Product Description

CNC Stamped Stainless Steel Shelf Bracket for Industrial and Commercial Use

Shelf brackets may not be glamorous, but their failure can have serious consequences. We manufacture stainless steel shelf brackets specifically designed for industrial, commercial, and food processing applications. While mild steel with powder coating works for home use, SS 304 brackets offer superior longevity in wet and corrosive environments, making them the smart choice for demanding applications.

The bend radius is the most critical feature. For SS 304 (1.5mm thickness), we maintain a consistent 2.5-3.0mm inside bend radius—optimized to prevent cracking while ensuring maximum load capacity. Our engineering ensures each bracket meets rigorous performance standards.

Key Features

SS 304 Construction: Corrosion-resistant stainless steel ideal for food processing, commercial kitchens, laboratories, and outdoor installations. No coating to chip or rust to contaminate products.
Controlled Bend Radius: Inside bend radius maintained at 2.5-3.0mm for 1.5mm material to prevent cracking and ensure uniform strength.
Precision Hole Pattern: Mounting holes punched or CNC drilled to ±0.2mm position tolerance with standard or custom patterns available.
Stiffening Features: Optional return flanges and embossed ribs for increased load capacity without additional material thickness.
Surface Finish Options: Brushed finish (standard), mirror polish, bead blast, or 2B mill finish. All surfaces deburred for safe handling.

Frequently Asked Questions

What size bracket do I need for a 100kg load?

For a uniformly distributed 100kg load, you typically need a bracket with a 250-300mm vertical leg and 200-250mm horizontal support in 2.0mm SS 304, with a return flange for added stiffness. We'll calculate exact requirements based on your specific configuration.

SS 304 or SS 316 for outdoor brackets?

SS 304 for covered outdoor areas; SS 316 for exposed locations with salt spray or coastal environments. The 30% cost difference provides significant corrosion resistance improvement in chloride environments.

Can you make brackets with powder coating?

Yes, but we recommend mild steel instead for powder coating applications. Stainless steel's primary advantage is not needing coating, and mild steel offers 30-40% material cost savings.

What's the minimum bend radius for SS 304?

Theoretical minimum is 1.5x material thickness. We design for 1.7-2.0x (2.25-3.0mm for 1.5mm SS 304) to prevent cracking. Tighter bends may require increased material thickness.

Do you supply the mounting hardware?

Yes, we can supply matching SS 304 mounting hardware as a kit with brackets, ensuring fastener compatibility with bracket hole sizes.

What's the lead time for 1,000 brackets?

10-15 days for new designs (3-5 days tooling setup). Repeat orders with existing tooling: 7-10 days.
