What products does Youlong manufacture?

Youlong manufactures photovoltaic mounting components such as aluminum guide rails, water channels, angle brackets and connectors, plus precision fasteners including anchor bolts, carriage bolts, expansion bolts, flat washers and wing nuts for solar, wind power and construction projects.

Can you produce custom PV brackets and fasteners to my drawings?

Yes. Our automated stamping, forging and CNC machining lines support OEM and custom production. Send drawings or samples with material, finish and quantity requirements, and our engineers will confirm feasibility, tolerances and a written proposal.

How do you control the quality of fasteners for outdoor solar projects?

We run random inspections from raw material intake to final dispatch and test against industry standards, including salt spray corrosion testing and tensile strength testing, so that hardware performs reliably in long-term outdoor exposure.

Which material should I choose for coastal or high-humidity PV sites?

For coastal, offshore or industrial sites with high corrosion categories, stainless steel grade 316 (A4) fasteners are generally recommended. For inland sites, 304 (A2) stainless or hot-dip galvanized carbon steel is commonly specified. Isolating washers help prevent galvanic corrosion between aluminum rails and steel hardware.

Where is Youlong located and do you export worldwide?

Youlong is located in Yongnian District, Handan City, Hebei Province, known as China's Fastener Capital. We have served more than 100 clients worldwide with cumulative shipments exceeding 300,000 tonnes.

Product Description

Product Application

Widely used for pressing and fixing guide rails, brackets and connecting components in ground PV power stations, metal rooftop solar systems and distributed photovoltaic installations.

Suitable for 3040 aluminum guide rails and conventional photovoltaic mounting profiles, realizing stable compression and preventing horizontal displacement of mounting parts.

Compatible with photovoltaic bases, angle brackets, purlin connectors and standard fasteners, forming a complete and firm solar panel supporting structure.

Applied in industrial, commercial and residential solar projects, adapting to flat roofs, sloped roofs, open ground and other common photovoltaic installation scenarios.

Material & Processing Features

Made of high-grade 6063-T5 aluminum alloy, with lightweight property, high compressive strength and good toughness, reducing the overall load of PV mounting systems.

Adopts precision stamping and integrated bending process, with accurate double-hole spacing, smooth surface and burr-free edges, ensuring tight fitting and safe assembly.

Reinforced pressing surface design distributes stress evenly, avoiding local deformation of guide rails and components under long-term compression and wind vibration.

Equipped with standard oblong mounting holes, allowing fine-tuning of installation position to adapt to different profile sizes and construction needs.

Anodized surface treatment forms a dense protective layer, with excellent anti-oxidation, anti-rust and salt spray resistance, suitable for long-term outdoor harsh environments.

Core Product Benefits

Double-hole fixed design enhances pressing stability, effectively disperses external force and prevents loosening of photovoltaic mounting components.

Simple and compact structure enables quick on-site installation, simplifying construction steps and improving the overall efficiency of photovoltaic projects.

Strong versatility and compatibility, matching various aluminum profiles and PV accessories, supporting customized size processing per project drawings.

Excellent weather resistance and anti-aging performance, suitable for coastal, high-humidity and high-cold areas, prolonging the service life of the whole mounting system.

Comply with international photovoltaic accessory quality standards, passing tensile tests, salt spray tests and load tests, with stable performance and reliable quality.

Detachable and reusable design facilitates later system maintenance, adjustment and expansion, providing a cost-effective pressing solution for solar projects.
