Engineered structural profile decking assemblies certified for standard and specialized architectural applications across Northern California.
Why modern urban engineering demands modular, high-strength aluminum decking over concrete and steel.
The San Francisco Bay Area represents one of the most demanding engineering landscapes globally. Driven by aggressive geological realities, strict municipal building codes, and proximity to a marine environment, structural engineers, architects, and municipal developers face constant challenges. When designing rooftop helicopter landing pads (helipads) for major regional trauma centers, high-density residential towers, and offshore safety decks, materials must meet exceptionally high standards for strength, weight, and corrosion resistance.
Seismic Mitigation (California Building Code Title 24): San Francisco lies in a region of high seismic hazard (Zone 4) governed by the Hayward and San Andreas fault lines. According to ASCE 7 structural design criteria, the dead load of a building dictates the inertial forces generated during seismic acceleration. Traditional concrete-slab rooftop helipads add massive structural weight to high-rise towers. A structural aluminum alloy assembly reduces the dead weight of the rooftop landing deck by up to 50% compared to steel and 70% compared to reinforced concrete. This structural weight savings reduces seismic shear forces, decreases the foundation's load-bearing demand, and cuts down on expensive structural steel reinforcements throughout the entire vertical frame of the building.
Marine Atmosphere Corrosion Protection: San Francisco's coastal position subjects rooftops and marine platforms to continuous salt spray, high moisture, and coastal fog. In this highly corrosive environment, traditional carbon steel decks suffer fast oxidation and structural breakdown, requiring constant maintenance, surface sandblasting, and epoxy recoating. Extruded aluminum profiles using high-performance 6000-series (such as 6005A-T6 or 6082-T6) and aerospace-grade 7000-series alloys feature excellent natural corrosion resistance. The aluminum forms a stable surface oxide layer that resists chloride penetration. For extended durability, specialized anodization (MIL-A-8625 Type III Hardcoat) ensures these structural elements require minimal maintenance throughout a service life exceeding 30 years.
Engineered performance values that satisfy FAA Advisory Circular 150/5390-2C and local structural calculations.
Lvxing Intelligent Equipment utilizes premium-grade Fenglu aluminum, the industry standard for high-integrity structural extrusions. Our advanced extrusion facility operating out of Foshan utilizes hydraulic presses ranging from 800-ton capacity for high-tolerance components, up to a massive 20,000-ton press. This extrusion capacity enables the production of single, continuous, hollow-core interlocking profile profiles up to 1.2 meters wide and 28 meters long, minimizing joint fatigue and structural assembly failures.
| Alloy Designation | Temper Status | Tensile Strength (MPa) | Yield Strength (MPa) | Elongation (%) | Primary Application |
|---|---|---|---|---|---|
| 6061 | T6 | ≥ 290 | ≥ 240 | ≥ 10 | Main framing structures, brackets, supporting trusses |
| 6005A | T6 | ≥ 270 | ≥ 225 | ≥ 8 | Interlocking main deck profiles, integrated dynamic landing surfaces |
| 6082 | T6 | ≥ 310 | ≥ 260 | ≥ 10 | Heavy-load coastal or offshore decks with high shear load criteria |
| 7075 | T6 | ≥ 540 | ≥ 480 | ≥ 7 | Aerospace-grade high stress components, military tactical pads |
Our engineered structural profiles utilize an interlocking tongue-and-groove joint profile design that distributes heavy impact loads over multiple profiles. When a 12-ton helicopter (such as the Sikorsky S-92) lands, the localized wheel load is distributed dynamically through neighboring profiles, preventing localized denting or structural deformation. Our profiles are calculated for elastic limits that exceed the FAA’s dynamic drop factor requirements of 3.0 times the maximum takeoff weight (MTOW).

How our modular profile decks are deployed to resolve local zoning, weight limits, and geographic constraints.
1. Trauma Center & Medical Rooftop Decks: In the city of San Francisco, rooftop trauma heliports (such as for medical transport helicopters) must feature highly reliable designs. Weight restrictions on older, existing hospital concrete frames often prevent adding a concrete landing pad. Our customized lightweight aluminum profile structures can be mounted directly onto existing load-bearing columns. A retrofitted aluminum deck allows regional hospitals to add critical helipad capabilities without the need for extensive foundation reinforcements.
2. Marine Port & Coast Guard Emergency Facilities: For waterfront environments like the Port of San Francisco, Oakland, or Alameda, air-sea rescue helipads face continuous exposure to salt water. Traditional concrete decks absorb moisture, resulting in internal rebar rust and concrete spalling. By utilizing seawater-resistant extruded aluminum profiles, marine landing surfaces remain clear of rust and corrosion, providing a durable platform for emergency responder helicopters and marine supply transport.
3. Dense Commercial High-Rises & Seismic Resilience: High-rise developments in San Francisco are designed to sway during seismic activity. An aluminum helipad, assembled using modular profiles, introduces less mass at the building's highest point, reducing the top-heavy inertial movement during an earthquake. Our locking tongue-and-groove profile designs accommodate minor flexing, absorbing structural movements without cracking or losing load capacity.
The next generation of vertical transport decks in the San Francisco Bay Area.
As the Silicon Valley and San Francisco regions prepare for the next step in urban transportation, the deployment of eVTOL (Electric Vertical Takeoff and Landing) aircraft is transitioning from concept to reality. The regional transport network of the future will rely on decentralized urban vertiports, constructed on rooftops, parking structures, and marine docks. These vertiports require rapid structural deployment, modular designs, integrated electrical containment, and lightweight materials.
Our extruded aluminum profiles are well-suited for vertiport engineering. They allow for the integration of heating conduits to prevent winter icing, conduits for battery charging cables, and integrated landing LED channels directly within the profile extrusions. Furthermore, because aluminum is 100% recyclable, using these profiles supports LEED certification goals for new developments in California. By sourcing advanced aluminum systems from our Foshan facilities, Bay Area real estate and technology developers can construct durable infrastructure to support the future of urban aviation.
