Recommendations and Working Instructions

Working with Trimax® Profiles, only use hard metal tools.
Only use stainless steel fixing material.

After delivery, the material should be left bundled on a flat surface (with strapping/as supplied) until processing.

  • When cutting open (longitudinal sawing) and planing the profiles, the two opposite sides should always be cut to counteract the residual stress of the plastic and thus warping.
  • To fix our Trimax profiles to the substructure, we recommend using the 6x60mm screw for our 3x30cm plank and 6x80mm for our 5x30cm plank. Pre-drilling of the decking board is recommended (in this case a 3mm drill). The screwing should only be done with a screwdriver ratchet.
  • Larger connections, e.g. bridge coverings, can be made with hexagonal bolts or carriage bolts. Make sure that the pre-drilled holes are 2 mm larger than the screw size. Profiles longer than 4 m should be pre-drilled 3-4 mm larger. Countersunk machine screws with threaded sleeves can also be used.
  • The SL - Slip Stop System from Schmees & Lühn Holz- und Stahlingenieurbau GmbH & Co.KG makes it possible to increase the slip resistance class up to R13.
  • In addition, mounting brackets can be used for better stability and accuracy.
  • The linear expansion in midsummer is approx. 3 mm per metre of TRIMAX® .
  • Gluing of TRIMAX® profiles is not possible.
  • As with many building materials, electrostatic charging of persons is possible, which can be counteracted. With our 3x30 cm or 5x30 cm planks, metal strips (aluminium, VA, V2A or galvanised steel) can then be attached to the side of the plank, max. flush with the surface (approx. 2 cm shorter than the entire plank width). The dimensions of the strips are 2x29 mm or 2x49 mm.
    For fixing the ALU or metal profiles, elongated holes are provided in the upper third of the aluminium strips, which are then fastened with the VA special screws - 3.9 x 2.0 mm centrally in each elongated hole on the screed with screwdriver ratchet.

  • The electrostatic charge can be counteracted by the direct support of the aluminium-metal profile on the earthed metal substructure (in case of painting the discharge may not be given). Another possibility is to connect the aluminium metal profiles to each other with a wire (min. 6 mm²) and discharge them against earthed metal (e.g. also cable lug possible). A discharge against earthed metal should take place approx. every 5m.

  • When fixing our grooved or smooth planks, the screws should be inserted approx. 2-3 cm from the outer edge, on each support. I.e. in the 2nd groove. This prevents the edges from bending upwards. A slight central elevation, e.g. for bridge or bridge coverings, may have to be planned, as this improves water drainage.
  • Our Trimax profiles (e.g. stage, mooring piles etc.) are introduced into the ground by vibration or purging.
