Industrial Mild Steel Enclosures: Full-Weld Construction, IP66 Protection, and Custom Fabrication

Industrial environments demand durable and reliable electrical enclosures that protect critical components from water, dust, mechanical impact, and corrosion. At ホーフェン・ファブリケーション, we specialize in designing and manufacturing high-performance mild steel enclosures tailored for demanding outdoor and industrial applications.

Our mild steel enclosures deliver IP66 protection, IK10 mechanical impact resistance, and are engineered for use in temperatures ranging from -40°C to +80°C. This makes them suitable for power distribution, IoT systems, electrical control, communication modules, automation equipment, and a wide range of industrial applications.

Full-Welded Construction for Superior Strength

Unlike low-cost enclosures that are spot-welded from several machine-cut plates, our cabinets are fully welded as a single piece. Full welding ensures:

✓ Increased structural strength
✓ Better rigidity under mechanical stress
✓ Improved sealing performance
✓ Longer service life in harsh outdoor conditions
✓ Reduced deformation during installation and transport

With full welding, the steel cannot be too thin, which is why we use cold-rolled steel and maintain strict thickness control for both the cabinet body and the door.

Material & Specifications

Corrosion & Rust Protection Surface Finish

After welding, every enclosure undergoes:

Phosphating + Powder Coating

This treatment significantly enhances:

✓ Adhesion of paint
✓ Corrosion resistance
✓ Anti-rust performance
✓ Lifespan under outdoor exposure

This is a key advantage over low-cost cabinets that rely solely on cheap paint coatings.
