En comparación con las barras sólidas, las secciones huecas ofrecen una relación resistencia/peso superior, lo que permite diseños estructurales más ligeros y económicos. Con superficies lisas, tolerancias dimensionales precisas y excelente soldabilidad, nuestros tubos de acero cuadrados y rectangulares se adaptan a una amplia gama de aplicaciones estructurales y mecánicas. Ofrecemos tamaños SHS de 10 × 10mm a 500 × 500mm, tamaños RHS de 10 × 20mm a 600 × 400mm, espesores de pared personalizables de 0,5-40,0mm y longitudes de hasta 18 metros. Múltiples acabados superficiales incluyendo laminado en caliente, laminado en frío y galvanizado en caliente están disponibles.

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 los tubos de acero cuadrados y rectangulares se fabrican en estricta conformidad con los estándares oficiales de la industria y se someten a pruebas sistemáticas exhaustivas antes del envío, lo que garantiza cero defectos potenciales y una integridad estructural completa para uso industrial.
Ensayo de tracciónSe implementa como un procedimiento obligatorio de inspección completa. Esta prueba de núcleo verifica que cada tubería terminada cumple completamente con los requisitos de especificación para el límite elástico, la resistencia a la tracción y el alargamiento.
Aplanamiento de la pruebaAsegura la ductilidad y la calidad de soldadura de sonido del producto terminado.
Análisis de composición químicaGarantiza la pureza del material y el cumplimiento de las especificaciones de grado.

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 los tubos de acero cuadrados y rectangulares se fabrican en estricta conformidad con los estándares oficiales de la industria y se someten a pruebas sistemáticas exhaustivas antes del envío, lo que garantiza cero defectos potenciales y una integridad estructural completa para uso industrial.
Ensayo de tracciónSe implementa como un procedimiento obligatorio de inspección completa. Esta prueba de núcleo verifica que cada tubería terminada cumple completamente con los requisitos de especificación para el límite elástico, la resistencia a la tracción y el alargamiento.
Aplanamiento de la pruebaAsegura la ductilidad y la calidad de soldadura de sonido del producto terminado.
Análisis de composición químicaGarantiza la pureza del material y el cumplimiento de las especificaciones de grado.
