The Challenger Staircase is Zakuna’s bold expression of zig-zag staircase design, featuring two flat steel strings on either side that create a striking angular aesthetic.
The contemporary styling celebrates the geometry of the stepped pattern, making the staircase itself an architectural feature. Often called the ‘Zig-Zag Staircase’, the Challenger Staircase is popular with architects and designers working across both residential and commercial sectors, offering a versatile design that works equally well in luxury apartments, contemporary homes, commercial offices, and retail environments. The dual string configuration can incorporate curves, kites, and winders, providing surprising flexibility for complex spatial briefs. The strings can be double-skinned for enhanced visual impact with glass balustrades and concealed glass fixings. Available in any RAL colour, stainless steel, Corten steel, or galvanised steel, the Challenger Staircase offers extensive customisation. An optional integrated LED lighting system within the strings can add sophisticated ambience.
The Challenger Staircase proves that functional engineering can deliver visual drama. The dual flat steel strings create powerful angular lines from every viewing angle, whilst the zig-zag pattern is both architecturally striking and highly practical.
