Steel & flat-steel stairs

Carried by steel.

In these stairs a steel structure carries the wooden treads – as a strong steel stair or as a slim flat-steel stair with a folded steel stringer. Clear, modern and very strong.

What makes it special

Why a steel stair?

01

Very strong

The steel structure handles long spans and heavily used stairs.

02

Slim line

Flat steel follows the treads as a fine, folded outline – light and graphic.

03

Any colour

Powder-coated in black, anthracite, white or a colour of your choice.

Frequently asked questions

Good to know

What is the difference between a steel stair and a flat-steel stair?

In a flat-steel stair a narrow steel stringer, folded to follow the treads, carries the load; in a steel stair it is a heavier steel structure. We advise you on what suits your room.
