ASTM A283Gr.A,A283Gr.B,A283Gr.C,A283Gr.D flat steel

ASTM A283Gr.A,A283Gr.B,A283Gr.C,A283Gr.D flat steel used for machinery parts, mobile equipment, crane, boom, chassis, buildings, bridges and most structural activities.

ASTM A283 Standard Specification for Low and Intermediate Tensile Strength Carbon Steel Plates. ASTM A283Gr.A,A283Gr.B,A283Gr.C,A283Gr.D section steel is one of the four varieties(plates, tubes, profiles, wire) of steel.Based on cross-sectional shape,section steel is divided into simple section steel and complex section steel (profiled steel).the former refers to the square steel, round steel, flat steel, angle steel, hexagonal, etc.the latter refers to the beams, channels, rails, steel window frames, bent steel and so on.

ASTM A283Gr.A,A283Gr.B,A283Gr.C,A283Gr.D hot-rolled flat steel specification: Thickness--4mm-30mm Width--12mm-200mm Flat steel are divided into three groups by weight 1.Every m less than 19 kg,usually long 3 ~ 9 m (length). 2.Every m less than 19 ~ 60 kg,usually long 3 ~ 7 m (length). 3.Every m greater than 60 kg,usually long 3 ~ 5 m (length). Models for non-standard products, usually 2 ~ 6 m length
