What Is Punchlok?

What is Punchlok?
Punchlok II is a metal deck system that has the highest diaphragm shear values, requires less welding, and reduces the steel deck gauge. It's the evolution that replaced top seam welds. Punchlok II is essentially normal metal decking, but the side lap is attached with a Punchlok II tool instead of a button punch.

The PunchLok II tool is a pneumatically operated, hand-held, tool that joins metal decking sidelaps of the PunchLok II system.

This is a patented system and it can only be used on Verco or Vulcraft metal decking. Punchlok II is the second generation of this system in which the latest tool redesign has larger jaws and is more efficient. It replaced the original Punchlok metal decking. Verco Punchlok II is normally specified on the West Coast and Vulcraft Punchlok II is specified throughout the remainder of the country.

What Is A VSC2 Sidelap Attachment?
When you use a Punchlok II tool to crimp the sidelap of Punchlok II decking it's called a VSC2 which stands for Verco Sidelap Connection Version 2. The VSC2 connection improves the shear values of the decking when compared to a typical button punch side lap. These factors create an opportunity to lower labor and material costs.

Punchlok Roof Decking
Punchlok II metal decking is primarily used for metal roof deck applications. The main benefit of this system is the greater shear values created by the VSC2 side lap connection. Increased shear values apply to a roof deck condition and NOT a floor deck condition.

Punchlok II is not a weather tight system. When the tool fastens the side lap it will penetrate the material and it will leak 100 percent of the time. It is intended to be used in an application in which a built up roof will be installed over the metal decking.

Can you use Punchlok II on a Canopy?
You should NOT install Punchlok II metal decking for a canopy. Canopies are designed to be as weather tight as possible. You can see from the image below that Puncklok II will leak at the side lap connection. If you have a canopy installation you should use button punch side lap metal decking such as: HSB-36, N-24, or HSN3

Can you use Punchlok II as a composite floor deck?
Punchlok II floor deck is fine to use in a floor deck application, but there are minimal benefits when compared to a button punch side lap. The main benefit when using Punchlok II instead of button punch is the consistency of the side lap connections. However, it is NOT important enough that it should change what type of metal deck is specified. What normally happens when Punchlok II is specified on a job is that the engineer is familiar with the Punchlok II system and by default everything that they specify becomes Punchlok II. I would NOT recommend using Punchlok II floor deck on a small job.
