Hey everyone, I’m working on a batch of yard signs for a real estate client here in Houston and I’m debating between 4mm coroplast and a thicker PVC option. Main concern is durability, especially with Houston heat, humidity, and occasional heavy rain. Some of these signs stay out for 2–3 months at a time. For those of you who’ve produced a lot of outdoor signage in hot climates: Does 4mm coroplast hold up well long-term? Is UV lamination worth it for this type of job? Have you had warping issues with PVC in high temps? Would appreciate any real-world feedback. Thanks!

Just wanted to circle back in case this helps someone else. After comparing specs and talking with a couple suppliers, I ended up sticking with 4mm coroplast for 2–3 month real estate installs. It seems to handle Houston heat reasonably well as long as it’s properly staked and not oversized. PVC looks nicer, but I did see some comments about potential warping in prolonged high temps, especially with darker prints. For anyone else working in the Houston area, I came across this local signage page that shows the common material options being offered around here (coroplast, PVC, banners, aluminum, etc.), which helped me see what’s typically used for different outdoor applications: https://alphaimprint.net/signage-houston/ Might be useful if you're comparing materials for similar projects.
