AI Overview
Hot-dip galvanized C purlins are cold-formed, corrosion-resistant structural members used as roof and wall supports in steel construction. Offering high strength, durability, and a lightweight, economical design, they are made of carbon steel coated with zinc (often 120-275g/㎡) to prevent rust. Key for spanning metal buildings, they provide reliable structural integrity, with common uses including warehouses and factory framing.
Key Features and Advantages
- Superior Corrosion Resistance: The hot-dip process, complying with standards like ISO 1461, creates a durable zinc-iron alloy coating that protects against rust, even in high-humidity or corrosive environments.
- High Strength-to-Weight Ratio: Despite being lightweight—reducing overall structure weight—the Cold-formed C section is engineered for high compressive strength.
- Customization: C purlins can be tailored in size and thickness to meet specific project needs, typically featuring uniform zinc coating, smooth surfaces, and high dimensional accuracy.
- Easy Installation: These purlins are pre-fabricated for quick, bolted assembly on site, saving on labor and time.
Applications in Steel Structure
- Roof and Wall Framing: They act as horizontal members that hold up siding and roofing sheets, transferring loads to the main structural frame.
- Small to Mid-Scale Buildings: Ideal for simple structures with small bay spacing, single spans, and industrial sheds.
- Industrial/Commercial Usage: Widely used in factories, supermarkets, and warehouse construction.
