Light Gauge Steel Framing: Benefits, Costs, and Process
At Ningbo DeepBlue Smarthouse Co., Ltd., we understand that considering a new building method like Prefabricated Light Steel Frame (LSF) construction brings many questions. We've compiled this comprehensive FAQ to provide clarity and confidence as you explore the future of building.
Part 1: Understanding the Basics
Q1: What exactly is a Prefabricated Light Steel Frame (LSF) home? A: A Prefabricated LSF home is a modern building system where the structural frame is made from high-strength, cold-formed galvanized steel. Unlike traditional construction, the components are precision-engineered and manufactured off-site in our controlled factory. These components are then shipped to your site and assembled efficiently, like a high-precision kit, to form the complete structure of your home.
Q2: Is this the same as a "shipping container house" or a "modular box"? A: No, not at all. While both are forms of off-site construction, LSF offers complete design freedom. Our system uses a skeletal frame, which can be clad with virtually any exterior and interior finish you choose—brick, render, timber, composite panels—allowing it to perfectly mimic the appearance of a traditional home or achieve any modern architectural style.
Part 2: Durability, Safety, and Performance
Q3: How durable is a steel frame compared to wood or concrete? A: Extremely durable. Our galvanized steel frames are impervious to the most common problems of wood: they will not rot, warp, shrink, or attract termites, mold, or pests. Steel also has a higher strength-to-weight ratio than wood, making it exceptionally robust and long-lasting.
Q4: Are these homes safe in earthquakes, hurricanes, or fires?
A: Yes, this is one of their key advantages.
Earthquakes: Steel is flexible and has high ductility, allowing it to absorb and dissipate seismic energy without catastrophic failure, making it an excellent choice for seismic zones.
High Winds: Our frames are structurally engineered to meet strict wind load codes (e.g., for hurricane-prone areas).
Fire: Steel is a non-combustible material. It will not fuel a fire, providing a critical safety barrier and potentially lower insurance premiums.
Q5: Aren't steel houses cold in winter and hot in summer?
A: This is a common misconception. In fact, LSF homes are incredibly energy-efficient. The precise frame allows for continuous, full-batt insulation without gaps or compression. More importantly, it minimizes "thermal bridging" (a key source of heat loss in traditional frames). When combined with high-performance insulation, the result is a highly stable indoor temperature, significantly reducing your heating and cooling costs.
