Rolltec®

Rolltec ®

Light and productive rebar coupler solution

Rolltec® is a rolled-parallel threaded mechanical splicing system designed for the connection of concrete reinforcing bars from Ø12 to 50 mm (ASTM #4 to #18).

Rolltec® solution is supported by a single rebar preparation equipment, which is operated by a single operator.

Rolltec® couplers comply with ACI 318, IBC 2006, BS 8110, Eurocode 2, DIN 1045, CalTrans, ASME Sec III Div 2.

 

Product features

  • A standard Rolltec® connection is made of parallel-thread rebar coupler and two bars where threads have previously been formed by cold-rolling.
  • Rolltec® bar preparation is made in sequence by a highly productive equipment which peels and form threads in sequence in a single operation. Only one man is needed to operate the machine!
  • Rolltec® threads on the rebar can be extended from a half-coupler to a full-coupler length, allowing to use the very same coupler for positional applications (no need to rotate bars to perform the connection).
