Pre Punched Steel

 Proper alignment of panels is critical to insure long-term weather tight buildings system. To  assure proper alignment of all roof panels, both the secondary roof structures and roof panels of the Butler roof system are pre-punched with precisely located holes. This factory pre-punching of roof structurals and panels is a Butler exclusive that assures alignment and helps ensure weather-tightness. Improper alignment creates poor fit-up at panel splices, roof accessories, and trim connections which will eventually leak. That is why going with Butler Prepunched Structurals is best for upcoming buildings.
