TG4:19 had amendments predominantly in relation to the orientation of ring bolts where current thinking is that settlement is probably greater than side wind loads so reduces potential shear loads on the bolt. Other minor changes were cosmetic. A recent update in April 2019 saw the removal of one reference only when the guidance was reissued as TG4:19.
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.
This document aims to give advice on 38x225 BS 2482:2009 1.5 m support span boards | 38x225 BS 2482:2009 1.2m support span boards | 63x225 BS 2482:2009 2.5m support span boards | 38x225 BS 2482:1981 1.5 m support span boards.
Updated 2015 version is a change of date only. Scaffold board nail plates are specially stamped toothed strips of galvanised steel that can be used to help prevent scaffold boards developing splits, or in repairing scaffold boards that have split. This guidance gives details on the manufacture and installation of Nail Plates.
This guidance on the use of scaffolding equipment that has been exposed to excessive heat, such as during a building fire and whether it can be safely re-used. Cost of fire damage evaluation does not warrant recovery of metal components.
A temporary roof or building is a sheeted structure designed to protect the area inside from the effects of weather, dust, etc. This guide is intended to give design and construction information to the suppliers and erectors of temporary roofs and buildings and intended for use by contractors during the building process.
This guidance gives details of the Fire Retardant treatments available for timber scaffold boards and battens.
This guidance gives details of the stress corrosion cracking (SCC) that can occur in certain materials when subjected to tensile stress and specific corrosive environments. Although rare in our industry, it can lead to unexpected sudden failure of certain metals. Whilst chemical environments and alloys are highly specific, this guidance explains the process by which SCC can occur and advises that specialist advice may be needed where SCC is possible or has occurred in the past.
