Testimonials
There are several methods for you to choose: stake mounts (for ground installation), zip ties (for chain-link fences or posts), double-sided tape (for smooth surfaces), or screws/nails (for wood or drywall). The board is lightweight, so one person can install it.
Standard boards are for indoor use. They will yellow and become brittle after 6-9 months of direct sunlight. If you need outdoor use, we recommend the UV-stabilized types. It can last 2-3 years without obvious yellowing or brittleness.
Yes, both sides are corona treated. You can print on one side or both sides. However, if you print on both sides, the ink may show through on the other side if the board is thin. For double-sided printing, we recommend 4mm or thicker.
We pack 24×36 boards in sturdy cartons. Each carton holds 25-50 sheets depending on thickness. The edges and corners are protected by cardboard inserts. This prevents damage during shipping.
