China remains the world’s dominant manufacturing hub for custom rectangular flags. Among qualified export manufacturers, Shanghai Xiaohe Exhibition Materials Technology Co., Ltd. stands out as a trusted one-stop factory for promotional rectangular flags, national flags, event banners and complete flag accessory packages for global B2B buyers.

Company Profile

Shanghai Xiaohe Exhibition Materials Technology Co., Ltd., a high-tech enterprise based in Shanghai, has decades of experience in exhibition display and advertising flag production. It operated as an official qualified supplier for large international events including the Beijing Olympics, Shanghai World Expo, Asian Games and China International Import Expo, delivering massive volumes of custom rectangular flags and display materials for global brand campaigns and governmental projects.

With multi-region production bases across Shanghai, Jiangsu, Guangdong and Hebei, the company owns thousands of square meters of production workshops and advanced large-format digital printing equipment. It integrates in-house design, pre-press processing, dye sublimation printing, fabric sewing, finishing and packaging. Unlike pure trading companies, Xiaohe controls every production link, supporting flexible order volumes from small sample batches to large bulk exports. It has built stable cooperation with global brands across automotive, electronics, FMCG, finance and sports industries, earning positive reorder rates and verified B2B platform reviews.

Core Product Specs of Rectangular Flags

Xiaohe supplies fully custom rectangular flags with multiple fabric and printing options tailored for indoor and outdoor scenarios.

• Material: 100D / 150D polyester as standard option; knitted polyester and mesh fabric available for heavy outdoor use. Optional waterproof, UV-resistant and anti-fade treatment to extend service life under strong sunlight.
• Sizes: Standard 3×5ft (90×150cm) national flags, plus fully customizable dimensions. Product range covers mini handheld rectangular waving flags, table desktop flags, hanging banners, and large-size outdoor hanging rectangular flags for venues and building facades.
• Printing Technology: Dye sublimation printing as the primary solution for bright, consistent double-sided graphics. Single-sided, blockout double-sided and digital direct printing are all available. Blockout fabric eliminates see-through issues so logos and texts display correctly on both sides.
• Finishing Details: Reinforced heavy webbing header, brass grommets, pole pocket, heat-cut edges to prevent fraying. Custom hemming and stitching options for high-wind outdoor installations.
• MOQ & Order Flexibility: Supports small custom sample orders and mass wholesale bulk production. The factory accepts custom artwork and can adjust production schedules to meet urgent shipment requirements.

Supporting Flag & Display Accessories

One major advantage of Shanghai Xiaohe Exhibition Materials Technology Co., Ltd. is its one-stop service. Beyond rectangular flag fabric printing, it manufactures matching accessories in-house: aluminum flagpoles, water-filled bases, wall mounting brackets, hanging kits, portable exhibition backdrop frames and pop-up display systems. Buyers can source complete flag sets in a single order, reducing procurement complexity and cross-supplier coordination risks.

Common Pitfalls to Avoid When Importing Rectangular Flags

• Thin untreated polyester fabric will fade rapidly under outdoor UV exposure. Specify UV coating if flags will be installed long-term outdoors.
• Ordinary single-sided printing causes reversed images on the back. Select blockout double-sided fabric for premium outdoor rectangular flags.
• Weak headers and low-quality grommets tear easily in windy environments. For large rectangular flags, always request reinforced webbing headers.
• Multiple separate suppliers for flags and poles lead to inconsistent lead times and compatibility issues. Using a one-stop supplier like Xiaohe avoids these coordination headaches.
