These aluminum alloy products for foreign trade—including clamps, mid-clamps, and end-clamps—are essential structural connectors used in the installation of photovoltaic (PV) modules. Manufactured from 6005-T5 or 6063-T5 aluminum alloy via extrusion, they undergo precision machining and an anodized surface treatment. The components feature an integrated anti-slip serrated design and are paired with EPDM rubber pads; once tightened, they increase friction to prevent PV modules from shifting under high winds or heavy snow loads, while also cushioning the clamping force to protect the module’s aluminum frame and glass from damage.
These aluminum clamps secure PV systems to metal roofing (such as standing-seam or corrugated steel sheets) through mechanical clamping. This eliminates the need for drilling holes, preserving the integrity of the roof’s waterproof layer and preventing leaks at the source—making them ideal for existing roofs or facilities with insulation layers where drilling is not feasible.
Extruded from 6005/6063-T5 aluminum alloy and finished with an anti-corrosive anodized coating, these components are lightweight and impose minimal additional load on the roof. They offer long-term stability even in coastal areas (exposed to salt spray) or regions with high UV radiation. With a design lifespan of 25 years or more, they help reduce the labor and operational downtime costs associated with future component replacement.
The aluminum alloy products for foreign trade including clamps, pressure blocks, L-brackets, and adapters—is compatible with most mainstream metal roofing profiles and standard PV module frames. We offer custom mold development based on specific roof profiles and module thicknesses, ensuring a single, cohesive clamping system can be adapted to various project sites and eliminating the need for on-site modifications.
Clamps, fixtures, L-brackets, hooks, and fasteners are supplied by the same manufacturer as the aluminum alloy rails and steel mounting structures. This ensures a high degree of compatibility between the components and the profiles, preventing issues such as poor fit or loose connections during on-site assembly. Sourcing everything from one supplier reduces the need to coordinate with multiple vendors and simplifies customs clearance and logistics.
Aluminum alloy products for foreign trade are sorted and packed individually by model and specification. Each item is wrapped in protective film or bagged to prevent collisions or scratches to the anodized surfaces.
Each box features a clear external label indicating the model, quantity, and batch number. A packing list is included, allowing for quick inventory checks and organized sorting upon arrival at the site.
Goods are packed in reinforced cartons or wooden crates, complete with corner protectors and cushioning materials. Smaller clamping accessories can be palletized and strapped to prevent damage or deformation during sea or land transport.
Before shipment, all items are counted and specifications are verified to ensure that the actual goods match the packing list and customs documentation, eliminating the risk of shortages or missed items.
We support split-shipment deliveries. Export orders include Material Test Certificates (MTC), packing lists, and customs documentation. We offer professional container-loading solutions, with FOB terms available via Tianjin Port.
We provide assistance with component selection, installation planning, and load-bearing consultation. Remote guidance is available for clamping torque specifications and compatibility with various panel types. In the event of transit damage, we offer rapid replacement upon receipt of photographic evidence.
This series of aluminum alloy products for foreign trade—including mid-clamps, end-clamps, and standing-seam roof clamps—serves as a fastening solution for PV modules. These components are highly compatible with a wide range of distributed and utility-scale PV projects, both domestically and internationally, and can be integrated with PV rails to form a complete mounting and fixation system.
This is the most prevalent application. For color-steel roofs (such as standing-seam or "Jiao-chi" types) found on factories, production workshops, and logistics warehouses, specialized clamps are used to secure the system by gripping the roof ribs—eliminating the need for drilling. PV modules are then fastened using mid-clamps and end-clamps. This method preserves the integrity of the existing waterproof layer, prevents leaks caused by drilling, and offers high installation efficiency, making it ideal for both large-scale distributed PV retrofits and new construction projects.
For ground-based projects—whether in mountainous regions, plains, or tidal flats—mounting rails combined with mid-clamps and end-clamps are typically used to secure PV modules. These components offer stable mechanical performance, capable of withstanding external loads such as strong winds and heavy snow. They are well-suited for large-scale, standardized on-site installation and facilitate future maintenance or replacement of the modules.
Older industrial buildings often feature aged color-steel roofing that is unsuitable for drilling. Specialized aluminum alloy mounting components utilize mechanical clamping to secure the system without requiring any roof penetrations. This approach maximizes the protection of the existing roof structure, minimizes the risk of leaks during retrofitting, and is perfectly suited for adding PV systems to existing industrial facilities.
In coastal areas or on islands—characterized by high humidity and high salt-mist levels—anodized aluminum alloy components are used. These materials offer excellent corrosion and salt-mist resistance, ensuring they do not easily rust or degrade. They prevent rust-related contamination of the color-steel roofing or PV module frames, meeting the 25-year operational lifespan requirements for industrial and commercial rooftop or tidal-flat PV projects.
For PV carports and roofs associated with energy storage facilities, a combination of specialized clamps and fasteners is used to secure the PV panels. This method ensures the waterproof structure of the carport remains intact and that the load is distributed evenly. It effectively balances power generation with the functional requirements of the structure itself, serving as a standard mounting solution for energy storage-integrated PV systems and solar-powered carports.
Our aluminum alloy products for foreign trade are designed to be compatible with a wide range of mainstream international colored steel roof profiles and PV module specifications. We provide essential documentation—including material test certificates (MTC), salt spray test reports, and CE-related compliance papers—to assist overseas contractors and EPC firms with project inspections, factory audits, and customs clearance. Our products can be bundled with mounting rails, brackets, and fasteners in the same container, offering a comprehensive, one-stop supply solution.
A: Yes. We can combine the production and packaging of aluminum alloy accessories with hot-dip galvanized or Zinc-Aluminum-Magnesium (Zn-Al-Mg) steel structures. This allows for a single customs declaration and a one-stop delivery of the complete PV mounting system, helping to reduce your procurement costs.
A: We offer OEM mold customization. Standard mold sampling typically takes 4–6 weeks; production schedules for large-volume orders can be negotiated. We support both small-batch prototyping and large-scale supply.
A: Yes. While the standard thickness is 8–10 μm, we can provide a thicker, 15–20 μm anodized coating for projects in coastal, high-salinity environments to ensure superior corrosion resistance.
A: Simply provide the roof tile type (e.g., standing seam, concealed-fix, or standard corrugated steel) and the profile dimensions, and we will match them with the appropriate clamps. For unique or non-standard profiles, we can develop custom molds based on your drawings.
A: Yes. We provide an MTC and a salt spray test report for every shipment, ensuring compliance with the requirements for engineering reviews and project inspections.
A: Install using the specified clamping torque, with EPDM rubber pads provided for cushioning; when clamped correctly, this will neither damage the component frames nor compromise the corrugated coating.
