Construction Materials

Introduction to Steel Rebar Steel rebar (reinforcing bar) is a ribbed steel bar used to reinforce concrete and masonry structures, enhancing tensile strength and preventing cracks under load. As a critical component in construction, rebar ensures the durability and safety of infrastructure such as bridges,

Introduction to Grouting Pipes Grouting pipes, also known as steel sleeve pipes, perforated grouting tubes, or injection pipes, are essential components in geotechnical engineering, foundation reinforcement, and underground construction. These pipes feature strategically placed perforations or slots to allow controlled grout injection, enabling soil stabilization,

Hollow anchor bars, also known as hollow anchor rods or hollow rock bolts, are critical components in geotechnical engineering and underground construction. These specialized steel bars feature a hollow core design, enabling simultaneous functions such as grout injection, tensioning, and drainage. Widely used in tunneling,

Hollow anchor bars are a type of support material used in geological engineering, mine support, tunnel construction, slope stabilization and other projects, with a self-drilling function. Its main function is to strengthen the structural stability of rock formations and soil and prevent collapse. Compared with
