Lock seam is a type of joint used in sheet metal fabrication that involves folding over the edge of a metal sheet to create a seam that securely connects two pieces of metal together. This process is commonly used in the manufacturing of HVAC ductwork, metal roofing, and other sheet metal products.

Key Features of Lock Seam

The lock seam joint is characterized by the folded-over edge of the metal sheet, which creates a double-layered seam that provides extra strength and stability. The interlocking design of the lock seam helps prevent air and water leakage, making it a popular choice for applications where a tight seal is necessary.

Benefits of Lock Seam

One of the main advantages of a lock seam is its ability to create a secure and durable connection between two pieces of metal without the need for additional fasteners or welding. This makes installation easier and more cost-effective, especially in large-scale projects where a high volume of seams need to be created.

Applications of Lock Seam

Lock seam joints are commonly used in the construction industry for fabricating ductwork, gutters, downspouts, and other metal components that require a watertight seal. They are also used in the automotive industry for creating body panels and other thin metal structures.

Overall, lock seam is a versatile and reliable joining method that offers strength, durability, and a tight seal for a wide range of sheet metal applications.
