What does the alphanumeric code on the product mean?

The code in the format ABCDE FGHI JKL carries the complete specification of the profile: profile type, material, hardness, color, cross-sectional shape, dimensions in millimeters, packaging type and number of strands. This code allows the product to be uniquely identified and reordered. More information about product numbering.

What dimensional tolerances do extruded rubber profiles have?

Tolerances are governed by ČSN ISO 3302-1:2015 for freely vulcanized extruded products. They are standardly manufactured in precision class E2/E3 for cross-section and L2 for length — for example, for a cross-section up to 1.5 mm the tolerance is ±0.25 mm, and for a length up to 40 mm it is ±1.00 mm. More information about tolerances.

What profile shapes do we offer?

Catalogue contains over 1,500 standard profiles — letter shapes C, D, H, L, P, T and U, as well as circular, square and rectangular profiles and a range of special shapes, self-adhesive, flocked and glazing profiles, optionally with metal reinforcement.
