The numbers in the title denote the yield strength of the Stainless Bars. Tension Rods are available in mill finish carbon steel, hot-dip galvanized, and stainless steel. The Macalloy tension bar system gained CE approval, long before it became mandatory practice for structural steel work throughout the EU.

It works by gripping the tension bar on 4600 side of the turnbuckle and pulling the bars together into tension and so loosening the turnbuckle.

Macalloy tension bars are available in a range of finishes including carbon, galvanized and the stainless steel range known as S and S The Macalloy S has been developed using high strength stainless steel to deliver optimum levels of strength, ductility and appearance. This gives rise to the use of smaller diameter bars for a given metric thread, resulting in material cost saving. Macalloy tension bars are the core component of the Macalloy tension structures range. Tension rods and cables systems are excellent for supporting tension loads, but not compression loads.

Download our brochures below for more information. MACALLOY Tension Rods are available in thread diameters ranging from 10mm to mm, and are available as unfinished carbon steel normally for later painting4600 dip galvanized, or stainless steel.


Macalloy are able to supply bar and cable systems to suit various applications from Airports to Stadiums to name but a few. For more details of yield loads, levels of adjustment and component dimensions please download the Macalloy tension structures brochure.


Originally developed for prestressed concrete structures the system is also used for a variety of other structural applications. Cable Systems are available in stainless steel.

Macalloy can provide support for installation and stressing of all our products. The Cross-Coupler allows simple diagonal bracing by permitting rods to intersect in the same plane.

Alternatively you can contact us; the details can be found at the bottom of this page.

They are available in stainless steel cable diameters from 4mm to 26mm, and in three different strand configurations to suit a range of engineering requirements. Bars are available with outer thread diameters from 10mm to mm.

The turnbuckle can then be tightened with a strap, chain or stilson wrench. Bars are available in lengths up to 12 metres with longer lengths achievable by connecting bars with couplers or turnbuckles. The Disc Connection provides an attractive architectural feature for the central connection of multiple tension rods used in cross bracing. A range of crossover and connection solutions are available, particularly applicable for bracing and cross bracing applications.

The Turnbuckle with Fin Plate allows long macally rods to be supported against sag by using additional vertical bracing. They are used for a wide range of architectural and structural applications. The thread is rolled, rather than cut.

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 range is also complimented by a full selection of rod coupling systems, center anchor discs, and compression rods.


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. Nearing completion and scheduled to open in earlyTizi Ouzou Stadium in Algeria.

Macalloy has supplied M85 Carbon Tie Rods in grade to help support the new stadiums roof. Contact Macalloy for further information. Special bar sizes and special solutions are available to suit specific requirements. Macalloy is continuously introducing new products to meet the various demands of the civil and architectural markets.

Compression Rods accommodate the structural situations where compression loads need to be supported.

Turnbuckles are a simple method to allow rod lengths to be extended while providing additional length adjustment. Macalloy Carbon Bars are a manufactured carbon steel. Site services support includes equipment hire, training of site personnel to install and tension bars and on site installation. The Post Tensioning System is available in carbon steel and stainless steel. Macalloy has considerable experience of using stainless steel in a chlorine environment and can offer advice upon specific grades for such applications.

Pre-tension jacking systems are also available. The tension bar system, which may globally be referred to as tie rods, tie bars or tension rods, provide adjustment of the total length.
