Mixing up these stair parts leads to failed inspections, rework, and risk. Here’s a plain-English guide so you pick the right component the first time and stay compliant.
A handrail is the graspable support you hold while using stairs or ramps; a railing—often a guardrail—acts as a barrier along open edges to keep people from falling. Typical handrail height is 34 inches–38 inches; guards are commonly 36 inches (residential) or 42 inches (commercial) per widely adopted building code.
If you’ve ever asked, Qual é a diferença? between a corrimão e um corrimão, here’s the simple answer: the corrimão é something to hold for balance; the corrimão (often a guarda-corpo) acts as a barrier along an open side. One part guides your hand; the other keeps edges secure.
Think of a escada you use every day. The corrimão runs along the wall or side of the stairs, while the guarda-corpo stands at deck edges, landings, or a walkway para prevent people from falling. Different jobs, different code requirements, and often different shapes—even when they look similar. This is the key differences buyers and installers need to remember.
Under the International Codes widely adopted in many regions, altura do corrimão is measured above the stair tread nosing and typically must fall between 34 inches and 38 inches. On ramps, the rule is similar, and it also applies to ramps with a rise that meets your local trigger. Guard height is typically 36 inches for residential and 42 polegadas for commercial settings (verify your jurisdiction).
When the open side of floors, landings, or portions of the stairway exceeds a 30 inches drop, railings are required para keep people from falling. That’s why the top rail must meet specific height and opening limitations. Always check your código de construção—local amendments can vary.

A guarda-corpo surrounds a balcony edge, landing, or open side so it can keep people from falling. In the IBC, required guards in most commercial occupancies are not less than 42 inches in height. In the IRC for dwellings, guards are not less than 36 inches in height. Always verify the adopted year and local amendments before ordering.
On stairs, o difference between a guardrail e um corrimão becomes obvious: the guard’s top may also serve as the hand-grip only if it sits at 34 inches–38 inches and is graspable; otherwise you add a separate corrimão at hand level. Stair railings are often confused for grip rails, but in code language they have different performance rules.

Most codes say handrails are required on stairs with a certain number of risers and on certain ramps. Handrails must be installed at a consistent height, measured from the stair tread nosing, and handrails must extend at landings as your jurisdiction specifies. You’ll also see rules on returns at the edge of the stairs for snag-free transitions.
Grip comfort matters. The surface of the handrail should be smooth and continuous. Round or oval profiles with a finger recess on both sides are typical, making the rail graspable for small and large hands. This is one reason handrails provide reliable assistance on every flight of stairs.

Common types of handrails include round tube, square tube, and molded wood. Popular handrail material choices are steel handrail, aluminum handrails, wood handrailse wrought iron handrails. Pick for durability, cost, and look; match the sistema de corrimão e o escada environment.

Bom handrail design starts with the hand. Many codes expect a round 1¼–2″ diameter (or a shape with a finger recess on both sides). That keeps the grip comfortable and consistent for using stairs. Even small details—like how far the rail must stand off the wall—change comfort and compliance.
Don’t forget stair parts such as posts, brackets, and balaústres. Confirm minimum height rules, openings, and structural loads—especially on schools and hospitals—and align them with your staircase design.

On very wide runs, intermediate handrails are required so every user can reach a grip; some venues add a center rail so portions of the stairway are easier to navigate. In many occupancies, stair rails must be nearly continuous except where they pass support posts, helping users move without breaks.
Start by placing a rail on least one side. Then consider the sides of stairs ou o side of a stair where traffic is heavy. In high-traffic buildings, intermediate handrails reduce crowding and improve flow.
Em um varanda ou walkway, o guarda-corpo circles the perimeter to keep people from falling. The hand-grip may be separate or integrated, depending on height. If the top is set at 34 inches–38 inches and is graspable, it can double as the grip; if it’s taller, install a dedicated grip rail below. That’s the guardrail and a handrail relationship in practice.

Tip: The top guard rail must also limit openings; for example, the IBC limits sphere size through the guard. Always read the local text your AHJ enforces. (ICC Digital Codes)

A library updated an aging escada. We measured each stair tread, set a consistent grip at 34 inches, and added a center rail because intermediate handrails are required on wide runs. The result: better stair safety, clean lines, and smoother traffic. On the landing, we set guards to the correct inches in height and verified openings for children’s safety.
Is a stair rail the same as a handrail?
No. A trilho da escada may refer to the top of a guard along the open side of a stair, while the corrimão is the graspable member you hold. Standards clarify both pieces so installers don’t mix them up.
Where must a handrail be installed?
Most codes require a grip on stairs (and on certain ramps). In many places, a grip appears on at least one side of the stairs; wide runs may need more. Check your jurisdiction before ordering.
Can the top of a guard double as the handhold?
Sim-if it sits at 34 inches–38 inches and is graspable. If the guard is higher—say 38 inches or more—add a separate grip that matches the hand rules.
Which materials fit different projects?
Stainless is robust indoors and out; aluminum handrails are light and corrosion-resistant; wood handrails feel warm inside; wrought iron suits classic façades. Match to climate, budget, and style.
Do rails on schools need special attention?
Yes. Crowds, accessibility, and abuse loads matter. Many designers choose round profiles and extra supports so the handrail and stair system lasts longer.
What if my inspection mentions “stair rails must be continuous”?
That’s a common plan note. It means the grip runs smoothly along the whole flight of stairs without breaks, aside from code-allowed interruptions.
