How It Works

EM-BOLT® has revolutionized the connection of steel beams to concrete construction. EM-BOLT uses a pre-welded bolted connection in lieu of the field-welded connection which has been the standard up to this point. It also employs loose anchor bolts that are threaded into the embed plate after it is installed in the concrete form. This greatly reduces the labor required to install EM-BOLT in and around rebar. This feature means EM-BOLT embed plates are less cumbersome, making them easier to handle and install.

EM-BOLT’s breakthrough engineering creates a direct load transfer from the steel beam structural connection bolts to the anchor bolts in the concrete. This “bolt-to-bolt” design distributes the load evenly to all embedded anchors producing a much more reliable structural connection.

Improved Quality and Reliability

EM-BOLT improves quality, accuracy, and reliability in steel beam construction. First, AWS master welders weld the bolts in a controlled indoor environment. This allows for quality control inspection and accuracy on 100% of the welds. On an average job site, only 25% of plate welds are inspected. All EM-BOLT welds are performed in a controlled interior environment without the hazards of inclement weather, wind, ladders, scaffolding, poor lighting or awkward alignment angles, which delivers accuracy and consistency.
