ULTRASEAM

METAL ROOFING & SIDING SYSTEMS

When aesthetic requirements call for a curved roof, the Ultra Seam US-150C Curved Panel is the system of choice. The mechanically seamed panels can be curved to a 19” inch radius in aluminum and a 36" radius in steel and copper. Call for more information.

The Ultra Seam standing seam system utilizes state of the art technology for roof integrity and positive weather-tightness. The Ultra Seam US-150 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 ASTM 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 long and/or low, and unusually long panels are required. Non-skinning butyl in-seam sealant available. Available in various gauges of galvanized steel, galvalume, zincalume, aluminum, copper, zinc and stainless steel. Regardless of which material is selected, the optional stiffening ribs or striations are highly recommended in order to reduce the slight surface waviness of the metal known as “oil-canning.” Note: “oil-canning” is a natural phenomenon inherent in sheet metal products and therefore is not cause for rejection of the material.
