High-durability marine-grade aluminum systems certified to meet CAA-DK, CAP 437, and EASA regulatory compliance across Danish territorial waters and municipal super-hospitals.
Denmark, strategically positioned at the gateway of the Baltic and North Seas, represents one of the world's most demanding environments for marine, offshore wind, and medical aviation infrastructure. With the rapid expansion of offshore wind hubs like Esbjerg and the deployment of massive offshore converter stations, helicopter transport has become critical for logistical and rescue operations. In parallel, Danish municipal healthcare reforms have resulted in the construction of regional "Super-Hospitals" (such as Rigshospitalet and Aarhus University Hospital), each demanding state-of-the-art rooftop helipads.
Operating in these corrosive, maritime climates requires structural systems that can withstand extreme wind forces, marine salinization, and rapid temperature changes without structural degradation. In Denmark, traditional steel helidecks are increasingly replaced by premium aluminum alloys. Structurally engineered aluminum offers lightweight advantages, zero maintenance requirements in C5-M marine environments, and high elasticity to absorb dynamic landing loads. Furthermore, compliance with the Civil Aviation Administration Denmark (Trafikstyrelsen), EASA rules, and international standards such as CAP 437 is mandatory, requiring perimeter safety net systems to survive rigorous drop tests and continuous environmental exposure.

Translating raw engineering ideas into high-precision, certified structural products since 2015.
Established in 2015 in Foshan City, Guangdong, LvXing Intelligent Equipment Co., Ltd. features an advanced R&D and engineering department focused on high-performance structural systems. We utilize premium Fenglu aluminum, offering a diverse range of high-alloy profiles for complex civil, marine, and aerospace operations. Our extensive factory facilities house heavy extrusion lines ranging from 800T to 20,000T. This enables the fabrication of high-spec alloys across the 1xxx, 2xxx, 3xxx, 5xxx, 6xxx, and 7xxx series, with dimensions reaching up to 1.2 meters in cross-section width and 28 meters in single-span profile length.
LvXing's commitment to quality control is verified by our compliance with GB/T19001-2016 and ISO9001:2015 international quality standards. By integrating robust metallurgical science with mechanical engineering, our helipad structures and perimeter safety net systems maintain exceptional safety profiles under extreme loads, earning trust among global engineering partners and Danish contractors alike.
Why marine contractors, wind farm developers, and hospital structural engineers specify LvXing systems.
We hold official "Special Aluminium Materials for Aerospace" certifications. Every batch of aluminum used for helidecks and safety nets undergoes trace-element analysis to prevent micro-fracturing under stress.
Utilizing massive 20,000T extrusion lines to process heavy structural alloys (including marine 5xxx, load-bearing 6xxx, and high-tensile 7xxx series). We deliver complex cross-section components up to 28m long.
Our engineering team has 15 years of technical expertise. We map out structural load simulations, wind shear variables, and safety margin calculations to prevent failure modes prior to manufacturing.
Understanding CAP 437 compliance, shear force limits, and alloy behaviors in salt-spray zones.
The Danish North Sea sector is classified under ISO 12944 as a C5-M (Very High Marine) corrosive environment. Standard structural steel, even with hot-dip galvanization, degrades quickly, leading to micro-cracking and loss of load capacity. We utilize targeted aluminum-magnesium-silicon alloys (specifically 6082-T6 and 6061-T6) for extruded helipad deck planks and support frames.
Alloy 6082-T6 is highly valued in Northern Europe for its superior structural strength and exceptional corrosion resistance. In comparison to 6061, 6082 has higher tensile strength (typically 310 MPa vs 290 MPa) and better yield strength (260 MPa vs 240 MPa). For structural elements exposed to severe fatigue, such as the perimeter safety net support arms, we integrate 5xxx series alloys (like 5083-H112) for welded parts due to their superior performance in direct marine spray.
According to CAP 437 regulations, helideck perimeter safety nets must be installed around the landing area to catch personnel who may fall. The safety net must not project above the level of the landing area to avoid interfering with helicopter operations. LvXing manufactures both manual and electric motorized folding systems:
Perimeter safety nets must absorb the kinetic energy of a falling person without failing. Standard compliance mandates that the net frame and mesh withstand a drop test of a 100kg body (or sandbag) falling from a height of 1 meter. Our safety net systems use high-tensile 316 stainless steel cable mesh combined with structural 6082-T6 aluminum frames. This design distributes impact forces outward to prevent trampoline rebound effects, which could throw a person back toward the platform edge.
