OVERVIEW

The Knudson KR-12 is an on-site continuous panel metal roofing machine. Panel profiles vary from 300 mm (12") to 500 mm (20") wide with a seam height of 38 mm (1 1/2"). Panels are produced with two stiffening flutes.

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

SYSTEM DESCRIPTION

  1. General: Standing seam panels employ a hidden fastening system for securement to a solid substrate. Panels are seamed together with a mechanical seamer.
  2. Range of application: On wood or metal sloped roofs; in commercial, institutional, industrial and residential construction; for re-roofing or new construction.
  3. Fasteners (Screws):
    1. Wood Decks: Fasteners to be #10 x 22 mm (1") long pancake head type A plated.
    2. Steel Decks: Fasteners to be #8-16 x 22 mm (1") long self-drilling, self tapping wafer head, plated screws.
  4. Panel Clips:
    1. Wood Decks:
      • Panel clip to be Knudson 22 ga one piece assembly 87.5 mm (3 1/2") wide 47.6 mm (1-5/8") high. One panel clip spaced at 762 mm (30") on centre. Two fasteners per panel clip used, inserted into panel clip guide holes. Fasteners to be #10 x 22 mm (1") long pancake head type A plated.
      • Two piece assembly to be used for longer panel lengths, clip to be Knudson 22 ga 87.5 mm (3 1/2") wide 47.6 mm (1-5/8") high. One panel clip spaced at 600 mm (24") on centre.
    2. Steel Decks:
      • Panel clip to be Knudson 22 ga one piece assembly 87.5 mm (3 1/2") wide 47.6 mm (1-5/8") high. One panel clip spaced at 600 mm (24") on centre. Two fasteners per panel clip used, inserted into panel clip guide holes. Fasteners to be #8-16 x 22 mm (1") long self-drilling, self tapping wafer head, plated screws.
