The Square Dual-Tone Curved-Arm Outdoor Cantilever Patio Umbrella with Weighted Base (model CU-SQ10-CANT-UMB-01) is an unbranded freestanding shade solution designed for flexible outdoor use, defined by a balanced, streamlined silhouette that avoids obstructing sightlines across gathering spaces. Its offset cantilever structure supports a perfectly square canopy, with an 8-rib framework creating taut, even fabric tension across the full coverage area. The dual-tone design pairs a coated upper canopy surface with a soft beige underside, accented by a breathable mesh vent at the canopy apex, while the smoothly curved support arm connects to a thick vertical support pole anchored by a low-profile matte black weighted base. Durable, weather-facing materials form the core of the umbrella’s construction. The frame uses powder-coated aluminum alloy for the vertical pole and curved cantilever arm, paired with powder-coated steel canopy ribs for rigid support, with component thickness calibrated to load-bearing requirements. The canopy uses 281 gsm solution-dyed polyester, with a PA coating on the top surface delivering UPF 50+ UV protection, Grade 4 AATCC 22 water repellency, and 1000 hours of fade resistance. The crank mechanism uses reinforced nylon housing with internal steel gears, and the pre-filled base combines a UV-stabilized HDPE resin shell with high-density concrete composite ballast to secure the structure. Practical functions are engineered for easy, adaptable use. A side-mounted hand crank positioned at accessible standing height operates the canopy lift, with 6 locked tilt positions and smooth 360-degree rotation around the vertical pole, both featuring auto-lock at every adjusted position to track shifting sun angles across seasons. The built-in top vent allows passive air flow to reduce wind lift, the detachable canopy attaches via rib pockets for straightforward fabric replacement, and the freestanding pre-filled base eliminates the need for permanent surface anchoring. The umbrella delivers shade for up to 6 people, with a 2100 mm canopy edge clearance that accommodates standard seating heights without obstruction. This umbrella fits a wide range of outdoor settings, including residential backyards paired with 6-person dining sets, poolside chaise lounge zones, cafe and restaurant sidewalk patios, garden conversation areas, and wood or composite raised deck surfaces. Procurement teams should note the unit ships in 2 cartons per set, with a packaged gross weight of 120 kg and 0.8 m³ packaging volume, requiring 40 minutes of assembly per unit. Operation should adhere to the maximum recommended 38 km/h wind speed to prevent structural damage, and the 58 kg total product weight relies on the integrated 54 kg base ballast for stable freestanding placement.
