Stainless Steel Terminal Boxes
IP Enclosures’ stainless steel terminal boxes are built for peak performance in the harshest industrial and hazardous environments. Designed to house electrical, electronic, or pneumatic components, these terminal boxes offer exceptional protection and reliability.
They boast IP66, IP67, and IP69K ingress protection ratings, with IECEx certification for use in hazardous areas classified as Zones 1, 2, 21, and 22. Constructed from 1.0 mm Grade 304 or 316L stainless steel, with robust screwed lids or doors, these boxes feature high-quality silicone seals and NBR‑70 washers. The silicone seals provide excellent chemical and petrochemical resistance, maintaining their flexibility and sealing integrity even when exposed to harsh chemicals, oils, fuels, and solvents commonly found in industrial and petrochemical environments. This resistance ensures reliable protection against ingress of liquids and contaminants, critical for maintaining operational safety in severe conditions. The brushed surface finish measures 0.2 µm Ra, enhancing cleanability and reducing corrosion risk.
Precision-manufactured in Italy, these terminal boxes include a pre-fitted internal mounting plate and are supported by a 5‑year warranty. Designed for zones requiring hazardous atmosphere certification, severe ingress protection, and chemical resistance, they are ideal for industries such as mining, oil & gas, chemical processing, and coastal infrastructure.
