伸光金属工業 Product Lineup

Overwhelming corrosion resistance in marine environments Aluminized grating exhibits exceptional corrosion resistance in marine environments. The oxide film formed on the surface protects the grating, achieving corrosion performance that is approximately 20 times greater than that of hot-dip galvanized coatings. As a result, it is resistant to corrosion even in port facilities, coastal buildings, and salt-damaged areas, allowing for safe use over long periods. With a long lifespan, it significantly reduces lifecycle costs, and its corrosion resistance greatly decreases the frequency of replacements and maintenance. • Human costs • Labor time • Material costs • Consumption of Earth's resources All of these can be collectively reduced. Aluminizing is a 100% aluminum hot-dip coating. Since it does not contain harmful substances, it complies with the RoHS directive and can be safely adopted as an environmentally friendly grating. Comprehensive benefits • Resistant to corrosion for long periods even in salt-damaged environments • Reduced maintenance frequency, lowering total costs • Environmentally friendly material that is sustainable • Long lifespan that helps conserve resources

• Steel

Melted aluminum coating has 20 times the corrosion resistance of galvanized coating in seawater corrosion (splash zone). If you are troubled by corrosion due to seawater and salt damage, please feel free to consult us. We will help extend the life of your assets, achieve SDGs, alleviate labor shortages through maintenance-free solutions, and reduce costs.

Are you having trouble with stainless steel bolts and nuts that won't come off? You can reduce the time and costs associated with replacement, maintenance, and inspection work. By applying our molten aluminum coating (Aluminize α treatment) to stainless steel materials, we can dramatically improve galling and seizure resistance to 1/80 of the original material. Additionally, removed stainless steel bolts and nuts can be reused. Heat resistance is also improved simultaneously. In an environment of 850°C, the durability of SUS304 with Aluminize α treatment is increased by 100 times.

★For a limited time, request materials and receive a free sample (Aluminized α-treated hex bolt)! For corrosion resistance, heat resistance, wear resistance, and prevention of bolt seizure and galling! Perfect for those troubled by bolt corrosion or galling! ＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝ Aluminized bolts are a new type of metal created by plating aluminum onto bolts, forming an alloy compound of aluminum and iron, and featuring a two-layer structure with aluminum adhered to the surface. ＝＝＝　Features　＝＝＝ ● Exhibits sacrificial corrosion protection effects in electrolytic solutions. ● Forms a robust oxide film in the atmosphere, providing exceptional rust prevention. ● The rust prevention effect in coastal and seawater environments is about 10 times that of galvanized coatings. ● Uses pure aluminum in the plating process, making it an environmentally friendly rust prevention treatment.
