Laboratory Steel Stairs for Corrosion-Resistant Access

t384-30

Laboratory steel stairs are custom staircase structures built from steel with corrosion-resistant finishes, designed for access to plant rooms, roofs, mezzanines and equipment areas where regular cleaning and chemical exposure are routine. They are fabricated to measure, so the treads, landings and railings suit the room layout and the surfaces can be cleaned without crevices that trap contaminants.

Why laboratories need a different kind of stair

A laboratory or clean room is not a typical building interior. Staircases may be exposed to cleaning agents, humidity, washdown routines and occasional spills, and they must remain stable and easy to inspect over many years. Standard off-the-shelf stairs often leave gaps, sharp corners and hard-to-clean joints that create problems for hygiene teams.

Choosing a steel structure designed for these conditions from the start avoids costly replacements later.

Choosing the right steel and finish

The finish matters as much as the steel itself. Hot-dip galvanizing gives strong protection for structural members, while powder coating adds a smooth, cleanable surface in the colors your facility requires. Stainless steel is an option for components that face the most aggressive cleaning or chemical contact.

Powder-coated surfaces for smooth, easy-wipe finishing
Stainless steel parts where exposure is most severe

Designing for cleanability

Clean rooms favor surfaces without ledges, pockets or open seams where dust and residue can settle. Welded joints should be ground smooth and edges rounded, and the design should leave enough clearance for mopping and inspection beneath the treads. Closed profiles are preferable to open channels where possible.

Discuss the cleaning routine with us before the drawing stage so the details match how your team actually works.

Safety, railings and code compliance

Stairs in technical facilities must be safe for staff who carry equipment and often wear protective gear. Handrail height, guard design and step dimensions should follow the applicable Israeli railing standard SI 1142, and the exact values are verified with your engineer during the design phase. Non-slip tread surfaces are important where floors may become wet.

Our work process from inquiry to installation

The process begins with an inquiry and photos of the space. We then measure on site, prepare a drawing and a written specification, and wait for your approval before production starts. Fabrication takes place in our factory on Rival Street in Tel Aviv, followed by finishing and installation at your site.

Planning installation around a working lab

Laboratories rarely stop operating for construction, so installation timing matters. We recommend planning the stair delivery with your facilities team, protecting nearby equipment, and scheduling the work in phases where needed. Clear communication before installation day keeps disruption to a minimum.

Frequently asked questions

Are steel stairs suitable for clean rooms?

Yes, when designed with smooth, closed surfaces and a corrosion-resistant finish. The layout should allow easy cleaning and inspection of all surfaces.

What finish is best for corrosion resistance?

Hot-dip galvanizing protects the structure, and powder coating or stainless steel parts add a cleanable surface. The right choice depends on your cleaning chemicals and exposure level.

Can the stairs be made to fit an existing room?

Yes. Every staircase is fabricated to measure after an on-site survey, so it fits the available space and access requirements.

Do you check railing and step dimensions against standards?

Yes, we follow the general requirements of Israeli standard SI 1142, and exact values are confirmed with your engineer during design.

Common mistakes to avoid

A common mistake is ordering stairs before considering cleaning access, which leaves hidden corners that trap contamination. Another is choosing an unsuitable finish that corrodes under routine chemical washdown.

Our recommendation

Ask for the cleaning routine and chemicals used in the space before design begins, and request a finish recommendation based on that information. Confirm railing and step details with your engineer before approving the drawing.

Summary

Laboratory steel stairs need corrosion-resistant finishes, cleanable details and measured fabrication to suit demanding environments. A careful design and approval process prevents problems after installation.
