Metal Staircase Planning Process: From Floor Plan to Install

t502-35

A metal staircase is planned in stages: the architect's floor plan is checked, the openings are measured on site, detailed drawings and a written specification are approved, then the steel is produced and finished in the factory before installation. Following this order prevents dimensional errors and rework.

Starting From the Architect's Floor Plan

The process begins with the floor plan and sections provided by the architect or interior designer. We review the stair type, rise and going, landing positions, ceiling heights and the structure the staircase connects to. Any unclear detail is noted at this stage so it can be resolved before measuring.

Stair type: straight, L-shaped, U-shaped or spiral
Intended finishes and materials
Structural supports and fixing points

A clear brief at this point saves time later and keeps the design intent intact.

On-Site Measurement

Our team visits the building to measure the opening, floor levels and wall conditions. Concrete slabs, tiles and screed can change the final height, so measurements are taken on the finished or near-finished surfaces where possible. We record each dimension and photograph the area for reference.

Measuring on site rather than relying only on drawings is one of the most important steps for accurate fit.

Drawings and Written Specification

Based on the measurements, we prepare shop drawings showing stringers, treads, risers, handrail positions and connection details. A written specification lists materials, profiles, welds, finishing and fixing methods. Railing requirements follow the Israeli standard SI 1142, and exact values are confirmed with the engineer for each project.

The architect reviews and approves the drawings before any steel is cut.

Client Approval and Scheduling

Once the drawings are approved in writing, production is scheduled. Any design change requested after approval is reviewed for its effect on dimensions, fixings and finishing. Clear sign-off at this stage protects both the designer and the fabricator from later disputes.

Production and Finishing in the Factory

At our workshop on Rival Street in Tel Aviv, the steel is cut, shaped, welded and ground to the approved drawings. Components are then prepared for finishing. Depending on the project, we use hot-dip galvanizing or powder coating to protect the steel and achieve the chosen appearance.

Assembling sample parts in the workshop helps catch fit issues before the staircase reaches the site.

Installation and Final Check

On installation day, the stair components are delivered and fixed to the structure according to the approved details. We check levels, alignment, handrail height and the stability of each connection. Any touch-up of finishes is done on site after fixing.

A final inspection with the architect confirms that the staircase matches the design and is ready for use.

Frequently asked questions

How early should the staircase be planned in a building project?

Ideally the staircase is planned during the design phase, once the floor levels and openings are fixed. This allows the metalwork to be coordinated with the structure before concrete work is completed.

Who approves the staircase drawings?

The architect or designer reviews and approves the shop drawings in writing before production begins. This ensures the final product matches the intended design.

Why is on-site measurement necessary if drawings already exist?

Drawings may not reflect the actual finished dimensions of the building. On-site measurement captures real levels and openings, reducing the risk of misfit.

Can the finish be changed after production starts?

Finish choices should be confirmed before production. Changes after that point may affect the schedule, so they should be discussed and approved early.

Common mistakes to avoid

Measuring only from the original drawings and not confirming finished floor levels is a common cause of misfit. Approving drawings without a careful review of handrail heights and fixing points also leads to costly corrections.

Our recommendation

Confirm the finished floor levels and tile thickness before ordering steel, and approve the drawings in writing with the finish colour noted. This single step prevents most installation problems.

Summary

A successful metal staircase follows a clear sequence: floor plan review, on-site measurement, approved drawings, factory production and finishing, then careful installation.
