Anchor Bolts

05 May 2015

In a pre-engineered steel building system, anchor bolts are what hold the steel structure to the concrete foundation.

The anchor bolts are embedded in the concrete and the steel (external load) is fastened to the anchor bolt. Anchor bolts are used at each steel column and at each door jamb. An anchor bolt has a threaded end that is used to bolt the external load with a nut and washer. The embedded end of the anchor bolt has either a hook on the end or a welded nut and washer. This gives the anchor its strength when the concrete cures around it.

The grade of steel used for anchor bolts in a pre-engineered steel building application is very important and is always specified by the building supplier’s engineers as the steel strength and brittleness are keys to the steel building design.
