Ratna Exports is one of the renowned manufacturers and exporters of Corten Steel Square Tubes that have the quality of not only being corrosion-resistant but also durable in harsh conditions. The tubes are weathered steel that produces a stable rust-like visual effect and although it strengthens the looks of the tubes, it also helps protect them naturally against environmental effects.
They are on different grades without exception and are specifically processed. Ranging between CORTEN A, CORTEN B, ASTM A588, ASTM A847, S355JOW, S355J2W, S355JOWP and S355J2WP, A709-50W, Sailcor, among others, they are all designed to meet your projects requirements. Depending on your requirements in terms of thickness, length and surface finish we can supply high precision products with short delivery times.
The square tubes are perfect in severe outdoor environments. After getting into contact with moisture and air the steel forms a protective patina that removes the necessity to paint or coat the surface. This leads to cheaper costs on maintenance and increased strengthening of them thus they are a better option when it comes to many sector applications.
Ratna Exports maintains a ready stock of Corten Steel Pipes, Tubes in multiple sizes to fulfil urgent or bulk orders. We ensure timely delivery in secure, standard packaging to both domestic and international customers. With competitive pricing and responsive service, we are a preferred supplier across industries.
