Em comparação com as barras sólidas, as seções ocas oferecem relações força-peso superiores, permitindo projetos estruturais mais leves e econômicos. Com superfícies lisas, tolerâncias dimensionais precisas e excelente soldabilidade, nossos tubos de aço quadrados e retangulares se adaptam a uma ampla gama de aplicações estruturais e mecânicas. Oferecemos tamanhos SHS de 10 × 10mm a 500 × 500mm, tamanhos RHS de 10 × 20mm a 600 × 400mm, espessuras de parede personalizáveis de 0,5-40,0mm e comprimentos de até 18 metros. Vários acabamentos de superfície, incluindo laminados a quente, laminados a frio e galvanizados a quente, estão disponíveis.

Below are standard technical tables for square and rectangular steel pipes, covering chemical composition and tensile mechanical properties. All data complies with ASTM and EN standards for each steel grade. Chemical composition defines element content ranges to guarantee weldability, formability, and material purity. Tensile data shows standardized strength and elongation values, ensuring reliable mechanical performance, structural integrity, and load-bearing capacity. All technical indicators are traceable and support third-party inspection for industrial high-standard applications.

Todos os tubos de aço quadrados e retangulares são fabricados em estrita conformidade com os padrões oficiais da indústria e passam por testes sistemáticos abrangentes antes do envio, garantindo zero defeitos potenciais e integridade estrutural completa para uso industrial.
Teste elásticoÉ implementado como um procedimento obrigatório de inspeção completa. Este teste de núcleo verifica se cada tubo acabado atende plenamente aos requisitos de especificação de resistência ao escoamento, resistência à tração e alongamento.
Ensaio achatamentoAssegura a ductilidade e a qualidade da solda sadia do produto acabado.
Composição química AnáliseGarante a pureza do material e a conformidade com as especificações do grau.

Below are standard technical tables for square and rectangular steel pipes, covering chemical composition and tensile mechanical properties. All data complies with ASTM and EN standards for each steel grade. Chemical composition defines element content ranges to guarantee weldability, formability, and material purity. Tensile data shows standardized strength and elongation values, ensuring reliable mechanical performance, structural integrity, and load-bearing capacity. All technical indicators are traceable and support third-party inspection for industrial high-standard applications.

Todos os tubos de aço quadrados e retangulares são fabricados em estrita conformidade com os padrões oficiais da indústria e passam por testes sistemáticos abrangentes antes do envio, garantindo zero defeitos potenciais e integridade estrutural completa para uso industrial.
Teste elásticoÉ implementado como um procedimento obrigatório de inspeção completa. Este teste de núcleo verifica se cada tubo acabado atende plenamente aos requisitos de especificação de resistência ao escoamento, resistência à tração e alongamento.
Ensaio achatamentoAssegura a ductilidade e a qualidade da solda sadia do produto acabado.
Composição química AnáliseGarante a pureza do material e a conformidade com as especificações do grau.
