When planning a new construction project — whether it’s a house, ADU, or commercial building — one of the first decisions you’ll face is the choice of framing material: Light Gauge Steel (LGS) or traditional wood framing.
Both systems have their strengths and weaknesses. In this article, we’ll break down the key differences between LGS and wood framing so you can make an informed decision based on cost, durability, speed, and long-term value.
Basic Overview
Wood framing has been the dominant method for residential construction in the U.S. for over a century. It’s accessible, familiar, and widely supported by the labor market.
LGS (Light Gauge Steel) is a modern alternative that uses cold-formed, galvanized steel profiles. It’s popular in Europe, Asia, and increasingly in California due to its precision and fire resistance.
Comparison Table: LGS vs Wood Framing
| Feature | LGS Framing | Wood Framing |
|---|---|---|
| Fire Resistance | ✓ Non-combustible | ✗ Flammable |
| Pest Resistance | ✓ Immune to termites, mold | ✗ Susceptible to rot and insects |
| Environmental Impact | ✓ Recyclable, no deforestation | ✗ Depends on tree harvesting |
| Weight | ✓ Lightweight | ✓ Lightweight |
| Installation Speed | ✓ Fast with prefab kits | ✓ Fast with standard crews |
| Labor Availability | ✗ Requires trained teams | ✓ Widely available carpenters |
| Cost (Initial) | ✗ Typically higher | ✓ Lower upfront |
| Long-Term Durability | ✓ Excellent (doesn’t warp) | ✗ Can degrade over time |
When to Choose LGS Framing
- You’re building in a fire-prone or humid area (e.g. California hillsides or coastal zones)
- You want precision and minimal on-site waste
- You plan to use prefabricated components to speed up construction
- You need higher structural integrity for multi-story or modular builds
When Wood Framing Still Makes Sense
- You’re working with a tight budget and standard residential layout
- You have access to a skilled local crew familiar with wood framing
- You’re building in a dry climate with low fire and pest risk
- You prefer natural materials and traditional methods
