Stair treads – standard design or customised version

HighSolid stair treads for resilient steel stairs

The essential components of stair treads are the safety edge, the side plates as well as the tread made from grating. The safety edge is perforated and acts as an additional anti-slip mechanism when stepping onto the stair.

With the help of the side plates on the steps these can be easily screwed onto an existing structure. Application areas of the stair treads can be either inside or outside of buildings. Be aware of slipping hazards caused by weather conditions or slippery substances appearing on the anti-slip tread.

Each stair tread and step has a perforated anti-slip safety edge. All side plates have a drilled hole and a slotted hole to facilitate the alignment of the outside edges during assembly. The stair treads for the various indoor and outdoor steel stairs are manufactured with the same bearing and cross bar dimensions as the gratings.

Naturally you can also order custom-made stair treads.
In principle, all stair tread variations are possible in Neuhaus HighSolid quality. The availability of trapezoidal treads alone creates many possibilities.

Construction directives for steel stairs according to DIN 24 530

The increase ratio s of the stairs is a: 1.73 to 1: 1.0 corresponding to a slope a = degree is 30 ° to 45 °. Appearance and slope are in a certain relation to the pace of the people. For a good accessibility of the stairs: 
2s + a = 590 - 630. 2s + a = 590 - 630

Staircases with more than 4 steps must have a handrail. After max. 18 steps a landing must be provided.

Our consulting offer also applies to the implementation options for custom orders: We will do everything we can to meet your architectural and construction needs.
