Non slip aluminium sheet are widely used on yachts, mainly in decks, passages, stairs, gangways, operating platforms and equipment bases, aiming to improve anti-skid performance and ensure personnel safety, especially in humid or salt spray environments.

Non slip aluminum plates for yachts are usually made of aluminum alloys with excellent corrosion resistance and moderate strength. Common grades include:

1. 5083 aluminum alloy

- It belongs to the Al-Mg alloy series (magnesium content is about 4.0-4.9%) and is a classic material for shipbuilding.

- Advantages: It has strong resistance to seawater corrosion, excellent weldability, good low-temperature toughness, and is suitable for decks, ship sides and other parts that are in long-term contact with seawater.

2. 5052 aluminum alloy

- It contains about 2.2-2.8% magnesium, and its strength is slightly lower than 5083 aluminum, but its formability is better.

- Advantages: It is light in weight and resistant to salt spray corrosion. It is suitable for anti-skid parts of yacht decks or interior decorations that require higher lightweight.

The tamper of anti-slip aluminum plate needs to take into account strength, corrosion resistance and processability. Common tempers include:

1. H112 temper

- Suitable for aluminum tread plates that have not been annealed or cold-processed after hot processing (such as rolling, extrusion), retaining the natural corrosion resistance of the material, moderate strength, and stable performance after welding. It is the mainstream choice for yacht anti-skid plates.

2. H32 temper

- After cold processing, it is incompletely annealed (stabilization treatment), with slightly higher strength than H112, moderate hardness, and good surface flatness. It is suitable for scenes with high requirements for anti-slip pattern forming accuracy.

Thickness and width of non slip aluminium sheet using in yacht:

1. Thickness

- Conventional range: 2-8mm, specifically adjusted according to the load-bearing requirements and lightweight design of the yacht deck:

- Small yacht or interior anti-slip strips: 2-4mm;

- Large yacht main deck: 4-8mm, taking into account strength and impact resistance.

2. Width

- Standard board width: 1000-2000mm, can be customized according to the size of the yacht deck, reduce joints, improve aesthetics and sealing.

The design of anti-slip pattern needs to take into account friction, drainage and aesthetics. Common types include:

1. Five-bar pattern (most classic)

- The pattern is five longitudinal ribs with uniform spacing and rib height of 0.5-1.5mm. The surface friction coefficient is high, and the accumulated water can be quickly discharged along the rib groove. It is suitable for slippery areas such as the main deck and gangway.

2. Diamond/honeycomb pattern

- The pattern is grid-shaped, with a large contact area and uniform anti-slip effect. It is suitable for deck areas that need to take into account aesthetics (such as leisure areas and cockpits). Some designs can be embedded with anti-slip particles to enhance friction.

3. Customized pattern

- According to the design requirements of the yacht, pointer-type, corrugated-type or brand-identification patterns can be processed to meet functional and personalized needs.

Performance requirements of non slip aluminum sheet using in yachts:

1. Corrosion resistance

- It must pass the salt spray test (such as ASTM B117, no obvious corrosion for more than 500 hours), resist erosion by seawater and humid air, and avoid surface oxidation affecting anti-slip performance.

2. Mechanical properties

- Taking 5083-H112 as an example: tensile strength: ≥270MPa, yield strength: ≥110MPa, elongation: ≥12%, meeting the deck load-bearing and impact resistance requirements.

3. Anti-slip

- Dry friction coefficient: ≥0.6, wet friction coefficient: ≥0.4 (GB/T 20973 test standard), ensuring the safety of personnel walking in a humid environment.

4. Lightweight and weather resistance

- The density is about 2.7g/cm³, which is only 1/3 of that of steel, reducing the weight of the yacht; it is resistant to UV aging and will not fade or crack after long-term outdoor use.

Application advantages of non slip aluminium sheet using in yacht:

1. Excellent seawater corrosion resistance

- A dense oxide film is naturally formed on the surface of 5000 series aluminum alloy, which does not require frequent maintenance and has a service life of more than 20 years, far superior to ordinary steel or non-corrosion-resistant alloys.

2. Balance of lightness and strength

- Reduce the overall weight of the yacht, improve fuel efficiency and sailing speed, and meet the strength requirements of the deck for rolling resistance and collision resistance.

3. Safe, non-slip and easy to clean

- The pattern design effectively prevents people from slipping, especially suitable for slippery scenes such as yachts docking and windy weather; the surface is smooth and easy to wash, and it is not easy to accumulate dirt in seawater residue.

4. Convenient processing and installation

- It can be flexibly processed by shearing, bending, and welding (such as TIG welding) to adapt to the complex curved surface of the yacht; the plate can be directly laid or fixed by bolts, and the installation efficiency is high.

5. Beautiful and environmentally friendly

- The pattern enhances the appearance and texture of the yacht; the aluminum alloy can be 100% recycled, which is in line with the trend of green shipbuilding.

Non slip aluminium sheet using in yacht is based on 5000 series aluminum alloy. By optimizing the alloy composition, state and pattern design, it achieves a balance between corrosion resistance, lightness and safety. It is the first choice for modern yacht deck materials. In practical applications, it is necessary to customize appropriate specifications and surface treatment processes according to the type of yacht (sailboat/powerboat), use environment (nearshore/ocean) and design requirements to maximize the advantages of the material.
