Special Moment Frames

The Hardy Portal Frame is a pre-fabricated, pre-engineered system that utilizes the new-generation SidePlate® special moment connection technology.


The First Pre-Engineered, Pre-Fabricated Moment Frame

The Hardy Portal Frame has been approved by the American Institute of Steel Construction (AISC) – the national standard for prequalified special / intermediate steel moment frame connections in seismic applications.

Design Your Custom Frame

Design Professionals and Engineers of Record can use our Special Moment Frame Design Manager to enter project, design, geometry and loading information which is automatically transmitted to MTek. The data is used by MiTek engineers to design the frame.

State of the Art, Lateral Force Resisting Systems

The Hardy Portal Frame is a state-of-the-art, pre-fabricated, pre-engineered system that utilizes the new-generation SidePlate® moment connection technology to resist lateral forces from high wind and earthquake loads

This breakthrough system allows buildings to be designed with larger openings and less wall area while exceeding the most stringent building code requirements for moment frame construction.

In January 2006, Hardy Frames, Inc., manufacturer of the Hardy Frame® Panel and Hardy Frame® Brace Frame, joined forces with SidePlate Systems, Inc. to develop a standardized Moment Frame for the residential and light commercial industry.

The SidePlate system is nationally recognized and is the first code-approved moment connection to be pre-qualified by ICBO-ES, ICC-ES, and LA City. This connection now has a history of extensive use in hospitals, government buildings and other heavy steel frame applications.
