Category

About product

Marine steel vertical ladders are essential safety access equipment for ship compartments, decks, and vertical passageways. Their inclination angle is strictly controlled within the range of 80°–90°, ensuring reliable vertical access in limited spaces.These vertical ladders are widely used in engine rooms, cargo holds, living areas, and decks, and can be customized according to compartment height and installation requirements to meet the safety access needs of different vessel types.

  • Our ship ladders are manufactured from high-quality carbon steel or stainless steel and treated with hot-dip galvanizing or anti-corrosion coating for superior strength, durability, and long service life.
  • The steps are designed with anti-slip patterns or strips to enhance climbing safety, while sturdy handrails on both sides provide additional support for operators.

Product Detail

Marine Steel Vertical Ladder

Our marine steel vertical ladder is a safety access device specially designed for ships. It is commonly installed in compartments, bulkhead passages, masts, derrick posts, and deckhouses, but is not suitable for cargo holds or oil tanks. With a rational structure and reliable strength, it provides crew members with a safe and convenient means of vertical access.

Fixed Vertical Ladder: Permanently installed on the ship’s bulkhead or deck by welding or bolting. The structure is stable and durable, making it suitable for long-term use with low maintenance costs.

Detachable Vertical Ladder: Designed with a modular structure for easy transport and installation. Connected with bolts for quick assembly and disassembly, it is ideal for temporary inspection passages or emergency escape needs, offering higher flexibility.
