Concrete nail, commonly known as steel nail or cement nail, is made of high carbon steel, with raw material is 45 steel or 55 steel.

Production process: After wire drawing, annealing, nail making, quenching and other processes, the hard texture.

Usage: suitable for decoration industry, hard wood, light wood keel connection, brick wall and cement mortar components. It is widely used in water and electricity installation and decoration of civil and military buildings.

Performance requirements: Concrete nail has strong hardness, thick and short, besides piercing ability is very strong.

Features: Concrete nail rod has polish rod, straight grain, twill, spiral, bamboo joint and others, generally common is straight grain or polish rod.

Surface treatment: blue and white zinc plated concrete nail, mixed blue concrete nail, boiled black concrete nail (flat head), boiled black concrete nail (mushroom head), boiled black concrete nail (pan head), etc.

Advantages:Has strong hardness and good toughness. The hardness of medium carbon steel reaches above HRC50; Shear strength be equal or greater than 980 Mpa; Toughness bending degree be equal or greater than75° Performance and advantages: Super hardness, superior quality and reasonable price.

The material is made of No. 45 steel or No. 60 steel,

Production process: wire drawing, annealing, nail making, quenching and other processes, so the texture is relatively hard.
Its function is to nail some harder objects that other nails can't nail. Because the material is very different from ordinary nails, it belongs to special nails. Compared with ordinary nails, it can pierce objects more easily.
