Frequent extreme weather events have driven technological upgrades in flood barriers, with "Transformer-style aluminum alloy flood panels" emerging as a new urban river flood defense solution thanks to their modular design. Crafted from aerospace-grade 6063-T5 aluminum alloy, each panel weighs less than 20kg. Using universal connectors, they seamlessly adapt to complex terrains like bends and 15° slopes for seamless assembly.

The fully automatic hydro-powered flood barrier, requiring no electricity and operating unattended, has become a core flood prevention equipment for subways. It is currently deployed in subway stations across 16 cities including Shenzhen

In March 2025, the Chinese Society of Hydraulic Engineering released the Technical Specifications for Modular Metal Flood Barriers (Draft for Comment), establishing unified standards for the first time governing the design, installation, and acceptance of such products. The standard specifies that flood barriers are suitable for embankment heightening projects under 5 meters and urban/industrial flood control projects, with recommended single-span lengths not exceeding 3 meters. The operational temperature range spans -20°C to 70°C.

State Grid Yangzhou Power Supply Company's sixth-generation intelligent flood barrier early warning system integrates aluminum alloy flood panels with smart sensing technology and has been deployed across 12 provinces and municipalities.

surpass $14 billion by 2030, with a compound annual growth rate (CAGR) of 9.5%. The Asia-Pacific region stands as the core demand area with a 42% market share, while China, as the largest exporter, accounts for 38% of global exports.
