There are many different manufacturing and prefabrication processes involved in the creation of a SureClad® ceramic granite ventilated façade panel.
Pure raw materials are sourced from across the world - clays, fieldspars, minerals, pegamites and metal oxides. No resins, cements or other binders are used.
These powders, rocks and minerals are amalgamated, wet ground to a fine powder, refined to remove impurities and turned into a perfectly homogenised slurry.
The slurry is injected at high pressure and nebulised inside a spray dryer. The contact with very hot air causes instant and even drying.
Using a unique patented method, the dried materials are mixed and are then subjected to intense hydraulic pressure - typically over 12,000 tonnes.
The pressed slabs are fired at 1260°C until fully vitrified: impervious to water, dust or chemical attack. During the firing process the constituent parts become irreversibly fused without any need for bonding agents.
At this stage the ceramic granite slabs can be left with a natural unpolished finish or can be given a semi-lustre or high sheen, diamond polished surface. No chemicals are involved in the polishing process.
Every ceramic granite slab is checked electronically and by highly trained technicians for uniformity of colour, structural integrity and critical sizing.
