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. 24 pages
In order to be able to visually identify EN74 certified couplers, this guidance document identifies the specification and minimum markings to be found on all EN74-1:2005 and EN74-1:2022 scaffold couplers, together with brief details regarding the differences between the two standards. This product is available in PDF format only.

In an ideal world all working platforms should contain no gaps or holes. This updated guidance is a simplification of the previous 2003 issue regarding working platforms, which have additional requirements over those that are normally provided on an access scaffold. Quality and the thickness of ply used are integral. 4 pages
This guidance gives details of various methods available for satisfactorily securing scaffold boards to prevent movement. Users should satisfy themselves when/which boards require tying down and that any proprietary equipment or fixing method selected meets their requirements.

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
Many free-standing scaffolding structures, such as access towers, major signboards, fences and enclosures, need to be anchored to the ground, primarily to resist wind forces. Whilst all structures requiring restraint via anchoring to the ground should be subject to a bespoke design produced by a competent engineer, the guidance considers different types of anchors available and typical indicative holding capacities, the possibility of disturbing underground services, the use of guys and scaffold tube restraint. 6 pages
The effects of heat on scaffolding equipment can have a significant and permanent effect on its strength and performance. This guidance explains the potential issues and the action to be taken if equipment has been subjected to a fire or similar conditions. This guidance is available for pdf download only.
Scaffold tube storage racks are a common feature of every scaffolding contractor’s yard and many long-term live sites. Whilst tube racks are usually constructed as basic birdcage-like structures, they generally support many tonnes of equipment, so their design needs special consideration. This guidance note considers the design, use and maintenance of scaffold tube storage racks. 6 pages
This guide is intended to aid those who commission scaffold designs by summarising the responsibilities of each party involved at each stage of the process. It also details the requirements for preparing a design brief with information required by the Designer to enable a suitable and sufficient design to be produced, as well as outlining the design process, checking requirements and expected output information. This document is complimented by CG6: Scaffold Design. 6 pages.
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. 6 pages
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.
