As a leading manufacturer of anchor bolts, Colgan is here to answer your questions and concerns regarding anchor bolts and the different options we can fabricate at our facilities.
Anchor bolts are embedded in concrete and used to support structural steel columns, light poles, highway signs, heavy equipment, and many other applications. The tack welded nut / plate or hook portion of the anchor bolt creates resistance so that the bolt does not pull out of the concrete foundation when force is applied.
All Thread Rod / Epoxy Anchors
All thread rod anchors are used in post-pour applications. The anchor / threaded rod is typically inserted into a pre-drilled hole in the concrete.. The hole is then filled with epoxy that once cured, will bond the threads on the rod and the existing concrete and create a uniform holding capacity. the anchor / threaded rod is typically inserted into a pre-drilled hole in the concrete.
Wedge anchors are the option used for solid concrete and consist of an anchor body, expansion clip, nut, and washer. The anchor body is threaded and inserted into a pre-drilled hole in the concrete. The expansion clip ensures a uniform holding capacity that increases as tension are applied.
