Explore our flagship collection of bespoke castings, luxury accents, and architectural hardware engineered for upscale commercial environments.
Established in 2015 in the manufacturing heart of Guangdong, China, Buterfloge represents an integrated brand and creative platform that seamlessly bridges research, design innovation, and bespoke fabrication. Rooted in classical, retro, and refined design languages, we design structural brass furniture and luxury accents that combine modern ergonomic comfort with a historic neoclassical aesthetic.
By using age-old metalworking methods such as sand casting and lost-wax investment casting alongside precision CNC machinery, Buterfloge satisfies the demanding quality levels required by royal estates, boutique hospitality chains, and luxury architectural firms around the world.
Under the creative direction of founder Rona Chu, our designs balance nostalgic references with functional utility. Having spent decades studying classic antique bathroom designs and vintage home styles, Rona Chu has infused the brand with an artistic appreciation for timeless forms, organic lines, and tactile textures.
Understanding the design trends, raw material selection, and technical certifications driving luxury furniture procurement.
In high-end real estate, luxury resorts, and boutique hospitality spaces, solid brass is increasingly selected for contract dining chairs and accents. Brass has a natural weight, inherent resistance to corrosion, and develops a rich patina over time that cannot be successfully replicated by anodized aluminum or plated steel.
Contemporary commercial specifications demand furniture that meets strict durability standards while making a bold aesthetic statement. This has shifted procurement focus toward high-end CNC-milled structural framing and lost-wax cast joints. These production methods guarantee structural integrity under continuous, heavy commercial usage.
Furthermore, global buyers seek manufacturers capable of providing end-to-end customization (OEM/ODM). This includes engineering custom profiles, developing custom surface patinas, and designing integrated upholstery systems that meet international safety standards.
Our manufacturing complex in Guangdong combines advanced CNC tooling with traditional metal casting techniques.
We source certified copper alloys and use strict engineering tolerances to guarantee structurally sound contract furniture.
| Alloy Parameter | Technical Details | Performance Output | Compliance Reference | |
|---|---|---|---|---|
| Alloy Composition | HPb59-1 / H62 Solid Brass (Cu 57-60%, Pb < 1.5%, Zn Balance) | High density, excellent ductility, resistant to stress cracking. | ASTM B16 / B16M Standard | |
| Structural Casting | Lost-Wax Investment Casting (Vacuum-assisted pour) | Pore-free microstructure, clean surface rendering, complex geometry. | ISO 9001:2015 Foundry Spec | |
| Surface Hardness | Brinell Hardness Scale ≥ 75 HB | Resistant to surface indentation, scratches, and wear. | GB/T 231.1 Test Standards | |
| Finish Options | PVD Titanium Gold, Hand-Rubbed Patina, Anti-UV Clear Lacquer | Corrosion protection, stable finish retention, non-tarnishing. | ASTM B117 (96-Hour Salt Spray) | |
| Load Integrity | Heavy-Gauge Tubular Frames & Cast Joints | Tested to withstand high static load without failure. | ANSI / BIFMA X5.1-2017 |
We refine and pour our own proprietary brass formulations. This guarantees that all structural frame elements are free from inclusions and porosity that weaken standard castings.
Using high-end multi-axis CNC routers and mill-turn centers, we machine our joints, fasteners, and mounting plates to within a 0.02mm tolerance for a seamless mechanical fit.
From raw, organic hand-rubbed patinas that develop naturally over time to resilient Physical Vapor Deposition (PVD) titanium coatings that resist oxidation in seaside environments.
We facilitate hassle-free global importing with comprehensive compliance, logistics support, and robust product warranties.
Shipping heavy, high-value solid brass products requires specialized drop-testing, multi-layered protective foam, and reinforced crate packing. Our logistics team coordinates sea freight, customs clearance, and port delivery, while ensuring compliance with regional documentation rules.
Furthermore, all Buterfloge products are packaged with custom timber crates (ISPM 15 certified for international customs) to guarantee zero-defect arrivals. We provide direct customs clearance documentation support to prevent import delays for commercial contractors.
To meet the needs of international hospitality and corporate real estate projects, we provide complete certifications for wood, textiles, and metals. This includes CAL 133 fire retardancy compliance for cushions and REACH/RoHS compliance for all liquid and solid finishes.
How we are engineering the future of high-end furniture manufacturing with sustainable processes and advanced technology.
All brass scrap, CNC chips, and casting gating systems are remelted and recycled in our facility. This minimizes our raw material footprint and maintains strict purity controls.
We are transitioning our hospitality contract collections to low-lead and lead-free bismuth brass alloys. This ensures safety and compliance with international health regulations.
We use generative design software to optimize chair frame structures. This reduces excess metal weight while increasing overall strength at key high-stress joints.
Answers to technical, logistics, and design customization questions for architects, designers, and supply chain managers.
For standard production runs, the lead time is 45 to 60 days from technical drawing approval and deposit confirmation. Bespoke tooling and custom lost-wax molds require an additional 15 to 20 days for design engineering, sample casting, and validation.
All frame mockups undergo independent testing in accordance with ANSI/BIFMA X5.1 and EN 16139 L2 standards. We use thick-walled solid brass extrusion profiles and custom-casted knuckle joints. These joints are internally pinned and silver-soldered to prevent loose joints under heavy public use.
Yes, we offer a variety of surface treatments. These include physical vapor deposition (PVD) for high-wear resistance, electroplating, chemical patination, and hand-rubbed antique oil bronze. We coat our metal frames with an automotive-grade, UV-cured acrylic lacquer to protect against oxidation in coastal environments.
Our standard MOQ for custom cast or CNC-machined brass dining chairs is 50 units. However, we support lower quantities for luxury boutique hospitality projects or custom residential commissions depending on material availability and design complexity.
Yes. We source traceable copper and brass alloys that comply with REACH and RoHS standards. All textiles and foam inserts used in our chairs can be sourced to meet CAL 133, BS 5852, and other local flammability standards upon specification.

The design philosophy at Buterfloge is built on classical furniture traditions and retro nostalgia. We design spaces that evoke memory and emotion.
"A retro bathroom product, a cast brass ornament, or a unique fragrance can bring back fond memories," says founder Rona Chu. "I remember my grandmother who would spend hours in the bathroom every day. The elegant impressions she left on me are key inspirations behind the Buterfloge brand."
This heritage is translated into furniture designs characterized by flowing curves and high-end brass bases. Our pieces present a neoclassical style that is elegant, modern, and built to last. Our work is suited for modern hotel dining spaces, historic residences, and high-end commercial spaces worldwide.
