An aluminum alloy 90° outside corner is a fitting or trim piece designed to form a right-angle (90-degree) external corner in structures that use aluminum components. It is commonly used in construction, rainwater drainage systems, siding, and architectural cladding, where two flat panels or surfaces meet on an outside (external) corner.
Gutter Systems:
Installed at corners where two sections of gutter meet on the outside of a building.
Ensures smooth water flow around corners without leaks.
Wall Cladding & Siding:
Provides a clean, protective transition on external building corners.
Enhances aesthetics and protects exposed panel edges.
Trim Work:
Decorative or protective aluminum trim for windows, doors, or edge finishes.
1. Material Sourcing
Aluminum Alloy: Use high-quality aluminum alloy that meets industry standards. The chosen material should offer excellent strength, corrosion resistance, and long-term durability for outdoor conditions.
Additives and Coatings: Apply protective treatments such as anodizing or powder coating to increase resistance to weathering and UV degradation. Ensure coatings are uniform and securely bonded to the surface of the pipes.
2. Design and Prototyping
Customization: Aluminum rainwater pipes come in various diameters, wall thicknesses, and fittings (e.g., bends, connectors, end caps). Customize dimensions and features based on client specifications and building architecture.
Prototyping: Develop prototypes before large-scale production to test water flow capacity, structural integrity, and installation compatibility. This helps identify and correct design flaws early.
3. Manufacturing Process
Extrusion: Most aluminum pipes are manufactured through the extrusion process, where heated aluminum billets are pushed through a die to achieve a consistent circular or rectangular cross-section.
Tooling & Mold Maintenance: Keep dies and extrusion tools in top condition to ensure precision and reduce defects.
Temperature Control: Maintain optimal temperature settings throughout the extrusion and cooling phases to achieve consistent thickness and avoid warping.
Secondary Forming (Bends & Elbows): Use bending machines or stamping processes to fabricate pipe components like elbows and connectors with high accuracy.
4. Quality Control
Dimensional Inspection: Measure outer diameter, wall thickness, and overall length to ensure they conform to specified tolerances.
Strength Testing: Conduct mechanical tests, including pressure, bending, and impact resistance, to verify structural integrity.
Corrosion Resistance: Perform salt spray or weathering tests to confirm long-term performance in outdoor environments.
Leak & Flow Testing: Verify that joints, seams, and connections maintain watertight integrity under simulated rainfall conditions.
5. Logistics and Distribution
Inventory Management: Monitor raw material levels and finished product inventory using digital systems to ensure efficient production flow and timely deliveries.
Packaging: Use protective, non-abrasive packaging materials to prevent scratches, dents, and deformation during transport. Clearly label each package for ease of identification and installation.
Shipping: Secure and stack aluminum pipes properly in transport vehicles to avoid bending or surface damage. Optimize routes for cost-effective and timely delivery.
6. Customer Feedback and Improvement
Performance Monitoring: Gather field data and client feedback post-installation to assess durability, ease of use, and any operational issues like leakage or blockage.
Continuous Improvement: Analyze production data and customer input regularly. Introduce automation and modern manufacturing technologies where applicable to increase consistency and lower costs.
7. Compliance and Certifications
Building Codes & Standards: Ensure that all aluminum rainwater pipes conform to local and international construction codes and performance standards.
Certifications: Acquire recognized certifications such as ISO, ASTM, or equivalent regional marks to validate quality, environmental safety, and manufacturing reliability.

1. Preparation and Materials Required
Aluminum rainwater pipes (clean, undamaged, and ready for packaging)
Bubble wrap or foam padding for surface protection
Stretch film or shrink wrap for securing pipe bundles
Corrugated cardboard or protective corner guards for edge protection
Zip ties or packing tape for bundling pipes
Durable strapping (for larger or heavier bundles)
Wooden crates or heavy-duty cardboard boxes (recommended for bulk or long-distance shipments)
Pallet (optional, for large-volume or freight deliveries)
2. Packing Process
a. Clean and Inspect
Ensure all aluminum pipes are clean, dry, and free from surface damage. Inspect each piece for dents, bends, or scratches prior to packing.
b. Bundle Pipes
Group pipes of the same size and length together.
If the pipe design permits, nest them to minimize movement and save space.
Secure the bundles using zip ties, tape, or strapping. Take care not to overtighten to avoid deforming the pipes.
c. Protect Surfaces and Ends
Wrap each bundle in bubble wrap or foam padding to protect against impact.
Use protective corners or corrugated cardboard on both ends and along sides to shield the edges from crushing or abrasions.
d. Wrap the Bundle
Secure the entire bundle using stretch film or shrink wrap to hold the pipes firmly in place during transport. Ensure all pieces are tightly wrapped and stable.
3. Delivery Guidelines
a. Labeling
Apply clear, water-resistant labels to each bundle or package.
Include appropriate handling instructions such as "Fragile," "This Side Up," or "Do Not Stack" as needed.
b. Vehicle Loading
Position the pipes flat and ensure proper support throughout transit. Avoid any overhang or sagging.
Do not stack heavy items on top of the aluminum pipes.
For pipes over 10 feet in length, ensure the delivery vehicle has adequate space and tie-down points to secure the load safely.
c. Use of Pallets (For Bulk Orders)
Place bundles evenly on pallets to ease handling and prevent shifting.
Strap the bundles securely to the pallet, then shrink-wrap the entire load for added stability and protection during shipping.
