Brass Tubing

Lewis Brass & Copper focuses heavily on copper-based alloys, with a large inventory of brass tubing, architectural bronze tubing, copper pipe, ornamental profiles, and custom sizing support for industrial and architectural applications.

 

Common Types of Metal Tubing

Common Forms of Metal Tubing

Different types of metal tubing are designed around different application requirements and end-use environments rather than a single performance standard.

 

Round, Square, and Rectangular Tubing

Round tubing remains one of the most widely specified forms across industrial metal tubing applications because it performs well in bending, forming, and fluid-related systems. Square and rectangular profiles are often selected when alignment or structural stability carry greater importance. In commercial applications, square and rectangular tubing can also simplify attachment points because flat surfaces reduce the need for secondary fitting work.

Common uses for round metal tubing include:

  • Handrail systems
  • Architectural framework and components
  • Heat exchangers
  • Mechanical assemblies
  • Instrument components
  • Fluid-transfer systems

Square metal tubing is frequently specified for:

  • Architectural framing
  • Equipment supports
  • Furniture manufacturing
  • Commercial interiors
  • Structural reinforcement

Rectangular tubing is often used where designers need:

  • Greater directional rigidity
  • Tighter installation clearances
  • Flat mounting surfaces
  • Longer unsupported spans
  • Cleaner linear aesthetics

Lewis Brass & Copper stocks round, square, and rectangular tubing in various alloys including brass, bronze and copper.

 

Ornamental Tubing

Ornamental tubing introduces additional surface detail or profile geometry for exposed architectural installations. Unlike purely mechanical tubing, ornamental profiles often require tighter cosmetic consistency because the finished surface remains visible after installation. These products are widely used in hospitality interiors, railing systems, elevator detailing, furniture components, and decorative metalwork.

Lewis Brass & Copper stocks ornamental profiles including:

  • Round reeded tubing
  • Roped tubing
  • Hexagonal tubing

 

Seamless and Welded Tubing

Seamless metal tubing is manufactured without a welded seam, which can make it advantageous in applications involving higher pressures, tighter tolerances, or more demanding mechanical conditions. Welded tubing may offer advantages in cost, availability, and architectural finishing applications.

Brass Tubing

Brass tubing remains one of the most versatile copper-alloy tubing categories because it machines efficiently while still maintaining good formability and appearance quality.

Common brass tubing applications include:

  • Handrail systems
  • HVAC supports and fixtures
  • Furniture manufacturing
  • Lighting components
  • Mechanical assemblies

Lewis Brass & Copper is known as a brass tubing specialist and maintains a large inventory of round, square, rectangular, and ornamental brass tube products.

Bronze Tubing

Bronze tubing is a broader category of copper-alloy tubing associated with higher wear resistance, corrosion performance, and durability in demanding operating conditions. True bronze alloys are commonly specified for:

  • Bushings and bearings
  • Industrial wear components
  • Demanding mechanical assemblies
  • High-corrosion environments

Compared to many standard brass alloys, bronze materials are often selected when the application places heavier demands on strength, abrasion resistance, or environmental exposure.

 

Architectural Bronze Tubing

Lewis Brass & Copper stocks architectural bronze tubing products used in commercial and decorative architectural applications. These products are commonly manufactured from CDA 385, a brass-based alloy widely used in commercial and decorative metalwork applications, including:

  • Railing systems
  • Decorative framing
  • Exposed architectural metalwork
  • Furniture components
  • Hospitality interiors

We stock round, square, and rectangular architectural bronze tubing profiles for projects that emphasize finish quality and appearance consistency in addition to long-term material performance.

 

Copper Tubing

Copper tubing continues to play an important role across electrical, HVAC, plumbing, and heat-transfer systems because of its conductivity and corrosion resistance.

In many industrial applications, copper tubing selection is tied closely to conductivity requirements, joining methods, operating temperatures, and long-term environmental exposure.

Choosing the Right Metal Tubing Supplier

Tubing procurement problems do not always begin with the alloy specification. Delays often appear later through inconsistent inventory, limited processing support, poor packaging, or unreliable fulfillment schedules.

Experienced buyers normally look for suppliers that can support both technical and operational requirements, including:

  • ASTM compliance and material certifications
  • Consistent inventory availability
  • Custom sizing and processing support
  • Alloy-selection guidance
  • Reliable lead times and logistics support

Lewis Brass & Copper maintains more than one million pounds of inventory and supports customers with alloy-selection assistance and custom sourcing. Explore our full tubing and pipes collection to find the right material for your next industrial or architectural project.
