BS2482:2009 defines both visual and machine strength grading standards for 38mm x 225mm boards supported at 1.2m spans and 63mm x 225mm boards supported at 2.5m spans; and machine strength grading standards only for 38mm x 225mm boards supported at 1.5m spans. This guidance is reviewed on the basis of removing A grade boards that should not exist. A visually graded board is still a BS2482 product and should be marked as such on the end band.

Traditionally, flame retardant timber decking has long been a fundamental requirement for scaffolding in various sectors of the industry. However, in the light of the ‘Grenfell’ disaster, there has been a substantial increase in the number of contracts which specify the need for flame retardant scaffold boards. This document gives details of various fire retardant treatments available, the recommended specification and guidance for care and storage. This guidance is available for pdf download only. 2 pages.
When in use, scaffold boards are often subjected to harsh conditions and mistreatment and may deteriorate to such an extent that they become unsafe. To ensure that they remain in a safe and serviceable condition, they should be subjected to regular inspections/checks and where necessary repaired/refurbished to ensure that they remain fit for purpose. This document provides guidance on the inspection, care and maintenance of scaffold boards to maximise their operational service life. This guidance is available for pdf download only.
Scaffold board nailplates are specially stamped toothed strips of galvanised steel that can be applied to new or used boards to prevent or to repair existing end splits. Experience gained over many years by the scaffold industry indicates that the service life of a board can be substantially extended if nailplates are fitted. This revised and updated version contains additional information and guidance on the specification and fitting of nailplates.

This document provides best practice for the use and application of steel and aluminium prefabricated beams. Included is information regarding beam types, uses, joints, handling, transportation and storage. Due to the wide variation of beams available on the market, it has not been possible to include individual load capacities, but information regarding tension and compression chords, correct methods of lacing, bracing and connections to standards and puncheons provides vital information to ensure that beams are correctly installed to support their maximum safe working loads. This guidance is available for pdf download only.
This guidance explains the differences between ‘supplementary’ and ‘check’ couplers and gives typical design applications where high coupler forces could be expected and where additional loadbearing capacity to connections may be required. It also contains guidance on coupler configurations and expected safe working loads (SWLs) where supplementary couplers are used. To ensure that SWL values are as accurate as possible, data provided within this document is based on practical testing rather than calculation. 2 pages
Aluminium tubes, prefabricated beams and other components are widely used throughout the scaffolding industry. Whilst aluminium is not as stiff as steel and will deflect more when subjected to equivalent loads, it is much lighter and provides great advantages with regard to manual handling or the reduction weight. As aluminium couplers are not readily available, aluminium tube and beams are invariably connected with steel couplers and joint pins. Unfortunately, when two dissimilar metals such as aluminium and steel are in contact, a phenomenon known as ‘galvanic corrosion’ can occur where the corrosion of one of the metals, in this case aluminium, can be greatly accelerated. In severe cases this could seriously affect the integrity of the scaffold structure.
