The system, which was developed for use on offshore oil and gas platforms, consists of engineered aluminium extrusions anodised to AA25 marine grade and fabricated brackets which are bolted together to create support frames.
An anodised Alphastrut channel and grade A4 stainless steel fastening were sent to an independent UKAS approved laboratory, which carried out corrosion tests in line with ASTM B117 and ISO 9227 standards.
Both components passed the 2,000-hour salt spray test, demonstrating that Alphastrut has comparable corrosion resistance to conventional stainless steel support frameworks.
Copies of the test reports are available on request.
The Alphastrut aluminium support system can be used for everything from load-bearing raised access floors to ceiling grids and bulkhead supports, and has been selected ahead of stainless steel frameworks for a range of offshore projects, including North Sea platforms for BP, Nexen and Det norske.
