TYPICAL ADVANTAGES
– Through a closed-loop manufacturing process at Vina One Steel factory, a high-quality galvanized pipe is formed progressively from galvanized steel coil. The process is actively controlled from the input raw material till the finished profile.
– Vina One cold rolled steel pipes have a good appearance and surface quality.
Meet the standards of sizes, dimensions, temperatures, pressures, also the thickness of galvanized layers.
– The steel features a reasonable level of strength and toughness so that it fits to the needs of customer on bending, flattening, and expanding processes.
– The products are packed and storaged under a strict procedure to ensure the goods are safer and less damaged when loading and transporting.
