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

Commonly used for installing photovoltaic systems on trapezoidal metal roofs, such as industrial factory roofs, warehouse roofs, commercial building roofs, and residential metal roofing projects.

Compatible with a variety of standard trapezoidal metal roof panels, enabling non-destructive fixing of PV guide rails and preventing roof leaks caused by drilling.

Works with 3040 aluminum guide rails, mid clamps, side clamps, and other photovoltaic accessories to form a complete metal roof solar mounting system.

Suitable for distributed PV projects, rooftop solar power stations, and commercial PV retrofits, adapting to different trapezoidal roof specifications and installation angles.

Material & Processing Features

Manufactured from high-quality 6063-T5 aluminum alloy, which is lightweight yet strong, offering excellent oxidation resistance, corrosion resistance, and weather resistance for prolonged outdoor use.

Produced through precision stamping and CNC bending processes, ensuring accurate trapezoidal curvature and a tight fit with roof panels, preventing slipping or loosening under wind loads.

Features an integrated anti-slip rubber pad that absorbs vibration, protects the roof panel surface from scratches, and enhances the stability of the clamping connection.

The anodized surface treatment improves wear resistance and salt spray resistance, making it suitable for coastal, high-humidity, and industrial polluted environments.

Adjustable clamping structure with reserved mounting holes, flexible adaptation to different thicknesses of trapezoidal roof panels.

Core Product Benefits

Tool-free quick installation design, no need for drilling or welding, shortens construction period and reduces roof damage risk.

Trapezoidal adaptive design ensures full fitting with roof contours, improving wind pressure resistance and overall system stability.

Strong universality and wide application range, compatible with most trapezoidal metal roof types on the market.

High load-bearing performance, effectively withstands extreme weather such as strong winds and heavy snow, ensuring system safety.

Comply with international metal roof PV installation standards, pass salt spray test and tensile test, stable quality and long service life.

Detachable and reusable design, convenient for later system maintenance and expansion, cost-effective for metal roof solar projects.
