SEAMING PANELS
Note: The Magna-Loc panel system requires the use of a mechanical seamer for proper installation.
The mechanical seamer runs from ridge to eave with Magna-Loc panels laid from left to right. This
necessary seamer is designed to seam the panel clips and the vertical legs of the panel together for
weathertightness and resistance to wind uplift loads.

Pre-Crimp
Rental or purchase of the Magna-Loc mechanical seamer and hand crimpers for field seaming are the
responsibility of the installer. Mechanical seamers and hand crimpers can be acquired from Seamer Tools, Inc.
8265 Highway 178 Olive Branch, MS 38654. Phone No. (662) 895-1222, Fax No. (662) 890-4775.
Read the field manual that is enclosed in the case with the seamer. The operator should adhere to all instructions for
proper use of the seamer. Failure to follow the required instructions may result in damage to the panel and/or seamer.
Metal Sales Manufacturing Corporation will not be responsible for damage incurred by improper use of the seamer.
All panel sidelaps should be seamed with mechanical seamer as soon as possible, after the panels have been installed.
Hand crimping the panel sidelaps 8” at the eave, endlap, and ridge locations of the panel will help keep the panels in
place during normal erection, but will not prevent the panels from being blown off the roof by moderate strong winds.
Do not hand crimp panel at any clips or locations other than the ridge, endlap, and eave locations.
At endlap conditions, panels must be hand-crimped only. Mechanical seaming of panels will cause rib distortion due to
multiple thicknesses along the endlap.
Run sufficient power to the roof to operate the seamer. If the job site is a long distance from the roof or if the roof s large,
consider using a portable generator placed on the roof near the seam.
Do not overload or damage the roof with the generator unit. Be sure to follow OSHA and local electrical codes when
installing generator.
Prior to seaming panels check all seams making sure they are properly engaged. All dirt, debris, and excess sealant should
be removed from flat part of panel and seams.
