Stair Tread For Marine Ladder

The significant advantage of bar grating stair treads is their ability to prevent water accumulation. The open grid pattern of the floor grates allows water to pass through, reducing the risk of water pooling on the stairs. This feature is particularly important in marine environments where water exposure is common. By preventing water accumulation, the floor grates enhance safety by minimizing the chances of slip and fall accidents.

Choose The Right Marine Stair Tread

When selecting the right marine stair tread for ladders used on boats and ships, it’s crucial to consider the unique challenges posed by the marine environment. The chosen material should be durable, corrosion-resistant, and provide excellent slip resistance. Here are two commonly used options:

  • Stainless Steel Stair Treads: Stainless steel is a popular choice for marine applications due to its exceptional corrosion resistance. Stainless steel stair treads offer durability and can withstand the harsh marine environment effectively. In addition, they are easy to clean and maintain, making them a practical choice for marine ladder treads.
  • Non-Slip Coatings: To ensure safety in wet conditions, it is essential to apply non-slip coatings to ladder treads. These coatings can be made from materials such as rubber, epoxy, or polyurethane. They provide enhanced traction, preventing slips and falls. Non-slip coatings are an effective way to improve safety on marine ladders.


Four Types Of Bar Grating Stair Tread

  • Type: ZT1
    Front guard: No front guard
    Installation mode: WeldedIn this type of bar grating stair tread, there is no front guard provided. The stair tread is welded to the supporting structure, ensuring a secure and permanent installation.
  • Type: ZTF2
    Front guard: No front guard
    Installation mode: BoltingSimilar to ZT1, this type also does not have a front guard. However, instead of welding, the stair tread is installed using a bolting mechanism. This allows for easier removal and replacement if needed.
  • Type: ZT3
    Front guard: Patterned front guard
    Installation mode: WeldedZT3 features a patterned front guard, which provides additional safety by preventing objects from falling through the front of the bar gstair tread. The tread is welded to the supporting structure for a sturdy and durable installation.
  • Type: ZT4
    Front guard: Patterned front guard
    Installation mode: BoltingSimilar to ZT3, this type includes a patterned front guard for increased safety. The main difference is the installation mode, which involves bolting rather than welding. This allows for easier installation and removal compared to welded bar grating stair treads.
