Durable Aluminum Alloy Design: This flood barrier provides a superior alternative to cumbersome sandbags. Constructed from high-quality industrial-grade aluminum alloy, it features reinforced panels and robust columns that undergo oxidation treatment for enhanced durability. Enhanced Waterproof Sealing: The water stopper panel is equipped with a concave-convex interlocking system between panels, with EPDM rubber sealing strips at each joint. A thickened waterproof strip at the base ensures a tight fit against the ground, effectively sealing connections to prevent leaks during heavy rainfall. User-Friendly Installation: These reusable flood control barriers can be quickly set up by simply placing them in the designated card slots when flooding is anticipated. One person can easily complete the installation, saving both time and effort during disassembly. Safety and Versatile Use: The flood barrier features high-visibility red-and-white reflective strips on the top panels for improved visibility at night. It is perfect for residential areas such as garages, doors, basements, and yards, as well as commercial spaces including warehouses, factories, streets, and subways. Customizable Installation Options: The flood protection baffle comes in various heights and lengths, offering customizable options. It supports three installation methods: internal, external, or a combination of both. Choose the appropriate method based on the provided images: for indoor installation, measure the distance between walls; for outdoor installation, add 20 cm to the wall distance.
