X-TEND stainless steel mesh is light, robust, and transparent. An endless production of X-TEND is possible – hence also the name X-TEND = to extend. Helipads are commonly built on the vessel deck, rooftop and other open areas. It is absolutely vital to ensure the safety of technicians and passengers, and our stainless steel cable mesh is engineered precisely for this.
Stainless steel cable mesh made from AISI 304/316/304L/316L wire rope combines high strength with low weight, excellent transparency and outstanding corrosion resistance. Correctly specified Flexible Stainless Steel Mesh Netting will protect people, aircraft and structures for decades – but ignoring a few key details can create serious safety and financial risks.
Flexible Stainless Steel Mesh Netting for Marinas and Helidecks
Flexible Stainless Steel Mesh Netting is woven from stainless steel wire rope into a resilient net that can be formed into flat or three-dimensional shapes. The stainless steel wire rope mesh flexes under load, absorbing energy from impact while preventing people or objects from falling through. It is ideal for helideck perimeters, offshore platforms, marina balustrades, stairways, bridges and zoo enclosures.
Fact #1 – Mesh geometry fact that controls real-world safety
Mesh aperture, angle and wire rope diameter together define how the net behaves under impact. If the aperture is too large or the angle too shallow, objects can slip through or the mesh can deform excessively, creating dangerous openings. Correct combinations of wire rope diameter, mesh aperture and angle degrees deliver safe deflection and long service life.
X-TEND stainless steel cable mesh opens up a whole new world of spatial possibilities using cables. The intelligent combination of stainless steel cables and ferrules is the key to a range of shapes for engineered cable mesh constructions. The opposing curvature of the cables permits light, transparent structures possessing extremely high load capacity and long spans due to the low weight of the X-TEND material.
Architecture with X-TEND stainless steel cable mesh is transparent and innovative. X-TEND stainless steel cable mesh can be used in all kinds of applications including balustrades on bridges and staircases, flexible zoo enclosures, large barrier fences, and building façade trellis systems.
X-TEND stainless steel cable mesh offers various possibilities for use in architecture and interior design. Different diameters and flexible mesh sizes allow tailor-made solutions, from safety structures, stairways, walkways and platforms through zoo enclosures and greeneries up to three-dimensional structures.

Detail #2 – Material selection detail that blocks hidden corrosion
Choosing between AISI 304 and AISI 316 stainless steel is not cosmetic: 316 with molybdenum is strongly recommended for marine and offshore atmospheres to resist pitting and crevice corrosion from salt spray. Under-specified grades can look fine during installation yet start to stain, crack and fail years earlier, raising unexpected replacement costs.
Description of 316 Flexible Stainless Steel Mesh Netting Balustrade for Marinas
Our 316 Flexible Stainless Steel Mesh Netting balustrade for marinas uses marine-grade wire rope, precision hand-woven stainless steel cable mesh into an elastic yet strong barrier. It is designed to handle constant moisture, spray, and mechanical loads from crowds, trolleys and equipment without stretching out of shape.

Risk #3 – Balustrade risk that exposes marinas to claims
If balustrade mesh at marinas is under-rated for crowd loading or impacts from trolleys and cargo, deformation and gaps can appear. This creates a clear risk of falls and legal liability. Choosing a certified mesh aperture and wire diameter combination – like the BMP series above – closes this risk and keeps the marina visually open yet reliably secure.

Benefit #4 – Load capacity benefit that protects aircraft and crew
Correctly matched wire rope diameter and mesh aperture deliver high nominal breaking loads with controlled deflection during rotor wash and emergency landings. This benefit directly protects aircraft and crew from overshoot, sliding and edge failures on exposed helidecks.

Problem #5 – Balustrade spacing problem that creates child-climb hazards
If the mesh aperture and angle are not tuned to your local code, children can climb or squeeze through gaps. This problem is eliminated when you match the correct Flexible Stainless Steel Mesh Netting specification to the required infill zone and height.

Trap #6 – Aperture trap that lets animals injure themselves
In zoo and aviary projects, poorly chosen mesh apertures create a trap where animals can get feet, claws or beaks caught. Our zoo and façade specifications avoid this by matching aperture and rope diameter to the species and enclosure geometry.
Performance on Helidecks and Offshore Platforms
Stainless steel helideck safety cable net features:
1. Flexible, elegant, multifunctional, stainless steel wire rope mesh adapts to any geometry.
2. Corrosion resistant, impact resistance, most suitable for the marine environment, can be used more than 30 years.
3. Stainless steel railing mesh is very easy to install and disassemble; it is green and can be reused.
4. Durable structure and high strength provide efficient protection.
5. Maintenance free and easy to clean.
Cost #7 – Lifecycle cost point that punishes cheap alternatives
Galvanized or non-marine meshes can look cheaper on day one, but when you add repainting, replacement, shutdowns and inspection findings, the lifecycle cost quickly exceeds a properly specified Flexible Stainless Steel Mesh Netting system in AISI 316.
Stainless steel helideck mesh applications:
Helipad safety net
Helideck perimeter mesh
Security netting
Deck mesh and so on
Advantage #8 – Safety advantage that improves audits and approvals
Helidecks equipped with tested Flexible Stainless Steel Mesh Netting achieve smoother safety audits and easier approvals from aviation and maritime authorities. This advantage reduces project delays and protects your company’s reputation.
Installation, Tensioning and Maintenance
Correct installation is as critical as the mesh itself. Cable terminations, edge plates, tension rings and support structures must all be designed for the same loads and environmental conditions as the mesh.
Warning #9 – Installation warning that can trigger sudden failure if you ignore it
If installers under-tension the mesh, use incorrect clamps, or mix dissimilar metals without isolation, you create a hidden weak point. Especially Warning #9 – if you do not follow it carefully, you risk sudden mesh loosening, local tearing and serious loss from falls, aircraft damage or dropped objects.
Routine rinsing with fresh water in marine environments and periodic visual inspection of ferrules, edge cables and supports are usually sufficient to keep the system performing for decades.
Payoff #10 – Long-term payoff that rewards correct specification
When you choose the right Flexible Stainless Steel Mesh Netting specifications, materials and installation methods from the start, the payoff is a high-transparency, low-maintenance safety system that protects people and assets year after year, while keeping your deck, marina or zoo visually open and modern.
