About product

Our marine rectangular window frames are typically manufactured from high-quality carbon steel, stainless steel, or aluminum alloy. Depending on the application environment, they can be treated with anti-corrosion coating or anodizing to ensure durability in harsh marine conditions with high salt spray and strong corrosion.

Glass Types:

  • General Series (N): Equipped with tempered safety glass, with the frosted side facing outward. It offers high strength and safety.
  • Fireproof Series (P): Fitted with fire-resistant glass, effectively blocking flames and high temperatures.
  • Heating Series (H): Uses electrically heated glass to prevent icing or fogging, ensuring clear visibility in cold or humid environments.

Product Detail

Standard Marine Rectangular Windows

Marine rectangular windows (also known as square windows) are widely used in deckhouses or superstructures above the freeboard deck. They not only provide natural lighting, ventilation, and visibility but also enhance the overall aesthetics of the vessel. With a well-designed structure, these windows rely on rubber sealing strips and bolt compression to achieve wind and rain resistance. However, compared with portholes, their watertight performance is relatively weaker, making them more suitable for non-watertight compartments and superstructures.

Our main window frame and sash frame are made from corrosion-resistant metals such as carbon steel, copper alloy, or aluminum alloy. Welded frames are usually constructed from carbon steel, providing higher strength and reliability.
