Beverly's Story
Beverly's journey in the custom metal fabrication industry began in 1982 when she joined Berry Metal Fabricating, bringing with her a strong belief in craftsmanship, integrity, and long-term relationships. In 1982, Beverly took a bold step forward, acquiring Berry Metal Fabricating with a partner, and Keystone Fabricating Inc. was born.
Over the years, her dedication and vision helped guide the company through steady growth, and by the 1990s, Beverly proudly became the sole owner of Keystone Fabricating Inc.
In 1997, driven by both opportunity and inspiration, Beverly relocated Keystone Fabricating Inc. to historic Bethlehem, Pennsylvania, an area deeply rooted in America's steel-making legacy. Honoring that rich industrial heritage while looking toward the future, she built a brand-new 28,000-square-foot facility designed to support growth, innovation, and efficiency.
This move marked a pivotal chapter for Keystone Fabricating Inc., allowing the company to expand its capabilities and better serve its customers' evolving needs.
Today, Beverly's leadership continues to shape a company grounded in tradition, strengthened by experience, and focused on building lasting partnerships.
