Concrete or Plastic spacers are little accessories used to maintain the position of rebars in the concrete structures before pouring the concrete. This is necessary to maintain a clear distance (cover) between the surface of the concrete and the rebar, …

Starter bars are rebars cast into the concrete to give a lapped connection to provide continuity of reinforcement across a cold joint or construction joint. Planted horizontally to the existing concrete element in which they are installed, they are also used to extend …

An Industrialized Building System (IBS) refers to a technique of construction whereby components are manufactured in a controlled environment – either onsite or offsite – placed and assembled into construction works. The term IBS is often tossed around in the …

Lapping of rebars has long been considered an effective, economical splicing method, but today’s more demanding concrete designs are forcing builders to consider alternatives. In almost all reinforced-concrete structures, rebars must be spliced. The required length of a bar may …
