CONSTRUCTION FIXINGS Leading the way
Andrews Fasteners Ltd continues to be one of the leading fastener suppliers in the UK. Having led the way with the introduction of colour coded bags (according to diameter), sizes stamped on the bolt head, colour coded labels (to indicate the finish on fasteners) and by supplying assembled products, Andrews has made products easily identifiable on sites.
assessed by Lloyd’s Register Quality Assurance UK (LRQA) and the company now holds CE approval for Preload (BS EN 14399) and Non – Preload (BS EN 15048) fasteners, and is also approved to the National Highways Sector Scheme 3. Assembled stocks of CE approved and non-CE fasteners are
A
available in self colour, galvanised, bright zinc plated (CR3) and sherardised finishes. Square square holding down bolts, washer plates and a vast range of blanks are also ex stock items. Andrews is an accredited stockist for Lindapter, Rawlplug,
fischer Fixings, TurnaSure DTIs and many other products. Andrews also has the capability to manufacture items to special requirements such as, shoulder bolts, tie bars and longer length bolts or setscrews. With the company’s own in-house testing facilities both in Leeds and Malaysia, Andrews’ customers can be assured of
ndrews’ innovations are now standard practice in the UK and have been adopted by the British Constructional Steelwork Association (BCSA). More recently, Andrews’ Quality Management System has successfully been
receiving quality products, which can be supplied with test certificates (2.2/3.1/3.2). In recent months Andrews’ solely owned factory in Malaysia
has begun production. Andfast Malaysia will enable Andrews to manufacture and stock a large range of assembled fasteners (from M6 to M64) for global supply. For more information customers can access the Andrews

Lindapter’s design specified at Gatwick Airport
Steelwork fixing specialist Lindapter has designed a unique high capacity support assembly to secure a new baggage system to existing steel beams as part of the £31 million Gatwick North Terminal baggage upgrade.
T 66
he brief required a method of connecting vertical SHS hollow sections with stiffened end plates to various types of structural sections including castellated beams, whilst delivering a safe working load capacity of 250kN per connection. Lindapter’s technical support engineers proposed the use of Type AF24 clamps with grade 10.9 bolts
in a bespoke hanger assembly. The design fulfilled the significant load requirements and vibration considerations, and also removed the need to drill or modify existing steel beams thereby allowing a faster installation. Lindapter’s drawings and calculations were presented to the consulting civil and structural engineers
who approved and specified the Lindapter connection for use at the UK’s second largest airport. During installation, the ease of adjusting the Lindapter fixings simplified the precise
alignment of the baggage system, despite being suspended from various sized beams throughout the span of the upgrade. A further advantage at the construction phase was that a hot working permit was not needed, removing any associated and potentially costly construction delays. Gatwick along with Doha and Dublin T2 are the latest in a number of airport projects to utilise
Lindapter components and assemblies, with typical applications including securing structural steel, aluminium curtain walling and suspending building services. Lindapter’s high strength Type AF fixings are approved by TÜV Nord, verifying the tensile performance
of a 4 bolt girder clamp configuration of up to 250kN and 70kN in friction. An international distribution network provides worldwide availability of sizes M12 - M24, supplied hot dip galvanised as standard for extra corrosion protection.
