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 in household rooftop solar photovoltaic systems, small-to-medium commercial solar projects, flat roof PV installations and ground-mounted solar arrays to securely support and position solar panels.

Fully compatible with conventional photovoltaic brackets, mid clamps, end clamps and matching fasteners, enabling flexible on-site assembly and adapting to various panel installation angles and layouts.

Suitable for mild to moderate outdoor environments including suburban, urban and inland areas, performing stably under daily weather changes and ensuring long-term safe operation of solar power systems.

Applied in distributed photovoltaic renovation projects, portable solar setups and small-scale new energy construction projects, meeting diversified daily PV supporting demands.

Material & Processing Features

Manufactured from high-grade 6063-T5 industrial aluminum alloy, with uniform material density, good plasticity and high tensile strength, balancing light weight and reliable load capacity.

Adopts precision cold extrusion molding technology, ensuring consistent cross-section size, smooth surface without burrs and accurate slot positions, reducing on-site trimming and processing time.

Built with anodized surface treatment, enhancing wear resistance and anti-oxidation performance, preventing surface fading and corrosion, and maintaining aesthetic appearance in long-term outdoor use.

Standardized linear design with even stress distribution, avoiding local stress concentration and prolonging the service life of the entire guide rail assembly.

Core Product Benefits

Lightweight aluminum structure lowers transportation costs and on-site handling intensity, making construction more efficient and labor-saving compared with heavy-duty metal profiles.

Available in fixed standard lengths and customizable length cutting, supporting tailored processing according to project drawings to minimize material loss and save project costs.

Conforms to international PV accessory quality standards, passing routine load testing, hardness testing and salt spray testing, with stable performance and low failure rate.

Easy for later disassembly and reinstallation, supporting system expansion and component replacement, providing a cost-effective and practical supporting solution for long-term solar project operation.
