Although there is a reduction in cross-sectional area, it is longer in length and transfers load on more number of threads. It is also a straight threaded coupler and is very quick and easy to install. It qualifies ACI 318 and BS 8110 requirements for mechanical splicing. It is a Type-I Mechanical Splicing.   Operations Couplers Manufacturing of couplers is done on CNC machines in our fully mechanized factory and will be sent readymade as per requirement. Threading to Rebar Threading onto the rebar is done at the project site with our machineries installed and operated by SLDI. It involves: Cold Rolling the Rebar In this operation, the rebar is cold rolled to remove the ribs and to get a uniform surface for threading. Threading After rolling, the rebar is threaded to the specified pitch on a threading machine.   Features Length of coupler is more compared to forged one. Higher productivity at site in a day's shift. Compact threading machine; less space required. Less power consumption. Easy to install parallel threading. Tensile strength is more than lap splices. Rebar threads are straight and will pass Go & No-Go Ring Gauge test. Qualifies Type-I Coupler requirement. Joint should be in Lap Zone. http://www.sldjinustries.in/20mm-parallel-threaded-coupler.htm http://www.sldjinustries.in/20mm-parallel-threaded-coupler.htm Mon, 29 Jun 2026 00:00:00 +0530 Description SLDI-ROLL is one of a type of parallel threaded coupler for rebar splicing in Civil Construction projects.

Unlike inclined or tapered couplers, which require high precision, skill, and constant supervision, it has straight threads and is very quick and easy to install. It qualifies ACI 318 and BS 8110 requirements for mechanical splicing. In forged type of threading, the cross-sectional area of the rebar does not reduce, as it does in rolled or tapered threading. The density of the rebar is increased by applying lateral forces at the tip of the rebar. Threading is then processed, and hence there is no reduction in the diameter of the rebar.   Operations Couplers Manufacturing of couplers is done on CNC machines in our fully mechanized factory and will be sent readymade as per requirement. Threading to Rebar Threading onto the rebar is done at the project site with our machineries installed and operated by SLDI. It involves: Forging/Upsetting Rebar In this operation, a lateral force is applied at the tip of the rebar, which in turn increases its density and diameter. Threading After forging, the rebar is threaded to the specified pitch on a threading machine.   Features Easy to install parallel threading. No reduction in rebar diameter. Tensile strength is more than lap splices. Less supervision; even a hand-tightened joint is safe. Rebar threads are straight and will pass Go & No-Go Ring Gauge test. Qualifies Type-II Coupler requirement. Good for structures undergoing inelastic deformations during an earthquake. http://www.sldjinustries.in/20mm-cold-forged-parallel-threaded-coupler.htm http://www.sldjinustries.in/20mm-cold-forged-parallel-threaded-coupler.htm Mon, 29 Jun 2026 00:00:00 +0530 Description SLDI-FRGD is the most widely used form of coupler for rebar splicing in Civil Construction projects.
