Full threaded steel self drilling rock bolt / Hollow anchor bar / Anchor rods The Self Drilling Anchor system is comprised of a hollow threaded anchor bar with a sacrificial drill bit that performs drilling, anchoring and grouting in a single operation. Widely used as an efficient anchoring means, in tunnel pre-support, slope, coast, mine, water conservancy projects, building foundation, roadbed reinforcement and geological diseases treatment such as landslip, crack, sink age. It`s irreplaceable in narrow construction environment. Hollow anchor bar is made of seamless tube with high strength. Advantages and Characteristics as below: 1. No casings required, because anchor bars can be drilled into loose soils without needing casings to support the boreholes. 2
The Carbon Structural Tube is a hollow section customized carbon steel tube with no welds from beginning to end. When the ring section is subjected to internal or external radial pressure, the force is relatively uniform. Using Carbon Structural Tube to make square parts can improve the material utilization rate, simplify the manufacturing process, save materials and processing time. The ASTM A106 Carbon Structural Tube has a hollow section and is used for Pipelines for conveying oil, natural...
The Carbon PrecisionTube is a hollow section customized carbon steel tube with no welds from beginning to end. When the ring section is subjected to internal or external radial pressure, the force is relatively uniform. Using Carbon PrecisionTube to make square parts can improve the material utilization rate, simplify the manufacturing process, save materials and processing time. The Precision Structural Tube has a hollow section and is used for Pipelines for conveying oil, natural gas, natural...

The fluid steel pipe is a hollow section seamless steel pipe with no welds from beginning to end. The fluid steel pipe has a hollow section and is used as a pipeline for transporting oil, natural gas, natural gas, water and certain liquid materials in large quantities. Compared with solid steel such as round steel, fluid seamless steel pipe is lighter in weight under the same bending and torsional strength. Fluid steel pipe is an economical steel, widely used in the manufacture of structural...
