* Qualquer bitola fora desta tabela é fabricada somente sob consulta à Engenharia.
Como verificar a fabricação de um tubo retangular:
Exemplo 1 — R 35 × 45 × 2,65: o lado 35 mm é fabricado com espessura 2,65 mm e o lado 45 mm também. Portanto, fabricado normalmente.
Exemplo 2 — R 35 × 45 × 4,25: o lado 35 mm não é fabricado com espessura 4,25 mm (fora da faixa para L ≤ 40), embora o lado 45 mm seja. Portanto, consulta à Engenharia necessária.
