Understanding aluminum material costs helps you make informed decisions when buying windows or doors in Nepal. While most homeowners buy finished products, knowing raw material prices helps you evaluate whether quotes you receive are reasonable.
This guide explains current aluminum prices in Nepal, what affects these rates, different aluminum grades, and how raw material costs translate to finished window and door prices.
Aluminum Quality Grades Explained
6063 Aluminum Alloy (Most Common)
Characteristics:

- • Easy to extrude (make profiles)
- • Takes powder coating very well
- • Good surface finish
Best For:
- • Window frames
- • Door frames
- • Partitions
- • Decorative trim
- • 90% of residential use
Price: Rs. 350-400 per kg | Availability: Readily available in Nepal | Our recommendation: Perfect for homes
6061 Aluminum Alloy (Premium)
Characteristics:
- • High strength
- • Excellent corrosion resistance
- • More expensive
- • Harder to work with
- • Better load-bearing capacity
Best For:
- • Structural components
- • Large curtain walls
- • Commercial buildings
- • Heavy-duty applications
- • When extra strength needed
Price: Rs. 450-550 per kg | Availability: Less common, order required | When to use: Only if engineer specifies
💡 For Homeowners in Nepal
Standard 6063 aluminum is perfectly adequate for all residential windows and doors. Don't pay extra for 6061 unless your engineer specifically requires it for structural reasons (very rare in normal homes). The Rs. 100-150/kg extra cost adds up significantly for a full home.
What Affects Aluminum Prices in Nepal?
1. International Aluminum Market Rates
Nepal imports all aluminum - we don't produce it locally. International aluminum prices (London Metal Exchange rates) directly impact Nepal prices with 1-2 month lag.
Impact: When global aluminum rises by $100/ton, Nepal prices rise by Rs. 15-20/kg within 2 months.
2. Import Duties & Taxes
Import duty, VAT, and customs clearance add 25-35% to base aluminum cost.
- • Import duty: 10-15%
- • VAT: 13%
- • Customs clearance: 2-3%
- • Total: ~25-35% markup on CIF price
3. Currency Exchange Rate (NPR vs USD)
Since aluminum is imported and priced in USD, when Nepali Rupee weakens against USD, aluminum gets more expensive in Nepal.
Example: If NPR/USD rate goes from 130 to 135, aluminum price increases by ~4% even if international rates don't change.
4. Purchase Quantity
Bulk buyers get better rates than small retail purchases.
- • 1-50 kg (retail): Rs. 400-420/kg
- • 50-200 kg: Rs. 380-400/kg
- • 200-500 kg: Rs. 365-385/kg
- • 500+ kg (wholesale): Rs. 350-370/kg
How Raw Aluminum Cost Becomes Window/Door Price
Let's break down how Rs. 400/kg aluminum becomes a Rs. 12,000 window:
| Cost Component | Details | Cost (Rs.) |
|---|---|---|
| Raw Aluminum | 10 kg @ Rs. 400/kg | 4,000 |
| Powder Coating | Full window coating + pre-treatment | 1,800 |
| Glass | 5mm clear glass, 15 sq ft | 2,200 |
| Hardware | Handles, locks, hinges, screws | 1,500 |
| Fabrication Labor | Cutting, welding, assembly | 1,200 |
| Overhead & Profit | Shop rent, equipment, margin (15-20%) | 1,800 |
| Installation | Labor, sealant, transportation | 800 |
| TOTAL | 13,300 |
Key Insight
Raw aluminum is only 30-35% of the final window cost. Even if aluminum price increases by Rs. 50/kg (12.5% rise), final window price only increases by Rs. 500 (3.7%). This is why window prices are relatively stable despite aluminum price fluctuations.
Aluminum Scrap Prices in Nepal
Scrap Value by Type
What This Means
- •Old aluminum windows have resale value - don't throw away!
- •A typical window (10 kg) = Rs. 2,200-2,500 scrap value
- •When replacing windows, sell old ones to offset new costs
- •Many fabricators will take old windows in exchange for discount
Where to Sell Aluminum Scrap in Kathmandu
- • Balaju Industrial Area: Multiple scrap dealers, best rates for bulk
- • Teku area: Several scrap collection centers
- • Kalimati: Scrap dealers near vegetable market
- • Local scrap collectors: Will come to your home but pay 10-15% less
Tips for Homeowners
✓ DO:
- • Ask fabricators what grade of aluminum they use (should be 6063)
- • Ask about profile thickness (should be 1.2mm minimum)
- • Get quotes from 3-4 vendors to compare final prices
- • Focus on final window/door price, not per kg rates
- • Check powder coating quality - this matters more than aluminum grade
- • Ask about warranties on finished products
✗ DON'T:
- • Don't try to buy raw aluminum and DIY (not cost-effective for small projects)
- • Don't choose vendor solely based on lowest per kg aluminum rate
- • Don't pay premium for 6061 unless engineer specifies it
- • Don't assume expensive aluminum automatically means quality windows
- • Don't buy from vendors who can't explain what grade they use

What is the difference between 6063 and 6061 aluminum?▼
6063 aluminum (Rs. 350-400/kg) is commonly used for windows/doors - good strength, easier to extrude, takes powder coating well. 6061 aluminum (Rs. 450-550/kg) is stronger, more expensive, used for structural applications. For Nepal homes, 6063 grade is perfectly adequate for windows and doors.
Why do aluminum prices vary so much in Nepal?▼
Aluminum prices vary due to: international aluminum market rates, import duties and taxes, quality/grade differences (6063 vs 6061), supplier margins, bulk vs retail purchase, and currency exchange rates. Prices can fluctuate 10-15% within a month based on these factors.
How does per kg price relate to window/door costs?▼
A typical window uses 8-12 kg of aluminum profiles. If raw aluminum is Rs. 400/kg, material alone costs Rs. 3,200-4,800. Add powder coating (Rs. 1,500-2,000), glass (Rs. 1,500-3,000), hardware (Rs. 1,000-2,000), fabrication labor (Rs. 1,500-2,500), and profit margin. Final window price: Rs. 9,000-15,000.
Where can I buy aluminum material in Kathmandu?▼
Major aluminum suppliers in Kathmandu: Balaju Industrial Area, Kalimati area, Teku area. Wholesale rates available for 100+ kg purchases. Retail buyers pay 10-15% more than wholesale. For window/door projects, buying fabricated profiles from window makers is more practical than buying raw aluminum.
Is it cheaper to buy aluminum and make windows myself?▼
No, DIY is not cheaper for most people. You need: cutting equipment (Rs. 50,000+), powder coating facility (Rs. 100,000+), glass cutting tools, welding equipment, expertise. Professional fabricators buy aluminum in bulk (cheaper), have equipment, and expertise. DIY only makes sense for large-scale projects (10+ windows).
