Why Steel
Why we build your home in steel.
Every LyteMods home and ADU is framed in light-gauge steel, the same material behind hospitals, hotels, and high-rises, engineered to the AISI S240 standard. Here's what that means for a house you actually live in: it doesn't burn, doesn't warp, doesn't feed termites, and is built to a factory's tolerances instead of the weather's.
The short version
Six reasons steel makes a better home.
Non-combustible
Steel does not ignite, burn, or feed a fire. In a wildfire, the frame is not part of the fuel.
Dimensionally stable
Steel does not shrink, warp, twist, or split. Walls stay straight and square for the life of the home.
Termite- and rot-proof
Steel is inorganic. Termites can't eat it, and it can't rot or grow mold, so there's nothing to treat.
Strong and earthquake-smart
A high strength-to-weight ratio and a lighter structure mean less mass for an earthquake to move.
Healthier walls
An inorganic frame adds no off-gassing fuel and gives mold no food source inside your walls.
Built from recycled steel
Steel is among the most-recycled materials in the world, and the frame is recyclable at end of life.
One honest note: no material makes a building fireproof, and steel isn't magic. It's a stronger, safer starting point, and it's why we pair it with fire-rated assemblies, quality insulation, and factory precision. More on how fire resilience actually works.

From coil to your lot
The steel is made, not just bought.
Your walls begin as steel coil on a roll-forming line, where one 3D model produces the engineering drawings, the panel layouts, and the studs themselves. That's how a LyteMods home reaches millimeter tolerances a job-site frame can't, and why the factory can build while your site work happens in parallel.

Straight answers
What people actually ask about living in a steel home.
Does a steel-framed home feel cold or get cold inside?+
No. How warm a home feels comes from its insulation and windows, not the framing material, and a LyteMods home is insulated to California's Title 24 energy code like any modern home. Steel does conduct heat more readily than wood, a condition called thermal bridging, so steel-framed homes are built with continuous exterior insulation and thermal breaks that stop it. The result is a comfortable, energy-efficient home that heats and cools normally.
Will the steel frame rust over time?+
No, not in normal service. The framing is galvanized, meaning it is coated in zinc that resists corrosion, and it is sealed inside a dry, insulated, weather-tight wall where it never contacts the weather. Steel framing has been used in homes and commercial buildings for decades without the frame rusting. Rust needs sustained water and air contact, which a properly built wall does not provide.
Does steel framing block Wi-Fi or cell signal?+
In practice, no. Wi-Fi and cell signals pass through the drywall, windows, and doorways of a steel-framed home much as they do any other home. Steel-framed offices, hotels, condos, and hospitals run Wi-Fi and phones with no trouble. If a very large home ever has a dead spot, a standard mesh Wi-Fi system or an added access point handles it, the same fix used in any big house, wood or steel.
Can I hang a TV, shelves, and pictures on steel-framed walls?+
Yes. You hang things on a steel-framed wall the same way you would on a wood-framed one, you just use screws made for steel studs. Light items use standard drywall anchors; a mounted TV or heavy shelving goes into the steel stud with self-drilling screws or toggle anchors. A stud finder locates steel studs just like wood ones. Remodeling later works normally too.
Is a steel-framed house noisier, especially in rain?+
No. The sound you hear inside a home comes from the roof and wall assemblies, insulation, and windows, not from the frame being steel. A LyteMods home has a full roof assembly and insulation over the framing, so it is no louder in rain than a wood-framed home, and steel's dimensional stability means no creaking from wood that has shrunk or warped.
Does a steel frame attract lightning?+
No. A steel frame does not attract lightning any more than the wiring, plumbing, and appliances already in every home. If anything, a grounded steel frame provides a safe, continuous path to ground. Lightning protection in any home comes from proper grounding, which is standard in a code-built home.
Is it hard to insure or resell a steel-framed home?+
No. Steel-framed homes are a recognized, code-compliant construction type and are financed, insured, and resold like any other home. In California's fire-prone areas, non-combustible construction is increasingly something insurers and buyers look for, so it can help rather than hurt. We are not your insurer or appraiser, so we do not promise a specific premium or price, but non-combustible steel is a feature more of the market is asking for, not less.
Is cold-formed steel the same as light gauge steel?+
Yes. Light gauge steel (LGS) and cold-formed steel (CFS) are the same material. Cold-formed steel is the formal engineering term used in the AISI framing standards; light gauge steel is the more common construction term. LyteMods frames homes in this material, distinct from the heavy hot-rolled structural steel used for beams and columns.
