Common c shaped steel channel Models, Load-Bearing Characteristics, and Application Scenarios (Factory/Photovoltaic/Residential)
| Application Scenarios | Recommended Common Specifications (Height H, mm) | Explanation |
|---|---|---|
| Small Factory/Awning Purlins | C80, C100, C120 | Smaller span, lighter load, commonly 1.8mm-2.5mm thickness |
| Standard Industrial Factory Purlins | C140, C160, C180 | The most commonly used range, selected based on span (6-9 meters) and snow load, commonly 2.5mm-3.0mm thickness |
| Large Factory/Warehouse Purlins | C200, C220, C250 | Large spans or heavy loads, thickness typically 3.0mm or more. |
| Lightweight steel structure residential buildings | C80 – C140 | As wall columns and floor beams, thickness is typically between 1.2mm and 2.0mm. |
| Solar photovoltaic brackets | C80, C100 | High corrosion resistance requirements, commonly hot-dip galvanized material, thickness 1.8mm-2.5mm. |
| Mechanical equipment frames, carriages | C100 – C200 | Flexible selection based on equipment weight and structural requirements. |
Main uses of c shaped steel channel
1. C shaped steel channel Construction field (most important application): Steel structure buildings (factories, warehouses, stadiums, etc.):
Roof purlins: This is the most classic application of c shape steel beam. It is installed horizontally between roof trusses to support roof panels (such as color steel plates, sandwich panels).
Wall Beams: Vertically installed between wall columns to support wall panels and enhance wall stability.
Features: Compared to traditional angle steel or channel steel composite components, C-shaped steel as purlins is lighter, stronger, easier to install, and more economical.
Lightweight Steel Structure Housing:
In the “cold-formed thin-walled steel structure” housing system, C-shaped steel is used as the main load-bearing components such as wall frame columns, floor beams, and roof trusses. This structure is lightweight, quick to construct, energy-efficient, and environmentally friendly.
Building Finishing and Auxiliary Structures:
Frames for awnings and carports.
Secondary beams for mezzanine floors.
Linette beams for doors and windows.
The keel support system behind building curtain walls.
2. Manufacturing and Infrastructure
Machinery and Equipment:
Used as frames, bases, and support beams for some light or medium-sized equipment, such as production line supports and conveyor equipment frames.
Vehicle and Shipbuilding:
Used for manufacturing the body frames and floor beams of trucks, trailers, and RVs.
In ships, c shape steel bar is used as the framework for partial compartments or decoration.
Solar photovoltaic support systems:
C-shaped steel is the main material in the support system of solar photovoltaic power plants, used to support and fix solar panels. Its corrosion resistance (usually requiring hot-dip galvanizing) and strength are ideal for long-term outdoor use.
Bridges, guardrails, etc.:
c shape channel is used as an auxiliary component in some temporary bridges or pedestrian overpasses, and is also commonly used as the framework for sound barriers on highways.
