High corrosion-resistant pull box "SD-Pull Box" [suitable for outdoor use]

Strong against rust and with short delivery times! 'High Corrosion-Resistant Pull Box' that is resistant to corrosion even in salt damage areas 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... About 30 times the corrosion resistance of hot-dip galvanized steel. ■ Short delivery time... No need for post-galvanizing or post-coating, allowing for a shorter delivery time! ■ 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 SD-Box】 ■ High corrosion resistance compared to hot-dip galvanized coatings → While hot-dip galvanizing forms a protective film, it is coarser compared to Super Dyma, allowing moisture and oxygen to penetrate and accelerate corrosion. Super Dyma 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 Dyma may initially exhibit 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 and effectively suppresses the progression of corrosion at the edge. * "Super Dyma" is the product name for high corrosion-resistant coated steel sheets from Nippon Steel Corporation.
