Steel Beam Suppliers
When a project depends on dependable structure and consistent material quality, the right steel supplier makes all the difference. Contractors, fabrication shops, and industrial teams across the region rely on Service Steel & Pipe for steel beams that arrive on spec, on time, and withstand demanding environments.
Our inventory covers a broad range of wide flange beams, standard I-beams, and M/JR/S beams, with many sizes available in long lengths to support structural, industrial, and fabrication work.
Whether you’re framing a commercial building, reinforcing an industrial facility, or supporting machinery and material-handling systems, our team can help you source the beam profile that matches your project requirements.
Wide Flange Beam Supplier
Wide flange beams offer strength and stability across long spans, making them a standard choice for heavy structural work. Their broad flanges help distribute loads efficiently, which makes these sections useful for large buildings, platforms, bridges, equipment supports, and other load-bearing structures.
Engineers and fabricators regularly specify wide flange beams because their shape performs predictably under bending, compression, and tension while providing substantial connection surfaces for plates, brackets, and other structural members.
Available Grades, Lengths & Sizes
Service Steel & Pipe supplies beams manufactured to recognized structural standards, including:
- A-992
- ASTM A-36
- A-572 Grade 50
Most sizes are available in long lengths, helping contractors and fabricators reduce field splicing and unnecessary material handling.
Wide flange inventory includes profiles such as:
- 4" to 36" nominal sizes
- Depths from approximately 4.1" to more than 37"
- Flange widths from approximately 4" to more than 16"
- Web thicknesses beginning around 0.23" and increasing with heavier sections
- Weights from approximately 13 lb/ft to well over 350 lb/ft
Detailed dimensions and weights are available through the Service Steel & Pipe product catalog so buyers can compare sections before ordering.
Where Wide Flange Beams Are Commonly Used
Wide flange beams are commonly selected for structures where span length, rigidity, and load capacity are major considerations.
- Commercial and industrial building frames
- Bridges and overpasses
- Crane runway systems
- Equipment supports and mezzanines
- Large-scale fabrication projects
Builders often select these sections when a project requires long spans without excessive intermediate bracing or when the structure must support substantial static or dynamic loads.
Standard I-Beam Supplier
Standard I-beams, sometimes called S-beams or rolled I-beams, use a narrower flange profile than many wide flange sections. Their shape makes them a practical choice for structural and fabrication applications where strength is required but the broader flange of a wide flange beam is not necessary.
Fabricators frequently use I-beams for general framing, machinery supports, skids, platforms, and other assemblies that require a rigid load-bearing member.
Sizes & Specifications Available
Service Steel & Pipe stocks ASTM A-36 and dual-certified A-36/A-572 I-beams in a range of dimensions.
- 3" to 24" nominal sizes
- Depths from 3" to more than 25"
- Flange widths from roughly 2.3" to 8"
- Web thicknesses from approximately 0.170" to 0.800"
- Weights between approximately 5.7 lb/ft and 121 lb/ft
Beam lengths shown in the catalog include 20-foot, 40-foot, and 60-foot options, giving buyers flexibility when planning shorter assemblies or extended structural spans.
Typical Uses for Standard I-Beams
- General-purpose structural framing
- Industrial conveyor bases and equipment skids
- Trailer and platform construction
- Support beams for mezzanines and catwalks
- Renovation and retrofit work
Standard I-beams can provide a useful balance between structural strength, manageable weight, and ease of fabrication when a project does not require the wider load distribution of a wide flange section.
M or JR. Beam Supplier
M-beams, often grouped with miscellaneous or junior beam profiles, fill the gap between lighter structural shapes and heavier beam sections. Their proportions vary by size, making them useful when a design calls for a particular depth, flange width, or weight that does not match a standard I-beam profile.
These sections provide structural support with a comparatively compact profile and are commonly considered for lighter framing and fabricated assemblies.
Dimensions & Grades Stocked
According to the Service Steel & Pipe product catalog, M / JR. beams are available in:
- ASTM A-36
- A-572 Grade 50
Nominal sizes generally include 6", 8", 10", and 12" sections. Typical dimensional ranges include:
- Depths from 6" to 12"
- Flange widths from approximately 1.8" to 3.1"
- Web thicknesses between approximately 0.114" and 0.177"
- Weights from approximately 4.4 lb/ft to 11.8 lb/ft
Where M / JR. Beams Are Used
- Light structural supports
- Agricultural buildings
- Trailer manufacturing
- Equipment stands
- Maintenance and repair applications
Their lighter weight can make these sections easier to handle during fabrication and installation while still providing rigidity for smaller structural systems.
Why Builders Work With Service Steel & Pipe
Choosing the correct beam profile is only part of the purchasing process. Contractors and fabricators also need material availability, processing support, and delivery coordination that fits the project schedule.
Customers work with Service Steel & Pipe for several practical reasons:
- Large, ready-to-ship inventory of structural steel products
- Multiple beam sizes and profiles available
- Material support for both small orders and larger-volume requirements
- Processing services that can reduce jobsite cutting
- Regional delivery support for qualifying commercial and industrial orders
Service Steel & Pipe has served the Shreveport and ArkLaTex metals market since 1975. You can read more about the company’s history and regional operations.
Delivery, Handling & Processing
Many steel beam orders require more than simply pulling stock from inventory. Long structural members may need sawing, careful handling, staging, and delivery coordination before they reach the fabrication shop or jobsite.
Service Steel & Pipe supports beam orders with:
- Sawing to Length: Material can be prepared to specified lengths for qualifying orders.
- Commercial Delivery: Delivery is available within the company’s regional service area for orders meeting applicable requirements.
- Heavy Material Handling: Large and long beam sections can be staged for pickup or shipment.
- Will-Call Pickup: Customers can coordinate material pickup from the Shreveport facility.
The company’s Services page provides more information about current sawing, shearing, plate burning, and delivery capabilities.
Industries We Serve
Steel beams are used across a wide range of construction, industrial, and manufacturing operations. Service Steel & Pipe supplies customers working in:
