Custom Stainless Steel Enclosure​

Q: What is the standard lead time from CAD approval to shipping?

Standard lead times typically range from 2 to 4 weeks, depending on the complexity of the enclosure (e.g., custom thermal management integrations or special powder-coated finishes). However, because we provide quotes within 24 hours, you will know your exact, guaranteed shipping date before you issue the Purchase Order.

304 vs. 316L for Your Custom Stainless Steel Enclosure

A poorly specified custom stainless steel enclosure will fail in the field within 6 months. Instead of just bending metal, ShincoFab audits your material choice against your exact operating environment to guarantee NEMA 4X/6P integrity.

Type 304 Stainless Steel for General Industrial Applications

Best For: General manufacturing floors, indoor warehouses, and standard outdoor environments without severe chemical exposure.
Properties: Excellent resistance to standard oxidation and mild acids.
The Danger Zone: Do not use 304 in environments with high chlorides (salt) or caustic chemicals. It is highly susceptible to pitting and crevice corrosion under these conditions.

Type 316L Stainless Steel for Harsh Environmental Applications

The Difference: Contains 2-3% Molybdenum, drastically increasing resistance to chloride-induced pitting. The “L” (Low Carbon) prevents carbide precipitation during welding, ensuring maximum corrosion resistance at the seams.
Mandatory For: Marine and offshore applications, food & beverage processing (IP69K high-pressure/caustic washdowns), wastewater treatment, and pharmaceutical cleanrooms.

Engineered to Your Structural Requirements

Depending on the physical size of your enclosure and load-bearing needs, we stock and precision-fabricate the following standard gauges:

16-Gauge (1.5mm): Ideal for small junction boxes and lightweight wall-mounts.
14-Gauge (2.0mm): The standard for mid-sized NEMA 4X enclosures.
12-Gauge (2.5mm): For large freestanding or heavy-duty industrial cabinets.
10-Gauge (3.0mm): Maximum rigidity for explosion-proof (ATEX) or severe-impact environments.

Protect Your $50,000 VFD with Engineered NEMA and IP Compliance

Slapping a generic waterproof label on a bent box doesn’t pass a sanitary audit, nor does it protect your controls from a 1,450 PSI washdown. ShincoFab goes beyond basic ratings to engineer the exact mechanical modifications required to ensure your internal components survive your worst nightmare scenarios.

NEMA 4X / IP66 for Corrosive Washdown Defense

The Threat: Petrochemical plants, wastewater facilities, and heavy hose-downs.
Our Solution: We guarantee absolute protection against windblown dust, heavy directed water jets, and severe corrosion. Every seam is TIG welded, and every door is fitted with a poured-in-place (FIP) polyurethane gasket to ensure a watertight seal that won’t degrade over time.

IP69K for Food & Beverage Sanitary Applications

When you need a true washdown enclosure or hygienic enclosure, surviving 80°C (176°F) water blasted at 1,450 PSI requires more than just good steel. To ensure you pass strict FDA and USDA audits, we modify your CAD with specific sanitary design rules:

Sloped Roofs (Top-Pitch): We engineer 2° to 10° sloped tops so contaminated water and cleaning chemicals run off immediately, preventing pooling.
Continuous Seam Welds: Spot welding is unacceptable here. We use continuous welds, ground flush and polished (up to Ra 0.8 µm) to eliminate microscopic crevices where bacteria hide.
FDA-Approved Silicone Gasketing: High-temperature, non-absorbent seals that withstand brutal daily caustic chemical cleaning without cracking.

ATEX / IECEx Compatibility for Hazardous Locations

The Threat: Explosive gas or combustible dust environments (oil refineries, grain silos, chemical processing).
Our Solution: Where a single spark means catastrophe, structural integrity is everything. We fabricate using heavy-gauge steel (up to 10 GA) to provide the extreme rigidity and spark-proof sealing precision required to safely house your purged/pressurized systems or flameproof components.

Eliminate Field Modifications with Exact-Fit Customization Ready for Assembly

If your technicians have to drill a hole or modify a cutout on the factory floor, we’ve failed you. Field modifications destroy the integrity of stainless steel and void your NEMA ratings. Send us your CAD, and we will deliver a 100% turnkey enclosure. It arrives fully punched, welded, integrated, and ready for your controls on day one.

