"flat" usually refers to flat steel
Specifically, "flat" in steel mainly refers to steel products with the following characteristics:
1.Flat shape: This is the most core feature. It refers to the cross-section of the steel being approximately rectangular (rectangular), and the width (or diameter, but mainly width) being much greater than the thickness (height).2.rolled edge: The edge of flat steel is usually a naturally rolled edge (rolled edge), unlike mechanically processed plates which have sharp right angles or bevels. This edge can be a very slight inner fillet (such as in hot-rolled flat steel) or relatively sharper (such as in some precision cold-rolled flat steel).
3.Typical product: The description "Flat" is often used for:
Flat Bar: This is the most common name.
Coil or Strip: Essentially, they are very long flat steel coiled up and also fall under the category of "flat".
Plate and Sheet: In a broad sense, they are also flat shapes, but the industry is more accustomed to directly referring to them as "plate" and "sheet" because they are usually large-sized flat plates and their edges may undergo further processing (shearing, flame cutting, etc.). So in daily conversations, when "flat" is said, it often refers not to plates but to flat steel or steel strips in the form of strips.
4.Production method: Mainly produced through hot rolling or cold rolling processes.Main features and uses:
Wide size range: Thickness (usually ranging from a few millimeters to tens of millimeters) and width (usually ranging from tens of millimeters to hundreds of millimeters) can vary greatly.Wide range of applications:
Due to its simple shape and ease of processing (bending, welding, punching, etc.), flat steel is one of the most fundamental and commonly used types of steel.
Common uses include:
- Building structure (supports, frames, connectors)
- Mechanical manufacturing (machine bases, parts)
- Vehicle manufacturing (trailer chassis, components)
- Tool manufacturing (support for shovels and spades)
- Raw materials (steel strips) used for the production of welded pipes and cold-formed steel sections
- Fence, enclosure
- Daily hardware
The difference from related terms:
- Plate (thick plate/medium plate) /Sheet (thin plate) : It places more emphasis on large, flat steel sheets. Although they are flat in shape, they are generally not directly referred to as "flat".
- Bar (bar) : This is a broad term referring to all long strip-shaped steel materials. The bars include Flat Bar, as well as Square Bar, Round Bar, Angle Bar, Hex Bar, I-Beam, etc. So, "Flat Bar" is a specific shape of Bar.
- Long Products: Refer to the bar steel that needs to be produced through die rolling (hot rolling), including reinforcing bars, wire rods, bars (round steel, square steel, flat steel, Angle steel, etc.), rails, section steel, etc. "Flat Bar" belongs to a kind of long materials.
- Flat Products: Refer to steel products produced through Plate /Strip rolling mills, mainly including plates, thin sheets, Coil/Strip. "Flat Bar" is sometimes broadly classified as flat material because of its flat shape, but it is more specifically categorized as a type of long material (bar).
Summary:
When "flat" is mentioned in steel, in the vast majority of cases, it refers to Flat Bar. This is a kind of long strip-shaped steel with a rectangular cross-section, a width much greater than the thickness, and a rolled edge. It is one of the most fundamental and widely used varieties of steel, and is extensively applied in multiple fields such as construction, machinery, and vehicle manufacturing.
