Common hook and loop tape material has been used for many years to provide a removable fastner for materials. However, the typical material do not perform as well when exposed to heat and aggressive chemicals. In our own shop, we have found that pressure sensitive hook and loop does not hold well to powdercoated metal either over the long term.
In the mean time, textiles and other substrates have advanced to be able to withstand extremes in weather and exposure. To try to resolve this gap, I came across an interesting product called Metaklett which is basically hook and Loop made from Steel. This could provide some intriguing options for long term and outdoor applications where the flexibility of Hook and Loop is needed with more strength.
What would happen if you mechanically fastened this material to metal tubing? Could you add another rigid substrate to the other side easily? Would the look side work with a softer loop material or vice versa?
