Brass Rectangular Tubes
Product Overview
Brass Rectangular Tubes manufactured and supplied by R V Metal Corporation are precision-engineered hollow sections produced from high-quality brass alloys, offering an ideal balance of strength, corrosion resistance, machinability, and aesthetic appeal. These tubes are widely used across architectural, decorative, electrical, plumbing, furniture, automotive, and general engineering applications where dimensional accuracy and surface finish are critical.
Our brass rectangular tubes are available in a wide range of sizes, wall thicknesses, and tempers to suit both structural and functional requirements. Manufactured using controlled extrusion and drawing processes, they ensure uniform wall thickness, tight dimensional tolerances, and consistent mechanical properties throughout the length.
Depending on application needs, the tubes can be supplied in free-cutting, high-strength, or corrosion-resistant brass grades, making them suitable for fabrication operations such as bending, drilling, threading, brazing, soldering, and polishing. Custom lengths, surface finishes, and alloy compositions can be provided on request to meet OEM-specific and project-specific requirements.
With strict quality control, mill test certificates (MTCs), and compliance with international standards, R V Metal Corporation’s brass rectangular tubes deliver reliable performance, long service life, and excellent value for industrial as well as decorative applications.
