Industrial-grade Metallurgy, High-end CNC Machining, and Classic Neoclassical Aesthetics Compliant with CTE and UNE European Directives.
Custom brass, copper, and bronze solutions calibrated for prestigious Spanish residential and commercial developments.
The demand for premium copper casting and alloy processing in Spain has shifted profoundly towards specialized, high-grade fabrications. From the industrial hubs of Catalonia, the Basque Country, and Madrid, to the luxury hospitality properties throughout Barcelona and Costa del Sol, engineering and design specifications require adherence to rigorous European norms. Under the Spanish Technical Building Code (Código Técnico de la Edificación - CTE), copper components used in plumbing, structural installations, and interior ornamentation must meet stringent anti-corrosion and mechanical endurance thresholds.
Globally, purchasing departments require high supply chain resilience, transparent raw material traceabilities, and precise quality certificates. The Spanish market, in particular, values manufacturers capable of matching high-end aesthetic value (such as neoclassical art and retro finish styles) with robust mechanical performances. With rising logistical complexity across the EU, establishing a direct connection with an agile manufacturer like Buterfloge ensures smooth transit, strict adherence to UNE-EN standards, and comprehensive localized support.
All copper and brass castings are verified under strict European standards for tensile strength, dezincification resistance, and environmental sanitation compatibility.
Through advanced refining techniques, we reduce microstructure defects to less than 0.05%, guaranteeing flawless surface finishes and longevity under coastal maritime atmospheric conditions.
Our proprietary alloy formulas ensure structural longevity and aesthetic perfection across commercial projects.

Founder Rona Chu loves classic antique bathroom designs and shabby chic home styles. Dedicated to depicting a woman in 1980s slip dresses enjoying nature and revealing grace, noble flowers carry curves and a toned song for the flowers. We are always decent, confident and charming and go after what we think is worth it.
At Buterfloge, we translate this romantic, classical narrative into precise, durable metallurgical engineering. We blend the high artistic value of classical European styling with advanced CNC precision machining from our manufacturing facilities in Guangdong. This combination ensures that every brass hanger, decorative sculpture, or sanitary fixture represents a perfect symbiosis of design heritage and industrial excellence.
Ensuring seamless logistical pipelines and total regulatory alignment for Spanish importers.
Our direct logistical corridors to ports like Barcelona, Valencia, and Bilbao ensure reliable lead times and predictable customs clearance workflows.
All copper alloy selections undergo heavy metal leaching assessments, aligning with Directive (EU) 2020/2184 on water quality for human consumption.
Our in-house design team collaborates with Spanish architectural studios to refine CAD specifications before casting commences.
Clarifying technical and mechanical specifications for project engineering teams.
Every casting batch undergoes optical emission spectrometry (OES) analysis before leaving our facility in Guangdong. We verify that the levels of copper, zinc, tin, and lead correspond precisely with UNE-EN 1982 guidelines. Each order includes a material test report (MTR) detailing chemical analysis and mechanical values.
For installations in Mediterranean maritime zones (such as Malaga, Valencia, and Ibiza), we offer specialized PVD (Physical Vapor Deposition) and electrophoretic coatings. These layers provide salt spray test endurance exceeding 480 hours, protecting against high ambient humidity and salt exposure.
Yes. To comply with modern green building standards (such as LEED or BREEAM) and local Spanish municipal ordinances, we offer lead-free copper alloy grades (Pb < 0.1%). We replace lead with bismuth or silicon to preserve mechanical workability while ensuring safe municipal water integration.
For custom ODM/OEM designs, our typical MOQ starts at 100 units per item. Our sample development phase runs from 10 to 15 days, followed by 30 days for mass production. Shipping to Spanish ports typically takes 30-35 days, supported by complete customs documents and HS code classifications.
