Triangle Bracket Connector

What Is a Triangular Connector for PV Mounting Systems?

Also known as triangular supports or triangular reinforcements, the China Triangle Bracket Connector by Guojian factory are essential structural hardware components for photovoltaic (PV) mounting systems. By leveraging the mechanical stability of the triangle, they connect the main vertical posts, diagonal braces, and horizontal purlins to form a triangular support framework, effectively distributing stresses caused by wind loads, snow loads, and the weight of the PV modules. Standard mounting systems relying on single-point connections are prone to overall swaying, weld cracking, and purlin sagging when exposed to strong winds outdoors over time; installing triangular connectors significantly enhances the rigidity of the entire mounting structure, making them indispensable components for large-scale ground-mounted PV plants, installations on complex mountainous terrain, and projects in coastal areas subject to high wind loads.

Key Product Advantages

✅ One-Stop Factory Supply: Triangular connectors, C/Z/U-shaped steel profiles, PV clamps, and purlin connectors are all manufactured in-house with uniform anti-corrosion treatment. The entire mounting system comes with a unified 25-year warranty, eliminating the need for multi-vendor sourcing and avoiding issues like incompatible specifications or inconsistent anti-corrosion lifespans.

✅ Dual Anti-Corrosion Technologies for All Environments: Hot-dip galvanized coating thickness ≥65μm; Zinc-Aluminum-Magnesium coating features self-healing properties at cut edges and passes 1,000-hour neutral salt spray tests, ensuring long-term durability in coastal saline-alkali areas, fishery-solar hybrid projects, and high-humidity mountainous regions.

✅ Thickened, High-Strength Triangular Structure: Main components are stamped from a single piece of 2.0–3.0mm Q355B steel. The stable triangular mechanical design withstands 60m/s winds and snow loads of 1000N/m², offering high load-bearing capacity without bending or deformation over time.

✅ Reliable Large-Scale Production Capacity: 6,600m² standardized workshop equipped with 20 fully automated CNC punching machines; annual output of 42,000 tons of PV profiles. Standard specifications are kept in stock; bulk orders of 10,000+ units are delivered within 10–15 days, with priority scheduling available for urgent orders.

✅ Certified Quality and Compliance: Holds ISO9001 (Quality), ISO14001 (Environmental), and ISO45001 (Occupational Health) certifications. Each batch includes an original factory quality inspection report, meeting qualification requirements for large-scale PV power plant tenders.

Procurement FAQs

Q: Can the Triangle Bracket Connector be custom-made to fit our specific mounting structure dimensions?

A: We support full customization. We can adjust plate thickness, hole spacing, and aperture angles based on your existing C/Z-section steel mounts; simply provide the mounting drawings, and we can proceed with mold creation and production.

Q: How do I request samples, and can the sample cost be deducted from the bulk order payment?

A: Small quantities of standard-specification samples are provided free of charge; only shipping costs apply. If a bulk project order is placed later, the sample shipping cost can be fully deducted from the order total.

Q: Can this connector be used for coastal "fish-solar" (aquaculture-PV) or saline-alkali soil projects? What is the warranty period?

A: We recommend the Zinc-Aluminum-Magnesium surface finish; the cut edges feature self-healing anti-corrosion properties, making them suitable for highly corrosive coastal areas, fish ponds, and saline-alkali soil environments. Accessories come with a 10-year warranty, and the complete PV system is backed by a 25-year service life guarantee.
