A method of testing the wind resistance of various perimeter metal design was developed by ANSI / Spri. ( American National Standards Institute / Single Ply Roofing Industry ). The testing regimen developed is called ES-1 . Metal edgings, gravel stop, and copings are subjected to a standardized pull test that correlates to the wind uplift forces that the perimeter of a building is subjected to in high wind conditions.


  • ES-1- It is the first roof edge standard developed to aid architects, specifiers, and other roofing professionals in designing and installing a quality metal roof edge system.

  • Our ES-1 system is built weather-tough with premium quality, heavy-gauge materials and a fully supporting anchor chair that will meet the strictest of standards in any size & shape needed.
