Lattice girder

[1] The lattice girder was used prior to the development of larger rolled steel plates.

It has been supplanted in modern construction with welded or bolted plate girders, which use more material but have lower fabrication and maintenance costs.

The lacing elements are typically attached using either hot rivets or threaded locator bolts.

As with lattice girders, laced struts and ties have generally been supplanted by hollow box sections, which are more economic to produce with modern technology.

In some case seismic retrofit modifications replace riveted lacing with plates bolted in place.
