Junction Box Price in India: PVC, ABS, SMC and Metal

Junction box prices in India range from about ₹10-₹50 for a small PVC box to several thousand rupees for large metal, stainless steel or flameproof boxes. In listings we checked on Indian B2B marketplaces in November 2026, small PVC and ABS boxes mostly cost about ₹40-₹500, IP65 polycarbonate boxes about ₹100-₹800, SMC/FRP boxes about ₹250-₹950, aluminium boxes about ₹230-₹4,000, and stainless steel boxes about ₹850-₹6,500 per piece. The price depends mainly on material, size, IP rating, brand, accessories and quantity.

“Junction box price” is one of the most searched electrical terms in India, but a single number does not help: a ₹40 PVC box and a ₹4,000 aluminium box are both called junction boxes. This guide compares junction box prices by material, explains what makes one box cost more than another, and shows how to get the right box at the right price.

We are a tool room that builds the compression moulds used to make SMC junction boxes. We do not sell boxes, so the price ranges below come from seller listings, not from us.

Junction box price by material

Source: seller-listed prices on IndiaMART and TradeIndia, November 2026. Prices change, vary by size and brand, and usually exclude GST and freight. Use them as a guide, not a quotation.

PVC junction box price

PVC junction boxes are the cheapest, from about ₹10 for a small open box to a few hundred rupees for an IP65 weatherproof box. They suit indoor wiring and CCTV camera points. PVC softens with heat and becomes brittle in strong sunlight over time, so for exposed outdoor sites choose polycarbonate or SMC.

ABS and polycarbonate junction box price

ABS boxes typically cost about ₹50-₹500 in common sizes such as 100×100 mm to 200×200 mm. Polycarbonate boxes cost more than ABS of the same size but are much tougher, handle higher temperatures and are available UV-stabilised for outdoor use. Large branded IP65 polycarbonate enclosures can cost several thousand rupees.

SMC / FRP junction box price

SMC (fibreglass polyester) junction boxes typically cost about ₹250-₹950 depending on size and fittings. They are moulded in heated steel moulds, do not rust or conduct electricity, hold their shape in heat, resist UV and are available in fire-retardant grades. For outdoor utility and industrial use they often cost the least over their life. Read our guide to SMC junction boxes and meter boxes.

Metal junction box price

• Aluminium: die-cast aluminium boxes cost about ₹230 for small weatherproof boxes up to ₹4,000 or more for larger and flameproof boxes. They are rugged and shield against electrical interference, but must be earthed.
• Mild steel / GI: small conduit boxes cost very little, but powder-coated steel junction boxes and panel boxes rise into thousands of rupees as size grows. Steel rusts once the coating is damaged.
• Stainless steel: about ₹850-₹6,500 per piece in listed sizes. Used where hygiene or corrosion resistance is essential.

What decides junction box price

1. Material and grade: PVC is cheapest, then ABS, polycarbonate, SMC, aluminium and stainless steel. UV-stable and fire-retardant grades cost more.
2. Size and wall thickness: bigger boxes and thicker walls use more material.
3. IP rating: IP65, IP66 and IP67 boxes need better gaskets, lid design and screws than basic IP54 boxes.
4. Accessories: mounting plate, DIN rail, terminal blocks, cable glands, hinges, locks and windows add to the price.
5. Certification: flameproof (hazardous-area) boxes and tested, certified boxes cost much more.
6. Brand: branded enclosures cost more than generic boxes of similar size, partly for consistency and testing.
7. Quantity: moulded boxes get much cheaper per piece in bulk, because the mould cost is shared across every box.

How to compare junction box quotes

When you ask for prices, give every supplier the same specification:

• Material and grade (for example, UV-stabilised polycarbonate or fire-retardant SMC).
• Internal size and depth.
• IP rating and, if needed, IK impact rating.
• Number and size of cable entries, glands or knockouts.
• Accessories: mounting plate, DIN rail, terminals, hinges, lock.
• Colour and any marking.
• Quantity, delivery location, and whether GST and freight are included.

Then compare the total cost of the box you actually need, not just the shell.

How to save on junction boxes without buying the wrong one

• Do not over-specify indoors. A basic ABS or PVC box is fine for dry indoor wiring.
• Do not under-specify outdoors. A cheap box that cracks or leaks in two summers costs more than one good SMC or polycarbonate box.
• Use standard sizes instead of custom sizes.
• Buy in bulk for projects, and ask for project pricing.
• Choose fittings carefully: glands and terminal blocks are often a large part of the total.

For junction box manufacturers: the mould decides cost

If you manufacture junction boxes, the price you can offer depends heavily on your mould. A good compression mould gives short cycles, thin flash, little rework and long life, which lowers your cost per box. A poor one gives thick flash, rejects and constant repairs.
