If you've installed signage in Orange County for any length of time, you know the wind season. October to March, gusts hit 50–70 mph. Banners that look fine in summer will be rags in February.
Most failures we see come down to three things: wrong material, not enough grommets, and the wrong attachment hardware. Here's how we spec for wind.
Material first: pick mesh when the wind matters
13oz vinyl is the default for a reason — it's cheap and it prints great. But it acts like a sail. In sustained 30+ mph winds, even a well-grommeted vinyl banner will tear at the corners or rip the eyelets out.
Mesh banners have micro-perforations that let wind pass through. Wind load drops 30–50% depending on the mesh density. From 10 feet away the print looks identical. We default to mesh for any banner mounted to fencing or any banner installed October through March.
Grommets every 18 inches, not every 24
Default spec on most banners is grommets every 24 inches. That's fine for indoor or low-wind installs. For Santa Ana season, drop to every 18 inches. The closer the spacing, the more attachment points share the load.
Use bungee cord, not zip ties
Zip ties are rigid. Wind loads concentrate on the eyelet and rip it out. Bungee cord stretches under load and absorbs the gust. Cheap insurance. We sell bungee balls for this — ask us.
Wind slits if the banner's bigger than 4×8
Wind slits are intentional cuts in the banner that act as relief valves. For any solid-vinyl banner over 32 sqft, we strongly recommend windslits. Adds a few dollars at print time, prevents a hundred-dollar reorder when February hits.
“We had a banner up at our open house in Anaheim Hills during the February wind storm. Everyone else's signs were on the ground. Ours had bungee cord and was on mesh — still up at sundown.”

What to send us if you're installing for wind
- Mention 'wind install' in the order notes — we'll check finishing and reach out if the spec looks wrong.
- Locations: tell us if it's mounted to chain-link, building wall, freestanding pole, or truss.
- Duration: a 7-day banner gets different finishing than a 6-month banner.
