Product Description

Product Description

PREMIUM GALVANIZED C & Z METAL PURLINS

Our galvanized steel purlins deliver an exceptional strength-to-weight ratio and corrosion resistance 
resistance, making them the ideal choice for roofing and wall framing systems in industrial, 
commercial, and agricultural buildings.

Manufactured using precision cold roll forming technology, these structural steel purlins 
feature hot-dip galvanized coating (55-85μm) that withstands harsh coastal and industrial 
environments. Available in C-section purlin (linear spans) and Z-section purlin (continuous 
overlapping) configurations, they adapt seamlessly to various roof slopes and design requirements.

KEY FEATURES & TECHNICAL SPECIFICATIONS

SUPERIOR CORROSION PROTECTION  
Hot-dip galvanized coating (55-85μm thickness) provides multi-layer defense against trust, saltwater corrosion, and industrial chemical exposure-extending service life to 25+ years with zero maintenance requirements

PRECISION-ENGINEERED PROFILES  
Roll-formed from premium Q235/Q355 high-strength steel with uniform thickness (1.5-3.0mm) and strict dimensional tolerances, ensuring consistent structural performance across every component

DUAL CROSS-SECTION DESIGN  
C-type purlins for straight linear spans and Z-type purlins with interlocking capability for continuous runs over 10m-offering maximum design flexibility for complex roof geometries

 purlins processing

C & Z purlin production process has three stages,material preparation and equipment preparation and processing.

Material preparation:The related specs of GI steel strips will be prepared and loaded on equipment;

Equipment preparation:Our workshop manager will check and adjust the equipment to make sure the C & Z  steel purlin equipment is in correct status for production;

Processing:This is including holes pre-punching,cold rolled,cutting as per required length,and stack in proper position and well protected,then finally quality inspection by our QC people.

Product applications:
It is used widely as purlin and wall beam on steel structure construction.Also it can be combined into a light weight roof truss,brackets,etc.In machinery light manufacturing,C purlin can also be made into Column,beam or arm limb,etc.

THERMAL & ACOUSTIC PERFORMANCE

Compatible with insulation materials to achieve U-values ≤0.3 W/m²K, creating energy-efficient building envelopes with enhanced soundproofing properties

CUSTOMIZABLE SPECIFICATIONS

Available in lengths up to 11.85m (custom sizes on request) with multiple thickness options to meet specific load requirements and building codes
