Planning Staircase Landings in Steel Structures

t390-8

Staircase landing planning in steel structures means fixing the landing height, depth and position before any steel is cut, so the flights, supports and guardrails fit the building exactly. Good planning starts with accurate on-site measurement, continues with a written drawing that the client approves, and ends with a landing built in the factory and fitted on site.

Why the landing comes first in the plan

In a multi-level home, the landing is the point where two flights meet and where the stair changes direction. Its size and height decide how the rest of the staircase works. If the landing is planned late, the flights often end up too steep, too short or misaligned with the floor opening above.

Designers planning a steel staircase should define the landing level, the available depth and the clear width before choosing the flight design. This keeps the structure honest with the architecture from the start.

Measuring the space on site

Measurements should be taken on site, not only from the architectural plan, because walls, slabs and openings often differ from the drawings. Check the floor-to-floor height, the opening size, the wall positions and any beams or ducts that cross the stair path.

Floor-to-floor height at both levels
Clear width between walls or balusters
Landing depth and any obstructions
Position of doors and windows nearby

Drawing and written specification

After measuring, the workshop prepares a drawing showing the flights, the landing, the supports and the guardrail line. A written specification accompanies it, listing materials, profile sizes, finishes and how the landing connects to the structure.

Exact safety values such as guardrail heights and gaps should be confirmed with the project engineer, with reference to the Israeli railing standard SI 1142. The client approves the drawing in writing before production begins.

Production in the factory

Once the drawing is approved, the steel landing frame, stringers and treads are cut, welded and checked in the factory. Working in the workshop allows precise tolerances and makes it easier to test the assembly before it leaves for site.

Finishing follows production. Hot-dip galvanizing or powder coating protects the steel, and the chosen finish should be agreed at the approval stage so there are no surprises on delivery.

Installation and fitting on site

Installation begins with setting the landing supports at the planned level, checking them with a level and fixing them to the structure as specified by the engineer. The flights are then attached to the landing and the guardrails are fitted.

Confirm supports are level and secure
Check flight alignment before final fixing
Test the handrail and guardrail for firmness

Checking the finished landing

After installation, check that the landing is level, the treads are even, the handrail is comfortable to grip and the gaps meet the approved drawing. Small adjustments are easier to make at this stage than after the finishes are applied around the stair.

Keep the approved drawing and specification with the project documents so future work on the building can refer to the exact landing details.

Frequently asked questions

How early should the landing be planned?

Plan the landing before the flights and before the floor opening is finalized. Changing the landing late usually forces changes to the whole staircase.

Should measurements be taken from the plan or on site?

Always measure on site, because real walls and slabs often differ from the architectural drawings. Use site measurements to prepare the final drawing.

Who checks the safety values of the landing?

Safety values such as guardrail heights should be confirmed with the project engineer. The workshop can reference the Israeli standard SI 1142 during design.

Can the landing finish be changed after production?

It is best to agree the finish at the approval stage. Changing it after galvanizing or powder coating is production work and should be planned in advance.

Common mistakes to avoid

The most common mistake is planning the landing from the architectural plan alone without site measurements. Another is approving the drawing without confirming the finish and guardrail details.

Our recommendation

Before approving the drawing, walk the stair path with the designer and check headroom, landing depth and handrail position with a tape at the real height. Confirm the finish and safety details in writing.

Summary

Good staircase landing planning in steel starts with accurate site measurement, a clear approved drawing and factory production that is checked before installation.
