Hongming Sheng manufactures custom stainless steel electrical enclosures using SUS304 and SUS316 according to customer drawings and application requirements.

We support waterproof and dust-resistant enclosure structures for outdoor electrical equipment, control systems, industrial electronics and other demanding environments.

SUS304 & SUS316 Enclosure Fabrication

Stainless steel is widely used for electrical enclosures where corrosion resistance, strength and long-term durability are important.

Waterproof Enclosure Design Features

Waterproof performance depends on the complete enclosure design, including door structure, sealing, openings and assembly details.

• Gasket sealing around doors and removable panels
• Overlapping or folded edge structures
• Custom cable entry and gland openings
• Door hinges, locks and compression hardware
• Internal mounting plates and brackets
• Outdoor-oriented drainage or cover features when required

IP65 Requirement Support

If your project requires an IP65 enclosure, please provide the sealing specification, opening details and test requirements with your drawing.

We can manufacture the enclosure structure according to the agreed design requirements and support fit checks for doors, gaskets, covers and mounting interfaces.
