The terms “light steel structure” и “heavy steel structure” generally refer to the scale and application of steel in construction.
The differences between light and heavy steel structures are primarily based on the material thickness, load-bearing capacity, and typical applications. These factors determine a project’s cost, construction timeline, and overall durability.
Difference Between Light Steel Structure and Heavy Steel Structure
Light Steel Structure
Light steel structureс typically use thin-gauge steel members, often cold-formed, which means the steel is shaped at room temperature.
Толщина материала: Обычно, the steel sections are thin, ranging from about 1mm to 3mm (0.04 Для 0.12 дюймы).
Manufacturing Process: Cold-formed steel (CFS) is common. This involves bending and shaping thin steel sheets into various profiles (like C-channels, Z-sections, or hat sections) without heating.
Масса: Lighter in weight compared to heavy steel structures, which contributes to easier handling and reduced foundation costs.
Strength-to-Weight Ratio: Offers a high strength-to-weight ratio, making it efficient for certain applications.
Приложения:
Residential Buildings: Often used for framing in single-family homes, multi-story apartments (up to a certain height).
Commercial Buildings: Suitable for low-rise commercial structures, office partitions, interior walls, roof trusses, and flooring systems.
Non-Load Bearing Walls: Excellent for interior partition walls and curtain wall systems.
Modular Construction: Frequently employed in prefabricated and modular building components.
Roof Trusses: Commonly used for creating lightweight roof support systems.
Construction Speed: Faster erection due to prefabrication and lighter components.
Стоимость: Generally more cost-effective for smaller to medium-sized projects.
Fire Resistance: May require additional fire protection measures due to the thinner gauge steel.
Heavy Steel Structure
Heavy steel structures use thicker and heavier hot-rolled steel sections, designed for significant load-bearing capacity.
Толщина материала: Steel sections are much thicker, often ranging from 6mm (0.24 дюймы) upwards, with I-beams, H-Beams, and large plate girders being common.
