This engineered solution features 6061-T6 aluminum frames with reinforced multi-chambered profiles that meet Miami-Dade County Product Approval and ASTM E1886/E1996 standards for resistance to 180mph winds and 90mph wind-driven rain. Unlike conventional sliding doors with limited opening width, these bi-fold systems create unobstructed openings up to 12m wide when fully folded, seamlessly connecting indoor and outdoor spaces while providing category 5 hurricane protection. The precision roller system ensures smooth operation even after 10,000+ cycles, making them ideal for luxury residences and high-end commercial properties in hurricane-prone regions.
Storm-Resistant Construction: 3mm-6mm thick aluminum frames with stainless steel reinforcement in critical sections achieve impact resistance of 900J (equivalent to 2x4 lumber at 30mph) per ASTM F1996.
Superior Weather Sealing: Multi-point locking system (12+ lock points on large units) and EPDM gaskets achieve IP67 water tightness rating, preventing water intrusion even during 100mm/h rainfall.
Structural Performance: Withstands wind loads up to 5.0kPa and positive/negative pressure differentials of ±2.4kPa, exceeding Florida Building Code requirements for coastal high-velocity zones.
Smooth Operation: Heavy-duty stainless steel rollers with 200kg load capacity per panel require <10N force to operate, with self-aligning tracks that compensate for minor foundation movement.
Luxury Coastal Residences: Provides unobstructed ocean views with peace of mind in hurricane zones, increasing property values by 12-15% compared to non-certified doors in Florida markets.
Resort Properties: Creates flexible indoor-outdoor event spaces that can be securely closed during storms, maintaining operational continuity in hospitality settings.
Waterfront Restaurants: Large openings enhance dining experiences with waterfront views while ensuring patron safety during sudden weather events.
High-Rise Condominiums: Balcony installations meet stringent wind load requirements for high-elevation exposures, with noise reduction properties (STC 32) for urban environments.
Q: What certification is required for hurricane zones?
A: Our doors carry Miami-Dade NOA #17-0422.06 and Florida Product Approval #FL3241, meeting the highest standards for both wind resistance (180mph) and impact protection (Level D).
Q: How does the bi-fold mechanism perform in saltwater environments?
A: All hardware components use 316 stainless steel with 1000-hour salt spray resistance, and aluminum frames receive a marine-grade 120μm powder coating to prevent corrosion in coastal areas.
Q: What glass options are available for impact resistance?
A: We offer 6mm+ laminated impact glass (2 layers of glass with polyvinyl butyral interlayer) that remains intact after impact, with optional low-e coatings for U-values as low as 1.8 W/(m²·K).
Q: How long does installation typically take for large openings?
A: A 6m-wide system can be installed in 1-2 days by a 4-person crew, with factory-preassembled panels reducing on-site labor and ensuring proper sealant application.
