Custom Block Flags for Outdoor Advertising Display
Block Flags: Versatile Rectangle Flags for Outdoor Promotions
Looking for a powerful way to grab attention at events, storefronts, or trade shows? Block flags, also commonly known as rectangle flags, offer one of the most effective solutions for outdoor branding and promotions. With their clean, rectangular design and high visibility, block flags are ideal for showcasing logos, slogans, and custom graphics in a professional and eye-catching way.
What Are Block Flags?
Block flags are vertically-oriented rectangular advertising flags designed to stand tall and steady in various outdoor environments. Unlike curved feather or teardrop flags, block flags provide a larger printable area, making them perfect for displaying bold messages or detailed artwork. Their shape allows for a more "banner-like" look, ensuring your promotion stands out from a distance.
Block flags are especially popular among:
- Retail stores looking to attract foot traffic
- Outdoor events and festivals
- Trade shows and promotional booths
- Sporting events and roadside advertising

Strong, Weather-Tested Materials
When it comes to outdoor displays, durability matters. Our block flags use high-performance materials built to withstand wind, sun, and rain:
-
Flag Fabrics: Choose between Warp Knitted Fabric or Polyester Pongee, both available in single-sided or double-sided printing options.

Wind Resistance: All flags are tested in a
160km/hwind tunnel in Italy, ensuring they can handle harsh weather without damage. - Color Printing: We use high-quality sublimation printing to deliver vibrant, sharp graphics that retain color through regular outdoor use.
Whether placed on a street corner or in front of an exhibition booth, these flags maintain their visual impact even in challenging conditions.
4-in-1 Pole System Compatibility
One of the most innovative features of our flag solution is the 4-in-1 pole system. With a single set of poles, you can easily switch between four different flag shapes:
This modular system is ideal for clients who run frequent events or promotions. Instead of purchasing four separate kits, you can use one base pole system and simply change the flag surface as needed. This approach saves storage space, cost, and time.

Our block flags are compatible with a variety of base options, allowing you to install them securely on different surfaces:
- Water-filled bases for stability on concrete or asphalt
