With a total height of just 23 mm, the Isostep substructure profile is the solution for flat superstructural parts. Thanks to its low height, the rail is perfectly suited for use on level surfaces such as concrete floors, paving, and tiles and can be used wherever a low structure is required due to the installation situation (e.g. balcony).
Isostep is a powder-coated aluminium substructure with an integrated rubber granulate insert.
