Klasifikacija čelične žice

Prema obliku poprečnog presjeka, žice se dijele na okrugle, kvadratne, pravougaone, trouglaste, eliptične, ravne, trapezoidne i Z{1}} oblike. Po veličini žice se dijele na ekstra{3}}fine (<0.1 mm), thin (0.1-0.5 mm), thin (0.5-1.5 mm), medium (1.5-3.0 mm), thick (3.0-6.0 mm), thick (6.0-8.0 mm), and extra-thick (>8,0 mm). Prema jačini, žice se dijele na niske-jače (<390 MPa), low-strength (390-785 MPa), standard-strength (785-1225 MPa), high-strength (1225-1960 MPa), high-strength (1960-3135 MPa), and extra-high-strength (>3135 MPa).
