Adjustment for rods M12 (1/2") to M56 (2-1/4") +/- 1/2 diameter each end
  • Adjustment for all rods with a turnbuckle +/- 50 mm (2")

All standard Macalloy S460 rods are finished with a light satin finish approximately equal to an N3 finish. Should you require any other finish please contact Decon to select from the wide range of optional surface treatments.

Architectural fittings are finished to provide a smooth transition from the bar to the fork connection, this aesthetic appearance is enhanced by the use of Lock Covers, which combine the function of a lock nut, and a blending thread cover.

The connection to the structure should be made by utilising a connection plate with the same thickness and edge distance as the Macalloy spade shown in the tensile structure catalogue. All connections should be made using standard grade 50 material or stainless equivalent.

If connecting stainless steel to carbon steel, measures should be taken to prevent bimetallic corrosion. Isolation bushes and washers are available from Decon. The Macalloy tension structure design data book shows detailed edge distance and hole diameter.
