C-Purlin Steel

 

 

With their robust design, high durability, and excellent load-bearing capacity, C-purlins (also known as C-section steel) have become an essential material in modern construction, particularly in pre-engineered steel buildings. Among the various types, galvanized C-purlins are the most widely used due to their superior corrosion resistance and longevity. However, to ensure both quality and affordability, customers should choose reputable suppliers. Below, we explore the features, technical specifications, and reliable sources for galvanized C-purlins in Hanoi.

 

 

C-purlins are a type of structural steel with a C-shaped cross-section, featuring two perpendicular flanges of equal size. These purlins belong to the steel profile category and are widely used in construction due to their:

 

- Fire resistance
- Anti-rust & anti-corrosion properties
- Termite resistance
- Lightweight yet durable structure
- Stable quality (no warping, bending, or twisting)

 

 

 

- Support the weight of roofs, floors, and cladding materials.

- Reinforced by rafters, steel beams, or masonry walls.

 

 

Our galvanized C-purlins are manufactured using advanced production lines, adhering to Vietnamese, American, Japanese, Chinese, and EU standards. The multi-stage production process ensures:

 

- High load-bearing capacity
- Durability in harsh conditions
- Ideal for industrial steel structures, prefabricated buildings, and railway projects

 

 

 

- Yield Strength: ≥ 245 MPa

- Tensile Strength: ≥ 400 MPa

- Elongation: 10 – 30%

- Zinc Coating Weight: 80 – 275 g/m² (both sides)

 

 

 

- Made from galvanized steel coils or black steel strips.

- Coated with electrolytic zinc, cold galvanizing, or hot-dip galvanizing for enhanced rust resistance.

- Formed into C-shape using precision molds and cut to customer specifications.

 

 

- Made from black steel coils without galvanization.

- Prone to rust and oxidation, leading to a shorter lifespan.

- Lower cost compared to galvanized purlins.
