Cleanroom Wall and Ceiling Systems
External 90-Degree Cleanroom Corner Profile
A crisp L-shaped aluminum trim that encloses and protects the exposed edges of a square external cleanroom wall corner.
- Crisp external 90-degree finish
- Protects two exposed panel edges
- Low-profile square appearance
- Anodized or powder-coated aluminum
Product Introduction
The External 90-Degree Cleanroom Corner Profile finishes a projecting square corner without adding a large radius. Two legs bridge the adjacent wall faces, covering vulnerable panel edges and creating straight sealant boundaries. The profile is suited to architectural layouts that require a compact, crisp corner line and is distinct from the rounded external coving profile used for soft-edge protection.
Key Features
Both panel edges are enclosed beneath a durable aluminum trim.
The low-profile legs preserve a clean architectural appearance.
Concealed attachment methods minimize visible hardware on adjacent faces.
Continuous profile edges guide neat sealing along both sides of the corner.
Customer Product Concerns
Square outside corners expose two panel edges to view and impact, making alignment and edge protection especially important.
Bare panel edges at a projecting corner can dent or delaminate after minor contact.The aluminum angle spreads contact across both faces and covers the vulnerable edges.
Unequal panel cuts produce a visibly crooked external corner line.Straight profile legs establish a crisp reference edge over the underlying joint.
Large-radius guards change the intended square architectural geometry.The compact 90-degree section preserves a sharp, low-profile corner appearance.
Sealant applied directly over an open panel junction can crack or look irregular.The profile creates stable, narrow interfaces for sealant on both adjoining faces.
Typical Applications
Square external cleanroom partitionsDoor and window return cornersModular enclosure outside edgesLaboratory wall projectionsArchitectural panel corner finishing
Technical Parameters
This product is the square external angle in the profile range. It should not be confused with the separate convex external corner cover designed around a rounded radius.
