The Macalloy 650 stainless bar can be used as an alternative to end threaded stainless re-bar. The thread form complies with a Type 2 deformation in accordance to BS4449 and BS6744. The bar can be supplied as end threaded only as opposed to fully threaded. Download our brochures below for more information. Alternatively you can contact us; the details can be found at the bottom of this page.

Macalloy S650 is a high strength stainless steel threaded bar system available in 304 and 316 grade Stainless steel.

Stainless Re-barGrade 304 Stainless Steel is normally used in less corrosive environments and is adequate for most applications. Grade 316 has added Molybdenum enabling it to be used in more highly corrosive environments, for example, where this material may come into contact with seawater.

The system has a guaranteed yield stress of 650 N/mm². The thread is a cold rolled thread, similar to the standard Macalloy Pre-stressing bar. Standard lengths are 6m. Full strength couplers are available for longer lengths. The fully threaded bar has advantages over end threaded systems in that it can be cut to the precise length on site.

The Macalloy 650 Stainless is available from stock in diameters 16mm to 24mm. Other sizes up to 50mm diameter are available by special order. Also available within the Macalloy 650 Stainless range are dished plates washers, pattress plates, lantern spacers, and hemispherical load nuts.

Macalloy can provide technical and on site support. See separate pages for more information.
