Types of Prefabricated Framing Systems

Prefabricated framing systems are broadly classified into several main categories, including panelized wood framing, steel framing, timber framing, modular systems, concrete systems, and sandwich panels. These systems employ various materials and construction techniques to create components that are pre-assembled in factories and later constructed on-site. Below is a closer examination of each type: 

Panelized Wood Framing

This approach involves manufacturing large, laminated wood panels—typically made with plywood or a roof decking board—in controlled factory settings. These panels are designed for use in walls and roofs, enabling quicker, safer construction processes while minimizing work on-site.

Steel Framing

Steel framing utilizes prefabricated panels made from highly durable metal suitable for both residential and commercial construction projects. Known for its strength and longevity, steel framing is adaptable to many construction needs, particularly in areas prioritizing structural integrity.

Timber Framing

Timber framing relies on pre-assembled timber panels produced in factories for building timber structures. While less commonly used in certain locations, it is considered a preferred choice in regions where timber resources are abundant and easily accessible. 

Modular Systems

Modular construction consists of creating complete building sections, referred to as "modules," within a factory environment. These modules are transported to the construction site for assembly, offering significant levels of prefabrication and streamlining the building process.

Concrete Systems

Concrete systems feature precast concrete panels molded in factories and later assembled on-site. Known for their exceptional durability and versatility in design, precast concrete panels add both strength and aesthetic appeal to various types of buildings.

Sandwich Panels

Sandwich panels are crafted with two facing layers—commonly made of concrete, plywood, or stainless steel—and a core material for insulation. The core is typically composed of foam, paper-based materials, or rubber, providing efficient thermal and structural properties.

Each type of prefabricated framing system has distinct benefits, including reduced construction time, cost savings, and optimal material usage. Builders often consult prefabrication guides to identify the most suitable system tailored to specific project requirements.
