Price range: $30.68 through $149.73

Part#: SFL3810 Category
DESCRIPTION

The 3/8″ × 10″ Steel Flat Bar is manufactured from A-36 hot-rolled carbon steel, produced to meet ASTM A36 specifications for structural and general fabrication applications. The bar features a 3/8-inch thickness and 10-inch width, offering a strong, flat, and versatile surface for a wide range of industrial, construction, and mechanical projects. Hot-rolled (HR) processing provides improved ductility, ease of welding, and excellent machinability, making this flat bar ideal for both structural and custom fabrication work.

Applications:
3/8″ × 10″ Steel Flat Bar A-36 HR is commonly used in:

  • Structural supports and framework for buildings and machinery
  • Brackets, braces, and equipment mounting
  • Industrial and construction fabrication projects
  • Tooling, bases, and heavy-duty machinery parts
  • General metalworking and welding projects
  • DIY and custom fabrication requiring strong, durable steel

Advantages:

  • High strength: A-36 steel has a minimum yield strength of 36,000 psi and tensile strength of 58,000–80,000 psi
  • Hot-rolled: Provides toughness, good ductility, and weldability
  • Versatile sizing: 3/8″ × 10″ cross-section is suitable for both small and large structural projects
  • Durable: Resistant to wear and deformation under standard loads
  • Easy to fabricate: Can be cut, drilled, welded, and machined to suit project needs

Summary:
The 3/8″ × 10″ Steel Flat Bar A-36 HR is a robust, versatile, and durable material designed for structural, industrial, and general fabrication applications. Its hot-rolled construction, strong mechanical properties, and adaptability make it an ideal choice for frameworks, supports, brackets, and custom metalworking projects requiring reliable performance.

* Prices are subject to change without notice due to fluctuations in the metals market. | All “Value Length” and “Value Pack” item measurements are subject to standard mill tolerances. | Products may be manufactured several thousandths of an inch over or under the stated dimensions and still be within acceptable mill tolerances. All bar, tube, structural, pipe, sheet, plate, and similar products sold on our website are custom cut to the lengths and sizes selected by the customer at the time of purchase. These are not stocked as pre-cut items. Because each order is cut specifically to customer specifications, all cut materials are considered custom products and are not eligible for cancellation, return, or exchange once production has begun. Our standard cutting tolerances are:

  • Length: +0.125″ / -0.062″
  • During the cutting process, the saw blade removes approximately 1/16″ (kerf) of material. This is a normal part of the manufacturing process and is already included within the stated cutting tolerances.
