Flat Bar Weight Calculator

Hot-rolled flat steel, as specified by GB/T 702-2008 standard, comes in a wide range of dimensions to suit various industrial applications. The thickness typically spans from 3mm to 60mm, while the width ranges from 10mm to 200mm. These dimensions, along with the material’s density and length, are crucial factors in determining the weight of flat bars.

The delivery of hot-rolled flat steel can be based on either actual weight or theoretical weight, depending on market specifications and customer requirements. Actual weight accounts for real-world variations in production, while theoretical weight is calculated using nominal dimensions and standard density.

To assist in precise material estimation and cost calculation, we provide a convenient flat bar weight calculator below. This tool uses the density of steel (typically 7.85 g/cm³ for carbon steel) and your input dimensions to compute the weight of the flat bar accurately.

When using this calculator, keep in mind the following:

1. Input dimensions in millimeters (mm) for thickness and width, and meters (m) for length.
2. The calculator assumes a standard steel density. For specialized alloys, consult material specifications for precise density values.
3. Results are typically provided in kilograms (kg), but can be converted to other units as needed.
4. For large orders or critical applications, it’s advisable to factor in the allowable deviation specified by GB/T 702-2008 to ensure accurate material planning.

Understanding the weight of flat bars is essential for various aspects of metal fabrication, including material procurement, transportation logistics, structural load calculations, and cost estimation. This calculator serves as a valuable tool for engineers, fabricators, and project managers in the metal working industry.

What is flat bar?

Flat bar, also known as flat steel, is a versatile structural steel product characterized by its rectangular cross-section with a width typically ranging from 12 to 300mm and a thickness between 3 and 60mm. The edges are slightly rounded to enhance safety and handling. This profile combines strength with a slim form factor, making it suitable for various applications in construction, manufacturing, and mechanical engineering.

Flat bar serves dual purposes in the metal industry:

1. As a finished product: It can be directly used in various applications without further processing.
2. As raw material: It serves as a base for manufacturing other products, such as welded pipes and thin slabs for laminated rolling.

Common applications of flat bar include:

• Structural components: Used in house framing, support beams, and bracing in construction projects.
• Mechanical parts: Employed in the fabrication of machine components, brackets, and fittings.
• Tools and equipment: Utilized in the production of hand tools, agricultural implements, and industrial machinery.
• Transportation: Found in the manufacturing of vehicle frames, trailer components, and railway equipment.
• Architectural elements: Incorporated into staircases, balustrades, and decorative features in buildings.
• Industrial applications: Used in the production of conveyor systems, material handling equipment, and storage racks.

The versatility of flat bar, combined with its strength-to-weight ratio and ease of fabrication, makes it a popular choice across various industries for both structural and aesthetic applications.
