Upgrading a Staircase with Steel Stringers and Treads

t391-2

A steel stringer staircase upgrade replaces or reinforces the side supports and steps of an existing staircase with custom-made steel, giving a stronger, cleaner and more durable result. It is usually done by measuring the current stair, designing a new steel structure that fits the existing openings, and installing it with matching treads and railings.

When an Existing Staircase Needs an Upgrade

Many older staircases show their age through sagging steps, creaking treads, rust at the joints, or a look that no longer suits the home. Some owners also want to improve safety or open up a tight space. A steel stringer upgrade can address these issues without rebuilding the whole house.

Why Steel Stringers Are a Strong Choice

Steel stringers are the side beams that carry the treads. Because steel is strong for its thickness, stringers can be slimmer than many alternatives while still carrying the load safely. This leaves more room on the stairs and gives a clean, airy line. When properly finished, steel also resists wear well over many years.

Each stringer is shaped to the specific rise, run and angle of the staircase, so the result suits your space rather than a generic layout.

Planning the Upgrade: Measurement and Design

Accurate measurement is the foundation of a good upgrade. Our team visits the site and records the height, width, step dimensions and the condition of the existing structure, including the walls or floor where the stringers will be fixed. Photos and notes help us plan the work before anything is cut.

From these measurements we prepare a drawing and a written specification. You review and approve it before production starts, so you know exactly what will be built.

Choosing Treads, Finishes and Railings

Steel stringers can be paired with different tread materials, such as steel, wood or other finishes, depending on your taste and the use of the stair. The steel parts are typically hot-dip galvanized for corrosion protection and can be powder coated in the colour you choose.

Railings should be planned together with the stringers. Handrail and guard heights must meet safety requirements, and the Israeli railing standard SI 1142 is a useful reference. Exact values should always be confirmed with your engineer during design.

Production and Installation Steps

Once the design is approved, the steel parts are manufactured in our workshop at 37 Rival Street, Tel Aviv. Cutting, welding and finishing take place in the factory, which helps keep the quality consistent. Finished components are then delivered and installed on site.

Keeping the Staircase Safe and Looking Good

After installation, a little regular care keeps the staircase in good shape. Wipe down coated surfaces, check fixings from time to time, and look for any loose treads or railings. Prompt attention to small issues prevents larger repairs later.

If you notice new movement, scratches in the finish or any change in the structure, contact us so we can inspect it.

Frequently asked questions

Can steel stringers be fitted to my existing staircase?

In many cases yes, because the new stringers are built to the measurements of your current stair. Our on-site visit confirms whether the existing structure and walls can support the new steel.

Is a steel staircase safe for a home?

Yes, when it is designed and installed correctly with suitable railings and finishes. Safety dimensions should always be confirmed with a qualified engineer.

Do steel stairs need special maintenance?

They need only simple care such as cleaning and occasional checks of fixings and coatings. Galvanizing and powder coating help protect them against corrosion.

How do I start the upgrade process?

Begin by sending us photos of your staircase and a short description of what you want to change. We will then arrange an on-site measurement and prepare a drawing for your approval.

Common mistakes to avoid

A common mistake is ordering before the staircase has been measured on site, which can lead to fit problems. Another is choosing finishes and railings separately from the stringers, causing mismatched heights and styles.

Our recommendation

Measure and photograph the current staircase carefully, and decide on railings and finishes at the same time as the stringers so the whole staircase is designed as one piece.

Summary

Upgrading a staircase with steel stringers and treads gives a stronger, cleaner and longer-lasting result when it is planned from accurate measurements.
