Alustep® W is a sandwich panel made of an aluminium honeycomb core and fibreglass skins impregnated with epoxy resin. Designed for use with very light-coloured marble, it features a uniform, bright white surface, allowing application without altering the stone’s natural hue. The composite structure provides good mechanical performance and high water resistance, making it suitable for wet cutting processes, where avoiding substrate absorption or delamination is essential. Alustep® W is a reliable technical solution for lightweight marble cladding, offering low weight, dimensional stability, and aesthetic compatibility with pale stone surfaces.
