Klassifikazzjoni tal-Wajer tal-Azzar

B'forma ta' sezzjoni trasversali-, il-wajers huma kklassifikati f'forom tondi, kwadri, rettangolari, trijangolari, ellittiċi, ċatti, trapezojdali, u forma ta' Z-. Skont id-daqs, il-wajers huma kklassifikati fi -multa żejda (<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). Skont is-saħħa, il-wajers huma kklassifikati f'-saħħa baxxa (<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).
