Clad Entry Door Frames
Our clad entry door frames combine treated wood substrates with 16-gauge extruded aluminum for superior durability. Designed for pre-hang facilities, these systems resist moisture, rot, and warping while maintaining aesthetic flexibility. Available in multiple finishes and depths, they ensure seamless integration with various architectural styles.
Composite Door Frames
Engineered composite door frames offer exceptional resistance to mold, insects, and environmental damage. Featuring a closed-cell structure and 20-minute fire rating, these frames maintain structural integrity without requiring aluminum support channels. Customizable with paint or stain for both interior and exterior applications.

We manufacture wood and aluminum window grilles in diverse profiles for residential and commercial use. Our SDL bars feature minimal expansion/contraction and offer stainable vinyl-wrapped finishes that match fiberglass doors.
