The Belo Monte Dam is a hydroelectric dam built on the Xingu River in the state of Pará, northern Brazil. Upon its inauguration, it will become the second-largest dam in Brazil and the fourth-largest in the world, with a total maximum capacity of 11,233 MW.

For this major dam project, Dextra Do Brasil continuously delivered to contractors its Rolltec mechanical rebar splicing solution between 2011 and 2016.

Rolltec is the most popular rebar splicing solution in Brazil, offering a competitive alternative to lap splices.

A total of 250,000 couplers have been used in the Belo Monte Dam, incorporated across all parts of the structure.

Rebar preparation is supported by a unique lightweight machine, which can be operated by a single person.

The Rolltec machine is relatively easy to transport and convenient to install, even in remote locations such as dam construction sites.
