The Square Double-Vented Center-Pole Outdoor Patio Umbrella with Crank Tilt, featuring a warm terracotta canopy, delivers structured, high-coverage shade for outdoor spaces with a clean, geometric silhouette. When fully open, it forms a perfectly square shaded footprint, with a matching 600 x 600 mm double-vented panel centered at the canopy top, finished with a die-cast aluminum finial coated to match the brushed silver powder-coated center pole. The crank handle sits 1100 mm above ground for accessible operation, while the canopy edge rests 2100 mm above ground, with two-position height adjustment that shifts clearance by 100 mm to accommodate varying seating arrangements. The two-piece center pole measures 48 mm in diameter, supporting 8 powder-coated steel ribs extending 1500 mm per side to hold the canopy taut. The main canopy is constructed from 280 gsm solution-dyed polyester with a PU waterproof coating, sewn with UV-resistant polyester thread at 8 stitches per inch, with reinforced stitched seams on the top vent panel. The frame combines a 1.2 mm thick powder-coated aluminum center pole, zinc-plated steel crank hardware with an ABS plastic handle, and glass-reinforced nylon hub and rib connectors secured with M6-M10 fasteners with at least two fixing points at each major joint, for a net weight of 15 kg without a base. The hand crank mechanism opens and closes the canopy smoothly over 8 full rotations, while a push-button collar tilt adjusts the canopy angle up to 45 degrees to block low-angle sun. The double-vented top panel allows upward airflow to cut down on wind lift and frame stress, rated for secure operation in wind speeds up to 38 km/h, and the canopy fully collapses against the pole for compact storage. The polyester canopy carries a UPF 50+ UV protection rating with 1000 hours of colorfastness, and the two-piece pole enables tool-free assembly, fitting standard patio umbrella tables with 50 mm or larger center holes. It is sized to comfortably shade 6 people, making it suitable for residential patios, home gardens, courtyards and pool decks, as well as commercial cafe, restaurant and hotel outdoor seating, market stalls, pop-up events, public park seating zones, apartment complex courtyards and campus outdoor spaces. For procurement, note that the product ships unbranded as model PU-ST30-CT-TER across 2 cartons per set, with a packaged gross weight of 120 kg and 0.8 m³ packaging volume, requiring 40 minutes of assembly time per unit. Purchase must include a separate 50 kg weighted marble or concrete base, as bases are not included, and units must be placed on flat, level hardscape surfaces, closed and secured during high wind or thunderstorms. The canopy fabric is not designed for permanent exposure to extreme weather, so seasonal storage is recommended to extend service life.
