Tubos Estruturais Quadrados

Tabela das 193 bitolas de tubo estrutural de seção quadrada (b x b), laminados a quente pela Vallourec Tubos do Brasil (Usina Barreiro), de 50 x 50 a 300 x 300 mm. Fabricação conforme ABNT NBR 8261, que também define graus de aço, tolerâncias dimensionais e regra de designação.

Por simetria da seção quadrada, Ix = Iy, Wx = Wy, Zx = Zy e rx = ry — publicados numa coluna só por eixo, como nas cantoneiras e nos tubos circulares.

Verificado em 09/08/2026 · 2 fontes cruzadas

Fontes: Catálogo "Tubos Estruturais, Seção Circular, Quadrada e Retangular" — Vallourec & Sumitomo Tubos do Brasil, Usina Barreiro · ABNT NBR 8261:2019 — Tubos de aço-carbono, com e sem solda, de seção circular, quadrada ou retangular para usos estruturais

Método: Extração via pdfplumber (find_tables + extract_tables) da seção "Seção Tubular Quadrada (TQ)" (5 páginas), originalmente combinada com a retangular numa única tabela e separada em 09/08/2026 a pedido do Lorde — sem nova transcrição, só filtro das linhas onde a dimensão é um quadrado (b x b) e descarte das colunas Y (idênticas às X por simetria, conferido nas 193 linhas). A dimensão externa e a coluna U são células mescladas, centradas no grupo de espessuras, e por isso não alinham com nenhuma linha da grade extraída — foram recuperadas casando a posição vertical de cada rótulo (via extract_words) com o centro de cada linha de dado. Conferido por amostragem visual (menor e maior bitola) contra o render das páginas do catálogo original.

Legenda

Símbolo	Significado
b x b	Dimensões externas — lado do quadrado
d	Lado do quadrado (mesma medida de b x b, em coluna numérica separada)
e	Espessura da parede
Ix, Iy	Momento de inércia em relação aos eixos X-X e Y-Y (iguais por simetria)
Wx, Wy	Módulo de resistência elástico — eixos X-X e Y-Y (iguais por simetria)
Zx, Zy	Módulo de resistência plástico — eixos X-X e Y-Y (iguais por simetria)
rx, ry	Raio de giração — eixos X-X e Y-Y (iguais por simetria)
J	Constante de torção
Wt	Módulo de resistência à torção
U	Área de superfície (pintura) por metro linear
Disponibilidade	“Sob consulta” = bitola fora da linha regular, fabricada mediante consulta prévia ao fabricante

Como usar esta tabela

• Filtrar — digite parte da dimensão (100 x 100) para restringir a lista.
• Filtrar por coluna — clique no funil de qualquer cabeçalho: marque/desmarque valores, busque na lista ou ordene A→Z / Z→A, como no Excel.
• Ordenar — clique no cabeçalho de qualquer coluna. Ordena corretamente número em formato brasileiro.
• CSV — marque até 5 linhas na primeira coluna e baixe o CSV somente delas (acentuação correta no Excel).
• Expandir — remove o limite de altura da tabela, eliminando a rolagem interna.

“Sob consulta” não é erro de dado

Bitolas marcadas na coluna “Disponibilidade” existem no catálogo do fabricante, mas fora da linha de produção regular — confirmar prazo e quantidade mínima antes de especificar em projeto. As demais bitolas são de fabricação frequente.

Grau do aço, tolerâncias e designação

Esta página cobre só as dimensões e propriedades geométricas. Composição química, limite de escoamento por grau (A/B/C), tolerâncias dimensionais e a regra de designação da NBR 8261 estão na página Normas.

A fazer nesta página

• Desenho da seção com cotas (d, e) — reaproveita o mecanismo interativo já usado na Cantoneira L
