Coupler
Steel Rebar Coupler
Diameter: φ35-φ135mm
Thickness: 0.25 to 0.4mm
Color: black or galvanized
Customization: can be customized
Application: It’s mainly used as the prestressed concrete structure, such as the large span railway and highway, bridge, crane girders, rock-soil anchoring engineering, multi-floor industrial plant, coal, sports venues, etc.
The rebar coupler is made of high-quality carbon structural steel GB45 with reasonable design, advanced technology, high precision, and reliable connection quality.
We design the couplers of all specifications based on the strength requirements of HRB500 steel bars. Couplers are applicable to all screw thread steel on grade HRB335,HRB400,HRB500,HRB600.
All the performance indexes have meet meet the requirements of JGJ107-2016 grade I joints tested by National Centre for Quality Supervision and Test of Building Engineering.
It has been widely used in reinforced concrete structural engineering in various industrial and civil buildings.
Especially it is suitable for the rebar mechanical splicing in buildings and structures requiring higher explosion-proof and shock-proof and it is applied in all kinds of high-rise buildings, roads, bridges, subways, tunnels, power stations, dams, and so on.
