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.

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.

Como usar esta tabela
Seção intitulada “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.
