Engineered specifically to reduce dead weight in high-density urban areas. High structural load rating with customized profiles.
As the largest metropolitan economy in the world, Tokyo presents a unique architectural matrix. High-density skyscrapers, severe seismic threat indices, and stringent fire safety codes shape local construction regulations. For buildings exceeding 31 meters, the Tokyo Metropolitan Government enforces the installation of either an emergency rescue deck (Rooftop Emergency Heliport) or a rescue space under the Japanese Building Standards Act (Building Standards Act Article 129).
Traditional concrete rooftop helipads add immense dead weight (often over 150-200 tons depending on dimensions and reinforcement). In a zone prone to active seismic hazards (such as Kanto Plain's subduction zones), this top-heavy mass dramatically amplifies the lateral forces (Base Shear coefficient, Co) acting upon a building during an earthquake. Our aluminum profile helipads solve this by reducing the structure’s dead weight by up to 65% to 70% compared to concrete equivalents.
By employing high-tensile 6082-T6 or 6061-T6 aluminum alloys, Lvxing's helideck profiles achieve structural yield strength properties equivalent to steel but at one-third of the weight density (2.7 g/cm³ vs 7.8 g/cm³).
| Material Parameter | Structural Steel (Q355) | Reinforced Concrete | Lvxing Aluminum Profile (6082-T6) |
|---|---|---|---|
| Weight Density (g/cm³) | 7.85 | 2.40 | 2.70 (Approx. 65% lighter) |
| Yield Strength (MPa) | 355 | N/A (Tension weak) | 260 - 310 |
| Corrosion Resistance | Low (Requires painting/galvanizing) | Medium (Sulfate/rebar carbonation) | Excellent (Self-passivating oxide layer) |
| Installation Time (Tokyo Site) | 20-30 Days (Hot-work required) | 45+ Days (Wet concrete curing) | 5-10 Days (Modular interlocking) |
| Seismic Dynamic Loading Impact | High | Extremely High | Very Low |
Bridging premium raw material processing with precision engineering to serve the Japanese and global infrastructure markets.
Established in 2015 and located in Foshan City, Guangdong, LvXing Intelligent Equipment Co., Ltd. boasts a skilled R&D team with extensive experience. We leverage exceptional technical expertise to effectively transform customers' ideas into reality, consistently meeting their precise requirements.
We utilize premium Fenglu aluminum, offering a diverse range of profiles for flexible applications. Our extrusion lines, ranging from 800T to 20,000T, accommodate alloys 1xxx, 2xxx, 3xxx, 5xxx, 6xxx, and 7xxx, allowing us to produce shaped products with section dimensions up to 1.2 meters in width and 28 meters in length. These products are recognized for their precision and meticulous processing, finding broad application in aerospace, military, medical, and industrial sectors.
Our commitment to excellence is evident throughout the manufacturing process, rigorous quality control, thorough packaging, and efficient shipping procedures. This dedication has earned us recognition as a national excellent and honest enterprise, along with quality system certification in accordance with GB/T19001-2016/ISO9001:2015 standards.
We have obtained the "Special Aluminium Materials for Aerospace" Certificate. This ensures our profiles handle the dynamic and impact loads of heavy emergency response helicopters under rigorous structural stress cycles.
Utilizing high-quality Fenglu aluminum. Equipped with 800T to 20,000T extrusion lines, producing wide-section interlocking helipad deck components up to 1.2 meters wide and 28 meters long, reducing joints and weld vulnerabilities.
Our engineering staff brings over 15 years of practical R&D experience. We identify structural friction, thermal expansion, and localized wind shear issues specific to coastal cities like Tokyo before manufacturing.
Exporting structural profiles to Japan requires rigorous adherence to local regulations. Our manufacturing process conforms to global norms while strictly matching Japanese Industrial Standards (JIS) for aluminum components:
Our helipad decks feature a patented, screwless interlocking design that dramatically increases structural speed of assembly. The profiles incorporate deep drainage channels to prevent water accumulation during typhoons (frequent in Tokyo's late-summer seasons). Integrated landing safety net grooves are engineered directly into the perimeter profiles, allowing direct installation of safety nets without structural retrofitting.
Why do Japanese developers and general contractors (such as Obayashi, Kajima, and Shimizu Corporations) procure from our Foshan facilities? The answer lies in the unmatched concentration of the aluminum supply chain in South China. By partnering with Fenglu Aluminum, the raw material is processed at scale, bypassing high local production costs in Japan.
Logistically, Foshan's close proximity to Nansha Port (Guangzhou) and Shenzhen Port allows us to offer short shipping times. A standard ocean freight container can reach the Port of Tokyo within 5 to 7 days, guaranteeing that tight Tokyo high-rise construction schedules are met on time.
Aluminum helidecks and perimeter nets have various applications across critical municipal and commercial structures in Japan's capital:
Rooftop rescue decks on governmental, municipal, and ward offices in Shinjuku, Chiyoda, and Shibuya. Lightweight decks reduce building load, preserving structural integrity for post-earthquake search-and-rescue flights.
Hospital rooftop helidecks certified for rapid patient transport. Fully compliant with aviation safety nets, obstacle lighting profiles, and integrated fire extinguishing conduits.
Supporting Tokyo’s future "Smart City" goals. Our light-alloy platforms are ideal for upgrading existing commercial building rooftops into ready-to-use eVTOL skyports.
