Ductile iron street boxes provide durable, surface-level access and mechanical protection for buried utility equipment, including underground gate valves and hydrants. Engineered from robust EN-GJS-500-7 ductile iron, these units withstand roadway traffic loads and ground settlement in municipal infrastructure. Each street box features a protective epoxy coating of minimum 250 μm for long-term corrosion resistance in potable water and industrial distribution networks. They pair seamlessly with extension spindles for ground-level valve operation.
