Infra-Metals Co. is one of the largest structural steel service centers in the United States. We offer a comprehensive selection of carbon structural steel products for clients in diverse industries. From construction professionals to engineers, customers turn to us for beams and tubing, plates, angles, bars, channels/miscellaneous channels, pipes, sheets, and expanded metal products.
Structural steel has numerous applications, but it’s primarily found in buildings and bridges. In the United States, steel for such projects uses standard alloys specified and identified by the American Society for Testing and Materials (ASTM). This global organization establishes and publishes technical standards for materials, services, products, and systems. Its identification system starts with A, followed by two-four numbers.

Wide Flange Beams
Wide flange beams, or W-beams, are essential components in load-bearing structures such as bridges, buildings, and other large-scale infrastructure or civil engineering projects. Known for their parallel flange surfaces and broad dimensions, W-beams provide exceptional load distribution. They’re also resistant to bending. Wide flange beams offer great horizontal support in applications like steel frames as they minimize deflection.
Infra-Metals carries W-beams manufactured to ASTM A992 standards, among others, to best ensure an optimal strength-to-weight ratio, sufficient toughness, and exceptional weldability. We keep a wide selection of weights and sizes in stock to meet your exact structural and load requirements.
Structural Tubing
Infra-Metals provides structural tubing in round, square, and rectangular hollow structural sections (HSS). Used extensively in structural as well as architectural designs, HSS tubing combines sleek aesthetics with high torsional strength, compression resistance, and good weldability. It’s also relatively cost-effective, making it ideal for diverse applications.
Structural steel tubing is applicable for columns, framing, supports, and related uses in low- to mid-rise buildings. It’s particularly valued in seismic zones for its resilience. The tubes we carry conform to ASTM A500 Grades B and C. To allow for immediate tube use and fabrication upon delivery, Infra-Metals offers processing services like miter cutting and drilling in-house.
Plates
Supporting applications ranging from column base plates and construction machinery parts to bridge components and large welded structures, steel plates are known for their strength, durability, and versatility. At Infra-Metals, our selection of metal steel plates includes grades such as:
- ASTM A36: A standard structural carbon steel suitable for general use
- ASTM A572, Grades 50 and 55: Plates that provide increased strength but similar formability to A36
- ASTM A514: A quenched and tempered alloy with exceptional strength for applications in heavy transport machinery and crane booms
Angles
L-shaped steel angles have applications in everything from industrial and commercial construction projects to walkways and trailers. They transfer loads effectively and provide a simple solution for reinforcement and edge or corner support. These angles also play a key role in handling multi-directional stress.
Infra-Metals stocks steel angles and metal tube angles in equal and unequal leg styles to support our clients’ bracing, bracketing, framing, and shelving applications. These steel angles conform to ASTM A36 and A529 standards. As value-added services, our team performs notching, punching, and custom cutting in-house, playing an integral role in your fabrication workflow.
Merchant Bars
Ubiquitous in fabrication shops, merchant bar steel is a staple for base plates, mounting frames, support braces, machine parts, ornamental work, gates, and more. Merchant bars are frequently chosen for industrial, commercial, and non-standard projects due to their versatility.
Infra-Metals stocks merchant bars that meet ASTM A36 standards for their machinability and weldability. With a large selection of bar dimensions and shapes (flats, rounds, and squares) available, Infra-Metals will custom-cut or process your merchant bars per your specifications with quick turnaround times.
Structural Steel Channels
C-channels and miscellaneous channels (MC) are ideal for load-bearing applications covering short to average distances. Examples of common structural channel applications include frames and other building supports, roof trusses, platforms, stair stringers, and trailers. MC channels utilize additional material to deliver enhanced strength and structural capacity.
Infra-Metals carries structural steel channels in ASTM A36 and A572 grades and more. Choose from hot-rolled or cold-formed options based on your structural needs, weight requirements, and budget. With precision saw cutting capabilities, we ensure that each piece fits perfectly to save you valuable time making adjustments on-site.
I-Beams
Compared to W-beams, I-beams — also known as S-beams — have a narrower flange and are designed for lighter-duty structural uses. They are widely utilized in trailer frames as well as residential construction and staircases. Though they lack the strength of wide flange beams, I-beams deliver adequate strength for average loads, and all at a more affordable price.
Infra-Metals offers I-beams that meet ASTM A36 and A992 specifications. Our team also provides custom services like cambering and miter cutting to deliver job-ready materials processed to your exact specifications.
Pipes
Infra-Metals supplies structural steel pipes in both seamless and welded forms. These products accommodate mechanical and process systems; framing, columns, and other structural supports; railings; fencing; and more.
Our steel pipes conform to ASTM A53 standards for mechanical- or pressure-based applications and ASTM A500 standards for structural projects. We offer round structural pipe in various wall thicknesses and schedules, and you can select from beveled, threaded, and other end-finishing options as needed.
Sheets
Our steel sheet metal offerings include:
- Hot-rolled (HR) sheet: Lends strength to heavy-duty projects
- Cold-rolled (CR) sheet: Delivers tighter dimensional control and an impressive surface finish
- Galvanized sheet: Offers corrosion protection for outdoor or marine environments
Solar Panel Mounts
Steel for solar applications needs to withstand environmental extremes from desert heat to coastal moisture. With renewable energy initiatives on the rise, Infra-Metals distributes high-performance structural steel to support utility-scale and commercial solar panel mount and racking system projects.
Our galvanized steel channels and beams meet ASTM A653 requirements for corrosion resistance and longevity in outdoor settings. We work closely with solar fabricators and EPCs to supply material for racking systems, canopy structures, ground-mount arrays, and more. With fast turnaround and customizable lengths, we help keep solar projects on schedule and industry compliant.
