Standard Framing System

The most common primary systems are shown below. All shown are symmetrical about the ridge line. Framing systems about the ridge line and multi-span framing systems with unequal width modules are also possible, as symmetrical. In fact, practically any frame geometry is possible; a PEB Steel representative will be happy to discuss any specific requirements and recommend optional solutions.
