7*7*1mm Aluminum Alloy Corner Molding

Key Advantages

• Precise dimensions: 7mm × 7mm equal legs, 1mm wall thickness. Angle accuracy of 90° ± 0.5° Ensures proper fit on standard corners.
• Corrosion resistance: No rust formation under normal indoor temperature and humidity. Neutral salt spray test (NSS) ≥72 hours without pitting.
• Abrasion resistance: Surface hardness withstands regular cleaning tools and light impacts without visible scratches.
• Shape retention: Straightness deviation ≤1 mm/m along the length. Minimal bending under stacking or after installation.
• Surface finish: Anodized layer thickness ≥5 μm. Metallic appearance without requiring additional coating.

Product Specifications

Application Scenarios

• Interior wall corner protection (hallway corners, window trim sides)
• Right-angle edging for wall panels or wood veneers
• Cove lines at ceiling-to-soffit junctions
• Metal edge banding for exposed corners of cabinets and wardrobes
• Narrow transition strips for wall color separation lines
• Corner finishing for metallic insert strips on feature walls

Frequently Asked Questions and Precautions

Q: Will dark oxidation spots appear after installation?
A: Not under normal dry indoor conditions. In environments with relative humidity >85% and poor ventilation (e.G., Untreated basement walls), seal both ends with silicone to prevent moisture ingress behind the molding.

Q: How to cut the profile?
A: Use a hacksaw or a small table saw with a carbide-tipped aluminum blade. Deburr the cut ends with a fine file to avoid scratching adjacent surfaces during installation.

Q: Can it be used on rounded corners?
A: No. This rigid profile is designed for 90° standard corners. For rounded corners, use a flexible edge trim or custom-curved metal strip.

Precautions

• Clean substrate to remove dust, grease, and moisture. If surface flatness exceeds 1 mm/m, level it first to prevent hollow spots or edge lifting.
• Apply adhesive in dots or a wavy pattern on the back side. Avoid adhesive squeezing onto the visible face.
• Do not use acidic or alkaline cleaners (e.G., Oxalic acid, sodium hydroxide solution). Use neutral pH cleaners for maintenance.
• Store horizontally on dry wooden supports. Avoid heavy stacking or bending. Stack height ≤1.5 M.
