Being both lightweight and ductile, aluminium readily lends itself to fabrication.
However the un-initiated should tread carefully as there is no substitute for experience in specifying fabricated aluminium. It might, therefore, prove helpful if I share some key pointers with you, and these are;
ProductionTolerances: How long is a piece of string? There is no such thing in aluminium fabrication as an exact dimension. Every measurement is subject to a production tolerance. If sizing is critical, make sure you agree specifics with us before fabrication commences. If requested and to ensure a satisfactory ‘fit’, we can normally provide measurements that are ‘no greater than’ or ‘no less than’.
Aesthetics: To quote from Shakespeare ‘Beauty is bought by judgement of the eye’. Workshop processes will literally leave their mark on all metal surfaces. If aesthetics are important, and they often are, consider the intended location of the fabricated items. Lighting conditions, viewing distance and angle, etc., are among the elements that need to be taken into account.
Working from the premise that ‘prevention is better than cure’, sheet materials can be covered with a peelable protective film prior to production. This best practice precaution certainly assists in reducing, but not necessarily completely eliminating, surface marking. Sheets are normally supplied with one good side (unless otherwise specified). It is also sometimes possible to ‘hide’ surfaces liable to workshop abrasions, as long as the visible faces are identified to us prior to fabrication.
The term quality has little significance when related simply to product.
‘Quality’ to Gooding Aluminium is about delivering a complete and satisfactory standard of service from the pre-specification stage through to job completion and product performance.
To ensure consistently high quality standards are maintained we seek continuous feedback from our specifier base, this flow of information helps us to adjust policy as and when necessary:

Even in polluted, industrial scenarios, aluminium is extremely resistant to weathering which is why it is broadly considered to be a low maintenance metal and a great choice for construction. When exposed to normal environments, aluminium only shows minor superficial deterioration over long periods of time.
Coloured effects and special finishes such as powder coatings and anodising can be applied to aluminium in order to enhance the durability of the product.
We supply a range of aluminium products and fixings to architects, specifiers and professionals within the built environment.
For many uses aluminium looks great in mill or anodised finish. There are occasions however when a colourful alternative may be required and that’s where GA’s ‘Spectra Bond’ powder coating (available in RAL colours) comes into its own.
The long-term performance characteristics of the environmentally friendly solvent free powder coating process, ensure wide usage for architectural projects. Often selected as the preferred option for fabricated items because the thickness of its coating often covers surface abrasions and processing marks. The thermally cured powder coating process provides a tough, easy to maintain and knock-resistant finish.
We are a national and international supplier of a wide range of high quality aluminium products including
An increasing number of architectural projects involve the specification of worked aluminium. To assist with this process and to ensure the product realisation meets your expectation we would like to share with you some important design considerations.
Bespoke working involves making items to specifier requirement on a one-off type basis. Job specific – quantities, sizes, shapes, radii, fixing details etc., are all incorporated into the finished item.
With each unique specification there is a first time for everything. It is always possible that unexpected developments can arise.
Practical consideration in terms of material performance and / or machine capabilities can therefore cause some variation to the originally specified requirements. Tolerances with specially made items are generally looser than those for manufactured parts.
Component size can have a critical bearing on overall job cost effectiveness. Closely compare preferred size requirements to standard stock configurations. Small dimensional adjustments are often possible and can achieve significant financial savings.
Corner radii on bent / formed items are determined by a combination of material thickness and alloy grade. A radius on the outside corner, of up to twice the metal thickness, is possible.
Countersunk holes cannot be provided on material thinner than 1.2mm.
Crazing of anodic coatings will occur due to mechanical influences such as forming or bending. Anodic crazing by cold deformations of all kinds can be avoided by ensuring that these precede the anodising process.
Dimensional tolerances apply to all bespoke products.
Grain structure on brushed surfaces is best designed to run vertically, this minimises dirt entrapment and eases cleaning. Mill and anodised surface finishes can clearly show the metal grain and it is therefore preferable to avoid adjacent component surfaces with conflicting grain direction.
Insulate at connections with other metals, for maximum durability.
