Steel Emergency Stairs for Shared Buildings: A Practical Guide

t382-17

Steel emergency stairs are a common choice for shared buildings because they are durable, non-combustible and can be fabricated to fit tight external spaces. For a reliable fire egress route, the stair must be designed with correct widths, landings, handrails and fixings, and approved by the responsible engineer before production begins.

Why Steel Suits Shared Building Egress Routes

Shared residential and commercial buildings often need an external escape route that is used daily by many people and must perform reliably in an emergency. Steel is a practical material for this purpose. It is strong, non-combustible and keeps its structural integrity over many years of use, which makes it suitable for exterior stairs exposed to weather and foot traffic.

Steel also allows the stair to be built as a compact, self-supporting structure that attaches to an existing wall or balcony line. This matters in buildings where space is limited and a conventional concrete stair is not an option.

Key Design Points for Building Managers

Before any fabrication starts, the stair should be reviewed against the requirements of the building's fire safety plan. The points below are the ones managers most often need to confirm with the design engineer:

Clear width of the stair and landings
Rise and tread geometry for safe, consistent steps
Landing sizes at the top, bottom and turns
Handrail height and continuity
Connection points to the building and load paths

Exact values depend on the building and the applicable code, so they should be checked with the engineer rather than assumed.

Handrails, Guards and Safety Details

Handrails and guards are central to both safety and code compliance. Israeli railing requirements are set out in standard SI 1142, and the engineer will confirm the exact dimensions for your project. Pay attention to grip comfort, the spacing of balusters so that a small child cannot pass through, and anti-slip treatment on treads.

Details worth confirming early

Ask whether the stair includes continuous handrails on both sides, whether intermediate landings are provided, and how the stair meets the door or balcony it serves. These transitions are where users most often hesitate in an emergency.

Materials and Finishing for Exterior Exposure

An external emergency stair lives outdoors, so corrosion protection is essential. Hot-dip galvanizing gives strong long-term protection for the steel, and powder coating adds a durable, good-looking finish in the colour the building requires. Together they reduce maintenance and help the stair remain safe and presentable for years.

Consider how water drains off treads and landings, since standing water becomes a slipping hazard in winter. Anti-slip surfaces and proper drainage are simple details that make a real difference in daily use.

Our Work Process, Step by Step

We begin with an inquiry, where you share photos and a description of the building and the space available. Next, our team visits the site to take measurements. Based on these, we prepare a drawing and a written specification that you review and approve.

Coordinating with Engineers, Architects and the Committee

Shared buildings usually involve several parties: the building committee, the contractor, an architect and sometimes a structural engineer. Clear communication avoids costly changes later. We recommend agreeing on the drawing and specification in writing, with sign-off from the people responsible for fire safety, before any material is cut.

Keep a record of approvals and drawings for the building file. This documentation helps during inspections and makes future maintenance or modifications much simpler.

Frequently asked questions

Can a steel stair be used as a fire egress route?

Yes, a properly designed steel stair can serve as part of a fire egress route. It must meet the building's fire safety requirements, which should be confirmed by the responsible engineer.

What handrail standard applies in Israel?

Israeli railing requirements are set out in standard SI 1142. The exact dimensions for your project should be checked with the engineer.

How is steel protected against weather?

Hot-dip galvanizing provides long-term corrosion protection, and powder coating adds a durable finish. Together they suit exterior exposure.

Who should approve the stair design?

The design should be approved by the building committee and the responsible engineer or architect, with fire safety requirements confirmed before production begins.

Common mistakes to avoid

A common mistake is ordering a stair based on appearance alone, without checking widths, landings and handrail continuity against the fire safety plan. Another is skipping written approval before fabrication, which can lead to expensive changes later.

Our recommendation

Involve the engineer or architect at the start, not after the stair is built, and get the drawing and specification approved in writing. Confirm handrail, landing and anti-slip details early, since these are the elements most often overlooked.

Summary

Steel emergency stairs can serve shared buildings well when they are designed, approved and installed with fire egress requirements in mind.
