How our vertically integrated factory operations translate to cost reduction, quality control, and faster cycle times.
We melt and cast our own billet alloy in-house. This gives us full authority to adjust chemical compositions to optimize physical properties, reduce extrusion grain boundaries, and ensure the highest purity for mirror-finish anodizing.
Precision machining, CNC operations, and chemical surface treatments are conducted in-house. By removing third-party logistics and markup costs, we offer superior mechanical finishes at highly competitive prices.
Our comprehensive "one-stop" manufacturing chain eliminates external delays. Billet casting, extruding, machining, and treatment lines are sequenced to compress lead times to the absolute minimum.

Large-scale architectural and LED bathroom mirrors require frame profiles that resist structural bending and torsional twist. When heavy silvered glass is joined with moisture-sealing back panels and electronic drivers, the frame must support constant shear loads.
For frames exceeding 1.2 meters, deflection calculations determine the structural limits. Wall thicknesses are optimized between 1.2 mm and 2.5 mm. Extruding profiles with internal reinforcing ribs provides high structural strength while minimizing overall weight.
While 6061 offers superior tensile strength (≥ 260 MPa) for structural framing, it is prone to surface grain lines after extrusion, making it less suitable for high-finish decorative parts. For mirror frames, 6063 and 6463 alloys are preferred.
6463 is formulated with low iron content, preventing cloudy spots during chemical polishing to achieve a highly reflective, mirror-like finish.
| Alloy Grade | Temper | Tensile Strength | Yield Strength | Elongation | Recommended Applications |
|---|---|---|---|---|---|
| 6063 | T5/T6 | ≥ 160 MPa | ≥ 110 MPa | ≥ 8% | Standard LED mirror frames, satin anodized borders |
| 6463 | T5/T6 | ≥ 145 MPa | ≥ 105 MPa | ≥ 8% | High-gloss bright-dipped chemical polished frames |
| 6061 | T6 | ≥ 260 MPa | ≥ 240 MPa | ≥ 10% | Heavy-duty structural backing, bracket mount assemblies |
| 7075 | T6 | ≥ 540 MPa | ≥ 480 MPa | ≥ 7% | Ultra-high-load brackets, structural connector bars |
Mirror frame profiles are exposed to high-humidity bathroom environments. Our chemical finishing methods provide long-lasting corrosion resistance and surface stability.

A look at how Foshan Golden Source integrates automation, tooling manufacturing, and vertical processing to support global procurement demands.
By using direct-chill (DC) casting tables, we control the purity of our aluminum billets. Electromagnet stirrers and ceramic foam filtration systems minimize hydrogen porosity and non-metallic inclusions, preventing surface defects during fine machining.
Our tooling division designs and machines dies using precise H13 steel. Nitrogen-gas cooled extrusion presses maintain consistent extrusion temperatures, preserving tight tolerances (+/- 0.1 mm) for complex profiles.
Our CNC facility is equipped with multi-axis machining centers (handling lengths up to 6 meters). We perform precise miter cutting, drilling, pocket milling for LED drivers, and thread tapping for seamless frame corner assembly.
Our facility holds certifications including ISO9001, ISO14001, and ISO45001. To meet strict EU environmental regulations, we also maintain updated GRS (Global Recycled Standard) and RCV certifications, ensuring full compliance with REACH and RoHS standards.
Future-proofing smart home interiors through structural integration and carbon-reduced manufacturing.
We design custom profiles with built-in channels for LED strips, touch control plates, motion sensors, and defogging heat pads, ensuring clean wiring and simple installation.
Using our Global Recycled Standard certification, we offer mirror frame extrusions made from post-consumer recycled aluminum, helping global brands meet their Scope 3 emission targets.
We are refining our extrusion and CNC processes to achieve tolerances under 0.05 mm. This supports the production of ultra-thin, frameless glass assemblies for high-end hotels.
Technical answers to common engineering, procurement, and surface treatment questions from global OEMs.
6463-T5 is designed with low iron (Fe) content (typically < 0.15%). This helps prevent surface clouding or "milky" areas during chemical polishing or bright dipping. 6063, while strong, contains higher iron levels, which can cause minor streaks or haziness that reduce reflectivity.
For humid bathroom environments, we recommend a minimum anodizing thickness of Class II (10 to 15 microns). This provides reliable protection against corrosion from moisture, condensation, and chemical cleaners.
We cast our aluminum billets in-house, allowing us to control trace elements. We verify compliance through regular third-party chemical laboratory tests. Our GRS certification further ensures our recycled aluminum matches these environmental standards.
Designing and manufacturing a custom extrusion die takes 10 to 14 working days. Producing initial sample extrusions and finishing them takes another 7 to 10 days, depending on the complexity of the profile shape.
Yes. Our CNC facility handles profile lengths up to 6 meters. We mill pockets for LED drivers, drill mounting holes, and cut mitered corners for seamless, ready-to-assemble frames.
High-finish profiles are protected with a peelable surface film. We then pack them in paper sleeves, wrap them in heat-shrink film, and place them in wooden crates to prevent movement and friction during transit.
Our standard MOQ is 500 kilograms per profile design. This aligns with the minimum billet run for our extrusion presses to maintain consistent temperature and surface quality.
Yes, we match colors based on standard RAL or Pantone codes. We also match physical color chips provided by customers, adjusting the gloss level from matte (10% gloss) to high-gloss (90% gloss).
