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

The detailed product descriptionProducts 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 couplerThis coupler is a bar - for connecting bar rebar connection, reinforced (14mm - 40mm).
