Cálculo de quilos por metro linear de barras retangulares:

L x Comprimento x Espessura x C =

L = Largura

C = Constante

Exemplo: Chapa nº20 / 1,00 m/m - 2 metros x 1 metro

L x Comprimento x Espessura x C = 1 x 2 x 1,00 x 7,93 = 15,86 kg

Exemplo Chapa nº14 / 2,00m/m - 3 metros x 1,2 metros

L x Comprimento x Espessura x C = 1,2 x 3 x2,00 x 7,93 = 57,10 kg
