Product Overview (What)
Definition: A retractable/cut-to-length aluminum screen/cover designed for “3-inch” gutters or nearby widths, commonly used to block leaves and debris from entering the gutter and hindering drainage.
Key selling points: Lightweight, corrosion‑resistant, customizable mesh size and thickness, easy installation (clips/screws or direct attachment), supports OEM/ODM and large‑volume supply.
Typical Product Specifications (Customizable)
• Adapted gutter width: standard 3 inches (about 76 mm), can be designed to be expandable/foldable to fit 70–100 mm gutters.
• Length: typically offered in rolls (30–100 m/roll) or cut lengths (1–3 m sections).
• Mesh size: common hole diameter/spacing ranges from 0.8–5.0 mm (adjustable for protection level and drainage rate).
• Gutter guard thickness: 0.3–1.0 mm (0.012–0.04 in) is common; heavier or commercial grades available.
• Material grade: aluminum alloys (commonly 1000 series such as 1050, 1060) or custom alloys.
• Surface treatment: Anodized (anodized finishes with thickness 5–25 μm), Powder coating (multi‑color), Electrophoresis, or bare aluminum.
• Weight and strength: depend on thickness and mesh structure; sample data sheets can be provided on request.
• Packaging: carton/pallet/roll packaging customizable, with client branding and labels.

Material & Surface Treatment (Corrosion Resistance and Aesthetics)
• Aluminum advantages: lightweight, formable, cost‑effective, and corrosion‑resistant compared with ordinary steel; well suited for coastal or humid environments when paired with coatings.
• Surface options comparison:
• Anodize: increases corrosion resistance and weather resistance; color options and wear resistance are good for long‑term outdoor use.
• Power coating (powder coating): many colors, strong adhesion, good weather resistance; ideal when appearance matters.
• Bare aluminum: lowest cost, easy to recycle; may require more maintenance or thicker material for longer life.

Customization & OEM Services
• Custom items: width/length, mesh size, sheet thickness, edge finishing, bending/flanging, fixtures/screws, packaging, branding (OEM), labeling, styles and colors.
• MOQ (typical references): standard in‑stock can be as low as 100–500 pieces; custom styles generally 500–2,000 pieces, depending on process and material.
• Samples: usually free or paid; sample lead times 3–10 days, mass production 15–35 days depending on order size.
• Capacity & delivery: large manufacturers with continuous production lines can output tens of thousands of meters per month; supports sea/air/express shipments; FOB/CIF/EXW terms available.

Quality Control & Compliance
• Certifications: many suppliers hold ISO 9001; they can provide material test reports, salt spray tests (corrosion resistance), tensile/hardness tests, and third‑party inspection reports (e.g., SGS, BV, Intertek).
• Incoming/production quality checks: materials inspection → online dimension/thickness checks → surface finish checks → random sampling and final packaging inspection → shipping QC report.
Tip: request material certificates (MTC), surface treatment reports, and long‑term exposure test data to assess weather resistance. For related documents, see the Product Documentation Download Page and the End-to-End Service & Guarantee System.
Installation & Compatibility
• Installation methods: clip fittings, self‑tapping screws, adhesive/sealant, or snap‑in features. Suppliers typically provide installation clips and guidelines (HowTo).
• Key steps: measure gutter width and edge, determine fixed spacing, arrange in order and leave expansion gaps for thermal movement, use waterproof mats or foam to reduce noise and prevent scratches.
• Compatibility: fits traditional aluminum gutters, PVC/UPVC, galvanized steel, and some custom gutter shapes; complex gutters may require on‑site measurement and custom fabrication.
• Maintenance: inspect every 6–12 months, remove larger debris, replace damaged sections promptly. For installation tutorials, see the Video Page. You may also view edge treatments on the Aluminum Grass Edging page for related applications.
Pricing, MOQ & Delivery
• Price drivers: material grade and thickness, surface treatment (anodized/powder), mesh precision, customization (bending/punching), packaging, order quantity, shipping method, and trade terms (FOB/CIF).
• Process: provide a requirements list (specs, quantity, surface, destination port) → receive FOB/EXW quotes → confirm samples → sign contract and pay a deposit → start production → QA and shipping.
• Typical lead times: in‑stock 3–10 days; customized batches 15–35 days (more time for complex finishes or large orders); expedited production may be available.
• Shipping: mostly sea freight LCL/FCL, also air or express for samples; suppliers commonly offer FOB China port quotes and door‑to‑door services.

FAQ
Q: What is a 3‑inch expandable aluminum gutter guard?
A: A retractable/cut‑to‑length aluminum mesh guard designed for 3‑inch (about 76 mm) gutters. It protects against debris, resists corrosion, and is easy to install; you can customize mesh size and thickness.
Q: What material options are available?
A: Common choices are aluminum alloys in the 1000 series (such as 1050 or 1060) or specific alloys. Finishes include Anodize, Power coating, electrophoresis, or bare aluminum.
Q: Do you offer OEM/customization?
A: Yes. Customization covers width, length, mesh, thickness, finishes, packaging, and branding. Small sample quantities are available for testing, with options for large‑scale production.
Q: What are typical lead times and MOQ?
A: In‑stock samples usually take 3–10 days; customized batches 15–35 days. MOQ varies by design and finish, commonly in the 100–2,000 piece range—please confirm with the supplier.
Q: How can I ensure quality and certification?
