Surface with matt finish (E 6), compressed with anodic oxidation. Minimum layer thickness 10 μm, layer hardness 250 - 350 HV. The all-round hard anodized surface covering makes saw cuts virtually burr-free, thereby eliminating the need for remachining. All standard Profiles and Profiles “light” and Profiles “E” feature defined points of support on the Profile exterior and inclined groove flanks. These ensure a firm and stable connection with other components. Thanks to controlled elastic deformation in the groove flanks, the fastening screw creates a vibration-free connection. Groove position, external dimensions and modular dimensions All the loading values stated in this catalogue incorporate safety factors to pro- tect against slipping and material failure. A safety factor of >2 is always applied. This means that users can make full use of the permissible values. Note: All loading values apply to static loads. Where dynamic loads are involved, the maximum values should be viewed as comparative values. Note T E C H N I C A L D A T A Tolerances Deformations such as straightness and flatness tolerance to DIN EN 12020 Part 2. Profiles not cut to size may be up to 100 mm longer than specified, due to manufacturing methods.
