Hot Rolled Squares
Hot Rolled Squares
Hot Rolled Squares are solid steel bars used for general purpose fabrication and structural applications. Manufactured from low-carbon steel with good mechanical properties, these bars feature radius corners from the hot-rolling process and are easy to fabricate using standard methods like welding, cutting, and machining.
- A36 (UNS K02600)
- Low-carbon steel
- Hot-rolled, mill finish
- Excellent weldability
Overview
Hot Rolled Squares are fundamental steel bar products essential for a vast range of general fabrication, construction, and manufacturing applications. Manufactured from low carbon steel, typically meeting ASTM A36 standards, these solid steel bars feature characteristic radius corners resulting from the hot rolling process. This production method ensures excellent overall mechanical properties, making the material exceptionally versatile and easy to work with using standard structural techniques like welding, cutting, hot forming, and machining. For businesses in Los Angeles seeking a reliable metal supply for projects involving structural supports, industrial maintenance, agricultural equipment, or ornamental ironwork, Hot Rolled Squares offer an ideal combination of strength, ductility, and cost-effectiveness. Their consistent quality and ease of fabrication make them a preferred choice for professionals working with various metal products. At our Los Angeles metal supply center, we stock a comprehensive range of sizes in ready-to-ship precut and mill lengths, and we offer custom cut-to-size services for both small and large quantity orders.

How to Measure
To specify a Hot Rolled Square:
- Side Dimension: Specify the length of one side (e.g., 1" x 1" square is called a "1-inch square").
- Length: Provide the required bar length in feet and inches.
- Grade: Typically ASTM A36.
- Quantity: Number of pieces or total linear feet needed.
- Finish: Standard is hot-rolled with mill scale. Specify if cleaned or other finish is required.
Measurement Tip: Measure across one flat side. The dimension is consistent on all four sides for a true square.
Order Checklist
- Size: Side dimension (e.g., 1.5")
- Grade: A36 or other specified grade
- Quantity: Number of bars or total linear feet
- Length: Desired length per piece (e.g., 10', 20', custom)
- Cutting Instructions: Tolerance, bundled, or individual
- Certifications: Mill Test Reports (MTRs) required (Yes/No)
- Surface Condition: As-rolled (mill scale) or other
