90 Degree Internal Corner
Product Description
90° Internal Corner
Product Introduction:
Our 90° Internal Corner is a precision-engineered trim profile designed to create a clean, waterproof, and professional finish at internal corners (inside corners / concave corners) where two wall panels meet at a 90-degree inward angle. This essential accessory provides a seamless transition between adjacent panels while protecting raw edges from moisture ingress and ensuring long-term durability in wet environments .
Key Features：
1.Neat Internal Finish – Creates a sealed and tidy junction between two wall panels meeting at an internal right angle, concealing raw cut edges for a polished appearance
2.Waterproof Protection – Prevents moisture from penetrating panel edges, effectively blocking water ingress that could cause swelling, delamination, or mold growth behind the wall cladding
3.Durable Construction – Manufactured from high-quality materials including rigid PVC-U, aluminum, or stainless steel – resistant to corrosion, impact, and warping over time
4.Easy Installation – Pre-formed 90° angle enables fast, reliable fitting with adhesive or mechanical fixings. Can be easily cut on site to match precise corner heights
5.Low Maintenance – Smooth, non-porous surface is wipe-clean and requires no painting or additional treatment. Resistant to mold and fungi
6.UV-Stabilised (PVC options) – Maintains colour stability and dimensional integrity under normal temperature and humidity conditions
