Stainless Steel Render Beads

Stainless steel render beads are slim, strong strips that guide plaster and protect edges, helping walls stay neat while resisting knocks, weather, and wear over time.

Made from stainless steel, they do not rust, making them perfect for damp walls or exposed corners that see daily wear and tear.

What Are Stainless Steel Plaster Beads?

Stainless steel plaster beads keep plaster edges straight, corners sharp, and surfaces safe from bumps or weather. Ideal for external walls, window frames, and busy areas, these beads are built to last, resistant to rusting, and ready for heavy rain, frost, and coastal conditions.

Most beads have a central strip with small perforated wings that hold the plaster firmly against the wall. Some come with mesh for extra strength, or special profiles to create neat reveals and modern shadow lines, mainly for external render systems.

What Is A Stainless Render Bead Used For?

Stainless steel render beads are the heavy-duty option in the bead family.

Here’s where they are typically used:

1. Exterior walls in tough climates. They will not corrode, pit, or swell, so the render edges stay sharp for years.
2. Coastal areas. They do not rust when exposed to salty, humid air.
3. Damp-prone zones. If a wall tends to stay damp – shady garden walls, areas behind gutters, lower wall sections close to paving – stainless steel is often specified to avoid corrosion marks coming through the render.
4. High-traffic exterior corners. Stainless steel corner beads give a tougher, more durable edge on exposed corners prone to impact.
5. Commercial and public buildings. They maintain their form and finish in heavy-use areas.
6. Where Building Regulations require metal beads. Some render systems or specifications require non-corroding metal edges, making stainless steel the ideal choice.

Types Of Stainless Beads For Render

In the UK, six main types are widely used:

1. Stainless Steel Corner Beads

L-shaped beads for external corners that protect edges from knocks and weather while keeping lines straight. The stainless angle bead is used on house corners, garden walls, and commercial buildings.

2. Stainless Steel Render Stop Beads

The stainless steel stop bead marks the end of a render run. Perfect around window reveals, door openings, or anywhere the render needs a neat finish.

3. Stainless Steel Movement / Expansion Beads

These accommodate thermal and structural movement to prevent cracking. They are added to large wall sections, long external elevations, or areas prone to cracking from temperature changes.

4. Stainless Steel Bellcast Beads

Also called drip beads. Fitted at the bottom of external walls to direct rainwater away from the render, preventing streaks and staining.

5. Stainless Steel Render Corner Mesh Beads

These are corner beads with an integrated mesh wing. They give extra grip and reinforcement, especially useful for thick-coat or basecoat render systems. The external stainless steel angle bead with mesh protects exterior corners from weather-related degradation.

6. Stainless Steel Shadow Gap / Render Reveal Beads

Used to create clean recess lines or modern shadow gaps around windows, doors, and architectural features. Common in contemporary builds where crisp detailing matters.

How to install stainless steel render beads?

1. Clean the wall.
2. Measure and mark. Hold the bead in place, then mark the length and position using a pencil.
3. Resize the bead. Cut the bead, keep it straight to ensure it sits flush against the wall.
4. Apply dabs or a thin line of adhesive or mortar.
5. Position the bead. Press gently onto the wall, ensuring wings sit flush. Check alignment with a level.
6. Adjust before it sets. Correct any twist, tilt, or unevenness.
7. Render over the bead. The wings lock the render in place. Smooth as needed.
8. Finish and cure. Smooth any ridges or bumps and allow the render to cure fully.

How much are stainless steel plaster beads?

It depends on the type of stainless steel bead (angle, stop, etc.), the length, thickness, finish, steel grade, and whether you are buying in packs or individual plaster beads.

If you are buying individual 3m stainless beads, expect to pay £8–£15 each, depending on the profile. For trade packs or bulk buys, you might get them for £4–£6 each.

When to use stainless steel instead of galvanised render beads?

Both stainless steel and galvanised beads protect corners and edges, but the difference is in durability and the environment. Stainless steel is the better choice in:

• Harsh or wet conditions
• High-impact or high-traffic areas
• Projects that require a durable, low-maintenance finish
• Buildings with specific metal requirements
