A lattice girder, like any girder, primarily resists bending. The component sections may typically include metal beams, channel and angle sections, with the lacing elements either metal plate strips, or angle sections. The lacing elements are typically attached using either hot rivets or threaded locator bolts.
A girder (/ ˈ ɡ ɜːr d ər /) is a beam used in construction. [1] It is the main horizontal support of a structure which supports smaller beams. Girders often have an I-beam cross section composed of two load-bearing flanges separated by a stabilizing web , but may also have a box shape, Z shape, or other forms.

A rolled steel girder is a girder that has been fabricated by rolling a blank cylinder of steel through a series of dies to create the desired shape. These create standardized I-beam and wide flange beam [7] shapes up to 100 feet in length. A plate girder is a girder that has been fabricated by welding plates together to create the desired ...
The design was patented in 1820 by architect Ithiel Town. Originally a means of erecting a substantial bridge from mere planks employing lower–skilled labor, rather than heavy timbers and more expensive carpenters and equipment, the lattice truss has also been constructed using many relatively light iron or steel members.
The design is created by crossing the strips to form a grid or weave. [1] Latticework may be functional – for example, to allow airflow to or through an area; structural, as a truss in a lattice girder; [2] used to add privacy, as through a lattice screen; purely decorative; or some combination of these.
The use of laced struts within a lattice girder can be seen in the two photographs of the c1860s lattice girder bridge at Llandeilo. The first table lists these early examples. (Note that some bridges, for example the New Clyde Viaduct (or Second Caledonian Bridge) in Glasgow, appear to be of lattice construction whereas in fact the latticing ...
