Ship deck material selection guide: 5052 5083 6061 3003 Tread Checkered Aluminum Plate

In ship deck design, tread checkered aluminum plate has become the mainstream choice due to its lightweight, corrosion resistance, and high anti-slip properties. The performance differences of different alloy models directly affect the service life, safety and economy of the deck. This article will show you the advantages and disadvantages of 5052 5083 6061 3003 Tread Checkered aluminum plates, helping you quickly match the best solution.

5052 5083 6061 3003 tread checkered aluminum plate for ship deck

• 1. 5052 tread checkered aluminum plate

Application scenarios: conventional areas of the main deck (crew operation area, cargo aisle); decks of small and medium-sized ships (cost and corrosion resistance must be taken into account).

✅ ‌Advantages‌:

Strong resistance to seawater corrosion (magnesium content 2.5%), suitable for long-term humid environment.

Excellent processing performance, easy welding and bending, suitable for complex deck structures.

High cost performance, the overall cost is lower than 5083 tread checkered aluminum plate and 6061 tread checkered aluminum plate.

✅ Disadvantages‌:

Medium strength (tensile strength 230-280MPa), not suitable for extremely high load areas.

• ‌ 2. 5083 tread checkered aluminum plate

‌Application scenarios‌: large cargo ships, main decks of ocean-going ships; high load areas (such as heavy machinery operation areas, helicopter landing platforms).

✅ ‌Advantages‌:

High strength (tensile strength 270-320MPa), certified by classification societies, excellent impact resistance.

Excellent corrosion resistance (magnesium content 4.5%), 20 years maintenance-free.

✅ Disadvantages‌:

The cost is 15%-20% higher than 5052 tread checkered aluminum plate, and special equipment is required for processing.

• ‌ 3. 6061 tread checkered aluminum plate‌

‌Application scenarios‌: decks in high-corrosion environments (chemical ships, tanker operation areas); suspended decks, low-temperature cold chain cabins (resistant to low temperatures to -50°C).

✅ ‌Advantages‌:

The strongest resistance to chemical corrosion (acid and alkali resistance increased by 200% after anodizing).

Highest strength (tensile strength 300-380MPa), wide range of thickness options (8-20mm).

✅ Disadvantages‌:

The cost is twice that of 5052 tread checkered aluminum plate, and the welding process is complicated.

• ‌ 4. 3003 tread checkered aluminum plate‌

‌Application scenarios‌: temporary decks, secondary pedestrian walkways; small inland ships (low-corrosion environment).

✅ Advantages‌:

The lowest cost, light weight, and easy processing.

‌✅ Disadvantages‌:

Poor corrosion resistance (no magnesium element), regular anti-rust coating is required.

Low strength (tensile strength 110-200MPa), non-load-bearing.

Application and selection recommendations

✅ Prioritize corrosion resistance and strength:

Ocean-going ships: 5083 (H321 ship classification certification) is a must, the first choice for safety in extreme environments.

Chemical ship decks: 6061+anodized treatment, acid and alkali resistance life increased by 3 times.

✅ Balance cost and performance:

Small and medium-sized ships: 5052 has the best cost-effectiveness, covering 90% of conventional needs.

Temporary decks: 3003 can be replaced in the short term, but regular maintenance is required.

✅ Special process requirements:

When custom patterns are required (such as encrypted anti-skid ribs), 5052 or 5083 is preferred, which has stronger processing compatibility.

No matter which tread checkered aluminum plate is selected, please pay attention to the following points:

◆ Anti-skid treatment: Five ribs or compass pattern design is preferred, and the friction coefficient is increased by 30%-50%.

◆ Thickness Matching‌: 3-8mm is recommended for conventional decks, and 8-12mm is required for high-load areas.

◆ ‌Surface Process‌: Anodizing or spraying is used to enhance wear resistance and UV resistance.
