Service Overview
We manufacture premium-grade, cold-formed C and Z purlins alongside rectangular and circular downspout pipes. Our purlins are custom-fabricated from high-tensile galvanized steel to support heavy roof and wall loads. Z-purlins are designed with unequal flanges, allowing them to overlap seamlessly for continuous structural beams, which increases overall frame rigidity and load capacity.
Key Advantages
Overlapping Z-purlin designs for continuous beam strength
High-tensile steel coils providing maximum bending resistance
Accurate pre-punched hole patterns on CNC lines for fast assembly
Heavy-duty galvanized finishes protecting parts from moisture
Custom downspouts and gutters designed for rapid rainwater drainage

Frequently Asked Questions
What is the benefit of overlapping Z-purlins?▼
Overlapping Z-purlins creates a continuous support system over columns, doubling the steel thickness at high-stress points. This allows for lighter sections to span longer distances, saving steel weight.
Are your purlins pre-punched for fast installation?▼
Yes, our purlins are pre-punched to exact spacing on automated roll-forming lines, so they can be bolted directly to cleats without any on-site drilling.
