Aluminium 1/4" Internal Corner - Cut to Size

Specifications

Product Overview

This aluminium 1/4” internal corner wallboard section is designed to create a clean, reinforced junction where two wall panels meet. It helps maintain straight, consistent internal angles for a tidy, professional finish.

Manufactured from lightweight, corrosion-resistant aluminium, it is suitable for renovation, fabrication and custom interior projects. Whether you’re completing a home improvement task or a light commercial fit-out, it provides a practical and durable corner solution.

Each section is cut to your exact measurements, so you can plan installations accurately and minimise unnecessary material adjustments on site.

If you’re ordering in volume or for a larger commercial project, we can support larger quantities through our parent company, Doré Metals.

If you’re unsure whether this profile is right for your project, our team can help.

Applications for Aluminium Internal Corner Wallboard Sections

Joining Wall Panels

• Internal corner joins can appear uneven if panels are not properly aligned. This section creates a clean junction between adjacent wallboards, supporting a more stable and consistent finish. It is commonly used with drywall, gypsum board and timber panelling.

Neat Internal Corner Finishes

• Unprotected internal corners often show rough edges once decorated. This profile defines a sharp internal angle for a cleaner, more professional appearance. It helps maintain uniform detailing throughout a room.

Residential Construction & Renovation

• Refurbishment projects can highlight imperfections where surfaces meet. Aluminium internal corners create a crisp transition that looks intentional and well-finished. They are ideal for DIY and light renovation work.

Commercial Interiors

• In offices, retail spaces and fit-outs, internal corners can experience regular wear. This corner section helps protect panel edges while maintaining a polished appearance. It supports a consistent finish across larger installations.

Hospitality Environments

• Guest-facing spaces rely on uniform detailing. Internal corner sections help maintain clean lines across corridors, rooms and shared areas. They offer a practical solution where presentation and durability both matter.

Educational & Healthcare Facilities

• Schools and healthcare environments benefit from clean, defined interior finishes that are straightforward to maintain. This profile helps create tidy internal junctions around wallboard panels. Aluminium’s corrosion resistance makes it suitable for busy settings.

Galleries & Museums

• Display environments require crisp detailing so focus remains on what’s being showcased. This internal corner section creates a neat backdrop around partitions and panels. It supports a consistent, professional presentation.

Theatres & Event Venues

• Temporary builds and stage installations can look unfinished without defined corners. This profile helps improve the appearance of internal angles in backdrops and sets. Its lightweight construction also makes handling and fitting straightforward.

DIY & Home Improvement Projects

• Achieving straight internal corners can be challenging without the right profile. This section simplifies the process and improves overall consistency. Ordering to your required dimensions can help reduce additional trimming during installation.
