· Product Overview
This precision-engineered mounting plate is custom-fabricated from high-grade 304/316 stainless steel via advanced sheet metal processes, finished with a mirror-polished surface. Featuring a rectangular profile with stepped edge rails, corner mounting holes, and central precision-drilled holes, it provides a rigid, corrosion-resistant platform for securing electronic components, mechanical assemblies, or industrial equipment. The mirror-polished finish delivers exceptional aesthetic appeal and easy cleaning, while the stepped edge design ensures precise alignment and stable installation. Ideal for applications requiring both structural durability and a high-end reflective appearance, this plate is a standout choice for industrial, electronic, and architectural use cases.
· Application Scenarios
This stainless steel mounting plate serves critical roles across multiple industries:
- Electronic Enclosures: Base plates for server chassis, industrial control boxes, and electronic component mounting (providing stable, corrosion-resistant support)
- Industrial Machinery: Mounting plates for sensors, actuators, and precision measuring instruments
- Medical Devices: Non-magnetic, easy-to-clean mounting plates for diagnostic equipment and portable medical instruments (316L variant)
- Architectural & Sanitary Hardware: Decorative mounting plates for luxury bathroom fixtures, handrails, and high-end sanitary ware
- Food & Beverage Processing: Hygienic mounting plates for food processing equipment and clean-in-place (CIP) systems (316L variant)
- Aerospace & Automotive: Lightweight, high-strength mounting plates for aerospace components and vehicle control systems
· Production Process Introduction
- Design & DFM Validation: Our engineering team optimizes plate dimensions, hole positions, and stepped edge geometry via Design for Manufacturability (DFM) analysis to ensure structural integrity and fabrication feasibility.
- Material Preparation: Premium stainless steel sheet stock is cut to size and deburred to create a clean base for fabrication.
- Precision Sheet Metal Fabrication:
- Cutting: The plate profile, stepped edges, and mounting holes are precision-cut via fiber laser for clean edges.
- Bending: CNC bending forms the stepped edge rails to ensure precise alignment and structural rigidity.
- Drilling: Central holes are drilled to tight tolerances for accurate component mounting.
- Mirror Polishing & Finishing: Parts undergo multi-stage mechanical polishing to achieve the mirror-bright finish, removing all burrs and surface imperfections, followed by passivation to enhance corrosion resistance.
- Quality Inspection: 100% dimensional inspection via CMM verifies compliance with hole positions and edge alignment, while a surface roughness test confirms the mirror finish quality.
- Final Packaging: Plates are individually wrapped in anti-scratch PE film and secured in custom foam trays to protect the mirror finish during transit.
· Packaging and Shipping Methods
- Standard Packaging: Each plate is wrapped in soft anti-scratch PE film, placed in custom-cut EPE foam inserts inside a reinforced corrugated box, with additional cushioning to prevent bending or surface scratching. For bulk orders, wooden pallets are used to secure multiple plates.
- Shipping Options:
- Express Delivery (3–7 Business Days): DHL/FedEx/UPS for prototype and small-batch orders (full tracking provided).
- Standard Sea Freight (25–40 Business Days): Cost-effective FCL/LCL options for large-volume production orders, with full customs documentation support.
- Custom Packaging: Branded labeling, barcoding, and custom tray inserts are available to align with your independent store’s brand guidelines and inventory management needs.

· Frequently Asked Questions (FAQ)
What is your Minimum Order Quantity (MOQ)?
Our MOQ is flexible to suit your independent store’s e-commerce needs:
- Prototypes/Samples:1 piece available for custom design validation.
- Production Runs: Starting at 50+ pieces for standard configurations. We specialize in low-volume, high-precision custom fabrication to match your online store’s demand.
What are your typical lead times?
- Prototype/Sample Orders: 7–12 business days from final CAD design approval (includes fabrication and mirror polishing).
- Mass Production: 15–25 business days, depending on order volume, plate complexity, and surface finish requirements.
- Rush Service: Expedited production (4–7 days for samples) is available upon request for urgent restocks.
Can you accommodate full custom modifications?
Absolutely. We offer end-to-end customization to align with your independent store’s product offerings:
- Size & Shape Customization: Custom plate dimensions, stepped edge profiles, and mounting hole configurations to fit your specific components.
- Material Upgrades: 316L stainless steel for high-corrosion environments, or 304 stainless steel for general industrial use.
- Surface Finish Options: Alternative finishes (brushed, bead blasted, or electropolished) for specific performance or aesthetic needs.
- Branding & Traceability: Laser engraving of logos, part numbers, or batch codes for full product traceability and inventory management.
