Built for the Elements, Engineered for Impact

Fade-Resistant, Impact-Resistant, and Portable Performance

Outdoor signage faces a brutal environment—from intense UV sunlight and heavy downpours to high winds and active foot traffic. We don’t believe in flimsy placeholders that tip over or fade after a single afternoon. Our entire outdoor line features advanced fade-resistant printing, impact-resistant frames, and rugged, barrier-grade construction designed to keep your message standing tall and looking pristine.

SCALE EFFORTLESSLY

The beauty of portable outdoor signs lies in their flexibility. They assemble in seconds, move easily to follow the crowd, and feature interchangeable graphic tracks. Invest in a heavy-duty frame or base once, and easily update your printed inserts to match shifting seasonal campaigns, new pricing, or upcoming community events.

MAXIMUM STABILITY

From weighted water-fillable bases for windy street corners to heavy steel stakes that lock into golf course turf, we match the sign’s foundational hardware to your specific ground environment.

Tiffany Lambert

Our team chose Modern Flags to produce a custom souvenir hand flag for our recent college presidential inauguration. Excellent customer service throughout the entire process. Sue was very responsive in walking us through our options, keeping in mind our budget and timeline. When our original idea for the type of material fell through, Sue understood the vision we had for the piece and worked with us to see our design to fruition. We could not have been more pleased with the final product, a beautiful commemorative piece with an elegant look and feel. It was exactly what we hoped it would be for such an historic occasion for our institution. Thank you!

Modern Flags has been a great partner for years. They provide great work in a timely manner, and have been incredibly flexible working with me on rushed deadlines and tight turnarounds. I cannot recommend them enough!

Joe Valenti

We ordered 24 six foot silk flags from them after searching for a month for a company that could make custom shaped flags. They turned out gorgeous! Of course we were down to the wire by the time we found them. Sue and Karen were awesome to work with! They communicated quickly and efficiently and made sure we got exactly what we needed. It was kind of complicated because there were several different designs. It was a pure pleasure working with them and we couldn’t be happier with the outcome!

Frequently asked questions

Everything you need to know

Our premium A-frames and outdoor banner stands feature hollow internal chambers that can be filled with sand or water to add significant weight. Many of our large banner frames also include specialized spring-loaded bases that allow the sign to deflect wind instead of tipping over.

Absolutely. One of the biggest advantages of our portable sign systems is their interchangeable nature. You can keep your durable outer frame indefinitely and simply order fresh, affordable replacement graphics whenever your message changes.

We offer both options! Single-sided flags are printed on premium polyester where the graphic bleeds through symmetrically to the back, while double-sided flags feature two printed layers with a blockout liner so text reads correctly from both directions.
