Heavy Duty Labels for Harsh Environments

Over time, harsh environments can cause even highly durable outdoor labels to wear and fade. Prolonged exposure to heat causes materials to age more rapidly, while cold and frost heaves cause materials to contract and expand due to ground moisture. Moisture, temperature fluctuations and other outdoor factors can cause heavy duty equipment labels to lose their adhesion or become harder to read. Proper labeling of heavy duty outdoor equipment helps you and your team stay safe on the job and conform to EHS safety regulations. LEM Products, Inc., manufactures its stickers, labels, and other products using the most durable outdoor materials that can withstand extreme temperature ranges from -50°F to 250°F. Our collaborative relationships with 3M, Avery, and Flexcon guarantee the right adhesive for even the most challenging heavy duty sticker applications. Special formulations include those for adherence to corrugated, oily, slick, porous, painted, and many other surface materials and textures. Superior over-laminations protect the graphics of our permanent labels from UV radiation and moisture.

The Most Durable Permanent Safety Labels For Outdoor Equipment in Harsh Environments

When you’re labeling heavy duty equipment for outdoor use, durable and legible stickers are absolutely key. Longevity in harsh environments is important for equipment labels as well, which is why LEM Products, Inc., makes all of our labels and stickers using only the most durable adhesives and over-lamination. Temperature changes, UV radiation, and other harsh environmental factors can take their toll on outside labels and stickers, and permanent labels must be made with these factors in mind. We manufacture a wide array of permanent outdoor safety labels and stickers for different equipment, electrical identification, and a range of other purposes.
