advertising flags concave

Our advertising flags concave combine a lightweight modular pole with a curved fiberglass top section and custom-printed feather-shaped graphics, creating a highly visible solution for outdoor branding, promotions, events, and roadside advertising.
The pole uses a fiberglass top section with a fishing-rod-like tapered design. It is thinner at the top and thicker at the bottom, allowing the upper section to flex smoothly in the wind while helping the flag maintain an attractive flowing shape. The lower sections are plug-in aluminum tubes. When multiple aluminum sections are used, each section gradually increases in diameter from top to bottom. Cast-aluminum female sockets are pre-fixed into the lower tubes, allowing the upper aluminum tube or fiberglass section to insert directly into the socket for fast and secure assembly.
Five pole sizes are available:
Model Pole Height Flag Size
S 6.6ft / 200cm 1.6 × 5ft / 50 × 150cm
M 9.2ft / 280cm 1.8 × 6.6ft / 55 × 200cm
L 11.2ft / 340cm 2 × 8.5ft / 60 × 260cm
XL 14.9ft / 455cm 2.6 × 11.2ft / 80 × 340cm
XXL 18.4ft / 560cm 2.8 × 14.8ft / 85 × 450cm
The complete system is available with seven base options, including ground spike 60, ground spike 60 with bearing rotation, cross base tube 60×80 with basic rotation, cross base steel 40×60 or 60×80 with basic rotation, and cross base steel 40×60 or 60×80 with bearing rotation. Select the base according to the installation surface, pole height, and expected wind conditions. Taller poles and stronger winds generally require a larger and heavier base, and a water tank can be added when extra ballast is needed.
The graphics are produced using direct digital dye-sublimation printing on lightweight flag fabric, typically 110g. The complete graphic has a feather-like profile, while concave refers specifically to the concave-shaped bottom edge of the flag.
For single-sided graphics, the design is printed on one layer of flag fabric. For double-sided graphics, two layers of fabric sandwich a black inner layer. This construction helps prevent the front-side artwork from showing through to the reverse side, providing better visual separation and more consistent branding from both directions.
These outdoor flags for advertising are suitable for storefronts, exhibitions, sports events, promotions, parking areas, retail locations, roadside campaigns, and other high-traffic outdoor applications. With custom graphics, multiple sizes, and interchangeable base options, they offer a flexible solution for businesses looking for flag signs for advertising.
