Detail and Assembly Diagram
1-Application Scenario
|
1. High-Load Sloped Roofs The AS-DR-04 D-rail is ideal for sloped roofs in regions with strict environmental demands. Its robust D-nut channel provides superior structural strength to withstand heavy snow and high wind loads, ensuring long-term safety and stability. 2. Versatile Roofing Configurations Highly adaptable to tiled and corrugated metal roofs, it is available in square and rectangular profiles. It seamlessly supports both traditional railed and modern rail-less setups, offering flexible and customized solutions for diverse architectural requirements. 3. Fast & Labor-Efficient Projects Engineered for quick assembly, its adjustable D-channel allows flexible clamp positioning without pre-drilling. This significantly reduces labor time and installation costs, making it highly efficient for medium to large-scale solar deployments. |

FAQ
1.Will the AS-DR-04 fit my roof type, and can it withstand heavy wind and snow loads?
Yes. The AS-DR-04 is designed primarily for metal / tin sheet roofs — including corrugated and trapezoidal profiles — and also adapts to tiled roof configurations. Its D-nut channel structure provides enhanced load-bearing capacity, making it a proven choice for high-load sloped roofs in regions with strict wind and snow load requirements.
- Standard profile: W28.5 × H44 mm (customizable dimensions available)
- Available in square and rectangular profiles to match different roof structures
- Structural compliance verified to ASCE 7-10 (US), AS/NZS (Australia/New Zealand), and JIS (Japan)
Shopping tip: Send us your roof sheet profile drawing and local wind/snow load code — our engineers will confirm rail span and clamp layout for your project site.
2.How does the D-rail design make installation faster and reduce labor costs?
The rail features an adjustable D-channel that lets you position solar clamps anywhere along the track without pre-drilling — simply slide the D-nut into place and lock it down.
- No drilling or measuring per clamp position — 50%+ faster mounting vs. fixed-hole rails
- Compatible with both traditional railed and modern rail-less setups
- Ideal for medium and large-scale projects where labor hours directly drive cost
Shopping tip: If your crew is new to D-channel rails, ask us for the Installation Manual — it includes assembly diagrams and component options for each roof scenario.
3.What material and finish are used, and how long will the rail last outdoors?
The AS-DR-04 is extruded from AL6005-T5 structural-grade aluminum — the same alloy class specified in international solar mounting standards — with an anodized coating above 10 μm for long-term corrosion resistance.
- Designed service life: 25 years
- Backed by a 20-year guarantee period
- Finish options: silver or black anodized (customizable to match panel frames and roof aesthetics)
Shopping tip: For coastal or high-humidity projects (e.g., Southeast Asia, island markets), the ≥10 μm anodized layer is the key spec to check — thinner coatings are the #1 cause of early rail corrosion in salt-spray environments.
4.Which certifications does the AS-DR-04 hold, and are they valid for my market?
The product carries a full set of internationally recognized certifications and test reports:
- ISO — quality management system
- CE — European market conformity
- SGS — third-party material & performance testing
- AS/NZS 1170 — Australia & New Zealand structural standards
- JIS — Japanese Industrial Standards
Shopping tip: If your project requires bank financing or grid-connection approval, certification documents are usually mandatory — request the full certificate pack with your quotation.
5.What are the customization options, lead times, payment and shipping terms?
Sold per meter or per piece, fully flexible for both sample orders and project-scale volumes:
- Lead time by quantity: 1–1,000 pcs: 1–7 working days · 1,001–5,000: 7–10 days · 5,001–10,000: 10–15 days · over 10,000: negotiable
- Shipping: From Xiamen Port, China — 7–15 days for LCL, about 20 days for FCL
- Payment: 100% T/T or L/C at sight
- Customization: Custom lengths, dimensions, and colors (silver / black) available
- Packaging: Inner wrapping paper/film + outer wooden case for ocean freight protection
Shopping tip: Planning a large project? Share your bill of quantities — we can consolidate rails, clamps, and roof hooks into one FCL shipment to cut your per-watt logistics cost.
