High-Precision Sheet Metal Enclosures for Power, Defence & Data Centre Needs in Hyderabad

Explore how Hyderabad’s sheet metal experts deliver custom enclosures—materials, testing, compliance—for power, defence, IT & data-centre sectors.

Introduction: Why Enclosure Precision Matters More Than Ever

From defence systems to data centres and energy infrastructure, industries rely heavily on custom-built metal enclosures to safeguard vital equipment. In sectors where environmental protection, electromagnetic shielding, and structural integrity are non-negotiable, the quality of your enclosure fabrication partner makes all the difference.

At Kalina, based in Hyderabad, we specialize in precision-engineered sheet metal enclosures for high-performance industries. This guide helps procurement professionals and technical buyers understand what goes into a high-quality enclosure—and how the right fabrication partner can help you meet specs, timelines, and compliance standards.

Industry-Specific Enclosure Requirements

Different sectors have unique demands when it comes to enclosures:

⚡ Power & Energy

• Must withstand high heat, dust, and outdoor exposure

• Often require IP-rated protection for switchgear and panels

• Common in substations, BMS panels, EV charging stations

🛡 Defence & Space

• Require tight tolerances, anti-corrosive coatings, and EMI shielding

• Materials must meet MIL-SPEC or other defense compliance

• Often involve integration with surveillance, comms, or control systems

💾 Data Centres & IT

• Must support airflow and cooling integration

• Require modular designs, quick access panels, and grounding

• Enclosures for 19” server racks, battery banks, network gear

Understanding these nuances is key to avoiding design errors and costly rework.

Materials & Grades: Mild Steel vs. Stainless Steel

Choosing the right material isn’t just about cost—it affects durability, corrosion resistance, and compliance. Here's a breakdown:

🔩 Mild Steel (MS)

Grade	Use Case	Properties
IS 2062 E250	General-purpose enclosures, cabinets	Good weldability, cost-effective
IS 1079 CRCA	Control panels, kiosks	Smooth finish, good formability
ASTM A36	Racks, base frames	Structural strength, easy fabrication

Mild Steel Advantages: Easy to weld, cut, and paint. Excellent for powder coating.

🛡 Stainless Steel (SS)

Grade	Use Case	Properties
SS 304	Outdoor enclosures, food-grade panels	Corrosion resistant, non-magnetic
SS 316	Marine, chemical, defence enclosures	High corrosion resistance (chlorides, salts)
SS 409	Automotive and HVAC	Heat resistant, moderately corrosion resistant

Stainless Steel Advantages: Long-term durability, low maintenance, perfect for harsh environments.

Our Fabrication Expertise: Built for Compliance

Kalina’s sheet metal fabrication unit in Hyderabad combines modern machinery, seasoned welders, and stringent QA processes to meet your specs.

We use:

• CNC laser cutting & turret punching for precision profiles

• TIG/MIG welding with jigs to maintain geometry

• 8 Tank powder coating with 2 booths for consistent finishes

• Press brakes for forming complex bends

We also provide CAD-to-part services for clients who share DXF, DWG, or STEP files.

Testing & Certification: Meeting Regulatory Requirements

We ensure our enclosures comply with standards like:

• IP Rating (Ingress Protection) – Tested for dust, water ingress

• EMI/EMC Shielding – Using conductive gaskets or SS mesh

• ISO 9001:2015 Compliance – Process and quality assurance

• MIL-SPEC / ASTM – For defence and export requirements

Optional tests include salt spray (corrosion), drop tests, thermal performance, and grounding continuity.

• 7-tank pre-treatment

• Powder-coated RAL7035 finish

• IP55 rating for indoor control environment

• Provision for cooling fan and glass door

Delivered: 30 enclosures in 7 daysResult: Reduced assembly time by 22%, improved airflow by 18%

Contractor Checklist: 8 Questions to Ask Before You Fabricate

1. Can the fabricator work with your desired material grade?

2. Do they offer CAD/CAM support and drawing verification?

3. Are their welds and tolerances documented?

4. What finishing and coating options are available?

5. Do they have prior experience with your sector?

6. Can they meet IP/MIL/ISO standards?

7. Are they equipped for batch or scalable production?

8. How quickly can they deliver prototypes and production parts?

Final Thoughts: Precision Fabrication is a Business Asset

When you're building infrastructure for critical sectors like power, defence, or IT, enclosure failure isn’t an option. Working with a fabrication partner like Kalina ensures that every weld, bend, and bolt is purpose-built to perform.
