The general specification height of the aluminum alloy water barrier is 56CM, and the length is customized according to the actual width on site.2. Five-Star aluminum alloy water barrier, aluminum alloy water barrier material: This product is entirely made of customized stainless steel plate, with high visibility and practicality!3. Five-Star aluminum alloy water barrier, aluminum alloy water barrier structure: This product consists of a central barrier plate, clamping grooves on both sides, and 4 expansion nails.4. Five-Star aluminum alloy water barrier, aluminum alloy water barrier detailed specifications: The height of the clamping groove for the aluminum alloy water barrier is consistent with the height of the water barrier, generally 560mm. It can be customized to 400mm, 450mm, or 600mm according to customer requirements!! The thickness of the central barrier plate is about 40mm. The length of the aluminum alloy water barrier is determined by the specific width of the door where it will be used! Each set of Five-Star aluminum alloy water barrier comes with 4 expansion nails required for installation.5. Five-Star aluminum alloy water barrier, aluminum alloy water barrier method for confirming length data: The length of the aluminum alloy water barrier is determined by the width of the door where it will be used. When placing an order for customization, the customer needs to accurately measure the width of the walls on both sides of the door, with an allowable error of ±2mm.6. Five-Star aluminum alloy water barrier, aluminum alloy water barrier surface treatment: The surface of the water barrier is treated with anti-corrosion, making it hard and aesthetically pleasing. A reflective strip in alternating yellow and black is attached 50mm above the barrier plate, which reflects light under illumination or other light sources, serving as a warning to people and facilitating their entry and exit!7.Five-Star aluminum alloy water barrier, aluminum alloy water barrier installation method:▲ The installation of the aluminum alloy water barrier is very simple. First, thread the expansion nails through the installation holes on the clamping grooves, then fix the clamping grooves on both sides parallel to the door frame onto the walls on either side of the door frame using the expansion nails. The clamping grooves are then successfully installed!▲ When in use, slide the aluminum alloy water barrier into the clamping grooves along their inner diameter. This can also help prevent rats from entering! When not in use, remove the aluminum alloy water barrier. The clamping grooves fixed on the wall do not affect the normal opening and closing of the door.▲ Hebei Five-Star's aluminum alloy water barriers, water absorption expansion sandbags, and other items have played a significant role.▲ Additionally, by installing Hebei Five-Star's flood barrier water barriers and utilizing the water absorption expansion bags produced by Hebei Five-Star, backflow of rainwater is prevented, thereby delaying the impact of rain and flood conditions to some extent.Main precautions for aluminum alloy water barriers1. How is the flood barrier water barrier made?Answer: The manufacturing process of this flood barrier water barrier is very simple. It is all mold-pressed, so both the appearance and surface treatment are relatively smooth.The surface has also undergone special anti-corrosion treatment.2. Are there any requirements for the ground when installing the flood barrier water barrier?Answer: As long as the ground is not uneven, there are generally no specific requirements. The bottom of the steel plate has a waterproof rubber strip.The ground does not need to be very level. If the ground is uneven,then installing the water barrier door becomes a bit more complicated. A small steel plate needs to be pre-embedded to level the ground, ensuring that the water barrier door is leak-proof. more>
