Relate Test:

1).Tensile Strength=1.1*Tensile Strength of Rebar (Usually more than 600Mpa)

2).Fatigue Test: After 2 million times of fatigue strength test, connection is in good condition

 

 

 

Test result: broken bar:

 

 

3. Style and Function

- End upset forging parallel thread

- Be used to link steel bar connected

- Color: According to requirement

- Can be used to joint rebar with diameter 12mm to 40mm
- Straight thread inside the adapter sleeve
- High intension of tie-in and 100% exerted grade reinforce steel bar

  connection technology guideline
- Power adaptability may fully meet varies inquires of steel bar reinforcing
  technology
- Not limited to climate, whole day construct insures time limit for a project
- Stable quality, can be measured and eyeballed at any time
- When connected, only use cannulation and spanner, don't use any energy
  source and Equipment

 

4. Product Advantage

The raw material is 45# high-quality carbon structural steel.

Strict quality control.  self-inspection, exchange inspection, sample inspection , 100% inspection

etc. reject rate

lower than 0.6%.

Tensile strength could reach 800 to 900Mpa. Normal steel,for example, HRB335,the tensile

strength reaches

500.5Mpa is OK.

Our rebar couplers are suitable for steels of different countries.

We could pack the goods according to customer's special request.

Simple to operate.

 

5. Remarks

 This kind of end upset foging parallel thread coupler can link steel bar Dia. from 12mm to 40mm.

The tensile strength of splicing can reach 1.1 times of the steel bar's. 100% reach bar break.

It widely used in key and big construction.

It meets Chinese standard JGJ107-2010,JG171-2005; American standard ACI318-2008 etc.

 

 

 

 

Application

 

   Steel Bar Thread Fasteners used to rebar mechanical splicing.

1. Steel Bar Thread Fasteners type:Paralleled type,left hand type,right hand

type,right hand left hand type and reducing type.

2.Range of application:Suitable for rebar of HRB335 and HRB400.Diameter

from 14mm to 40mm.

 

Production Process

 

 

 

packing inspection

 The rebar sleeves are packed with nilon bag.Couplers are not easy to rust.
