Most cost-effective rebar steel sleeve/coupler in the world
Product profile:
Straight thread connecting sleeve is used for connecting steel rebars on construction project. It mainly connect 12 - 50mm HRB335, HRB400 and HRB500 hot rolled ribbed rebars.
Main features:
(1)Products possess the ISO9001 international quality system certification.
(2)Products pass the provincial authentication. The Hebei Provincial Department of Construction approves to volume product, with production certificate.
(3)By the national construction engineering quality supervision and inspection center type inspection to confirm the qualification, and all of the joint performance can reach the I class connector standards in JGJ107 - 2010 .
(4)The rebar connecting sleeves adopt national standard 45# carbon structural steel, apply the traditional manufacturing process, with the advantage of high dimensional accuracy, reliable quality.
(5)Standard type,positive and negative thread type, different diameter type, expanding type, and the lock nut type, five series sleeve in total conclude more than 100 kinds of products, to meet all the connection requirements of any part no matter transverse vertical or obliquethe in the structure of bridge,tunnel and construction project.
(6)We can also produce welded sleeve, or according to customer requirements to design, produce other types of sleeve.
Remarks: The sleeve from our company is not marked, According to the requirements of the customer,we mark the sleeve individually. The charge of marking need to be paid alone!
:
1). rebar steel sleeve is used to connect the two rebar ends in the construction work, a new way for rebar mechnical connection with high quality and efficiency.
2). Easy Operation, saving time and rebar material. The rebar coupler producing and rebar end threading will not be affected by the weather; it can be processed before processing.
3). Use No.45 steel, with the thickness and length of the rebar coupler, the connecting part has higher tensile strength than the rebar part.
4). rebar steel sleeve can connect the rebar with the diameter 16mm to 40mm.
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

Product Advantage:
1.The raw material is 45# high-quality carbon structural steel.
2.Strict quality control. self-inspection, exchange inspection, sample inspection , 100% inspection etc. reject rate lower than 0.6%.
3.Tensile strength could reach 800 to 900Mpa. Normal steel,for example, HRB335,the tensile strength reaches 500.5Mpa is OK.
4.Our rebar couplers are suitable for steels of different countries.
Remarks:
1.This kind of end upset foging parallel thread coupler can link steel bar Dia. from 12mm to 40mm.
2.The tensile strength of splicing can reach 1.1 times of the steel bar's. 100% reach bar break.
3.widely used in key and big construction.
4.meets Chinese standard JGJ107-2010,JG171-2005; American standard ACI318-2008 etc.
