Custom Stainless Steel Electrical Enclosures

Huarui provides professional stainless steel sheet metal fabrication services tailored for industries requiring the highest standards of durability and aesthetics. We specialize in working with high-grade alloys like 304 and 316L, utilizing precision laser cutting and multi-axis CNC bending to achieve tight-tolerance results. Our team is expert in advanced welding techniques and high-end surface finishing, including brushed and mirror polishing, ensuring that every enclosure and bracket meets your strict visual and functional requirements. From medical-grade components to heavy-duty industrial frames, we deliver DFM-optimized solutions that are built to last in even the most demanding environments.

Specifications

Why Choose Stainless Steel for Your Project?

• Corrosion Resistance: Self-healing chromium layer prevents rust in harsh, humid, or coastal environments.

• Hygienic Surface: Non-porous and easy to sanitize—mandatory for Medical and Food-grade applications.

• Aesthetic Appeal: Premium look with Brushed (No.4) or Mirror finishes; no painting required.

• Temperature Stability: Maintains high strength in both extreme heat and cryogenic cold.

• Sustainability: 100% recyclable with an exceptionally long service life, reducing long-term costs.

FAQ

Q: Can you match the brushed grain across multiple welded panels? 

A: Yes. Our skilled finishers specialize in grain matching. After welding, we grind and re-brush the joints to ensure the "Hairline" or "No.4" finish flows seamlessly across the entire assembly.

Q: Do you offer 316L for marine or medical applications? 

A: Absolutely. We frequently process 316L stainless steel for its superior resistance to chlorides and corrosion. We provide full material certifications (MTR) to verify the grade for compliance.

Q: Is your aluminum RoHS compliant? 

A: Absolutely. All our materials and surface treatments meet RoHS and REACH standards for export to the EU and North American markets.

Q: Can we sign a Non-Disclosure Agreement (NDA) before sharing our designs? 

A: Certainly. We protect the intellectual property of our global clients as a standard practice. You are welcome to send us your company’s NDA, or we can provide our standard agreement for your review.

Q: How do you handle "Design for Manufacturing" (DFM) feedback?

 A: Once we receive your RFQ, our engineers perform a complimentary DFM review. If we identify potential issues—such as a bend radius that might crack or a weld that’s inaccessible—we will provide a detailed report with suggested optimizations to improve quality and reduce costs.

Q: What are your payment terms for international orders? 

A: For new clients, our standard terms are typically a 30%-50% deposit to initiate the order, with the balance due after you approve the final production photos and inspection reports before shipping. For long-term partners with high-volume orders, we are open to discussing more flexible credit terms.
