EXPERIENCE INNOVATION QUALITY

Since the 1940’s Macalloy has been leading the way in the design, manufacture and supply of threaded bar systems, consistently serving its various markets with experience, innovation and quality.

Macalloy’s compression strut range builds on the tension structure products range and provides an adaptable, architectural solution across all budget and design parameters. The compression strut product range incorporates two

adjustable and one fixed solution, all of which are designed to be used in conjunction with the Macalloy tension structure range of tension bars, stainless cables and connection solutions.

Macalloy Architectural Compression Strut

The Macalloy Architectural Compression Strut provides an aesthically pleasing long taper end to each end of the compression strut. The Architectural system uses the same fork end system as the Macalloy tension bar and cable

systems allowing for combinations of all 3 systems. The Architectural Compression Strut comes complete with an adjustable lock collar that provides a seamless link between the fork end and strut. Available in both stainless and carbon steel.

AdvantagesPleasing architectural designAdjustment of the total length is permittedLock collar provides a seamless finishCompatible with Macalloy tension bar and cable systems

Macalloy Standard Compression Strut

The Macalloy Standard Compression Strut has a shorter taper end than the Architectural strut and does not use the locking collar. This provides a more cost effective solution. The Standard Strut still uses the same fork end system as Macalloy tension bars

and cables allowing for combinations of all 3 systems. The total length is adjustable. Available in carbon steel.

AdvantagesCost effective solution with fork end system.Adjustment of the total length is permittedCompatible with Macalloy tension bar and cable systems

Macalloy Fixed End Compression Strut

The Macalloy Fixed End Compression Strut provides an aesthetic, cost effective alternative to the industry standard steel T section welded to the end of a CHS. The fork end maintains the same critical dimensions as the Macalloy tension structures range enabling the use of single connection plates for multiple Macalloy systems. Macalloy will supply only the end forks from stock, which can then be

welded to a locally sourced CHS on, or near site. Available in carbon steel as standard.

AdvantagesCost effective solutionAesthetically pleasing design compared to standard CHS solutionsEasy to installAvailable from stock