Dimensional Flexibility

From compact stainless steel junction boxes and custom wall mount stainless steel enclosures to massive, 2-meter tall custom floor mount stainless steel enclosures. If you can draw it, we can bend it.

Precision Machining & Cutouts

Delivering a custom stainless steel enclosure with cutouts means zero field drilling. We provide pre-punched holes and threaded extrusions for rapid mounting.
Laser-cut HMI (Human-Machine Interface) windows and precise push-button arrays.
Custom gland plates (singular or split) for simplified cable entry without compromising the seal.

Thermal Management Integration

Custom-engineered sun shields to mitigate high solar loads in desert or outdoor offshore environments.
Pre-cut louvers, filter fan arrays, and precision cutouts ready for vortex coolers or heavy-duty HVAC units.

Hardware & Mounting Solutions

Welded-in-place interior sub-panels and DIN rail mounting studs to eliminate external bolt holes.
Heavy-duty 3-point latches, lockable T-handles, and padlocking L-handles.
Sanitary lift-off hinges with no exposed threads (critical for food & beverage compliance).

Stop Bacteria Hiding in Scratches with Precision Engineered Surfaces

In critical environments, the surface finish is not an aesthetic choice; it is a functional requirement. A microscopic pit is a breeding ground for pathogens or the starting point for crevice corrosion. We deliver precision-controlled finishes designed to pass sanitary audits and endure aggressive washdowns.

No. 4 Brushed Finish (180-220 Grit) as The Sanitary Standard

Best For: Food & Beverage, Dairy, and Pharmaceutical applications.
The Function: This unidirectional, brushed finish achieves a low surface roughness (Ra) that eliminates microscopic pits where bacteria or contaminants hide. It is the mandatory standard for components subjected to regular high-pressure (IP69K) caustic washdowns.

2B Mill Finish as The Industrial Workhorse

Best For: General manufacturing, concealed internal panels, and standard NEMA 4X outdoor environments.
The Function: A smooth, unbrushed, moderately reflective finish right off the mill. It offers excellent baseline corrosion resistance without the added cost of secondary polishing.

Powder Coated Stainless Steel as The Dual-Layer Defense

Best For: Extreme chemical environments or mandatory corporate color-coding (e.g., Safety Yellow or Fire Red).
The Function: We apply a highly durable, baked-on polyester or epoxy powder coat over the 304/316L base. This provides a sacrificial barrier against aggressive localized wear while maintaining the indestructible stainless core.

Frequently Asked Questions

We hate vague marketing answers as much as you do. Before you send us your CAD files, here are the hard facts regarding our MOQs, hidden costs, and lead times. No fluff, just the details you need to make an informed supplier decision.

What is your Minimum Order Quantity (MOQ)? Do you accept 1-off prototypes?

We do not have a strict MOQ. Yes, we routinely fabricate 1-off custom prototypes. We know that proving the design in the field with a first-article prototype is the only way to secure the 100-unit production run. You will receive the exact same engineering rigor for a single box as you would for a full truckload.

Will I be charged expensive tooling or setup fees for custom cutouts?

In 99% of cases, No. Because we utilize advanced 5-axis fiber laser cutting technology, custom HMI window cutouts, non-standard louver patterns, or unique gland plate layouts are simply programming changes. We don’t need to build a $5,000 physical punch die just to cut a custom hole. This keeps your upfront costs extremely low.

How can I verify that I am actually receiving 316L and not cheaper 304 stainless?

We never ask you to take our word for it. Every custom enclosure we ship includes fully traceable Material Test Reports (MTRs) directly from the steel mill. These documents prove the exact chemical composition (including Molybdenum content) of the steel used in your specific batch, ensuring your compliance audits go smoothly.

What is the standard lead time from CAD approval to shipping?

Standard lead times typically range from 2 to 4 weeks, depending on the complexity of the enclosure (e.g., custom thermal management integrations or special powder-coated finishes). However, because we provide quotes within 24 hours, you will know your exact, guaranteed shipping date before you issue the Purchase Order.

Are your enclosures UL Listed or certified?

We manufacture strictly to NEMA 4X, NEMA 6P, IP69K, and UL 508A structural guidelines. If your project specifically requires a physical UL Label applied to the enclosure prior to shipping, please specify this in your RFQ. We have the capability to provide certified labeling to meet your electrical inspector’s requirements.
