aluminum, brass, or stainless steel. Alternatively, black characters can be screen printed on construction-grade yellow or sliver reflective sheeting for use on metal reflective pole tags, making them durable, and UV stabilised. For confined spaces where close up reading is required, designs can comprise miniature markers with raised, 3D characters, called FastTags - these will remain legible in low light, oily, or dusty environments. The raised, 3D characters are hot stamped with high quality UV stable foil and are nonconductive and non-corroding.
Utilities that opt to use innovative products designed to last for many decades can significantly improve safety and uptime,
while reducing potential liability and litigation risk

Everlast by Tech Products
Everlast by industrial ID product manufacturer, Tech Products, is an example of durable signage. The product is made of thick, high impact polyolefin plastic with copy and pictograms permanently embedded through the thickness of the substrate. The polyolefin plastic is impervious to sun, wind, rain, humidity, salt
water, and temperature variations as well as fumes and acid or alkaline solutions. The characters can be seen from a distance and are sharply contrasted. The signage can be cut, scratched, even shot through with little or no effect to the embedded characters, according to the company, which helps to ensure readability decades later. Another effective way of creating permanent signage is to use embossing that creates raised characters in metal materials to improve legibility even when covered in dust, dirt, or paint. Tech Products performed numerous durability tests on the signs
in compliance with UL and ASTM standards. When the signs were subjected to the equivalent of 43 years of UV exposure, salt spray, vibration, abrasion, and temperature variation, the test results showed no change in color or legibility.
AVOID REPLACEMENT These products will remain valuable tools even as new technologies such as geographic information systems (GIS) and global positioning systems (GPS) are employed. And although pole tags are not mandated by regulations, many utilities use them to assist with recovery efforts after a regional outage by posting serialised GIS or GPS pole marking and numbering that correspond with a pole’s geographic location. During emergencies like hurricanes, mutual aid situations often arise where utility trucks from different regions are called on for assistance. These trucks may not have access to GIS or GPS location information, making pole tags essential for proper identification and location guidance. ●
