DOUBLE LOCK
The Ultra Seam standing seam system utilizes state of the art technology for roof integrity and positive weather-tightness. The Ultra Seam panel has been extensively tested in both steel and aluminum and meets the stringent requirements of the "Standard Test Method for Structural Performance of SSMRS by Uniform Static Air Pressure Difference, "which has been adopted as ASTME E-1592. Seams require machine closing, by either hand or power seamers, both available on a job rental basis. The seaming process completely encloses and seals all clips and fasteners for the most watertight seal available. The US-150 panel, in addition to the standard 90-degree seam, can be double-locked to obtain a 180-degree architectural profile. The standing seam system is especially suitable where roof slopes are low and unusually long panels are required. Available in various gauges of galvanized steel, galvvalume, aluminum, copper, and stainless steel. Regardless of which material is selected, the optional stiffeningribs or striations are highly recommended in order to reduce the slight surface waviness of the metal know as "oil-canning." Note: "Oil-canning is a natural phenomenon inherent in sheet metal products and therefore is not the cause for rejection of the material.
