The difference between ordinary purlins and heavy purlins
1.5mm to 3.0mm C/Z purlins are different from 2.0mm to 4.0mm C/Z purlins, mainly in terms of their load-bearing capacity, applications, and structural strength. Here's a breakdown of the differences:
Advantages of 1.5mm to 3.0mm C/Z Purlins
1. Lightweight and Easy to Handle
Advantage: These purlins are lightweight, making them easier to transport, lift, and install compared to heavier purlins.
Impact: Reduces labor costs and installation time.
2. Cost-Effective
Advantage: Uses less material compared to thicker purlins (e.g., 2.5mm to 4.0mm), which lowers the overall cost of the project.
Impact: Ideal for budget-friendly construction without compromising on quality for light and medium-duty applications.
3. Adequate Strength for Light-to-Medium Loads
Advantage: Offers sufficient load-bearing capacity for roofing and wall systems in small to medium structures.
Impact: Suitable for residential buildings, small warehouses, and commercial structures.
4. Flexibility in Design
Advantage: Can be easily customized to various lengths, widths, and profiles (C or Z shapes) to suit specific structural needs.
Impact: Ensures compatibility with different construction projects and architectural designs.
5. Pre-Punched Holes for Fast Installation
Advantage: Many manufacturers supply pre-punched purlins, allowing quick and accurate alignment during assembly.
Impact: Minimizes installation errors and reduces time spent on-site.
6. Corrosion Resistance
Advantage: Often made of galvanized steel, which is resistant to rust and corrosion.
Impact: Ensures durability and longevity, even in outdoor environments.
7. Versatile Applications
Advantage: Suitable for various applications, such as:
Roofing supports for light roofs.
Wall girts for cladding systems.
Bracing in pre-engineered buildings (PEBs).
Impact: Makes them a popular choice across multiple industries.
