ERW Steel Tube
ERW Steel Tube adalah jenis tabung baja yang dibuat menggunakan metode Electric Resistance Welding (ERW). Proses ini melibatkan pengelasan baja dengan pemanasan menggunakan arus listrik sehingga menghasilkan sambungan las yang kuat dan tahan lama.
Fungsi dari ERW Steel Tube adalah sebagai saluran untuk mengalirkan berbagai jenis fluida, seperti gas dan cairan, dalam berbagai aplikasi industri dan konstruksi. Tabung baja ini juga digunakan sebagai komponen struktural dalam berbagai proyek konstruksi, seperti tiang penyangga, rel, dan kerangka bangunan.
