Steel Stairs for Ship and Marine Dock Access

t384-24

Steel stairs provide safe, durable boarding access between a marina dock and a vessel, and marine steel gangway stairs are typically built to measure with galvanized or stainless steel to resist salt air. Each staircase is designed around the height difference, the boat's freeboard and the expected traffic on the dock.

Why Steel Suits Marina Boarding Access

Docks and marinas expose metal to salt spray, humidity and constant movement. Steel that is properly finished handles this environment far better than bare or lightly painted metal. A well-built steel staircase gives boat owners and crew a stable, predictable step that stays put in all weather and does not warp under daily use.

Steel also allows slim, open structures that keep the walkway clear and let water drain through, which matters on wet decks.

Measuring the Height Difference Between Dock and Deck

Accurate boarding access starts with measurement. The height between the dock surface and the boat's deck changes with tide, load and the vessel's freeboard, so the staircase must be planned around a realistic range rather than a single moment. We recommend measuring at low and high water if the marina has significant tidal movement, and noting how the boat sits when fully loaded with people and gear.

Choosing Materials and Finish for Salt Air

For marine use, hot-dip galvanizing is a common choice for structural steel because the zinc coating protects the base metal even where it is scratched. Powder coating adds a colored, smooth layer on top. Stainless steel is another option, particularly for railings and fittings that users touch often. The right combination depends on how exposed the dock is and how much maintenance the marina wants to schedule.

Designing for Safety and Non-Slip Use

A boarding staircase should have treads that give grip when wet, sturdy handrails on both sides where space allows, and a rise and tread depth that feel comfortable for people carrying bags or equipment. Handrail and guard requirements in Israel fall under the SI 1142 standard, and the exact dimensions are confirmed with the engineer for each project rather than assumed.

Fitting the Staircase to the Dock Structure

The staircase has to bear on a secure point, whether that is a concrete dock, a steel frame or a pontoon edge. The connection should allow for small movements without loosening, and the top landing should be stable enough to step onto from a moving boat. Fixings should be chosen for marine conditions, with stainless or galvanized hardware, to avoid corrosion at the joints.

Our Process from Inquiry to Installation

Every marine staircase starts with photos and a description of the dock and vessel. We then take the on-site measurements, prepare a drawing and a written specification, and send it for your approval. After approval the staircase is manufactured in our Tel Aviv workshop, finished with the chosen galvanizing or coating, and installed at the marina.

Frequently asked questions

Should marine staircases be galvanized or stainless steel?

Galvanized steel is a strong, cost-effective choice for structural parts, while stainless steel suits railings and fittings that get frequent contact. Many marinas use both together. We recommend the mix based on exposure and maintenance expectations.

Can the staircase adjust for tidal changes?

A staircase can be designed around the full range of water levels, with a top landing and angle suited to the tidal difference. Measuring at both low and high water helps us plan for the actual range at your marina.

How do you protect steel from salt water corrosion?

We use hot-dip galvanizing and powder coating on suitable parts, and select stainless hardware for joints and fixings. The exact finish is matched to how exposed the dock is.

Do you install the staircase as well as manufacture it?

Yes, the process includes installation after the staircase is made in our Tel Aviv factory and approved by you. Installation details are agreed in the written specification.

Common mistakes to avoid

Planning the staircase for one water level only, and using plain untreated steel or unsuitable fixings that corrode quickly in salt air.

Our recommendation

Measure the boarding height at both low and high tide and confirm the freeboard of the largest boat that uses the dock. Specify galvanized structure with stainless fittings from the start, since changing the finish later costs more.

Summary

Well-designed marine steel gangway stairs give safe, durable boarding access when they are measured for the real tidal range and finished for salt air.
