Great experience working with this factory. They have a wide range of standard sizes and can adjust specifications to match our local construction codes. The stainless steel material is solid, perfect for our outdoor fence in hot weather. Communication was smooth, production schedule kept well.

Hemos usado el tubo cuadrado de acero inoxidable 120x120mm pared gruesa de Winsco Metal para la estructura de barandillas de un centro comercial en Lima. Disponemos de grados SUS201, AISI304 y TP316 para elegir según el ambiente de obra. Los bordes están bien cortados, las dimensiones perfectas y la estructura muy robusta. Resiste muy bien la salinidad de nuestra costa. Todos los certificados fueron entregados rápidamente. Es nuestro proveedor favorito para proyectos de edificación.
