Outdoor / tunnel signs and markings
Our outdoor/tunnel PL-Signs are produced with
our High Potent, SA-Pigment which DO NOT corrode in UV-Light (Sunshine),
like products produced with ZnS-pigments which will turn grey and lose their
afterglow effect after 1 year when exposed to UV-Rays. The backplate can be
produced according to the customer's needs; i.e. saltwater resistant
aluminum or acid proof stainless steel.
Contact us for more information.
These signs achieve test-results along the same lines as our indoor signs
and marking (see test-results for these).

How to compare test-results from suppliers
of photoluminescent products
Metal Safe Sign makes products for real-life applications, not for
laboratory tests. We therefore test our products in normal lighting
conditions (e.g. 25 lux) in order to make sure our products still pass the
necessary requirements for saving lives. Ask other suppliers of the same and
ask for their measurements at normal light instead of 1000 lux which is done
in the DIN 67510 measurements (the 1000 lux measurements are usually the
test-results one receives).
You will find our test-results on the specific product page.
