Why Light Gauge Steel Over Wood in Modular
from Built Different · host Spring Street Management Group
Why are modular construction factories switching from wood framing to light gauge steel (LGS)? In this episode of Built Different, we break down the key advantages of steel framing for modular buildings—including dimensional stability, fire ratings, pest resistance, and precision manufacturing. Topics covered: • Light gauge steel vs. wood framing in modular construction • Why steel doesn't warp, shrink, or swell like lumber • How LGS enables Type IIA and IIB construction for taller buildings • Termite and moisture resistance for Gulf Coast, Southeast, and Pacific Northwest markets • Roll-formed steel studs and factory precision manufacturing • Cost trade-offs: 15-30% material premium vs. long-term performance Whether you're a developer, general contractor, or capital partner evaluating modular construction methods, this episode explains why light gauge steel is gaining ground in mid-rise, coastal, and institutional projects. Built Different is a daily podcast about modular, volumetric, and off-site construction. Brought to you by Spring Street Management Group.

What this episode covers
Most modular factories build with wood. But if you're building at scale—especially mid-rise or in markets with fire, moisture, or pest exposure—wood starts to look like the wrong answer.
