A welding lug is a pipe support component consisting of a single plate of varying thickness, depending upon the load, which is welded to either a supporting structure or a supported pipe and used to join other support components together using pins. Welding Lug Shown on a Constant Spring Support
Our concrete clevis plate is a method for attaching a welded beamattachment to a concrete base in place of a structural steel base.
You can use a variety of components. The most common would be astructural welding lug or a welded beam attachment. Where welding is notpermitted you can use either beam clamps or bolted plate connections such asthe clevis plate Fig. 73 or single lug plate Fig. 74.
