- Round drawn bars – made of steel in grades 1 to 8, delivered to the customer in hardened, softened, normalized or tempered condition. They have different dimensions and lengths.
- Square drawn bars – made of steel in grades 3 to 12, delivered to the customer in hardened, softened or tempered condition. They have different dimensions and lengths.
- Hexagonal drawn bars – made of steel in class 1 to 6, delivered to the customer in hardened, softened or tempered condition. They have different dimensions and lengths.
- Flat drawn bars – made of steel in class 1 to 5, delivered to the customer in hardened or softened condition. They have different dimensions and lengths.
