Round bending handrails ø42 mm in Bendywood® oak
directly mounted on steel stair stringer

Customized lengths

Outer handrail:

The 5,5 m long handrail was provided with a 6x22 mm groove, delivered pre-bent on a flat mould with radius 100 cm and mounted directly onto the 5 mm thick steel stair stringer.

The handrail was screwed laterally to the stringer at a distance of approx. 50 cm using fully threaded Spax screws with a small head 3,5x30 mm in order to prevent further longitudinal shrinkage of the handrail in the long term. The drill holes were puttied.

Inner handrail:

The 4 m long handrail was pre-bent on site on an ascending mould, similar to the following example: Mould for bending handrail with U-curve
Because of the strong torsion of such a steep handrail, the groove can only be marked at the bottom of the handrail after the pre-bending and then milled with the router. After that, the final fixing is carried out in the same way as for the outer handrail.

On the landing, such a handrail is not jointed by means of a mitre joint, in order to avoid an opening up of this type of joint later on. The used solution is aesthetic and allows the handrail to further shrink in length.
