Triangular Connector

The Triangular Connector is a structural reinforcement component used to connect beams, columns, and support members within photovoltaic mounting systems. Its triangular geometry creates a naturally stable load-bearing structure that distributes forces more evenly than conventional flat connectors, helping improve the overall rigidity of the support frame.

Whether installed in rooftop systems or large ground-mounted solar farms, the connector enhances the structural integrity of mounting systems exposed to wind, snow, and long-term environmental stress.

Premium Materials for Long-Term Durability

Every Triangular Connector is manufactured using Q355B (S355JR) high-strength carbon steel, providing excellent tensile strength and structural toughness. To withstand harsh outdoor conditions, each component is protected with a 45--85 μm hot-dip galvanized coating, offering outstanding resistance to corrosion, moisture, UV exposure, and salt spray.

This combination of high-strength steel and industrial-grade corrosion protection helps ensure reliable performance throughout the service life of the solar installation.

Precision Manufacturing for Easy Installation

Our production process combines automatic stamping, CNC punching, precision bending, and strict dimensional inspection to ensure consistent product quality.

Accurate hole positioning and tight manufacturing tolerances enable fast installation while reducing alignment issues during assembly. Smooth edges and uniform surface treatment further improve installation efficiency and component reliability.

Flexible Customization for Different Projects

Different photovoltaic projects require different structural configurations. Energet Solar provides comprehensive customization services, including:

- Connector dimensions

Precision CNC processing ensures accurate hole positioning, consistent bending angles, and excellent dimensional consistency, reducing installation time and improving assembly quality.

Strong Compatibility

Compatible with a wide range of photovoltaic mounting systems and structural components, allowing easy integration into both new installations and retrofit projects.

OEM & ODM Support

Energet Solar offers customized production according to customer drawings, technical specifications, or project requirements, supporting both standard and non-standard applications.

Installation Guidelines

Select the Correct Connector

Choose the appropriate thickness and dimensions based on structural design, wind load, and mounting system specifications to achieve optimal reinforcement.

Prepare the Connection Surface

Ensure all contact surfaces are clean, flat, and free from rust, oil, or debris before installation to achieve full structural contact.

Apply Proper Bolt Torque

Tighten bolts according to the recommended torque values. Excessive tightening may deform the connector, while insufficient torque may reduce connection stability.

Avoid On-Site Modification

Do not cut, weld, drill, or bend the connector after installation, as structural modification may reduce its designed load-bearing capacity.

Perform Routine Inspection

For coastal or high-humidity environments, periodically inspect the galvanized surface and fasteners to maintain long-term corrosion protection.

Common Installation Mistakes

Several installation mistakes can reduce the structural performance of a solar mounting system.

Incorrect Bolt Torque

Over-tightening may deform the connector, while insufficient torque can cause joint movement during operation.

Misaligned Installation

Improper alignment creates uneven stress distribution and increases structural fatigue over time.

Mixed Fastener Grades

Using bolts with different strength grades may result in inconsistent load transfer and reduced connection reliability.

Damaged Galvanized Surface

Scratches or excessive cutting after galvanizing may expose the steel substrate and accelerate corrosion.

Why Our Triangular Connector Performs Better

Higher Structural Stability

The optimized triangular geometry provides more efficient force transmission than traditional flat connectors, helping reduce vibration, joint loosening, and structural deformation during long-term operation.

Longer Outdoor Service Life

Hot-dip galvanizing offers superior corrosion resistance compared with painted or electro-galvanized products, reducing maintenance requirements throughout the project lifecycle.

Better Assembly Precision

Consistent manufacturing tolerances improve installation efficiency and reduce alignment errors during field construction.

Engineering Customization

Unlike many standard connectors on the market, our products can be customized to meet unique structural layouts, mounting systems, and project-specific engineering requirements.
