Macalloy is continuously introducing new products to meet the various demands of the civil and architectural markets. Macalloy are able to supply bar and cable systems to suit various applications from Airports to Stadiums to name but a few. Download our brochures below for more information. Alternatively you can contact us; the details can be found at the bottom of this page.
Macalloy tension bars are the core component of the Macalloy tension structures range. Macalloy 460 Carbon Bars are a manufactured carbon steel. The thread is rolled, rather than cut. This gives rise to the use of smaller diameter bars for a given metric thread, resulting in material cost saving. Two standard strength systems are available within this range; the Macalloy 460 range with a yield strength of 460 N/mm2 and Macalloy 520 with a yield strength of 520 N/mm2.
Macalloy tension bars are available in a range of finishes including carbon, galvanized and the stainless steel range known as S460 and S520. The numbers in the title denote the yield strength of the Stainless Bars. The Macalloy S460 has been developed using high strength stainless steel to deliver optimum levels of strength, ductility and appearance. The Macalloy S460 yield strength is 460 N/mm2. Macalloy has considerable experience of using stainless steel in a chlorine environment and can offer advice upon specific grades for such applications. Contact Macalloy for further information.
Bars are available with outer thread diameters from 10mm to 100mm.
The tension bar system, which may globally be referred to as tie rods, tie bars or tension rods, 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 gained CE approval, long before it became mandatory practice for structural steel work throughout the EU.
For more details of yield loads, levels of adjustment and component dimensions please download the Macalloy tension structures brochure.
