Furniture Brass Tubes

Product Overview

Furniture Brass Tubes supplied by R V Metal Corporation are precision-manufactured decorative and structural brass tubes designed specifically for premium furniture, interior décor, architectural elements, and lighting fixtures. Produced from high-quality brass alloys such as CuZn30 and CuZn37, these tubes offer an excellent balance of strength, formability, corrosion resistance, and surface finish, making them ideal for visible applications where aesthetics and durability are equally critical.

Our furniture brass tubes are available in round, square, rectangular, and custom profiles with tight dimensional tolerances and consistent wall thickness, ensuring uniform appearance and reliable fabrication. The material supports bending, cutting, drilling, welding, brazing, polishing, and surface treatments without cracking or distortion, allowing designers and fabricators complete flexibility in modern and classic furniture designs.

R V Metal Corporation offers these brass tubes in multiple tempers and finish-ready conditions, suitable for mirror polish, satin, brushed, antique, lacquered, PVD-coated, or powder-coated finishes. Widely used in luxury furniture frames, table bases, chairs, wardrobes, partitions, handrails, lighting fixtures, and decorative architectural elements, our furniture brass tubes meet international quality expectations for both domestic and export markets.
