1. The patented product developed by Hebei Five-Star Power Equipment Co., Ltd.—aluminum alloy water barrier, generally has a standard height of 56 cm, and the length is customized according to the actual width on site.

2. Five-Star aluminum alloy water barrier, material: the entire product is custom-made from stainless steel plate, offering high visibility and practicality!

3. Five-Star aluminum alloy water barrier, structure: the product consists of a central waterproof board, clamping grooves on both sides, and 4 expansion nails.

4. Five-Star aluminum alloy water barrier, detailed specifications: the height of the clamping groove is consistent with the waterproof board, generally 560 mm, and can be customized to 400 mm, 450 mm, or 600 mm according to customer requirements!! The thickness of the central waterproof board is about 40 mm, and the length of the aluminum alloy water barrier is determined by the specific width of the door 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, method for determining length data: the length is based on the width of the door used by the customer. 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 ±2 mm.

6. Five-Star 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 yellow and black is attached 50 mm above the waterproof board, which reflects light under illumination or other light sources, serving as a warning to personnel and facilitating entry and exit!

7. Five-Star aluminum alloy water barrier, installation method:
▲ Installation is very simple: first, thread the expansion nails through the installation holes on the clamping grooves, then fix the clamping grooves along the door frame by parallelly securing the expansion nails to the walls on both sides of the door frame. The clamping grooves are then successfully installed!
▲ During use, slide the aluminum alloy water barrier into the clamping grooves along their inner diameter, which 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, along with water-absorbing expansion bags and sandbags, play a significant role.
▲ Additionally, by installing Hebei Five-Star's water barriers and utilizing their water-absorbing expansion bags, backflow of rainwater is prevented, thereby delaying flood conditions to some extent.

Main precautions for aluminum alloy water barriers
1. How are flood water barriers made?
Answer: The manufacturing process of this flood water barrier is very simple, as they are stamped from molds, so both the appearance and surface treatment are relatively smooth,
and the surface undergoes special anti-corrosion treatment.
2. Are there any requirements for the ground when installing flood water barriers?
Answer: Generally, there are no requirements as long as the ground is not uneven. The bottom of the steel plate has a waterproof rubber strip,
so the ground does not need to be very level. If the ground is uneven,
installing the water barrier door becomes a bit more complex, requiring pre-embedding of a small steel plate to level the ground, ensuring the water barrier door is leak-proof.
