C Purlin Price
What Is a C Purlin?
C Purlin Price is often influenced by the engineering value these components bring to modern structures. A C Purlin is a type of structural steel member with a cross-section shaped like the letter “C.” It is commonly used in construction as a secondary framing element that supports roof sheets or wall cladding. These purlins are typically made from cold-formed galvanized steel, which provides a high strength-to-weight ratio while maintaining durability and cost-effectiveness.
C Purlins are installed horizontally across rafters or structural frames and are essential for distributing loads from the roof or wall to the main supporting framework. Their standard form factor, combined with the ability to be cut to custom lengths and thicknesses, makes them a popular choice for a variety of steel-framed structures. Whether used in industrial buildings or residential sheds, C Purlins are valued for their efficiency, consistency, and simplicity in installation.
Applications of C Purlins in Construction
C Purlins are widely utilized across multiple construction sectors due to their strength, light weight, and ease of handling—factors that also impact the overall C Purlin Price for each project type. Their main function is to support structural loads in roofing and walling systems, acting as horizontal beams that transfer forces to primary structural members.
Their modular nature, compatibility with pre-punched holes, and the ability to span longer distances with minimal support make C Purlins an economical and practical framing solution in modern construction.
Typical applications of C Purlins
Types of C Purlins Available
The variety of available C Purlins significantly influences both C Purlin Price and structural performance. While standard profiles are widely used in general construction, custom options and alternative profiles like U and Z purlins are essential for specific structural requirements.
Standard C Purlins
Standard C Purlins feature a consistent C-shaped cross-section and are manufactured in pre-defined sizes and thicknesses. These are ideal for typical roofing and wall girt applications in warehouses, workshops, and agricultural buildings. Standard C Purlins often come with pre-punched holes to streamline installation and align with common structural spacings.
These dimensions cover a broad range of structural requirements, from light-duty sheds to large-span industrial buildings. Our standard profiles are designed for high strength, dimensional accuracy, and compatibility with common construction practices.
Custom C Purlins
In addition to standard options, we offer custom-length C Purlins to match your project specifications. Our in-house cutting and punching capabilities allow you to order purlins with precise lengths and hole patterns, reducing on-site work and material waste. Whether you’re working on a small garage or a complex industrial facility, our customization helps save time and ensures a perfect fit.
At our facility, we produce C Purlins using an in-house roll-forming production line capable of manufacturing sections with:
- Web height: 80 to 350 mm
- Flange width: 35 to 80 mm
- Lip height: 10 to 25 mm
C vs U vs Z Purlins: Key Differences
- C Purlins: Provide uniform strength in both directions and are typically used at the ends of structures or as wall girts and intermediate supports.
- U Purlins (Channels): Similar in appearance to C purlins but usually have parallel flanges and are less common in load-bearing applications. They’re often used in lighter structural or framing roles.
- Z Purlins: Feature a Z-shaped profile, allowing overlapping at joints and better continuity across spans. This makes them ideal for roofing applications that require longer uninterrupted coverage and increased structural integrity.
Each profile has its structural advantages, and the right choice depends on load conditions, building design, and installation preferences.
C Purlin Sizes and Specifications
When evaluating C Purlin Price, understanding the available dimensions, and technical specs is essential. These factors directly impact load capacity, installation flexibility, and overall cost.
Common C Purlin Sizes
The variety of available C Purlins significantly influences both C Purlin Price and structural performance. While standard profiles are commonly used in general construction, custom options and alternative profiles like U and Z purlins are essential for specific structural requirements.
C Purlins are manufactured in a variety of standardized sizes to suit different span and load conditions. Some of the most requested sizes include:
- 2×3 inch C Purlin – Popular in light structures like garages and greenhouses
- 150mm C Purlin – Often used in wall and roof support frames in mid-sized industrial buildings
- 200mm C Purlin – Suitable for large-span structures and heavy-duty applications
Available Thickness (Gauge)
C Purlins are typically produced in thicknesses ranging from 0.8 mm to 4.0 mm, depending on the application:
- 0.8–1.6 mm – Light-duty uses (carports, sheds)
- 1.8–2.5 mm – Medium-duty (small commercial buildings)
- 2.5–4.0 mm – Heavy-duty structures (industrial warehouses, solar mounting systems)
Thicker gauges offer greater strength but also increase the unit weight and price.
Weight Per Meter
C Purlin weight per meter is calculated based on size and gauge. For example:
150x50x2.0 mm C Purlin = approx. 6.2 kg/m
200x75x2.5 mm C Purlin = approx. 9.8 kg/m
A 300x75x2.5 mm section can weigh up to 10.5 kg/m
Accurate weight data is essential for estimating transportation costs and structural load design.
Factors Affecting C Purlin Prices
When evaluating C Purlin Price, several key factors come into play—each directly influencing the cost per meter or per ton. Understanding these variables helps buyers make more informed decisions and avoid under- or over-specifying materials for their project.
Larger C Purlins (e.g., 300–350 mm web height) require more raw material and result in higher weight per meter, directly increasing the price. Smaller profiles like 100x50 or 150x60 are more economical and suitable for lighter applications.
Steel thickness is one of the most significant cost drivers. A 2.5 mm thick C Purlin will weigh—and cost—considerably more than a 1.5 mm option. Thicker sections are used for heavy loads or longer spans and will also influence fabrication and transportation costs.
Protective coatings can add to the unit cost but may reduce long-term maintenance expenses. Zinc-flake coatings or hot-dip galvanizing offer greater protection but come at a premium.
Options like custom lengths, pre-punched holes, or precision cuts increase labor and setup time, which may reflect in the price. However, they often lower site installation costs and material waste.
Local steel prices, transportation costs, and supplier proximity all affect the final C Purlin Price. For remote projects, shipping heavier profiles can add a noticeable premium.
How to Choose the Right C Purlin for Your Project
Selecting the correct C Purlin is critical to the structural integrity, cost-efficiency, and durability of your build. Consider the following factors when making your decision:
Load-Bearing Requirements
Different buildings have different structural loads. Choose a web height and gauge that matches the expected dead load (roofing, insulation) and live load (snow, wind, equipment). For heavy-duty projects like warehouses, use higher web heights (250–350 mm) and thicker gauges (2.5 mm and above).
Span Capacity
Longer spans between supports require stronger and deeper purlins. For example, a 200x70x2.5 mm C Purlin may span 4–5 meters, while larger sizes can reach up to 6–8 meters with proper design. Z Purlins may also be better for very long spans due to their lapped joint capabilities.
Surface Coating
Use galvanized or zinc-flake coated C Purlins for general outdoor applications, where humidity or rain may be a factor. It is strongly suggested to opt zinc-flake coatings for aggressive environments—such as coastal zones or chemical plants—where corrosion resistance is a top priority.
Design & Compatibility
Ensure the selected profile:
· Matches your frame design and cladding system
· Includes pre-punched holes or custom lengths where necessary to reduce labor
· Complies with local building codes and structural standards
Consulting with a structural engineer or supplier can help you avoid over-specifying or using incompatible materials, saving time and budget. Our sales experts are willing to give you consultation services regarding finding the right C purlin matches the need of your project.
