Beam-Column System

A beam-column is an economical solution for wider buildings spanning 80 inches to over 400 inches with eave heights ranging from 12 inches to 60 inches as it provides multiple spans. It can either be straight, modular, or tapered.

Gable Roof System

This system comes with interior columns or clear span frames which make it an economical solution for wider buildings. It provides a roof with a ridge and two sloping sides. You may opt to add tapered columns to make it a cost-effective solution for various applications such as commercial, industrial, warehouse, and offices.

For display racks and palletized storage, a straight column could be an ideal choice. It can also be used for shopping centers and other commercial building applications. The roof slope can be as steep as 6:12 or as low as ¼:12 while the girts can be placed in either flush or bypass position.

Lean-to System

This system is a preferred option whenever additional space for offices or storage is required. If you want to make your building wider in a cost-efficient way, a lean-to system could be the perfect choice as it utilized a single slope system to either attach to a lower level of the building or extend its roofline.

Single Slope

This system is ideal for retail shopping centers, warehouses, and manufacturing facilities. Its tapered columns are a cheap solution for wider metal buildings while the straights columns enable optimum use of the interior space. Similar to the Gable Roof System, the roof slope can be as steep as 6:12 or as low as ¼:12 while the girts can be placed in either inset or bypass position.


‘Z’ Section – Purlins and Grits

A purlin is a structural component supporting the roof covering while a girt is a horizontal component attached to the end wall or sidewall columns supporting the paneling. Both come in the following primer finish options” dark red, dark gray, and galvanized.

There are three ways by which horizontal girts are attached to the building’s outside columns. They are as follows:

  1. The Bypass Girt – this is the most common condition that has a continuous run around the exterior columns. It provides an air space that is as wide as the grit between the exterior panels and the columns.
  2. Insert Girt – this method minimizes the air space between the outside panels of the building and the columns.
  3. Flush Girt – It offers the maximum amount of floor space even without providing air space between the exterior panels and the columns.

Eave Strut

An eave strut is a structural component supporting the roof and wall paneling and transfers bracing loads to frames. It also comes in various primer options listed above. Depth options for all the three secondary framings are 8’, 9.5’, and 12’.
