Hoffman cabinets are sturdy, durable metal enclosures used to house electronics and electrical components. They provide secure, protective housing for sensitive equipment in industrial, commercial, and utility applications. Knowing the gauge (thickness) of the metal is important for assessing the cabinet’s durability and ability to withstand impacts or harsh environmental conditions.
An Overview of Hoffman Cabinets
Hoffman cabinets have been a trusted industry standard for decades. They are available in a wide range of standard sizes and configurations to meet diverse application requirements. Typical features of Hoffman cabinets include:
- Constructed of sheet metal (steel or aluminum)
- Heavy-duty welded construction
- Louvered vents for ventilation and cooling
- Multiple knockouts for cable entry and interface
- FLange-mounted doors with gaskets for a tight seal
- Adjustable and removable internal mounting panels
- Grounding provisions
Hoffman offers hundreds of standard model cabinets in various depths, widths, and heights. Custom designs are also available when required.
Common Metal Gauges Used
The most common metal gauges used for Hoffman cabinet construction are:
16 Gauge
- Approximately 0.060 inches thick
- Provides good durability for indoor use
- Typically used for small enclosure designs
14 Gauge
- Approximately 0.075 inches thick
- Suitable for most indoor applications
- Provides extra impact resistance
12 Gauge
- Approximately 0.105 inches thick
- Excellent durability and dent resistance
- Used for larger enclosures and outdoor applications
10 Gauge
- Approximately 0.135 inches thick
- Maximum strength and protection
- Only used for specialty high-abuse applications
Thicker metal gauges provide greater structural rigidity and durability but add cost and weight. Proper gauge selection depends on the proposed operating environment and specific demands of the application.
Gauge Information for Hoffman Models
To determine the metal gauge used for a particular Hoffman enclosure, consult the specification sheet or technical drawings for that model number. Gauge will vary based on size and intended use. Here are some examples for common models:
Hoffman PROLINE Cabinets
- PROLINE Small: 16 gauge
- PROLINE Medium: 14 gauge
- PROLINE Large: 12 gauge
- PROLINE Extra Large: 10 gauge
Hoffman Standard A Series
- Hoffmann A12: 16 gauge
- Hoffman A16: 14 gauge
- Hoffman A24 and larger: 12 gauge
Hoffman Outdoor Cabinets
- Fiberglass NEMA 4X: Gelcoat finish over fiberglass
- Stainless Steel NEMA 4X: 14 gauge Type 304 stainless
Hoffman Wall-Mount Network Cabinets
- Hoffman Network Wall Boxes: 16 gauge
- Hoffman Network Floor Cabinets: 14 gauge
Considerations When Selecting Gauge
Key factors to consider when selecting the appropriate metal gauge for a Hoffman cabinet include:
- Environment – Indoor, outdoor, hazardous locations? Gauge needs to suit.
- Abuse – Will the enclosure be exposed to impacts, vibration, or abrasion?
- Weight – Will higher gauge metal exceed weight limits for wall mounting?
- Thermal – Thicker metal provides more insulation for heat/cold sensitive contents.
- Cost – Increased metal gauge adds to manufacturing costs substantially.
- Standards – Any specifications or standards that dictate construction?
Matching the metal gauge thickness to the end application ensures optimal performance and life expectancy from Hoffman cabinets. Consult Hoffman’s technical team for recommendations when unsure about proper gauge selection.
Common Questions About Metal Gauge in Hoffman Cabinets
What is the metal thickness for a Hoffman A-48 cabinet?
The standard A-48 cabinet from Hoffman is constructed of 14 gauge steel, approximately 0.075″ thick. Optional 12 or 10 gauge construction is available if required.
Can I get Hoffman Small enclosures in heavier than 16 gauge metal?
Hoffman’s small cabinets like the A-12 are usually only manufactured in 16 gauge steel. However, custom fabrication in heavier gauge metals can be requested for unique applications requiring it.
Why are thicker metal gauges generally better?
Heavier gauge metals are stronger, more rigid, and more resistant to denting or penetration. This makes them suitable for protecting contents in highly demanding environments. The tradeoff is increased cost and weight.
How is gauge specified when ordering Hoffman cabinets?
The catalog standard gauge for each model is assumed unless otherwise specified. Custom orders can request alternate gauge metals as needed, though pricing may be higher.
Is 12 gauge steel the same thickness as 12 gauge stainless?
Not necessarily – gauge numbers refer to relative thickness but the type of steel or stainless will impact exact thickness. It’s best to consult metal thickness charts to compare.
Conclusion
Hoffman is a major supplier of protective metal cabinets and enclosures across many industries. Understanding the typical metal gauges used in their standard product line allows proper selection for the intended operating conditions. From thin 16 gauge models for indoor use to heavy-duty 10 gauge designs for maximum durability, Hoffman offers quality all-welded cabinets across a range of metal thicknesses. Checking the technical specifications and consulting with Hoffman’s engineering team is advised to match the metal gauge thickness to the specific environmental and performance requirements.
