Cold-Formed Steel C Sections is a cold-formed steel profile produced from hot-rolled steel strip through roll forming. The C-shaped section provides a practical structural profile for steel buildings, roof and wall framing, equipment supports, photovoltaic structures and other steel construction applications.
Rongheng supplies C80–C300 sections with thicknesses from 1.5 mm to 4.0 mm. Standard stock and customized processing are available, including cut-to-length and pre-punched holes.
| PROFILE | C80–C300 | THICKNESS | 1.5–4.0 mm |
| FORMING | Roll forming | SURFACE | Cold formed / Hot-dip galvanized |
| PROCESSING | Cutting / Pre-punching / Hole customization | SUPPLY | Stock and customized production |
The C-shaped cross-section is suited to applications where a standardized, relatively light structural profile is required. Roll forming creates a consistent section along the length, while the available thickness range allows the profile to be specified according to the structural requirements of the project.
For installation work, pre-cutting and hole processing can also be arranged before shipment, helping reduce secondary cutting and drilling at the construction site.

| Consideration | Cold-Formed Steel C Sections | Hot-Dip Galvanized C Section |
|---|---|---|
| Typical Environment | Dry and relatively non-corrosive indoor conditions | Outdoor, humid or corrosion-exposed conditions |
| Surface Treatment | No additional zinc coating | Hot-dip galvanized after cold forming |
| Common Applications | Indoor purlins, equipment supports, ceiling framing and enclosed warehouse structures | PV structures, outdoor factories, curtain wall framing, parking shelters and external greenhouse structures |
| Selection Basis | Consider the structural requirement and indoor environment | Consider structural requirements together with the required corrosion protection |
|
C80–C120 For applications requiring smaller C sections within the available range. |
C140–C180 Intermediate section range for project-specific structural framing. |
C200–C240 Larger section options for applications requiring a different profile size. |
C250–C300 Larger available profiles for specified structural applications. |
Important: The profile size and thickness should be selected according to span, load, connection arrangement and project design requirements. The C80–C300 range should not be treated as a universal structural selection without considering the actual working conditions.
Cut-to-LengthSections can be cut according to specified dimensions before delivery. This is useful when the required installation lengths are already defined by the project. |
Pre-Punched HolesHole processing can be arranged before shipment according to the required installation positions. |
Customized OpeningsFor non-standard hole dimensions or positions, processing details can be confirmed before production. |
|
Steel Building Purlins
Used for roof and wall framing in industrial buildings and factory structures. |
Photovoltaic Structures
Used as C-shaped structural members in photovoltaic mounting and related steel structures. |
|
Equipment Support Frames
Suitable for equipment support structures and steel framing components. |
Curtain Wall Framing
Can be used as supporting members for curtain wall and building envelope structures. |
|
Greenhouse Structures
Used for internal supporting structures or external framing according to the environment. |
Parking Shelters
Galvanized versions can be specified for outdoor shelter structures where additional corrosion protection is required. |
|
Stock Supply Common C Section specifications are available through stock supply for projects requiring regular profiles. |
Customized Production Non-standard processing requirements can be discussed according to profile, thickness, length and hole specifications. |
|
Project Matching Provide span, load and installation information when specification selection needs to be matched with the project conditions. |
Processing & Delivery Cutting and hole processing can be completed before shipment to coordinate with the planned installation process. |
| What sizes of Cold-Formed Steel C Sections are available? | The available profile range is C80–C300, with thicknesses from 1.5 mm to 4.0 mm. |
| Can you cut the sections to a specified length? | Yes. Cut-to-length processing can be arranged according to the required dimensions. |
| Can holes be punched before shipment? | Yes. Pre-punched holes and customized hole positions can be processed according to the confirmed installation requirements. |
| Should I choose cold formed or galvanized material? | The choice depends mainly on the installation environment and corrosion-protection requirements. Cold formed sections can be used in relatively dry indoor conditions, while hot-dip galvanized sections can be considered where additional protection is required. |
| What information is needed for a customized quotation? | Please provide the C section size, thickness, required length, quantity, hole dimensions and positions, surface treatment and other processing requirements. For structural applications, span and load information can also be provided. |
