Porcelain and granite most certainly have their place in the building industry, with a variety of colours and finishes often providing great aesthetics. These materials are a good option for ground-level installations, such as patios. With a highly brittle nature, however, porcelain and granite are very susceptible to damage from misuse or accidents, which often leads to a condition of disrepair which can lead to further degradation once the surface is compromised, introducing safety concerns such as the potential for reduced slip resistance.
Galvanised steel is a strong and highly durable material and is often an excellent choice for high-traffic walkways, such as in commercial or industrial settings. It is susceptible to damage of the galvanised coating, which can allow the onset of corrosion and eventual breakdown. The aesthetic quality of steel grating is also undesirable to many people in a domestic setting due to its associations with industrial application. Safety issues can involve increased slip risks in wet conditions, particularly if the surfaces are not cleaned regularly.
Aluminium is a strong and durable material, able to withstand decades of use with minimal maintenance. A key property of aluminium is that it does not rust, even when exposed to wet environments over many years. Aluminium decking with a powder-coat finish provides a near-zero maintenance solution for use in balconies and terraces, with just simple cleaning required. Highly resistant to damage due to its inherent strength, the aesthetic properties, slip resistance and durability of powder-coated aluminium decking can be expected to last for decades.
