Planning your aluminium installation – A Handy Checklist

Aluminium installation must be planned carefully to minimise risk of damage during the fixing process.  Contractors should be instructed to carry out spot checks on sheet products covered with protective film before working or fixing commences, to ensure surface finish suitability.

Follow the brief checklist below for a hassle-free installation:

  • The lightweight advantage of aluminium (34% that of steel) over other architectural materials, makes for ease of handling and fixing with a minimum number of operatives. When handling individual sheets or panels, care should be taken not to damage exposed edges or corners. Thin materials are particularly vulnerable.
  • Aluminium items have a best and reverse face. Inspect closely and ensure the best face is fixed / positioned on the most visible side.
  • Material flanges which are oversize must not be forced or hammered into position. Components requiring a reduction in size should ideally be returned to the factory for re-processing.
  • Site work such as drilling and cutting, should be avoided if at all possible. If specified, items can be supplied as accurately pre-cut and pre-drilled components subject to agreed tolerances
  • When installing or working unprotected material surfaces, a low tack self adhesive tape or covering is to be applied to prevent surface marking.
  • When site drilling is unavoidable, standard twist drills are satisfactory for most operations. For deep holes, high speed drills or bits with a steeper point of angle should be used.
  • Positions for drill holes should not be marked out along visible faces with a scored line. A pencil, or felt tip pen with removable ink or similar is to be used, which can be subsequently wiped off with a soft cloth.
  • Cutting operations can be effected by semi high-speed and high-speed saws of between 150mm and 450mm diameter, with approximately 3 teeth per 25mm. Band saws and heavy duty woodworking machines are also suitable for light work. Blades used in hand saws should be of high speed type with fairly coarse teeth.
  • After cutting, it is important that any swarf or chippings are removed from the product surface with extreme care, to avoid the possibility of scratching. These should be removed ideally with an air line or alternatively by lightly brushing away. Burrs can be removed by the use of long angle files with 14 to 20 single cut teeth per 25mm, for most fine work.
  • Remove any grease, dirt deposits, finger marks, etc, from the material surface with non abrasive cleaning agents and materials, in accordance with the GA maintenance data sheet.

Perforated Aluminium Sheet: Useful Things to Know

It was none other than Ludwig Mies van der Rohe, the creator of the Barcelona Pavillion, (which is often described as one of the most beautiful 20th century buildings), who coined the phrase ‘less is more’. Van der Rohe could have been talking about perforated aluminium sheet!

What other material simultaneously provides so many design opportunities to combine its inherent strength to weight ratio and corrosion resistant qualities with a widely appreciated aesthetic appeal? By virtue of these outstanding attributes, perforated aluminium sheet is often incorporated into many architectural components as the primary element. These products would include balustrade panels, bar/counter fascias, ceiling panels, column casings, radiator/vent covers, wall cladding and so on.

It is often desirable to custom make perforated aluminium panels rather than fabricate from stock size sheets. This way the specifier retains much greater design flexibility by being able to incorporate plain borders and other unpunched areas, as well as, cut outs for lighting, vent ducts, etc. With the majority of round hole patterns being arranged on a 60 degree triangular pitch the plain borders are normally lost once pre-punched sheets are cut to size. Unless covered with a safety edge or hidden by some other component the resulting raw edge is a health and safety no no.

A guide to specifying bespoke aluminium

Aluminium is a highly versatile, lightweight and strong material and can be worked using a variety of metalworking techniques.

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.
