Compression Struts
Macalloy offers two types of compressions struts:
Macalloy Architectural Compression Strut
The Macalloy Architectural Compression Strut provides an aesthetically pleasing long taper to each end of the compression strut.
The system uses the same fork end system as the Macalloy tension bar and cable systems, allowing for a successful combination of all three systems.
Available in either carbon, galvanised or stainless-steel finish, the Architectural Compression Strut comes complete with an adjustable locking collar that provides a seamless link (hiding the thread used to connect the fork) between the fork end and the strut.
Available in all major CHS (Circular Hollow Section) diameters from 33.7mm to 323.9mm. Custom dimensions are available on request.
Macalloy Fixed Compression Strut
The Macalloy Fixed Compression Strut provides a cost-effective, architectural alternative to the standard finish applied to standard hollow tube sections.
The fork is designed with the same critical dimensions as the standard Macalloy fork end, which means it can be used in conjunction with other Macalloy systems.
The Macalloy Fixed Compression Strut is available in carbon steel as standard. A galvanised option is also available.
Standard sizes are available for CHS diameters 33.7mm to 323.9mm.
Larger sizes and stainless steel are available as special orders.

Macalloy & Tekla Software
Macalloy has been working closely with Trimble, an industrial Technology company, to develop BIM models for our tension rod and compression strut range for use with Tekla software.
With the increasing prevalence of Building Information Models (BIM) being used in the building process, Macalloy has developed its architectural tension rods and compression struts into BIM objects.
Macalloy BIM objects are designed specifically for use with Tekla Structures, these native objects offer the designer easy snap-to points and the latest functionality.
Available for download on the Macalloy website and Tekla warehouse.

Hollow Bar System
CMP hollow bar system is a fully threaded hollow core bar that is initially a server as a drill rod with a lost bit, and later, once grouted in, it becomes an anchor tendon that can be stressed and locked off with a nut. CMP hollow bar system provides the optimal solutions for nailing, bolting, micro piling and as ground anchors in difficult ground and rock conditions. It has many advantages including :
• Drilling, anchors installation and grouting are in one single operation, it is easy and fast to install.
• An economic alternative to anchors installed with cased drilling.
• Simple systems, low requirements on personnel
• No separate anchor installation or removal of casing and drill rods, increase productivity.
• Easy stressing operation.
• Flexible in length by using couplers.
• Choice of drill bit for different ground conditions.
• Enhanced corrosion protection’s available upon request.

Connection Discs
Cross braising connection solutions -Plus photo of disc
Macalloy has a range of Cross Bracing connections solutions, including ;
Cross -Couplers , Turnbuckles and Connection Discs
Cross- Couplers are used for bracing structures and range from M10-M120 with standard intersecting angles of 40 degrees and bespoke solutions up to 20 degrees. They provide a more elegant option to a connection disc when used in certain applications.
Turnbuckles, are also known as tensioners and are primarily used to adjust the length of the tension rods . They are used in applications where there is more than one bar to a tendon.
Connection Discs are available in sizes M10 − M76 but bespoke sizes are available on request.
A connection disc allows tension rods to lie in the same plane whilst forming a cross bracing. This negates the need to offset the tension rods.
Our website has a FAQ section on all these products, please follow the link below:
