Concrete Nail, commonly known as steel nails, are a type of nail made from carbon steel. They are made of 45 or 60 steel and processed through processes such as wire drawing, annealing, nail making, and quenching, resulting in a relatively hard texture. Its function is to nail on some relatively hard objects that cannot be nailed with other nails, because the material is very different from ordinary nails, it belongs to specialized nails. Cement nails have high hardness, are coarse and short, and have strong piercing ability. There are various types of nail rods for cement nails, including sliding rods, straight lines, diagonal lines, spirals, bamboo knots, etc. The most common ones are straight lines or sliding rods.
According to different classification methods, cement nails can also be divided into: blackened cement nails, bluened cement nails, colored cement nails, countersunk cement nails, K-shaped cement nails, T-shaped cement nails, galvanized cement nails, and so on.
