Strong against rust and with short delivery times! High corrosion-resistant pull boxes that are resistant to salt damage and alkaline environments.
The "SD-Pull Box" is a pull box made of high corrosion-resistant galvanized steel sheet "Super Dyma(R)." It exhibits strong corrosion resistance even in salt damage areas and alkaline environments, with approximately 30 times the corrosion resistance of hot-dip galvanized steel sheets demonstrated in salt spray tests on flat surfaces. 【Features】 ■ High corrosion resistance... Approximately 30 times the corrosion resistance of hot-dip galvanized steel. ■ Short delivery time... No need for post-galvanizing or post-coating, allowing for shorter delivery times! ■ Improved workability... Good processability, lightweight, and reduces on-site work! 【For more details, please download the catalog or feel free to contact us】

basic information
Pull boxes are essential for electrical wiring work, including branching, junctions, and extensions. Among them, our high corrosion-resistant pull boxes have received positive feedback and have a proven track record of many deliveries. 【Features of the SD Box】 ■ High corrosion resistance compared to hot-dip galvanized coatings → While hot-dip galvanizing forms a protective film, it is rough compared to Super Dima, allowing moisture and oxygen to penetrate and accelerate corrosion. Super Dima has a dense protective film that suppresses and stabilizes the progression of corrosion. ■ The corrosion resistance, as seen from the rate of reduction of the coating layer in salt spray tests, is confirmed to be about 30 times higher than that of hot-dip galvanized steel plates, demonstrating extremely high corrosion resistance. ■ Protection of cut edges and welds → The cut edges of Super Dima may initially show red rust due to exposed base metal. However, the coating components around the cut edges dissolve to form a dense protective film, which covers the cut edges within a few months. This protective film has low electrical conductivity, effectively suppressing the progression of corrosion at the edges. * "Super Dima" is the product name for high corrosion-resistant galvanized steel sheets from Nippon Steel Corporation.
