Endres Manufacturing Achieves AISC Certification for Arlington Facility While Celebrating 100 Years in Business
Arlington, WI (2026) – Endres Manufacturing Co., a Wisconsin-based structural steel fabricator, is proud to announce that its Arlington, Wisconsin facility has earned American Institute of Steel Construction (AISC) Certification. This achievement marks a significant milestone for the company as it celebrates both the second anniversary of the Arlington location and its 100th year in business.
The Arlington facility, formerly known as Skyline Steel, was acquired by Endres Manufacturing in 2024. Since the acquisition, the company has invested in aligning the facility with Endres’ established quality standards, procedures, and culture. Earning AISC Certification less than two years later reflects the successful integration of the Arlington operation into Endres’ certified quality management system.
“This certification is a reflection of the hard work and commitment of our Arlington team,” said President Sam Ballweg. “Bringing a newly acquired facility into alignment with our long-standing quality standards in such a short time speaks volumes about the people, processes, and culture we have built at Endres.”
Endres Manufacturing first achieved AISC Certification at its original location in 2004, reinforcing their company-wide commitment to quality, consistency, and continuous improvement. For more than two decades, AISC Certification has served as a cornerstone of Endres’ operations, ensuring customers receive structural steel fabricated to the highest industry standards.
AISC Certification is widely regarded as the most respected credential a structural steel fabricator can earn. Certified fabricators undergo comprehensive third-party evaluations to verify their ability to consistently deliver quality products through documented procedures, trained personnel, reliable equipment, and proven quality management systems.
The Arlington certification arrives during a landmark year for Endres Manufacturing, which is celebrating 100 years of service in 2026. Founded in 1926, the company has grown from a local fabricator into a trusted partner on complex structural steel projects across the region, while remaining family-owned and rooted in Wisconsin.
“As we celebrate 100 years in business, achievements like this highlight what has sustained us for a century,” added Sam. “A focus on quality, accountability, and doing right by our customers has never changed.”
With both facilities now AISC Certified, Endres Manufacturing continues to invest in its people, processes, and facilities to meet the evolving needs of its customers and the construction industry. For more information about Endres Manufacturing and its capabilities, visit www.endresmfg.com.
