Trex Fencing Wind Load Testing

When Trex Seclusions® wood composite fencing was first brought into production in 2005, Trex® wanted to make sure that they had a more superior product to the common dog-eared composite fences that were being manufactured. In March of 2009, the Trex Company sent their fence product to York, PA to have it tested for its Miami-Dade wind load capacity.

The setup included a steel fixture to simulate an embedded rigid post. The bottom rail was a standard 2” from the ground. The panels tested were 6’ high by 8’ wide and the posts are 5” x 5”. The fence was assembled by the testing company Architectural Testing at their York, PA campus.

In the test, wind speeds started out at 75mph for 50 seconds, then reduced to zero for one minutes to check for recovery. Recovery is the distance the panel, pickets, posts, and rails move from having the wind blowing against it, to when the wind ceases. Winds speeds were then increased to 110mph for 35 seconds, then reduced to zero for one minute to determine recovery.

In the observations, there was neither separation of fence components nor any visible damage. The Trex Seclusions® fence withstood a maximum sustained wind of 110mph, which is equivalent to a “three-second gust” wind speed of 126mph.

In a separate test, the posts were used to see what kind of support the post could withstand. One end of the post was securely anchored to a horizontal test frame. The load was set 38” from the end of the post frame. The post was then loaded with weights until the post failed. The final load the post could withstand was an astonishing 1737lbs.

Trex is a very rigid and durable fence; one that will outlast the tests of time… and wind. You can learn more at www.trexfencing.com or call Fence and Deck Supply at 1-877-700-8739.
