Coining is a form of precision stamping in which a workpiece is subjected to a sufficiently high stress to induce plastic flow on the surface of the material. A beneficial feature is that in some metals, the plastic flow reduces surface grain size, and work hardens the surface, while the material deeper in the part retains its toughness and .

That meant removing four ground-floor columns, three of which supported existing transfer girders. A composite steel . Steel beams are an important component in modern construction. They deliver the structural framework for bridges, buildings and industrial structures. The knowledge of different types of steel beams and their uses can help architects, contractors and engineers make better decisions about their projects. In this blog post, we will see [.]
The steel box girder bridge, because of its structural efficiency and aesthetics, has become increasingly popular as a bridge type. Because of four unfortunate erection accidents of box girder bridges in Austria, the United Kingdom, Australia, and Germany, this type of structure has received much recent attention. However, because of this attention, the behavior of steel box .The information that will be presented herein will pertain to straight and curved steel composite box girder bridges of moderate span length (50-250 ft) that are utilized for highway interchanges. Although the general theories are applicable to larger structures, the design formulas that have been developed and will be given herein are only suitable for the conventional highway bridge.Steel Girder Bridge. Girder bridges are the simplest bridge type in structure and consist of steel beams shaped to an I-section or box section, called a plate girder bridge or a box girder bridge, respectively. Girder bridges are comprised of deck slabs, on which vehicles and people pass, and of main girders supporting the deck slabs.

$\begingroup$ I've updated the question to reflect US-specificity of the data and to document the NBI explanation for the material code. In the case of girders composite with the deck I believe the structure type code reflects the girder material since the deck has a separate code (Item 107). @air - thanks for the input.

For instance, in high-rise buildings, girders work in tandem with columns and beams to form a skeleton that supports the entire edifice. . steel girders are often used in long-span bridges due to their high strength .
The American Institute of Steel Construction and the Steel Joist Institute have teamed up to create a comprehensive reference volume for rain loads and ponding design. Design Guide 40, Rain Loads and Ponding provides guidance for the design of roof systems to avoid or resist water accumulation and any resulting instability. It includes an in .Closed box girders produce a confined space once the closing plate of the box girder section has been placed during assembly. Such boxes therefore also become an issue to the steelwork contractor during fabrication and during any initial internal painting. All internal painting can be cost-effectively avoided by the use of weathering steel.
