How to Choose the Right Sandwich Panel Manufacturer

Whether you’re building a cold storage, warehouse, prefab office, or industrial shed, one of the most crucial decisions you’ll make is choosing the right sandwich panel manufacturer. The quality, reliability, and performance of your building depend significantly on the panels used — and not all manufacturers are the same.

At EPACK Prefab, we’ve worked with hundreds of industrial and commercial clients across India and South Asia, and we understand the challenges buyers face. This guide will help you evaluate key factors to ensure you’re partnering with a manufacturer who delivers value, quality, and peace of mind.

✅ 1. Evaluate Manufacturing Capabilities

Start by understanding how and where the manufacturer produces their panels.

Do they have a fully automated continuous line or use manual, discontinuous methods?
Are they equipped for large-volume orders with consistent quality?
Can they manufacture different core materials like PUF, PIR, EPS, and Rockwool?

EPACK Prefab uses state-of-the-art continuous line production at our Mambattu facility in South India, ensuring high-speed, consistent panel manufacturing with zero compromise on quality.

🧪 2. Check Quality Assurance Standards

A trustworthy manufacturer should follow rigorous quality control measures during and after production.

Ask these questions:

Are raw materials like steel and foam tested before use?
Are panels checked for thermal conductivity, strength, and fire resistance?
Are their products certified by third-party testing agencies?

At EPACK, each panel undergoes thermal, water absorption, dimensional accuracy, and mechanical strength tests to ensure only the best reaches your project site.

📍 3. Look for Local Presence and Delivery Capability

Timely delivery is crucial. A manufacturer with a plant near your project site will help in:

Reduced logistics cost
Faster delivery & support
Easier coordination during installation

With our Mambattu plant (near Chennai), EPACK is strategically located to serve Tamil Nadu, Andhra Pradesh, Telangana, Karnataka, and Kerala efficiently.

🛠️ 4. Check for Customization Options

Each project has unique needs — from panel thickness to fire rating and finishes.

Choose a manufacturer that can:

Offer multiple panel profiles (roof, wall, hidden screw)
Supply in custom lengths and thicknesses
Provide different insulation cores (PUF, PIR, EPS, Rockwool)
Offer R&D and technical guidance

EPACK Prefab provides complete panel customization based on application, aesthetics, and environmental requirements.

🏗️ 5. Experience in Relevant Sectors

Has the manufacturer worked on projects similar to yours?

Look for experience in:

Cold chain logistics
Food processing units
Warehouses & industrial sheds
Prefab schools, hospitals, offices
Clean rooms or data centers

EPACK has executed 1000+ projects across India in diverse sectors — and we bring that experience into every panel we deliver.

💬 6. Ask for Client Testimonials and Case Studies

Reputable manufacturers will gladly share their success stories.

Check for testimonials from clients in similar industries
Look at case studies or project galleries
Ask for references, if needed

EPACK’s clients include leaders in infrastructure, FMCG, pharma, warehousing, and government institutions.

🔍 7. Transparency in Pricing and Support

A good manufacturer will:

Provide clear pricing with no hidden costs
Offer on-site technical support or consultation
Help with installation guidance and accessories

At EPACK Prefab, we offer transparent project pricing, pre-sales consultations, and after-sales support, ensuring a hassle-free experience.
