American Alloy's History
From a family-owned sheet metal shop founded in Green Bay in 1923 to a fabrication startup launched in Spokane in 2007, two manufacturing legacies came together in 2022 to form a stronger, multi-location organization. Today, American Alloy reflects decades of investment in craftsmanship, manufacturing innovation, and long-term customer partnerships.

American Alloy: Founded on Growth and Customer Partnership
American Alloy was founded in Spokane, Washington in 2007 by Garret and Megan Guinn with a vision to build a manufacturing partner capable of supporting customers through the complex stages between product design and final assembly.
Starting with just a few employees and a small amount of equipment, the company steadily expanded through continuous investment in technology, people, and manufacturing capabilities.
From the beginning, the organization focused on:
- Long-term customer relationships
- Continuous improvement
- Skilled craftsmanship
- Speed, responsiveness, and quality
Over time, American Alloy grew into a full-service metal fabrication and manufacturing organization serving customers across commercial, industrial, and government sectors throughout North America.
The Legacy of Badger Sheet Metal Works
Founded in 1923 by Henry De Caster, Badger Sheet Metal Works became one of Green Bay’s longstanding manufacturing companies and a respected name in Midwest metal fabrication.
Originally focused on furnace and sheet metal supplies for local homes and businesses, the company evolved over decades into a leader in industrial and commercial fabrication.
Under the leadership of three generations of the De Caster family, Henry, Bernarr, and Greg, the company developed a reputation for precision craftsmanship, strong customer relationships, and a culture centered on quality and service.
Many customers throughout Wisconsin and the Midwest still recognize the Green Bay operation by the Badger Sheet Metal Works name today.
Preserving a Century of Craftsmanship
In 2022, Badger Sheet Metal Works became part of American Alloy.
The acquisition was guided by a commitment to preserve the manufacturing culture, customer relationships, and craftsmanship that had defined the Green Bay operation for nearly a century.
Today, the Green Bay facility continues operating as part of American Alloy while carrying forward many of the same values that shaped Badger Sheet Metal Works over generations:
- Quality workmanship
- Responsiveness
- Long-term partnerships
- Pride in manufacturing
The combination of the Spokane and Green Bay operations created a stronger, multi-location organization while maintaining continuity for customers and employees alike.
Continued Investment in Compliance and Manufacturing Standards
In 2025, American Alloy achieved International Traffic in Arms Regulations (ITAR) registration for its Green Bay, Wisconsin facility, with the Spokane facility operating under the same ITAR compliance guidelines.
This milestone reflects the company’s continued investment in secure manufacturing processes, regulatory compliance, and support for customers operating in highly regulated industries.
The ITAR framework strengthens American Alloy’s ability to support defense, aerospace, and other sensitive manufacturing programs requiring strict technical data and security controls.
Built on History. Focused on the Future.
Today, American Alloy continues to build on more than a century of combined manufacturing history across its Spokane and Green Bay operations.
While the company has evolved through growth, investment, and acquisition, its foundation remains rooted in the same principles that shaped both organizations from the beginning: craftsmanship, customer service, continuous improvement, and long-term partnership.
