The support column forms the structural foundation of the Gangway Tower, designed for stability and durability. Fabricated from high-strength GB-Q235 and GB-Q345B steel, it complies with standards like the AISC Manual of Steel Construction and GB/T 8162 for structural purposes.

Featuring stairways, anti-slip platforms, and safety handrails, it ensures safe operator access. Optional features include firewater monitors or hydraulic cranes. The column is electrically isolated from the jetty platform, with corrosion-resistant coatings to withstand marine exposure. Mechanical devices secure the gangway in its stowed position, ensuring stability even in extreme conditions
