In the building process of any structure, Framing comes after the foundation is poured and has dried. Then the construction crew will create the framework of the building, which consists of, among other things, beams, trusses, walls and partitions, flooring, ceilings, doorways, and window openings. 


01  Light Frame

A system of framing that uses numerous small and closely spaced components assembled by nailing. Barracks and bathhouses are examples of structures requiring only light-frame construction.

02 Heavy Construction

Also referred to as post and beam construction, this method uses large, heavy timbers to build permanent structures.

03 Expedient Framing

Some framing requires more convenient forms of framing techniques. Examples include using salvaged framing and wood substitutes to erect light siding onto structures.

04  Steel Frame

Looking at a framed house, the project may seem somewhat complicated and intimidating. However, the whole process works in a logical order that makes it manageable. There is one intimidating part, however, and that is the framers’ safety.  

Out of 25 different construction sub-industries, the Bureau of Labor Statistics (BLS) reports that framing contractors, identified under NAICS 238130, have the highest percentage of injury incidents: 7.2 for every 100 workers. This statistic should send safety shockwaves through any framer and remind them of the need to wear personal protective equipment (PPE).

This article outlines different construction framing types, occupations that make framed buildings possible, and workers’ safety concerns in this industry. We even provide a quick rundown of essential framing terms, along with a review of the personal protective equipment framers should wear.

Wood is the most often used material used in construction today. Wood framing is the technique defined as the assembly of dimensional lumber that is regularly spaced and fastened together with nails to create the floor, wall, and roof constructions. 

The floor, wall, roof, and stair assemblies are each made up of specific wood components, like a skeleton, which are then fastened together to form the structure. Here is a quick breakdown of the wood measurements used in the different parts:

  • Walls – are usually erected with 2×4 or 2×6 studs and spaced 16 inches or 24 inches apart. 
  • Roofs– are usually built using 2×6 or 2×8 rafters.
  • Floors– are typically constructed with 2×10 joists.

Once the floors and roofs are in place, sheathing is nailed to both before additional material is applied.  


The great strength of steel makes it an excellent material to use in erecting buildings. A building constructed using steel framing is structured very much like those that utilize wood in that they are both built by assembling various components. The most significant difference is that the pieces are made of steel instead of wood. 

Steel framing is most often constructed in a rectangular grid to support the floors, roof, and walls attached to the frame. This technique is how skyscrapers are built. Industrial buildings and warehouses are two other types of structures that are typically framed with steel. Here are some others that utilize a steel frame:

  • Auto shops
  • Aircraft hangers
  • Breweries
  • Car washes

Steel-framed structures may be more expensive than wood frames, but they have many advantages that come with the price tag. For one, steel is durable and provides immense strength to any structure. It’s also ductile, waterproof, and fire-resistant. Instead of cracking like glass, steel will bend its shape, making it an extremely ductile material. While that can’t always be said for the materials attached to it, a structure’s steel skeleton will remain sturdy. Steel also weighs less than wood and takes less time to construct. 

Steel frames can either be cut to correct lengths and then welded together or assembled using prefabricated steel bolted together at the job site. Regardless of which approach is used, the workers who make this all happen are called ironworkers. They are responsible for connecting steel columns, welding metal components, bolting steel frames together, and hoisting girders into place. 

There are roughly 95,000 ironworkers in the U.S. Their work is demanding, and safety concerns are always present. Anyone who works at great heights welding together metal using heat torches must always be on guard against potential hazards.
