Recommended Installation Procedures:
Aluminum Strut Supports
(Non-Penetrating Support Systems)
Where roof pitch exceeds 1:12 and supports are installed
perpendicular to slope, contact your MAPA Products representative
for installation alternatives.
Refe
r to project specifications when required to attach supports to
the roof membrane or deck.
Note: M
APA Products does not perform engineering design; the
structural engineer is responsible for confirming that the structure
upon which supports are installed is designed in accordance with accepted design codes and standards which allow for the
installation of rooftop equipment and piping. Further, MAPA Products shall not be liable for damage or injury caused by improper
use or installation of the product.
• Supports should be evenly spaced so that weights are evenly distributed and do not exceed the maximum
weight as outlined by its technical information in the current product catalog or as otherwise stated in the
project specifications.
• If applicable, remove ballast and/or debris from the designated support area.
• If an additional support pad is to be utilized place pad in the designated support area. If specified, adhere
support pad to roof membrane as directed by the roofing manufacturer or as otherwise stated in project
specifications.
• Place support as appropriate on either the roof membrane or centered on the support pad. Where specified,
adhere support to pad. MAPA Products recommends E-6000 adhesive.
• Place piping on the support. Single piping should be centered with multiple pipes spaced equally on the
support. In all cases, piping should be placed so that weight is evenly distributed on the support and overall
system load is balanced so as not to cause undo strain on any individual support.
• Secure piping to support as required by project specifications. MAPA accessory pipe strap or clamps may be
used to secure piping.
• Replace ballast around the support or pad as appropriate.
• Piping should be evenly spaced when utilizing bridging systems to install multiple piping runs along a common
corridor.
• Additional supports are recommended at each change of direction, branch and at each initiation and termination of the
piping run.
• Patent Pending
Supports are not intended as a platform for piping assembly.
Recommended Accessories
Natural gas piping can be suspended above the bridge utilizing accessory adjustable or fixed height roller assemblies.
Condensate lines can be mounted above the bridge with MAPA single post adjustable assemblies. Refrigeration lines
and conduits should be secured with Snap-N-Strut Clamps.
