Handrail fittings are counted point by point, not ordered as a set. A straight balcony rail may need no more than an end cap at each end and a pair of flanges to fix it, while a stair that turns at several landings and branches onto a second flight may need elbows, tees and base plates at a dozen positions. The type of handrail fitting — elbow, tee, flange, bracket or end cap — follows the geometry of the railing rather than the other way round. The same railing may also pass from an indoor stair to an outdoor terrace, which changes the stainless steel grade the handrail fittings should be made in. This guide works through four common settings, then sets out how handrail fittings and tube are matched by diameter. Jianlai supplies handrail fittings in SS 201, SS 304 and SS 316, with satin, mirror, matte black and gold finishes.
Four features decide which handrail fittings a railing needs: where it turns, where it branches, where it is fixed, and where it ends. The usual mapping is simple: a turn takes an elbow, a branch takes a tee, a fixing point takes a flange or base plate, and an open end takes an end cap. Count those four features on the drawing and the handrail fitting list follows.
The second measurement is the tube. Handrail tube is bought by outside diameter, and the handrail fittings are bored to match. 38.1 mm, 42.4 mm and 50.8 mm are the common sizes; other diameters are available on request. Take the figure from the tube order rather than from the project description.
Get the count and the diameter right, and the rest of the selection comes down to material and finish.
A stair changes direction only where a landing turns; a straight flight with a mid-landing carries on in the same line. Each change of direction needs an elbow in the corresponding angle. Where a second flight leaves a common landing, the junction usually takes a tee rather than two elbows.
Start and finish points need the same attention. The foot of a flight commonly lands on a floor flange or base plate; the head commonly terminates against a wall with a wall flange, or ends free with an end cap. On a long flight the handrail is usually continuous, so the handrail fittings sit at the changes rather than at intervals along the straight.
Stairs inside a building are normally dry, which is where SS 201 has a place on cost. Where the stair is external, or the building sits near the coast, the grade moves up before the finish is discussed.
A balcony railing is often straight along much of its length, so the emphasis shifts to two details: the plan corners and the fixing surfaces.
Plan corners take an elbow in the angle the drawing shows. A square corner and a splayed corner are different parts, and the angle should be read from the plan rather than assumed. Where the handrail returns into a wall, a wall flange closes it; where it terminates in open air, an end cap does.
The fixing surface matters as much as the type. A concrete slab, a wall with a cavity and a steel member present different conditions, and the base plate or flange has to suit the one in the build-up. Confirm the substrate before the order is placed, so the plate form matches what the site will present.
Terraces exposed to weather also raise the question of how the railing will look after a few seasons, which brings grade and finish back into the decision.
Chlorine and salt are the two conditions that usually decide the grade. SS 316 is the choice for pool surrounds and for sites within reach of sea spray. SS 304 covers general outdoor work where chlorides are not concentrated. SS 201 is intended for indoor, dry locations. Settling the finish first and the grade second is a common way these projects go wrong: the surface is what you see, but the grade decides how long the railing holds up.
Finish then follows the design intent. Satin carries a fine directional grain that keeps reflections low and reads evenly along a long handrail. Mirror gives a bright, crisp line and wipes clean with a cloth after splashing. Matte black recedes against water, planting and paving, so the glass reads as an uninterrupted plane. Gold adds a warm accent where the railing is meant to be noticed, and pairs with brass or bronze hardware elsewhere in the scheme.
For any coloured finish, ask the supplier to confirm the coating process, the adhesion testing behind it and its performance outdoors, since these vary between suppliers. The range carries a 3-year warranty.
In a commercial building the railing is read as one system. The handrail tube, the handrail fittings, the posts and the glass clamps should share a grade and a finish, because a satin elbow beside a mirror post reads as a mismatch at a glance.
Where a project is built in phases, finish continuity matters between deliveries. Where a job spans several orders, confirm that later deliveries match the finish of the first rather than assuming they will.
Small parts deserve their own line on the order. End caps, decorative covers and fixing plates are the parts that tend to go missing on site or get damaged during later trades, and they are awkward to source on their own once the railing is complete. A small surplus ordered with the main quantity costs less than a second shipment.
Every handrail fitting is sized to the outside diameter of the tube it receives, so the interface is decided by one number. 38.1 mm, 42.4 mm and 50.8 mm are the common sizes. For any other diameter, confirm the size with the supplier before the order is placed.
The trap is nominal naming. Tube is often described by a rounded figure: a handrail sold as 42 mm is normally 42.4 mm across the outside, and the handrail fitting that suits it is the 42.4 mm one. The two numbers describe the same tube, but only the outside diameter identifies the part. When a size goes on an enquiry, say whether it is the nominal name or the measured outside diameter, so the part is matched to the tube rather than to the label.
One tube diameter for the whole railing is the simpler discipline. Mixing two sizes on the same railing means the elbows and tees at the junction belong to one size and not the other, and the joint shows it. End caps follow the same rule, sized to the outside diameter, with the cap depth chosen to suit the wall thickness of the tube in use.
That is the whole check: one confirmed outside diameter, carried through every handrail fitting on the railing.
Setting | Handrail fittings used along the railing | Suggested grade |
Indoor stair | Elbows at landings, tees at branches, floor flange at the foot, end cap at the head | SS 201 or SS 304 |
Balcony or terrace | Plan-corner elbows, wall flange at returns, brackets where panels are carried, end caps | SS 304 |
Pool surround or coastal site | Elbows, tees, base plates and end caps across the whole railing | SS 316 |
Commercial or public space | Full set in one matched grade and finish, plus a surplus of the small parts | SS 304 or SS 316 |
The four settings share the same logic: read the layout, choose the type for each point, then settle grade and finish. The full range can be reviewed on the Jianlai handrail fittings product page. For a specific project, confirm the measured tube diameter and the fixing surface against the relevant data sheet before ordering.
