HEADSTREAM supplies high-strength metal c purlins, steel z purlins, and z & c purlins for steel structure buildings. Made from galvanized steel strips, these purlins provide reliable support for roof and wall systems, with stable load-bearing performance, dimensional accuracy, and corrosion resistance for commercial and industrial construction projects.
Model | Specification (mm) | Thickness (mm) | Strength |
C Shape | C80–400 | 1.5–4.0 | G250–450 |
Z Shape | Z80–400 | 1.5–4.0 | G250–450 |
Special Shape | Custom | 1.5–4.0 | G250–450 |
Material: High-strength galvanized steel strip
Surface Treatment: Hot-dip galvanization
Processing: CNC punching & roll forming
HEADSTREAM metal c purlins and steel z purlins are manufactured from high-quality galvanized steel with strength grades from G250 to G450, providing reliable structural support and long service life for roof and wall systems.
Hot-dip galvanized steel with a coating standard of ≥ Z275 g/m² helps improve corrosion resistance in commercial, industrial, and steel structure building applications.
Advanced CNC punching and roll-forming processes help ensure accurate dimensions, consistent hole positions, and stable installation performance for c section steel purlins and Z-shaped purlins.
Available in both C-section and Z-section profiles, HEADSTREAM z & c purlins can support different structural layouts, including simple-span and continuous-span roof and wall systems.
With over 5,000 tons of regular inventory, HEADSTREAM supports fast production, flexible customization, and reliable delivery for contractors, builders, and steel structure projects.
C section steel purlins are often used where simple connection and stable support are required. Steel z purlins are more suitable for continuous roof systems because their shape allows overlapping connections, helping improve structural efficiency in larger projects.
| Type | Main Feature | Common Use |
| C Purlins | C-shaped section, easy to install and connect | Roof beams, wall girts, simple-span support |
| Z Purlins | Z-shaped section, suitable for lapped connection | Continuous-span roof systems and larger steel buildings |
| C & Z Purlins | Flexible structural support options | Industrial, commercial, and prefabricated steel buildings |
Used in office buildings, shopping centers, hotels, and public facilities to support efficient floor slab construction and reduce on-site formwork work.
Suitable for factories and production facilities that require stable steel floor decking performance, reliable load distribution, and fast installation.
Provides strong support for large floor areas in warehouses, distribution centers, and logistics buildings where construction speed and structural efficiency are important.
Helps form composite floor systems in multi-story steel buildings, supporting concrete slabs while improving construction efficiency.
Can be used for mezzanine platforms in workshops, warehouses, and commercial spaces to create additional usable floor area.
Suitable for prefabricated and modular construction projects where lightweight components, standardized installation, and fast project delivery are required.
