One of the main reasons why electro galvanized barbed wire is preferred in China is due to its electro galvanized surface treatment. This treatment involves coating the wire with a thin layer of zinc, which helps prevent corrosion and rust, making it suitable for outdoor use in various weather conditions. The zinc coating also provides a shiny finish to the wire, making it aesthetically pleasing when installed as a fencing material.

Concrete nails come in various sizes, typically measured by their length and diameter. Standard lengths range from 1 inch to 6 inches, with some specialty nails available in longer sizes. The diameter usually varies from 0.090 inches (2.3 mm) for smaller nails up to 0.200 inches (5.1 mm) for larger ones.

The design of the square boat nail exemplifies the ingenuity of ancient Chinese shipbuilders. Unlike modern nails, the square shape provided a larger surface area for fastening, which significantly enhanced the durability of the boat construction. These nails were hammered in a way that ensured a tight fit, reducing the likelihood of leaks and structural failure. Additionally, the ease of production of these nails allowed for mass incorporation into shipbuilding, making them widely used across various types of vessels, from fishing boats to larger trading junks.
