Quick Buying Tips

• Shanghai is a prime hub for exhibition, portable promotional signage and high-precision fabric printing, making Shanghai Xiaohe an ideal starting point if your projects focus on trade shows, pop-up activations and event branding.

• South China (Guangdong) remains the main cluster for custom illuminated storefront signs, channel letters and neon signs, with shorter lead times.

• Shenzhen is the best choice if you need digital LED signage, smart controlled RGB signs or high-tech dynamic signs.

• Ask for CE, RoHS, IP rating and aging test reports for exports to North America / Europe; UL certification is required for the US market.

• Separate your supplier selection: portable exhibition graphics, physical custom brand signs and large LED video wall displays often belong to different factory categories.
