Open-Riser vs Closed-Riser Stairs: Which Needs Which Railing?

t323-42

A closed-riser staircase has solid vertical boards between treads, while an open-riser staircase leaves gaps between them. Both can use metal stair railings, but open risers usually need extra attention to guarding, infill spacing and fall safety because a person or object can slip through the open space.

What Is the Difference Between Open and Closed Risers?

The riser is the vertical face between one step and the next. In a closed-riser staircase, that face is solid, so each step looks like a continuous block. In an open-riser staircase, the vertical space is left empty, so you can see through the stairs from the side.

Both designs are common in homes and buildings. The choice affects the look of the stair, how light passes through it, how it is cleaned, and how the railing must be planned.

How Each Type Affects Railing Design

A closed-riser stair gives the railing a solid base to fix to, and the infill can be planned mainly around the handrail and posts. With an open riser, the railing and any guard panels often need to continue down to the floor or meet the step edge in a way that blocks gaps.

Closed risers: simpler fixing points, fewer infill concerns
Open risers: more attention to infill, post spacing and the lower edge
Both: handrail height and grip shape must suit daily use

Guard Requirements and Safety Considerations

Guardrails protect people from falling from open edges, and open-riser stairs raise the question of what can pass through the gaps. Children, pets and small objects are the main concerns, so the infill pattern matters as much as the height of the rail.

Israeli railing requirements are set out in standard SI 1142, which should be read with your engineer or local authority. Exact dimensions for height, opening size and load should always be confirmed for your specific project rather than assumed from general rules.

Choosing Infill for Open-Riser Stairs

Common infill choices include vertical bars, horizontal rods, cable systems and glass panels. Vertical bars are traditional and sturdy, and their spacing can be set to limit gaps. Glass gives a clean, open look and lets light through, but it needs proper fixing and sometimes a handrail on top.

Horizontal rods can climb like a ladder for small children, so they are often avoided near open stair edges unless spacing is kept tight. Discuss the household and the view you want before deciding.

Cost, Maintenance and Look

Open-riser stairs can feel lighter and more modern, but they need careful planning of the railing so it meets safety needs without appearing heavy. Closed-riser stairs may be easier to clean on the sides and may suit homes with very young children without extra panels.

Metal stair railings can be hot-dip galvanized or powder coated for outdoor or humid conditions. Maintenance depends on the finish you choose, so ask about it during your inquiry.

Steps to Plan Your Stair Railing

A good plan starts with the staircase itself. Take photos of the stair from several angles, note whether the risers are open or closed, and identify any walls, landings or openings nearby.

Send photos and basic measurements
Arrange an on-site measurement
Review the drawing and written specification
Approve the design before production

This process helps match the railing to the stair type and to the safety requirements that apply.

Frequently asked questions

Do open-riser stairs always need a railing?

Any stair with an open edge or significant height change normally needs a guard and handrail. Whether a specific stair is compliant depends on its layout and should be confirmed with your engineer.

Is glass a good infill for open-riser stairs?

Glass can work well and gives an open look, but it must be properly fixed and suited to the location. Ask for a specification that covers the glass type and its fixing method.

Can I convert a closed-riser stair to open risers?

It may be possible, but changing the riser affects the structure, the steps and the railing layout. Have the stair assessed before making changes.

Why does the railing height matter?

The height affects safety and comfort, because the handrail is used to steady the body while walking. Exact values should be checked against the applicable standard for your project.

Common mistakes to avoid

Choosing an infill pattern without considering who will use the stairs, or assuming the railing for a closed-riser stair will suit an open-riser design. Always plan the railing around the actual stair type and its users.

Our recommendation

Before ordering, decide whether the stair will be open or closed, consider children and pets in the household, and have the guard design checked against SI 1142 with your engineer. Ask for a written specification and drawing before production begins.

Summary

Open-riser stairs need more careful guarding and infill planning than closed-riser stairs, while closed risers offer simpler fixing and enclosure. Both can be finished with well-made metal railings suited to the stair and its users.
