Gratings and grating solutions are common in the process, paper and construction industries, among others. The gratings can be walkable treatment bridges or drive bridges for vehicles. The gratings are utilized in various ramp and tread solutions as well as spiral staircases. Emergency exit stairs, which are mandatory in all buildings, are usually made of gratings.


High quality approved gratings

Our products are high quality and durable. Quality control has been taken care of – the gratings are CE approved. Our Dutch-German factory has 30 years of experience in the field and the gratings are manufactured in Europe.


Stair treads

Metal treads for outdoor and indoor use. The treads are made of pressed or welded grating. At the front edge of the tread there is a sliding safety strip, which improves the grip and safety of the treads. There is a choice of materials for the treads, the treads are available in galvanized, carbon steel and stainless steel. Our selection includes a wide range of different tread solutions – in addition to stock products, we also manufacture tread solutions according to dimensions.

Staircases are used both outdoors and indoors. We supply treads to various operators in the industry, including the construction, process and paper industries, as well as power plants. The materials of the treads are selected according to the application and purpose. Galvanized and stainless steel are also ideal for outdoor applications.

Straight stairs and Spiral stairs

We supply both straight stairs and spiral staircases. A spiral staircase is a quick and cost-effective option when the space of the staircase is limited. The spiral staircase fits into even a small space and is an excellent solution for a safe emergency exit. Our range of spiral staircases includes stairs for both indoor and outdoor use.

Safety and non-slip treads

Instead of a normal press-welded grating, the treads can also be made of a safety or anti-slip safety grating. These treads improve occupational safety and prevent accidents at work.

The safety grating has a denser mesh size than a normal press-welded grating. The denser spacing of the treads prevents, among other things, tools from falling and accidents caused by them. The surface of the anti-slip grating, on the other hand, is cerrated, so it is more durable than other gratings. The anti-slip grating is utilized in slippery conditions and in places where the treads may be exposed to oil, soap or ice, among other things.

Handrail solutions

We offer a complete staircase solution: in addition to steps and stairs, we also supply railings and all the necessary fasteners and accessories. In railing solutions, for example, perforated sheets can be utilized. Perforated sheets are durable and impressive railing and protection solutions – railings complete the staircase and affect the safety of the staircase.
