The Steel Tube Institute of North America (STINA) announced today that six companies who produce steel tubular products have passed its audit process and earned the right to display the coveted STINA Certified Producer mark on their products.
These six companies are the first to have successfully passed the rigorous audits and product testing administered by Intertek, one of the world’s largest providers of auditing, inspections, testing, quality assurance and certification of companies’ products and processes.
All of the facilities certified are producers of steel hollow structural sections, also known as HSS. Two of the companies were able to qualify more than one manufacturing location, Atlas Tube (3) and Bull Moose Tube (2).
The certified facilities are:
• Allied Tube
Morrisville, Pa.
• Atlas Tube
Chicago
Harrow, Ont.
Plymouth, Mich.
• Bull Moose Tube
Trenton, Ga.
Elkhart, Ind.
• Searing Industries
Rancho Cucamonga, Calif.
• Southland Tube
Birmingham, Ala.
• Vest, Inc.
Los Angeles
For the past three months, these six companies have been undergoing a series of internal audits and product testing to assure their processes, manufacturing procedures and products adhere to ASTM and other nationally recognized manufacturing standards.
The Steel Tube Institute’s Producer Certification Program is an ongoing process. Once a company has passed the initial assessment, it is subjected to up to two visits a year by Intertek, who will audit and test the company’s raw materials, production processes and post production test reports, and obtain samples of manufactured tubes for testing at their Verification Center.
Achieving producer certification gives the recipient the right to use STINA’s Producer Certification Mark on, not only its products, but on its website, annual reports, advertising and marketing materials, company letterhead, signage and emails.
