Manufacturing Process
QueenCore’s 90° internal corner sandwich panels are produced using advanced automated systems to ensure precision and consistency:
- Material Selection – High-grade insulation core and metal facings are chosen based on application requirements.
- Cutting & Profiling – Panels are precisely cut to size, and edges are shaped for a perfect 90° corner fit.
- Bonding – Core material is adhesively bonded to metal facings under controlled pressure and temperature.
- Curing & Finishing – The panels undergo curing for optimal strength, followed by surface finishing (e.g., coating, embossing).
- Quality Inspection – Each panel is checked for dimensional accuracy, adhesion strength, and surface integrity.
Applications
Our 90° internal corner sandwich panels are widely used in:
✔ Cold Storage & Freezer Rooms – Ensures thermal efficiency with airtight corners.
✔ Cleanrooms & Laboratories – Provides smooth, easy-to-clean surfaces.
✔ Industrial Partitions & Warehouses – Enhances structural integrity.
✔ Commercial Buildings – Delivers a sleek, modern interior finish.
✔ Modular Construction – Facilitates quick assembly with precise corner joints.
Installation
Installing QueenCore’s internal corner panels is straightforward:
- Preparation – Ensure the substrate is level and clean.
- Panel Alignment – Position the 90° corner panel against the wall junction.
- Fixing – Secure the panel using mechanical fasteners (screws, rivets) or adhesive.
- Sealing – Apply sealant along joints for airtight and waterproof performance.
- Finishing – Cover fasteners with trim caps for a polished look.
