 Origin
and Functions
Aluminium Composite Panels are a stable and flexible material for
wall cladding, combining the beneficial properties of aluminium
and plastic to provide an economical and yet elegant alternative
for modern architecture. Versatile and light in weight, as well
as weather and temperature resistant, aluminium composite panels
are easy to install. These benefits have led to its wide application
in construction.
Economical
Being light in weight, thus reducing load on the building, means
a low cost for supporting structures and fixing accessories. The
added advantage of this feature is that it makes construction and
installation easier and more convenient, thus directly speeding
up the construction process.
By using colour coating of the highest quality, aluminium composite
panels can save costs on long-term repair and maintenance.
 Flexibility
Aluminium composite panels can be easily cut, folded and shaped
on site using conventional tools and machines. Apart from being
adaptable, this leads to ease in installation.
Durability
Our PVDF coating is UV protective, resistant against high temperature,
weather, corrosion and abrasion.
Design
AL-PE composite panels are elegantly suited to modern architecture.
Apart from the readily available colours we provide, we can also
produce panels to our client's request.
