GRADAS facing panels manufacturing most often involves the use of sheets from 5005 (EN573-3) aluminum alloy. This alloy in marked by perfect corrosion resistance, strain aging resistance and is easily processed.

Other alloys not affecting the product’s properties may be used for facing panels manufacturing. Technical inquiry and service requirements for building façade determine metal thickness and size of sheets. Maximal size of aluminum sheet processed equals to 4x2000x4000 mm.
