ZTRFM 1.75” Snap-Lock Profile: Uses, Engineering- High Quality Standing Seam Metal Roofing Machine
1.75” Snap-Lock Panel & Seam Type
The ZTRFM 1.75” Snap-Lock profile is a standing seam panel featuring a standard snap-lock connection. This profile is a concealed fastener system, where roll-formed male and female legs interlock: the female leg snaps securely over the male leg, which is affixed to the roof deck using hidden clips and fasteners. One of the advantages of the snap-lock profile is that it does not require any manual or mechanical seaming during installation.
Panel Width
For the 1.75” Snap-Lock profile, our engineering design specifies a panel width of 16” for aluminum panels and 18” for steel panels. The profile requires approximately 6-1/8” of the metal coil or sheet to form the seams and edges. To estimate the total coil needed to manufacture panels in the SMI 1.75” SL profile, multiply the roof’s square footage by 1.34, providing an accurate material requirement.
Seam Height
As the name suggests, the seam height is approximately 1.75 inches.
Slope Minimum & Requirements
The SMI 1.75” Snap lock profile can be installed on roof slopes down to a 2/12 pitch, which is the absolute minimum and is dependent on the application.
Key features of standing seam metal roofing machine may include:
- Rollers:These are precision-engineered to create the specific snap lock profile accurately and consistently.
- Feeding Device:The machine typically includes a decoiler to hold the metal coil, a leveling system to ensure flatness, and a feeding mechanism to advance the material through the rollers.
- Hydraulic Cutting Device:A snap lock roll forming machine may have a flying cutoff or stationary shear to cut the formed profile into the desired lengths.
- PLCControl System: Modern roll forming machines are often equipped with computerized control systems for precise adjustment of roller positions and machine parameters.
- Tooling: The machine may require different sets of tooling (rolls) to produce various snap lock profiles.
