Quality

Our timber is imported directly from the growth areas in Africa and South America. With our Kupfermühle planer we can provide almost any desired profile to your deck boards. By keeping the planing of our deck boards in house we can ensure that we continue to offer you excellent quality. By utilizing our Tekla drawing programme, we can send your requirements directly to our machine, saving you time by ensuring quick processing and delivery.

GL anti-slip inserts

For maximum grip on your deck we can offer you our GL anti-slip inserts. We can offer a number  of inserts per board depending on your individual needs and requirements. Our GL strips are applied by machine to ensure a constant quality. The process is as follows;

  • Mechanically applying the desired number of dovetail (shaped) grooves
  • Mechanically filling the grooves with a sand-colored, two-component epoxy.
  • Excess (mechanized) headland with clean, filtered dry sand 0.7 / 1.2 mm.
  • After the drying process the excess sand is removed

The deck board can, besides the GL-strip, also be delivered with or without a profiled upper side.
