What makes it special

Why a stringer stair?

01

Extremely strong

The stringers carry every tread from both sides – even with long spans and heavily used stairs.

02

Steel or wood

Steel stringers powder-coated in black, anthracite or a colour of your choice – or stringers of solid wood.

03

Full of character

A clear design statement for lofts, new builds and modern houses.
