The H.M. King High School in Kingsville, Texas was designed to provide an environment fostering student success. To accomplish this, technology was bundled to offer state-of-the-art engineering and science labs; and a packaged exterior roofing system incorporating a mechanically seamed, workhorse roofing panel, PowerSeam, and hand-crafted cupolas by CopperCraft was installed in three phases, safeguarding years of learning.
