GB1228 Steel Structures Bolts
GB1228 Steel Structures Bolts are commonly used in critical structural applications such as Bridges, buildings and other infrastructure. Ensuring their quality is critical to the safety and structural integrity of these works. The control and traceability of the A325M heavy duty hex bolt or any fastener is a key aspect of the construction and engineering industry. Safety and structural integrity are the correct applications that distinguish GB1228 Steel Structures Bolts. Batch control and traceability help maintain the highest safety standards. Batch control ensures that the bolts used in the project come from the same production batch. This helps maintain consistent quality and ensures that all bolts from a particular batch meet the same specifications and standards. In the rare cases where defects or problems are found in a particular batch of bolts, being able to trace back to the source of those bolts can facilitate an effective recall and replacement. This minimizes downtime and project delays.

Product Description
GB1228 Steel Structures Bolts are designed for steel to steel connections. Because they are used in such a specific application, they have dimensional characteristics that are unique and limited compared to most other fastener grades. This includes stock sizes available in the market place, length tolerances, short thread lengths, and the actual head dimensions are the same as any heavy hex head bolt (Dimensions per ASME B18.2.6M 2012). AS 1252 covers high strength structural bolts used in structural steel connections. GB1228 Steel Structures Bolts have a heavy hex head, a full body diameter, and are normally short in overall length since they are connecting steel to steel. Unlike other ASTM grades,GB1228 Steel Structures Bolts is specific not only in the chemical and mechanical requirements, but also in the allowed configuration. These bolts are manufactured from a medium-carbon or medium-carbon alloy steel that is quenched and tempered to develop the desired mechanical properties.
