Primary members consist of columns, rafters, beams etc. These are fabricated from high. Strength Gr. 50 HR Plates. Plates are cut to size and shape. Built up sections are made from these plates in Automatic Beam welding Line by submerged Arc Welding.

The most common primary framing systems are shown below. All are shown symmetrical about the ridge line. Framing systems unsymetrical about the ridge line and Multispan Framing Systems with unequal width modules are possible but may require more engineering time and possibly longer deliveries. Practically any frame geometry is possible. Consult a Metal Tech representative for your specific requirements.
