Overview|Specifications|Applications|Finish Options|How to Measure|Order Checklist

Hot Rolled (HR) A36 Steel Flat Bar is formed at high temperatures, giving it a characteristic scaly, blue-grey mill finish and slightly rounded edges. This process results in a cost-effective material with good formability and outstanding weldability using all common methods. Its reliable strength and toughness make it a foundational material for construction and industrial fabrication.

As a medium-sized bar, this 3" width is highly versatile. It is an excellent choice for structural bracing in building frames, durable wear strips for machinery, strong base plates for equipment mounting, and general repair work where strength and weldability are key requirements for the component.
