Test Protocols

How Does Our Testing Set Us Apart?

We test our products on a full range of roof gauges geometries, dimensions and materials. Using a third-party, ISO 17025 accredited lab, our tests determine the ultimate load-to-failure results on hundreds of profiles to ensure performance. These rigorous tensile load tests run in two load directions: normal-to-seam testing (pulling-up), and parallel-to-seam testing (drag load).

Our tests are divided into the two metal roofing profiles below.

Standing Seam

Exposed-Fastened

CLAMPS FOR STANDING SEAM METAL ROOFS

Tensile Pull Test (Load Parallel-to-Panel Seam) for Snow Guards

This testing involves pulling the S-5! product along the seam to demonstrate drag load.

SIGNIFICANCE IN USE:

This test protocol outlines methods of testing S-5 brackets that are designed for panel sheeting only attachment or S-5 brackets that are designed for composite assemblies.

BRACKETS FOR EXPOSED-FASTENED METAL ROOFS

Tensile Pull Test (Load Normal-to-Mounting Surface of S-5 Bracket) for Solar and Light-Duty Applications

This perpendicular (pull-up) testing assesses the S-5! product's connection to the roof vertically.

To perform this testing, the following elements are required:

(Click through the tabs below for further explanation.)

SIGNIFICANCE IN USE:

S-5 brackets are used in a variety of applications on metal roofs to facilitate the mounting of ancillary equipment and accessories. Users wish to quantify the strength of the bracket’s attachment with loads acting in a negative normal direction to the roof’s surface. This test protocol outlines methods of testing to determining ultimate failure loads that are introduced to the bracket’s mounting surface in a load direction that is (negative) normal to roof surfaces.

 

There are two possible scenarios: S-5 brackets that are intended for installation on metal panel sheeting only, or S-5 brackets that are intended for installation on composite assemblies consisting of the panel and supporting deck or other structural element when the bracket attachment extends into the supporting element. The test isolates the point of failure to the S-5 bracket and its attachment. Other elements of possible load chains including the panel’s buckling capacity are not evaluated.
