Hot Rolled Deformed Bars

Product Description：

Our Hot Rolled Deformed Bars, also known as Deformed Bar Steel or Deformed Reinforcing Bar, are superior reinforcement products widely used in construction projects. These bars are produced by hot rolling process, ensuring high strength and excellent ductility. The unique deformations along the surface provide enhanced bonding with concrete, increasing the overall structural stability and load-bearing capacity of the reinforced concrete elements. The ribbed pattern of the Deformed Bars allows for improved adhesion and mechanical anchoring within the concrete structure, reducing the risk of slippage or displacement. With their reliable performance and superior quality, Hot Rolled Deformed Bars are essential components for ensuring the safety and longevity of various construction applications.

Product Parameters

Left-handed Resin Anchor Overview:

Left-handed resin anchor is a kind of high-strength, structurally sound support material, which can effectively restrain the surrounding rock, automatically adjust the direction of force, and has a high preload force. It is suitable for high-strength support work of large deformation roadway such as highland pressure mine. In addition, the left-handed resin anchors can be widely used in different projects such as railroads, water conservancy, etc., providing a reliable guarantee for high-strength roadway support. Mechanized and fast installation is an advantage that other types of support materials do not have.

Left-handed anchor bar features:

Left-handed anchors are characterized by high strength, reasonable structure and large preload force, which can automatically adjust the direction of force and enhance the binding force on the surrounding rock. Its mechanized and fast installation attributes make it an ideal choice for high strength support of large deformation roadway. Left-handed anchor rods can be end-anchored, lengthened and fully-anchored, and are suitable for use in projects such as high-ground pressure mines, and can also play its role of high-strength, long-lasting support in the field of railroads, hydropower and other projects.

Working Principle:

The working principle of longitudinal ribless rebar type resin anchor is to realize the firm bonding with coal rock through the combination of metal rod body and matching resin anchoring agent. According to the design needs, the anchor rods are inserted into the holes soaked with anchoring agent, and after curing by chemical reaction, a firm connection is formed. By adding protection net and tray and using nuts to tighten the anchors, the support function is realized, which stabilizes the roof plate, adapts to the rock movement, and effectively prevents the phenomenon of leaving the layer. This prestressed support system can improve the safety of support, realize mechanized installation, effectively solve the problem of roof stabilization, and ensure construction safety.

Longitudinal ribless rebar type resin anchor metal rod body use and installation:

1. Determine the position of the anchor according to the design requirements and make holes in the drilling machine.

2. Remove the rock chips in the hole using the pressurized wind machine.

3. Feed the anchoring agent into the bottom of the hole and use the anchor rod to fix the position and start mixing (the mixing time is specified according to the anchoring agent). After completing the mixing, dismantle the mixing equipment, wait for the specified time, remove the mixing connector, and install the anchor disk, ball washer, friction washer and nut. Finally, tighten the nuts using a special wrench.
