Used to fix and connect reinforcement rebar in the reinforced concrete site, drilled RB internal thread, hot dip galvanized and made from hex steel bar 4.8 gr. to 8.8 gr.
Hexagon reinforcing bar couplers are made of solid carbon steel bar tapped with RB thread or other internal thread, according to the different strength requirements of the usage place, they can be made from grade 4.8 to grade 8.8. The surface treatment is hot dip galvanized, which greatly enhances the corrosion resistance and rust resistance of the product.
In the construction site of reinforced concrete, it is an appropriate way to connect the reinforcement bar, which can simplify the design and construction of reinforced concrete and reduce the amount of reinforcement required. In many large-scale infrastructure and multi-storey construction projects, construction workers use mechanical couplers. When the large diameter rebars used in the concrete components are usually overlapped with the small-diameter rebars, the amount of use is more than a certain ratio of the single rebars. Therefore, overlapping cannot be avoided. Considering the crowding and economy of steel rebars, it has been considered as an effective and economic splicing method to provide mechanical couplers.
Mechanical rebar couplers are a mechanical connection between two pieces of reinforcement, which makes the performance of reinforcement similar to the continuous length of reinforcement. Mechanical joints end-to-end connection of reinforcement provides many advantages of continuous reinforcement. Many years ago, arc welding was the only way to achieve continuity. Today, the continuous maturity of mechanical joint technology can ensure that an accurate and reliable connection operation can be made quickly and easily.
