Frequently Asked Questions (FAQ) – Premium Reverse-Folding Umbrella
1. Product Specifications
Q1: What are the key structural features of this umbrella?
Frame: 8-rib tension wire system with black EDP-coated steel ribs (electrophoretic deposition, 20μm thickness, 72hrs salt spray resistance).
Shaft: Reverse-folding steel shaft (collapses upward to minimize wet surface contact).
Runner: Black polymer (ABS/PC blend) upper/lower runners, tested for 5,000+ open/close cycles.
Q2: How does the "reverse-folding" design work?
The canopy folds outward when collapsed, trapping rainwater inside to keep users dry. The shaft retracts downward ("inverted") for compact storage (folded length: ~25cm).
2. Durability & Weather Resistance
Q3: Is this umbrella windproof?
Yes. The 8-rib tension wire structure distributes wind load across ribs, withstanding Beaufort 6 winds (12.5m/s).
EDP-coated ribs resist bending fatigue (tested to 120MPa stress).
Q4: Will the black coating on ribs peel off?
No. The electrodeposition coating (EDP) bonds chemically to the steel, passing 72hrs salt spray testing (ASTM B117).
3. Usage & Maintenance
Q5: How to dry the umbrella after rain?
Simply leave it partially open (reverse-folded) for 10-15 minutes. The outward-folded canopy accelerates drying by 50% vs traditional designs.
Q6: Can the tension wires break?
Unlikely. Wires are 0.6mm high-tensile nylon-coated steel (load capacity: 15kg per rib). Avoid forcing the ribs if obstructed.
4. Compliance & Sourcing
Q7: Is this umbrella RoHS/REACH compliant?
Yes. All materials (including EDP coating) are free of hexavalent chromium (CrVI) and heavy metals above EU thresholds.
Q8: What’s the MOQ and lead time?
MOQ: 300pcs (standard export packaging: 50pcs/ctn, 0.25CBM).
Lead time: 25 days after order confirmation.
5. Target Market & USP
Q9: Who is this umbrella best suited for?
Urban commuters: Compact folding (25cm) fits in backpacks.
High-rainfall regions: Reverse-folding design keeps water contained.
Corporate gifts: Custom logo printing available on canopy/shaft.
Q10: How does it compare to auto-open umbrellas?
Advantages:
More durable (no spring mechanism to fail).
Lighter (320g vs 400g+ for auto umbrellas).
Lower manufacturing cost (ideal for bulk orders).
