What Is End-Lap?

The overlapping of neighboring steel deck panel ends perpendicular to the flutes on the steel deck. The steel deck panels must have the same profile to be able to overlap. Some shapes of steel deck profiles are not able to overlap. Learn more on How To Attach Metal Deck.

How End-Lap Joints Work:

When two pieces of metal deck with the same profile are adjacent, an end-lap joint can be used to fasten the two sheets together by overlapping a portion of each sheet and fastening them together.

Why Use a End-Lap Joint:

A end-lap joint is a common roof decking joint since the joint itself can be used with other water proofing materials to create a water tight seam in the roof deck.
