Flat Bar Sizes
Carbon Steel Flat Bar is normally purchased according to width × thickness × length.
Typical inquiry information includes:
- Flat bar width
- Thickness
- Length
- Steel grade
- Standard
- Quantity
A simple inquiry can be provided as:
Width × Thickness × Length + Grade + Quantity
For example, buyers can send a complete list of different flat bar sizes for CXYS to check as one order.
Standard lengths such as 6 m and 12 m are commonly requested. Cut-to-length supply can also be arranged according to the order.
Flat Bar Surface & Delivery Condition
Carbon Steel Flat Bar can be supplied in different conditions according to the grade, dimensions, and intended application.
Common options include:
