Maintenance of Aluminium

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.

Aluminium sheets

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.

Aluminium Finishing Options – Organic Powder Coating

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.

Stair nosings – Regulations to consider for architects and specifiers

According to building regulations stairs, ladders and ramps have to be designed, constructed and installed in a way that is safe for people moving between different levels in or about the building. Gooding Aluminium therefore takes a deeper look at regulations to help ensure specifiers are compliant when installing aluminium stair nosings.

Stair nosings Size

According to Building Regulations (K&M), BS8300 and BS9266, the recommended dimension of a stair nosing should measure between 50-65mm and the riser 30-55mm. This ensures there is a large enough ‘band’ on the nose of the step.

Colour

Building Regs (K&M), BS8300 and BS9266 explain that the colour of the Stair Nosing is required to differ from that of the floor covering.

Every colour has a Light Reflectance Value (LRV) of between 0 (Black) and 100 (White). The documents indicate that there should be at least 30 points difference between the Stair Nosing LRV and that of the floor covering, e.g. If the floor covering has a LRV of 50, then the Stair Nosing should have a LRV of between 0-20 or 80-100. This helps create the ‘ladder effect’.

Slip resistance

The tread material used in a Stair Nosing is important for the safety and performance of a stairway. There are two recommended tests that can be carried out to determine the slip resistance of a flooring material.

The pendulum test (PTV) and a surface micro roughness measurement (Rz). Either of these can be used to give an indication of the slip resistance of a material, although the Pendulum method is limited in so far as it cannot be used to test material on site.

Coverage of the tread material

Looking at the guidance provided for the coverage of the tread material on the top surface of the Stair Nosing, it explains that the tread is the surface of the Stair Nosing which receives ascending or descending footfall. The IP 15/06 states that the Stair Nosing tread material should extend to the front edge to the point at which it meets the vertical face in order to minimise the risk of a slip in descent.

A guide to specifying bespoke aluminium

Gooding AluminiumAluminium 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.

Global construction market to grow by 85 per cent to $15.5 trillion by 2030

The global construction market is expected to grow by 85 per cent to $15.5 trillion worldwide by 2030, new research shows, with China, US and India leading the way and accounting for 57 per cent of all global growth.

construction

According to the latest study from industry analysts Global Construction Perspectives and Oxford Economics predicts that growth in the sector will outpace that of global GDP by over one percentage point at 3.9 per cent per year to 2030.

However he added that new types of construction in healthcare, education and social infrastructure, will help drive growth in the longer term.

“Meanwhile, we’re due to see a surge in construction rates in India as it overtakes Japan to become world’s third largest construction market by 2021,” Robinson added.

“Although globally we see construction growing more rapidly than the overall economy, with developed markets forecast to rebound from their depressed levels, many will not be back to their previous peak levels even by 2030,” Mike Betts at Global Construction Perspectives said.

A potential rate hike in the US, expected as early as December, could also mean a risk for construction growth in key emerging markets – Brazil, Russia, Turkey and India – the study warned, with some of these countries potentially halving growth.
