Pre-Engineered Metal Building Frame Systems

Although there are similarities between the many components of different types of metal buildings, the frame systems are often unique. Each pre-engineered frame system is designed to suit a different purpose. Some of the common types of metal building frames include:

RF Systems

RF systems have the steepest roof pitch at 4:12 and have the highest center clearance. These pre-engineered buildings come in widths from 30’ to 120’ and have a wide variety of uses.

LRF and LRFM Systems

Metal buildings with LRF systems can offer excellent clear span space of up to 160’ and, when columns are added, the LRFM system can reach a width of 500’. They have a shallow roof slope of 1:12 and are commonly used in offices, warehouses, and commercial and industrial buildings.

LP2 and LP4 Systems

If a pre-engineered metal building is going to be a shopping center or house palletized storage, an LP2 or LP4 system is ideal. These metal building types can reach up to 500’ in width and provide plenty of clear span floor space by implementing jack beams, bar joists, and straight wall columns. They also offer the lowest roof slopes available.
