Product description

Extreme durability, low panel thickness and easy mounting make fibreStair the ideal product for stair renovations and intelligent solutions for steps.

Angled step elements

The fibreStair angled step consist of a pre-fabricated glassfibre element which is mounted on concrete stairs for aesthetic reasons and as modern and attractive stair cladding. Step tread and riser are one element, the tread/riser ratio can be chosen freely.

Block and wedge-shaped steps

fibreC block or wedge-shaped steps can be mounted to steel constructions.
They are stackable and can be armoured for cantilever staircases. Block steps are available in the colours silvergrey and anthracite.

Product family


fibreC is a high-strength, thin, flexible and mouldable material and can be used for flat, curved and all kinds of special shapes.
Owing to the unparalleled mouldability of glassfibreConcrete panels, its unrivalled slenderness and the entire production system as such, fibreC can be used for the most extraordinary applications.
The formation of closed corners and curves in one continuous piece and with uniform robustness opens up new perspectives for wall construction and interior design.
Formed parts and 2D elements are custom-made to achieve flowing transitions from interior to exterior surfaces and a smoothcovering for edges.
