Hot Rolled Flat Bars
Hot Rolled Flat Bars
Hot Rolled Flat Bars are used for general purpose applications across construction, fabrication, and industrial maintenance.
- A36 (UNS K02600)
- Low-carbon steel
- Hot-rolled, mill finish
- Excellent weldability
Overview
Hot Rolled Flat Bars are fundamental steel products essential for a vast range of general fabrication, construction, and industrial maintenance projects. As a premier metal supply in Los Angeles, we provide high-quality hot rolled flats that serve as the backbone for structural frameworks, machinery bases, brackets, and countless other applications. These versatile bars are produced through a hot rolling process at high temperatures, resulting in a product that is easier to form and weld compared to cold-finished steel.
Our inventory includes hot rolled flat bars compliant with ASTM A36 and A569 standards, ensuring consistent quality and performance. The A36 grade is typically rolled as discrete bars, offering excellent weldability and strength for structural components. The A569 grade, often stripped from coil, provides a cost-effective solution for non-critical applications where precise tolerances are less crucial. This makes them an ideal choice for projects requiring reliable galvanized steel roofing supports, robust frames using square tubing or C channel, and durable bases for equipment.
For contractors, fabricators, and manufacturers throughout Los Angeles, our hot rolled flat bars offer exceptional value. They are commonly used in the construction of agricultural implements, transportation equipment, and as a key metal for construction projects. Their adaptability allows them to be easily cut, drilled, and welded on-site, speeding up project timelines. Whether you need standard mill lengths or custom cut-to-size pieces for specific requirements like B-deck installation or fence post fabrication, we offer flexible sourcing options. Partner with a trusted Los Angeles metal supply for all your hot rolled flat bar needs, from large-scale industrial orders to precise custom fabrications involving diamond plate or sheet metal components.

How to Measure
Specify Thickness (in inches or gauge), Width (in inches), and Length (in feet/inches). For custom cuts, provide exact length requirements. Standard tolerance for cutting is 1/8". Material is sold by weight (pounds). Use standard steel density (0.283 lbs/in?) for calculations. When ordering, specify ASTM grade (A36 or A569) and desired finish (e.g., HR, HRPO).
Order Checklist
- Thickness, Width, and required length (e.g., 1/2" x 4" x 20')
- Grade (e.g., A36, A569) and quantity (pieces, feet, or pounds)
- Cutting instructions (standard 20' lengths or custom cuts with tolerance)
- Surface finish requirements (as-rolled, HRPO, cleaned)
- Any certifications (Mill Test Report - MTR) required
- Special handling, packaging, or delivery requirements
