Kereta ituGegelung Keluli Galvalume Panas unit memberi tumpuan kepada pengeluaran plat luar. Ketebalan spesifikasi produk kebanyakannya antara 0.6 dan 1.2mm, lebar plat kebanyakannya 800 hingga 1850mm, dan yang paling lebar boleh mencapai 2000mm. Tahap produk agak kompleks, daripada CQ, DQ, DDQ, EDDQ (IF) kepada BH, DP, TRIP dan plat keluli berkekuatan tinggi-automotif lain. Menggunakan pelbagai teknologi canggih, morfologi salutan dan ketepatan ketebalan boleh dikawal dengan tepat, seperti ralat ketebalan salutan kurang daripada 23g/m2. Tambahan pula, plat keluli bebas zink-boleh dihasilkan dengan menggunakan-pegalvani bebas plumbum. Salutan jenis ini tidak mudah menghasilkan kakisan antara butiran dan mempunyai hayat perkhidmatan yang panjang. Oleh itu, ia sesuai untuk industri automobil dan peralatan elektrik. Hampir setiap-unit galvani celup panas di Jepun dilengkapi dengan-relau mengaloi besi zink. Ketebalan lapisan tergalvani standard bagi plat aloi besi -zink (Galavneal) ialah 160180g/m2 pada kedua-dua belah dan salutan aloi mengandungi Fe8 peratus 12 peratus 2.
Foreign countries developed micro-alloy steel and phosphorous alloy steel in the 1970s, bidirectional DP steel and bake hardening steel in the mid-1980s, and phase transformation and induced plasticity TRIP steel in the 1990s 3. At present, the international cooperation project "Ultra-Lightweight Steel Carbody (ULSAB) Development" is proceeding smoothly. Its goal is to achieve a driving fuel consumption of 34KM/3L (US) and a car bodyweight reduction of 25 percent . The primary starting point is to adopt many high-strength and ultra-high-strength steel plates in the car body structure. The most prominent feature of the ultra-light steel car body through the large ULSAB is that it does not sacrifice performance to reduce the car's weight 4. The design basis of ultra-light steel vehicles is that the proportion of high-strength steel used in the body structure exceeds 90 percent . During the ten years from 1985 to 1995, high-strength steel in the body increased from 10 percent to 30 percent . With the surface treatment performance, The improvement of automobile life span extends from 6.7 years to 9.3 years. After deducting the energy increase in the manufacture of high-performance steel plates, 357104L of heavy oil can save a year, which is almost equivalent to saving a percentage of the energy consumption of the domestic steel industry. A few. In 2000, the use of high-strength steel plates in Japanese automobile manufacturing reached 36.3 percent .
