PVC arris & corner angle beads
Technical product reference for UV-stabilised PVC arris and corner angle beads used in render repair, removal and reinstallation works on Australian Class 2 strata and commercial buildings. Covers UV stabilisation requirements, environment suitability, and product comparisons.
What are PVC arris and corner angle beads?
UV-stabilised PVC arris and corner angle beads are a lightweight, corrosion-resistant alternative to aluminium and stainless steel render beads. Unlike metal beads, PVC does not corrode in coastal or corrosive environments, making it a cost-effective choice for coastal facades where stainless steel beads would otherwise be required.

Rondo PVC Corner Bead (UV-stabilised)
UV-stabilised PVC arris corner bead
System Description
UV-stabilised PVC arris corner beads are a lightweight corrosion-resistant alternative to metal beads. They are suitable for use in all environments including coastal and corrosive zones. PVC beads do not corrode, making them suitable for applications where metal bead corrosion would be a risk. Confirm UV stabilisation grade, leg dimensions, and material thickness with Rondo for external UV-exposed applications. TODO: owner confirm — Rondo PVC arris bead specification, UV grade and leg dimensions.
Technical Properties
- UV-stabilised PVC — corrosion-resistant
- Perforated flanges for render key
- Suitable for exterior and interior
Limitations
- Less impact-resistant than heavy duty metal beads — avoid at high-traffic corners
- Confirm UV stabilisation grade for long-term exterior UV exposure
- TODO: owner confirm — Rondo PVC arris bead specification and UV grade
PROCUREMENT SOURCES
Confirm suitability with the current manufacturer TDS before specifying or applying.
System Description
USG Boral supplies PVC arris and corner beads for render edge protection. Confirm the specific USG Boral PVC arris bead product, leg dimensions, and UV stabilisation specification with USG Boral. TODO: owner confirm — USG Boral PVC arris bead specification and dimensions.
Technical Properties
- PVC — corrosion-resistant
- Exterior and interior render
- Confirm leg dimensions from USG Boral
Limitations
- TODO: owner confirm — USG Boral PVC arris bead specification
- Confirm UV stabilisation for exterior use
PROCUREMENT SOURCES
Confirm suitability with the current manufacturer TDS before specifying or applying.
System Description
PVC arris and corner beads are widely available as standard stock items through plasterboard merchants and render suppliers nationally. Confirm the UV stabilisation grade when purchasing for external exposed applications — not all trade-supply PVC beads are UV-stabilised to the same standard for long-term exterior use.
Technical Properties
- Standard stock item — widely available
- 25mm and 35mm leg profiles
- UV-stabilised PVC (confirm grade from supplier)
Limitations
- Confirm UV stabilisation grade for exterior exposed applications
- Less impact-resistant than metal heavy duty beads
- Confirm leg dimensions for render depth
PROCUREMENT SOURCES
Confirm suitability with the current manufacturer TDS before specifying or applying.
System Comparison
Side-by-side comparison of PVC arris and corner angle bead products. Confirm all product selections against the current manufacturer TDS before specifying.
| Product | Brand | Material | UV stabilised | Leg size | Impact resistance | Suitable environment | Primary use |
|---|---|---|---|---|---|---|---|
| Rondo PVC Corner Bead (UV-stabilised) | Rondo Building Services | UV-stabilised PVC | Yes — confirm grade | Confirm from Rondo | Lower than metal heavy duty | All environments including coastal | Exterior and interior render corners — corrosion-free |
| USG Boral PVC Arris Bead | USG Boral | PVC | Confirm from USG Boral | Confirm from USG Boral | Lower than metal heavy duty | All environments | Exterior and interior render corner protection |
| Trade-Supply PVC Corner and Arris Bead | Trade supply | UV-stabilised PVC | Confirm grade from supplier | 25mm or 35mm | Lower than metal heavy duty | All environments including coastal | Render corner protection — widely available nationally |
Do not confuse PVC arris beads with:
- Aluminium beads (metal — preferred in high-impact locations)
- Stainless steel beads (metal — preferred in high-corrosion environments)
- Mesh-wing beads (integral fibreglass mesh flange)
- Render stop beads (different profile — render termination not corner protection)
