The PunchLok® II System offers a faster and efficient installation solution for high-performance steel roof decks. Its advanced mechanical sidelap connections replace traditional welding, reducing labor costs and installation time. This system uses a specially designed pneumatic tool to create a high-quality crimp in the interlocking sidelaps of a variety of roof deck profiles.
With superior diaphragm shear strength and wind uplift resistance, PunchLok II increases durability for large-scale commercial and industrial roofs, making it the ideal choice for projects in seismic and wind-prone areas.
Cellular steel roof deck combines structural strength with aesthetic appeal. Featuring a flat underside and integrated utility space, it’s perfect for open-ceiling designs in offices, schools, and retail spaces. Its enhanced long-span capabilities, acoustical properties, and fire resistance make it suitable for large commercial buildings, stadiums, and industrial facilities.
With superior diaphragm shear strength, cellular decks are built to handle heavy loads and resist wind and seismic forces, while offering a clean, polished look. Enhance your project’s performance and aesthetics with cellular steel roof decks.
Designed for sound control in buildings, acoustical steel roof decks feature perforated panels and sound-absorbing insulation to reduce noise transmission. These decks create quieter environments without sacrificing strength or fire resistance and are ideal for spaces where acoustical performance is critical, such as schools, theaters, and healthcare facilities.
Optimize your building’s acoustics and structural performance with acoustical steel roof deck solutions.
Interlocking Side-lap connections have a male side underneath that is high enough to reach the top of the female side above and are attached with either a top seam weld or PunchLok II.
Interlocking Side-laps for Screw Connections attach using a screw installed at the low point where the male and female sides meet, with the bottom piece overlapping underneath.
Verco’s exclusive PunchLok II System makes use of a specially designed pneumatic tool that requires no welding, installs up to 10 times faster than top seam welds, requires no touchup from top or bottom of the deck, and can be visually inspected without special tools or gauges.
Nested Connections have overlapping pieces that nest into each other, allowing the deck to shift left and right for the perfect fit before final screw or weld connections are made.
