Pittsburgh Lockformer FAQ

What is a Pittsburgh Lockformer?

A Pittsburgh Lockformer is a sheet metal forming machine that is used to create precise and durable ductwork. The machine uses a series of rolls to create a locking joint that securely connects two pieces of sheet metal together. The resulting joint is airtight, which is essential for efficient ductwork.

How does a Pittsburgh Lockformer work?

The Pittsburgh Lockformer works by using a series of rolls to create a locking joint in the sheet metal. The first roll forms a 180-degree bend in the metal, while the second roll forms a pocket that is used to secure the joint. The third roll forms a second 180-degree bend in the metal, which locks the joint in place. The result is a strong, airtight joint that is perfect for creating ductwork.

Why choose a Pittsburgh Lockformer?
There are several reasons why Pittsburgh Lockformers are the best option for creating ductwork. First and foremost, they create airtight joints that are essential for efficient ductwork. Additionally, they are extremely precise, which is important for ensuring that your ductwork fits together perfectly. Finally, Pittsburgh Lockformers are durable and long-lasting, which means that you can expect your ductwork to last for many years.
