antique brass large wall mirror factory - Bulk Supply and Specification Guide
The Problem Buyers Keep Paying For
| Dimension (mm) | Frame Depth (mm) | Est. Unit Weight (kg) |
|---|---|---|
| 600 x 900 | 25 - 30 | 5 - 7 |
| 1200 x 2000 | 40 - 50 | 18 - 25 |
| 1500 x 2400 | 50 - 70 | 35 - 45 |
Deflection under load governs the structural integrity of large-format mirrors. Thin-walled alloy frames often bow under the weight of the glass, leading to silvering separation or optical distortion. We utilize reinforced sub-channel profiles to ensure the frame remains flat during wall mounting installation.
Low-grade antique patination often fails because the chemical reaction is applied as a surface-level paint rather. Our process involves a multi-stage electroplating followed by a clear-coat that prevents oxidation in high-humidity hospitality environments.
Matching the Product to the Buyer's Need
Consistency depends on the mounting-point-to-frame-weight ratio. Heavy-duty Z-brackets prevent the tilting common in lower-grade retail units. For large-scale residential projects, 6mm float glass reduces the risk of stress fractures compared to standard 4mm alternatives.
Structural Stability Note
The internal mechanical cleat system distributes the load across the entire perimeter of the frame. This prevents localized pressure points that typically cause the glass to crack over years of thermal expansion.
Customisation Options and Their Limits
Finish and Material Selection
- Electro-plated Antique Gold, Aged Bronze, and Brushed Brass finishes.
- Frame materials range from zinc alloy for detailed molding to solid-cast brass for premium tiers.
- Edge beveling options available from 10mm to 50mm varying widths.
Technical Constraints
- Maximum glass thickness is capped at 8mm for frames exceeding 2 meters in height.
- Custom mould production requires a 45-day lead time for tooling fabrication.
- Mirror-backing is limited to standard silvering or moisture-resistant copper-based coatings.
Balance and load analysis shows that wider frame profiles require thicker wall-sections to prevent sagging. We limit custom frame widths to 15cm to ensure the material remains rigid without internal steel reinforcement.
Requirements by Buyer Segment
Hospitality buyers demand high-moisture resistance to prevent "black spot" oxidation in bathrooms and hotel lobbies. We specify an anti-corrosive backing silvering process for these bulk orders.
Retail distributors prioritize flat-pack compatibility and rapid-assembly mounting hardware. Our retail-ready units include pre-installed hardware kits to reduce labor costs for the end-user.
Inspection Items and Test Methods
| Test Parameter | Methodology | Acceptance Criteria |
|---|---|---|
| Corrosion Resistance | Salt spray test (ASTM B117) | No visible pitting after 48 hours |
| Coating Adhesion | Cross-cut tape test | Rating 4B-5B |
| Optical Clarity | Lightometer inspection | Distortion < 1% |
Packing, Marking and Freight Configuration
Freight protection is the primary driver of cost for large mirrors. We utilize custom-built wooden crates with internal high-density PE foam bracing to absorb vibrations during sea transit.
Each crate is marked with center-of-gravity indicators and orientation arrows. Moisture-desiccant packets are included in the wrap to prevent silvering degradation during containerized shipping.
Questions Buyers Ask Before Ordering
Can the frames support custom-cut glass weights?
The capacity depends on the frame thickness and the alloy used. For a 30mm-deep zinc frame, we can safely support 6mm glass up to 40kg when mounted with heavy-duty wall studs.
What is the finish consistency across different batches?
Batch consistency is maintained by using master alloy samples for every production run. We monitor the chemical composition of the patination to ensure the color Delta matches the approved OEM standard.
