The New Tech Machinery Panel Machine is an on-site continuous metal roofing panel roll forming machine. This machine produces Snap Lock - FF 100 with a seam height of 25 mm (1"). The panel profile varies from 305 mm (12") to 610 mm (24") wide.

On-site roll forming provides for the elimination of end laps with continuous panel forming capabilities in lengths up to nominal 46m (150').


  1. General: Metal panels employ a hidden fastening system for securement to a solid substrate. 1" Snap-Lock panels are produced with a nail strip to eliminate the use of clips and allows the panel seams to interlock without having to use a mechanical seaming device.
  2. Range of application: on wood or metal sloped roofs; in commercial, institutional, industrial and residential applications; for re-roofing or new construction.
  3. Fasteners (Screws): used to attach to plywood to be #10-12 x 25mm (1") long, pancake head, No. 2 Phillips or Robertson drive, A-point, coated steel screw. Fasteners to be spaced min. 610 mm (24") on centre fastened to plywood deck.
  4. Deck Requirements: in keeping with the Standard for Architectural Sheet Metal (ASM) Systems.






  1. Minimum roof slope is 1:4 (3" in 12"). Severe conditions (heavy snow or ice) minimum slope is 1:2.5 (8" in 12").
