We have talked a lot about threaded rebar coupler in the past, but less about   weldable rebar coupler . We will introduce you some about weldable rebar coupler here, what is a weldable rebar coupler and where is it used? The weldable rebar coupler is the steel bar connecting sleeve between rigid steel columns, which is used for the steel bar connection construction between large steel columns and frame beams. 1. The weldable rebar coupler is made of No. 45 high-quality carbon structural steel, it has some advantages like reasonable design, advanced technology, high dimensional accuracy and reliable connection quality.  2. The basic parameters of weldable rebar coupler are designed according to the strength requirements of HRB500 steel bars, which are applicable to HRB335, HRB400, and HRB500 rebars.  3. The performance indicators of the weldable rebar coupler have been tested by the "National Construction Engineering Quality Supervision and Inspection Center", and all mee...

Straight thread sleeve   is used for mechanical joints to transmit axial tension or pressure of steel bars. Straight thread sleeve is divided into direct rolled straight thread sleeve, stripped rib rolled straight thread sleeve and upsetting straight thread sleeve. Material requirements for straight thread sleeve: 1. Straight thread sleeve should be made of round steel or seamless steel pipe with grade 45, and its mechanical properties and chemical composition should meet the requirements of GB/T 699, GB/T 8162 regulations. Other steel materials can also be used, and their mechanical properties should meet the requirements of the corresponding national or industry standards and be confirmed by type inspection. 2.  For sleeves that need to be welded with steel such as structural medium steel, the material should meet the weldability requirements.

In the construction industry, steel bars are used widly, and it is well known that the length of steel bars is limited. Sometimes the construction need long steel bars, and welding technology cost a lot on time-consuming and laborious. In this case, the rebar connection sleeve is a good choice. Let's take a look to know why are rebar connection sleeves popular in customer? Now, the  rebar connection sleeve  is a new product that replace the traditional welding method. The rebar connection sleeve can stall without electric, and it takes the international standard No. 45 steel material, which makes itsuper hard and ensures the firmness and stability of the product during use. The rebar connection sleeve is exquisitely designed, and the precision of each product is very high. Moreover, use rebar connection sleeve is much environmentally friendly that it does not use open flame operations, which improves the safety and effectiveness of engineering construction.  There are man...

Rebar coupler systems, sometimes also known as mechanical splices, are usually used as an alternative to traditional steel bar connections in construction. Rebar couplers can be divided into first-grade steel, second-grade steel, and third-grade steel according to their tensile strength, compressive strength, and other properties. What is the grade classification standard of rebar couplers, and what is the difference between different grades of rebar couplers?  1. The  rebar coupler  whose tensile strength is greater than or equal to 1.1 times the ultimate tensile strength of the steel bar is the first-grade rebar coupler. The first-grade rebar coupler has better tensile performance and is suitable for parts requiring higher tensile strength.  2. A rebar coupler whose tensile strength is greater than or equal to the standard value of the ultimate tensile strength of the steel bar is a second-grade rebar coupler. The tensile performance of the second-grade rebar coup...

Rebar couplers   are employed in reinforced concrete cement structures to change the system of lapping & welding in reinforcement. Couplers are employed where the long length of the bar is required or when connecting the additional bars to the end of existing bars are connected by wire next to each other. Some benefits of the coupler in reinforcement are as follows: a. It has excellent quality control & is easy to handle. b. The load transfer is reasonable. c. The coupler does not make congestion. d. The continuity load path is valid. e. The rebar coupler is very economical compared to all the systems of joints in reinforcement. f. The Coupler expands the work speed by short installment. g. The connection check is easy & simple. h. It enhances the service of the bar by not wasting bars like the lapping. i. The coupler decreases the lapping length analysis. j. It enhances structural integrity.
