PVC 90° gutter corners are essential components in rooftop rainwater drainage systems. These inside and outside corner fittings are designed to seamlessly connect horizontal plastic gutters around corners of buildings, ensuring a continuous path for rainwater flow and preventing leaks or overflow.
Material Type: Manufactured from rigid unplasticized polyvinyl chloride (uPVC), these 90-degree corner pieces are known for their strength, weather resistance, and long-lasting performance.
Weather & UV Resistance: These gutter corners are engineered to withstand outdoor exposure. The material resists degradation from sun (UV) exposure and extreme weather, making them ideal for long-term outdoor applications.
Chemical Resistance: Resistant to many chemicals typically found in urban and industrial rainwater, ensuring they maintain performance and appearance over time.
Standard Fit: Compatible with standard PVC rain gutter systems, usually in sizes such as 75mm, 100mm, 125mm, and 150mm.
Inside and Outside Options: Available in both inside corners (for internal roof angles) and outside corners (for external building edges).
Smooth Integration: Designed to match factory-supplied PVC gutters, providing a watertight and seamless joint at every 90-degree turn.
90° Inside Corner: Guides rainwater flow around inward angles of the building, typically where two walls meet at an inner corner.
90° Outside Corner: Facilitates water redirection at external corners of the roof, preventing spillover and protecting wall surfaces.
Universal Fitment: Easily connects with standard gutter profiles for residential, commercial, and industrial buildings.
Leak Prevention: Precisely molded to ensure tight sealing and accurate fitting, reducing the risk of leaks at vulnerable junction points.
Lightweight and Easy to Install: These plastic corners are much lighter than metal fittings, making them easy to handle and quick to install-ideal for both DIY and professional projects.
Durability: With excellent resistance to rust, corrosion, and weather damage, these corners ensure long-term protection for your rainwater system.
Low Maintenance: Requires minimal upkeep due to the non-corrosive, stain-resistant properties of uPVC.

Here's a breakdown of how we manage our PVC gutter ( accessories) production effectively:
PVC Resin: Ensure you are sourcing high-quality PVC resin that meets industry standards. The resin should be durable, resistant to weather conditions, and UV-stable.
Additives: PVC gutters often contain additives like stabilizers (to resist UV rays), plasticizers (for flexibility), and impact modifiers. Ensure these are selected properly to optimize the performance of your product.
Customization: Depending on customer requirements, you might need to create different designs and sizes (e.g., standard gutters, fascia brackets, elbows). Design your gutter profiles and accessories accordingly.
Prototyping: Before mass production, create prototypes and test them for functionality, durability, and ease of installation. Prototypes allow you to identify potential issues in design.
Extrusion: Most PVC gutters are made via the extrusion process, where heated PVC material is forced through a mold to form long, continuous sections of gutters.
Tooling: Ensure your extruder machine is calibrated and your molds are in good condition to prevent defects.
Temperature Control: Maintaining proper temperature settings is key for consistent thickness and quality.
Injection Molding: For accessories like gutter hangers, elbows, or end caps, injection molding may be used. Ensure precise molding equipment for these parts.
Dimensional Inspection: Regularly check the dimensions of the gutters to ensure they meet the required specifications.
Strength Tests: Test the durability of the material, including bending and impact tests, to ensure the PVC gutter hangers and other components can withstand typical weather conditions.
UV Testing: To verify UV resistance, subject products to accelerated aging tests. This will ensure the gutters won't degrade or discolor after prolonged exposure to sunlight.
Leak Test: Test gutter joints to make sure they're properly sealed and don't leak when water is running through them.
Inventory Management: Use efficient inventory management to track raw materials, production schedules, and finished products. You want to make sure you have enough raw materials to meet demand without overstocking.
Packaging: Packaging should protect the gutters during transportation. It should also be easy for the end customer to open and install the product.
Shipping: Optimize shipping logistics to minimize costs and improve delivery times. Ensure gutters are stored in a way that prevents warping or damage.
Monitoring Performance: After installation, monitor how well the product performs. Are customers experiencing issues like sagging, leaks, or discoloration? Customer feedback is crucial to making adjustments and improving the product.
Continuous Improvement: Regularly assess production efficiency, quality control measures, and customer feedback to implement improvements. Automation in the production process, if feasible, can also help improve consistency and reduce costs.
Ensure your PVC gutter products meet local building code requirements and environmental standards.
If necessary, get your product certified for specific standards like ASTM, ISO, or other regional certifications for quality and safety.
Efficiency: Streamline production processes to keep costs down while maintaining quality. Invest in technology and training for workers.
Environmental Impact: As sustainability becomes a bigger issue, consider adopting eco-friendly practices like recycling scrap PVC or using recyclable packaging materials.
Customer Service: Offer support for installation or repairs and keep a line open for customer feedback.

Use clear, water-resistant labels on each package or bundle.
Include necessary handling instructions, such as "Fragile," "Do Not Stack," "This Side Up," or any specific information relevant to the type of accessory.
b. Load Strategically
When loading onto transport vehicles, place bundles of accessories flat and evenly supported.
Avoid stacking heavy items on top of the packed accessories to prevent deformation.
Ensure that the vehicle supports the accessories, especially larger or longer items like downspouts or gutter elbows, and use adequate tie-down points for secure transport.
c. Use Pallets (For Bulk Orders)
Stack the bundled accessories evenly on a pallet to ensure stability and prevent shifting during transit.
Strap the bundles securely to the pallet using strong strapping to avoid any movement.
For bulk orders, shrink wrap the entire pallet to protect the contents and ensure safe handling during shipping, especially when using a freight carrier.
