Aluminum Boat Trims

Aluminum boat trims are primarily used for the external decoration and protection of the boat hull. These aluminum alloy profiles provide an aesthetic and corrosion-resistant decorative effect, typically applied around the edges of the hull, hatches, and deck areas. Due to the lightweight and durable characteristics of aluminum alloys, they effectively prevent seawater corrosion, ensuring the boat's appearance and performance over long-term use.

Aluminum Boat Handrails

Aluminum boat handrails provide safety and stability, helping crew members and passengers maintain balance and walk on board. Boat handrails are typically installed in areas such as the cabin, deck, or stairs. The aluminum alloy material gives the handrails high strength and corrosion resistance, while being lightweight, easy to install, and maintain.

Boat Trailers and Ladders

Boat trailers are used for transporting and storing boats, and they are usually made of aluminum alloy profiles to ensure structural strength and durability. The corrosion resistance of aluminum guarantees the trailer's longevity in humid environments. Boat ladders are used to help people board and disembark from the boat. Aluminum boat ladders are not only lightweight but also corrosion-resistant, ensuring long-term use in seawater environments.

Boat Gratings and Deck Houses

Boat gratings are typically used for drainage and ventilation on decks and other areas. Aluminum alloy gratings have excellent corrosion resistance and can withstand the vibrations and wear of the boat during navigation. Deck houses, as additional structures on the boat, are typically built using aluminum alloy profiles, offering waterproof, corrosion-resistant, and wind-resistant properties, providing comfortable space and protection.

Boat Windscreen Frames

Aluminum boat windscreen frames are used to support the boat’s windows and doors, protecting crew members from wind and seawater. The aluminum alloy frames not only provide strength and rigidity but also perform excellently in marine environments due to their corrosion resistance. Their lightweight design helps reduce the boat’s overall weight and improve its performance.
