The newly issued evaluation by QAI Laboratories, a leading provider of testing and inspection services, officially validates the structural integrity, performance, and code compliance of the MHS Modular Aluminum Framing System—a prefabricated post-and-beam technology designed for faster, stronger, and more sustainable building solutions.
“This milestone reinforces our commitment to innovation and regulatory excellence,” said Tim Siahatgar, inventor of the MHS system. “With QAI’s evaluation, we’re positioned to expand our modular building systems into more regions, offering builders and developers a certified, high-performance alternative to conventional wood and steel framing.”
Key Highlights of the MHS Evaluation Report:
• Approved for multi-story construction projects
• Certified for use in high seismic and wind load zones
• Compatible with SIP panel assemblies, conventional infill systems, and various architectural finishes
• Constructed from lightweight, corrosion-resistant aluminum extrusions
• Features interlocking bolted connections for rapid, on-site assembly
• Fully recyclable and ideal for sustainable, code-compliant modular construction
The QAI evaluation provides engineers, code officials, and design professionals with a reliable third-party reference to specify MHS framing components in structural applications across the U.S. and international markets.
