Reinforced couplers USES 45 # fine carbon steels is made, has threaded shape silk clasp, tooth type Angle of 75 degrees, pitch f

Product detailed description
Use 45 # high quality carbon structural production, high tensile strength, suitable for various kinds of frame structure enginee.

The detailed product description
Products with hot-rolled ribbed reinforcement for the base, the base experiment project meets GB1499.2 inspection specified in 2007, the intensity of HRB400 request, to its connection.

Connection meet the following several parts of the performance:

1. The uniaxial tensile properties

2. The high stress repeated tension and compression performance

3. Large deformation repeated tension and compression performance

Thus reach JGJ107 - the performance requirements stipulated in 2010.

 Reinforced coupler
This coupler is a bar - for connecting bar rebar connection, reinforced (14mm - 40mm).

Reinforced coupler
