Steel Rebar
- -Steel Rebar is made of hot rolled rib bar. which has great anchoring effect and can be cut according to demands.
- -Steel Rebar undergoes very stringent tensile testing to ensure product quality.
- -Provide customers with a pull test for Steel Rebar after installation.
- -Usually combined with star plates, provides anchoring force for rock strata.
Steel Rebar Functions
Steel Rebar is a kind of reinforcement support method used in surface engineering such as coal mine, slope, deep foundation pit of rock and soil and underground chamber construction such as tunnel and stope.Pole into the surface of the rock mass or cavern surrounding rock mass in the drilled holes in advance, to use its head, the special structure of the rod body and tail plate blend and stability of rock mass surrounding rock and suspension effect, effect of composite beams, reinforcement effect, in order to achieve the purpose of supporting. Being used with a face plate, domed ball and nut.
Resin Bolt can be an effective rock reinforcement system for ground support.
Steel Rebar Features & Advantages
Available in left hand or right hand tread.
Suitable for using with either resin cartridges or cement grout.
Higher thread ribs mix resin better and improve anchorage.
Due to continuous thread on entire length. the nut can be fastened upward at any place. This will increase the material utilization ratio and save cost.
It has equal strength on the entire length.
Available in black or hot dip galvanized.
