Transit Infrastructure - Manufacturing Solutions in Anaheim, Orange County, Los Angeles, Irvine, Santa Ana, Fullerton, and Southern California

In 2022, Pen Manufacturing acquired American Sheet Metal in Anaheim to better serve California’s infrastructure sector. American Sheet Metal has contributed to the construction of most metro stations across Los Angeles, Orange County, and other regions in the state. Their work includes bridge drainage systems, seismic reinforcements, architectural metals, metal roofing and paneling, artistic elements, and other structural components.  Today, Pen is a premier vendor for major infrastructure general contractors in California. With in-house civil engineers, the team supports customers with drawings, design-for-manufacturing, shop approval documents, and project coordination.  American Sheet Metal—Pen’s sister brand—is active across major construction platforms like BuildingConnected, BidMail, and The Blue Book, making it a trusted partner throughout the transit and broader construction supply chain.
