Comprehensive Specification Standards for Aluminium Glass Internal Doors
In modern commercial and high-end residential architecture, OEM/ODM aluminium glass internal doors represent the intersection of structural minimal design and acoustic separation performance. Selecting the correct extrusion profile alloy, glass layup, and perimeter gasket geometry is paramount for procurement teams, real estate developers, and architectural specifiers aiming to achieve long-term operational durability.
1. Aluminum Alloy Extrusion & Metallurgy Standards
The structural integrity of indoor aluminum door frames depends directly on the extrusion billet composition and heat treatment process. At BrioWindow, profile geometries are extruded utilizing primary 6063-T5 or 6061-T6 structural aluminum alloys:
- 6063-T5 Alloy: Offers superior surface smoothness, making it the industry standard for high-end anodized and powder-coated slim interior partition frames. Yield strength ≥ 110 MPa.
- 6061-T6 Alloy: Specified for heavy-duty structural entrance doors, structural pivot posts, and large-span sliding panel stiles where higher tensile strength (≥ 240 MPa) is required.
- Wall Thickness Compliance: Interior slim profile stiles feature nominal wall thicknesses of 1.4mm to 2.0mm, exceeding standard residential requirements to guarantee zero frame warping over extended cycle operations.
2. Glazing Specifications & Acoustic Decibel Reduction
Internal glass doors serve as crucial sound isolation barriers between functional spaces, such as executive conference rooms, hotel suites, and private residential wings. Sound Transmission Class (STC) ratings are governed by glass mass, PVB interlayer damping, and perimeter seal compression:

STC 40 - 43 dB |
Conference Rooms, Luxury Hotel Guest Rooms, Music Studios |
| Switchable Smart PDLC Glass |
6mm + 1.52PDLC + 6mm |
STC 37 - 39 dB |
Instant Privacy Workstations & Modern Medical Suites |
3. Surface Finishing Technologies & Environmental Corrosion Resistance
Interior doors must withstand continuous tactile friction, cleaning detergents, and varying indoor humidity levels. BrioWindow utilizes three primary automated surface treatment pipelines:
- Electrostatic Powder Coating: Utilizing Qualicoat-certified AkzoNobel or PPG fluorocarbon powders. Provides exceptional scratch resistance with a coating thickness between 60 to 80 microns.
- Anodizing & Electrophoresis: Creates a hard aluminum oxide layer (15–25 microns thick) available in brushed black, champagne gold, satin bronze, and titanium silver. Impervious to fingerprint oils and color fading.
- Wood Grain Thermal Transfer: Combines the structural benefits of aluminum alloy with natural timber aesthetics, ideal for hotel guest room doors requiring warm tactile finishes with zero organic warping risk.
