Welded steel mill chain is a type of industrial chain that is commonly used in heavy-duty applications such as steel mills, lumber mills, and other heavy industries. It is made up of a series of welded steel links that are designed to withstand high loads and resist wear and tear.

Welded steel mill chain typically features a straight sidebar design, which provides increased strength and durability. The links of the chain are welded together at each end, which provides a more secure connection than other types of chains that use pins and cotter pins to connect the links.

Welded steel mill chain is available in a variety of sizes and configurations to meet the specific needs of different applications. It may also come with various attachments, such as extended pins or pusher dogs, to allow for the attachment of other equipment or materials.

Overall, welded steel mill chain is a reliable and robust option for heavy-duty applications that require a strong and durable chain to handle high loads and resist wear and tear.
