Purlin Connector

Energet Solar focuses on producing premium Purlin Connector that meets international mechanical standards, widely matched with Z purlins, C purlins and ZAM coated steel purlins in solar power plants, rooftop photovoltaic brackets and factory steel frame construction. As a core fitting between purlins and main support beams, this connector solves loose connection and stress concentration issues that often appear in traditional simple splicing methods.

All Purlin Connector blanks are processed via automatic stamping, bending and precise hole positioning, adopting premium carbon steel raw materials supplied by Xintian Steel. As a long-term bulk buyer of Xintian Steel, we gain stable raw material supply and effective cost control.

Production is carried out in four modern manufacturing facilities covering over 100,000 square meters, equipped with 40+ production lines, including automatic stamping, cold forming, laser cutting and CNC punching systems. With an annual production capacity of 500,000 tons, Energet Solar can efficiently support both standard products and customized structural components for global photovoltaic projects.

Our mature R&D team supplies tailor-made design, special mold opening and non-standard size processing to fit different purlin widths and thicknesses from overseas projects. We deliver one-stop service including structural matching design, batch production, international logistics arrangement and on-site installation technical guidance, lowering customers' accessory procurement workload and speeding up field assembly. Having exported to Europe, Africa, the Middle East and the Americas for years, we are familiar with local photovoltaic construction specifications and steel structure standards to offer targeted matching schemes for global partners.

Product Application

Our Purlin Connector is a standard matching fitting for all types of photovoltaic support systems. In large ground-mounted solar farms, it connects Z and C shaped purlins to form the module laying base, ensuring the entire array frame stays intact under strong wind.

For commercial rooftop solar projects, compact customized connectors fit narrow roof purlin spacing without damaging the building waterproof layer.

In coastal and high-salt areas, anti-corrosion coated versions resist salt fog corrosion for long-term service. Besides photovoltaic scenarios, it also serves as standard connecting hardware for factory roof steel purlins, agricultural greenhouse steel frames and carport support structures.

What Are the Advantages of Our Product?

Compared with common purlin connectors sold in the market, Energet Solar's products have prominent strengths in structural rigidity, compatibility and delivery efficiency.

Our optimized folded clamping structure achieves more uniform force transfer, compatible with most mainstream C/Z purlin specifications used in global photovoltaic projects, with wider matching range than ordinary flat splicing connectors.

We implement strict raw material inspection and finished product load testing, and adopt high-performance anti-rust coating, extending the service life by over 20% versus ordinary stamped connectors.

Supported by independent mold workshop and automatic production lines, we can finish custom mold development quickly, with production lead time 3-5 days shorter than industry average, helping clients shorten project construction cycles and cut on-site assembly labor costs.

Quality Assurance

Every Purlin Connector is manufactured under standardized quality management procedures.
