Aluminium Interlocking Flat Decking System

Power Plastics’ bespoke aluminium flat decking system has been developed to offer a flexible, high quality and environmentally friendly odour control option.

The system consists of interlocking aluminium profiles, 205mm in width and up to a length of 10000mm, laid directionally to form an effective odour control cover. The decking boards are installed to be fully removable, with minimal labour requirements.

The decking system comes with full CE Certification to Execution Class 2.

Certification & Standards

The aluminium flat decking system will come with CE Certification and will conform with the following key standards:

  • EN1991 – Eurocode 1 Actions on Structures
  • EN1991 – Eurocode 9 Design of Aluminium Structures
  • EN1090 – CE Marking Structural Steel & Aluminium (Execution Class 2)

The harmonised standard EN1090 covers the adherence to 119 different European & ISO Standards, including the following key standards relating to this product:

Corrosion Resistance

The aluminium extrusion is extruded from a 6000 series alloy and has been used on a wide variety of odour control systems by Power Plastics. The decking will be provided with comprehensive material data sheets as part of the O&M Manual.

Aluminium is a passive metal, with the aluminium oxide layer produced on the surface during the early stages of corrosion preventing further corrosion from occurring.

Power Plastics have successfully used the aluminium decking system in highly corrosive atmospheres for major UK contractors such as Galliford Try, Laing O’Rourke and AMK Joint Venture. A 30 year life span can be offered on a contract by contract basis.

A4 Grade Stainless Steel fixings are utilised in the system. Any stainless steel materials will be A4/316 grade, with material certificates available as part of the O&M Manual.

Environmental & Asset Value

The aluminium decking system is 100% recyclable, with as much as 20% of the cost of the product recoverable at the end of the life cycle, turning the product into a physical asset for the end client.

The product also helps to significantly reduce the carbon footprint of the project.

Removal & Handleability

If the covers need to be retrospectively removed, the aluminium flat decking system is simple to remove and reinstall.

The system can be removed board by board, exposing as much of the underlying void as required.

The decking boards simply slide back together when reinstalling, with the concrete anchor reinstated to fix in place.

Due to the performance of the decking boards at spans of 2.5m-3.0m, costly and time consuming support structures can be avoided. The strength is in the extrusion.

Flexibility

The aluminium decking boards can be machined, cut and tapped as well as knitted together using bolt slots on the bottom face. This allows for the accommodation of protruding plant and pipes as well as shaping to follow wall lines. Strengthening angles can be attached to the bottom face to maintain the strength of the boards where there are penetrations of the system.
