• Transport

Alumiclad^® is the aluminium composite panel of choice for the twenty first century, an economical synthesis of aesthetics and function.

Rigid and Lightweight

Alumiclad is lightweight,flat and highly rigid due to the sandwich panel design, making it ideal for sign and display applications. Alumiclad 3mm panels are as strong as 2mm solid aluminium sheets and 10mm rigid foam PVC, but almost half the weight.

Compared to products of equal rigidity, Alumiclad is the lightest per m2

Weather Resistant

Alumiclad has a factory applied polyester lacquer, which is durable and allows it to perform for the long term in all types of climatic and environmental conditions.

Superior Finish

The smooth surface and excellent flatness provides an ideal surface for sign and display manufacturing. Alumiclad^® can be digitally and screen printed, have vinyl lettering applied and can also be spray painted.

Workability

Alumiclad is easy to cut, bend, groove and machine, making it extremely flexible and suitable to a variety of sign applications.

Recyclable

The aluminium cover sheets and core material that make up the Alumiclad panel are totally recyclable and environmentally friendly.

Fabrication Methods

	A major feature of Alumiclad is the possibility to form the panels into a myriad of shapes using a simple routing and folding method. It enables a fabricator to produce various shapes without the need for heavy equipment such as folding machines or brake presses. Hand routers and sheet milling machines can also be used. They are inexpensive and can be used either in the workshop or onsite. Refer below for specifics on achieving the best outcomes.
	Alumiclad PE or Alumiclad FS can be cut easily with circular saw, vertical saw or jig saw as used for metal or wood cutting. Carbide tipped blades for aluminium or plastic are recommended. Thickness of cutting teeth should be 2 – 4mm and tapered from outside in to prevent jamming. Shear cutting with a guillotine is also an efficient method for sizing a large quantity of panels. Please note that shearing will cause a slight deflection of the cut edge on the impact side and protection pads should be used to minimise any surface damage
	Routing or grooving the Alumiclad panel allows it to be folded easily. For processing large quantities of material a circular saw or panel saw with a groove cutter is recommended. A carbide tip should be used and we recommend 110o of grooving angle to achieve 90 o bends. It is important to leave 0.2-0.4mm of core material when U grooving (on the inside of the outer cover sheet).
	Alumiclad PE or Alumiclad FS can be punched using conventional sheet metal punching machines or manual punches. To achieve the cleanest edges use sharp dies and tools. Please note that punching will cause a slight deflection on the impact side of the cut edge. The panels can also be drilled with high-speed steel drills with centre point
	Alumiclad PE or Alumiclad FS can be bent easily using a folding table or brake press where the minimum required inside radius equates to ten times the panel thickness (r = 10 x t). To protect the surface during bending use padded strips. For larger radius a 3 roll bending machine should be used. It is best to groove and slit the curving edge before bending. Rollers should be polished and free of dents and other defects.

 

 

General Information

Screwing of Alumiclad panels can be done so with conventional wood, sheet metal or machine screws made of stainless steel or aluminium. It is important that an allowance is made for thermal expansion and possible building movement. If screws are used made of any other metal, a barrier such as plastic washer must be used, as the interaction of other metals with aluminium can lead to corrosion.

Bonding is possible with double sided VHB tape or adhesive sealants (dependant on type of application). The double sided VHB tape or adhesive sealants do not adhere to the panel core and thus must be applied to the aluminium cover sheet only.

Riveting is possible using solid or blind rivets made of stainless steel or aluminium applied with conventional riveting tools. It is important that an allowance is made for thermal expansion and possible building movement

Linear Expansion - Alumiclad is appropriate for uses in temperature ranges between –50C° and +80C°. Its linear expansion totals 0.024 mm/m/ C°, which amounts to 2.4mm/m during a temperature fluctuation between -20 C° and +80 C°.

Storage and Handling - It is important that Alumiclad panels are stored, handled and cleaned correctly. The panels should be stored flat and kept in a dry environment. Alumiclad has a plastic film protecting the surface of the panel during fabrication and installation. This should be removed as soon as possible after installation completion. Arrows are printed on the film to indicate the direction of coating.

Cleaning - The level of cleaning required is typically dependant on the environmental conditions of the installation (pollution, costal salt spray etc.) but in normal instance cleaning once a year is sufficient. The Alumiclad coating will not normally show an appreciable amount of dirt collection and rainfall will often be sufficient to keep the surface clean. Where additional cleaning is required, low water volume at moderate pressure, mild detergent and soft sponges or rags should be used. A non-visible area should be tested first. Do not use strong alkaline, acid or abrasive cleaners. Ideally cleaning should be done on the shaded side of a building at moderate temperature.

Colour Solutions

STANDARD COLOURS

 

Alumiclad is available in Alumiclad 10 or Alumiclad 15. Alumiclad 10 is a durable and weather resistant coating best suited for internal and low level façade applications not in proximity to the coastline. Alumiclad 15 is a PVDF coating, which is extremely resistant against weathering, UV rays and harmful pollutants and is recommended for exterior use and premium architectural applications. These coatings are applied to the aluminium coil prior to lamination into a composite panel, using a continuous coil coating and baking process, which is based on the latest technology. These consistent and quality coatings in a range of colours will aesthetically enhance any building as well as protect it from the elements. Colours not listed in this chart are available on request and subject to minimum order quantities. Colour reproduction in this chart is subject to printing limitations. For consistency of colour, batches should not be mixed. Please refer to additional technical advice for storage, installation and cleaning of panels.
