Getting Aluminum Windows and Doors Quotes from China in the Philippines

The Reality of Getting Aluminum Windows and Doors Quotes in the Philippines

After dealing with multiple suppliers and comparing three different quotations for the same project, here’s what you actually need to know about getting aluminum windows and doors quotes. Most advice online glosses over the real complexity - this won’t.

Before diving into the quotation process, ensure you’re working with verified suppliers by reviewing our Chinese aluminum supplier directory with typhoon-certified manufacturers.

The Quote Confusion: What You’re Actually Comparing

Not all aluminum series are the same. Suppliers will quote you different series without explaining the differences, making price comparisons meaningless.

From my quotations:

125-70 Series: Standard thermal break, 1.5mm thickness
110 Ultra-Narrow Series: Thicker profiles (1.8mm), minimal visible frames
116-76 Series: Heavy-duty for doors, 2.5mm thickness

The price difference? Ultra-narrow series runs about 15-20% more, but the visual impact is significant. Wide frames make your house look dated before you finish building, if that is important to you.

Glass Specifications: Where They Hide Costs

The Marketing vs Reality

Suppliers love throwing around terms like “triple layer tempered glass” and “LOW-E coating.” Here’s what actually matters:

Glass Configuration That Works:

5mm clear glass + 1.14PVB + 5mm clear glass + 12A Argon gas + 5mm LOW-E clear glass
Total: Triple layers with proper insulation

What Changes Your Quote:

PVB thickness: 0.76mm vs 1.14mm affects safety and price
Argon spacing: 12A, 19A, 20A, or 25A affects insulation
LOW-E coating: Mandatory for energy efficiency, standard on quality windows

The difference between basic and premium glass configuration can add $50-100 per square meter.

Hardware Quality: The Hidden Cost Multiplier

Brand Hierarchy (From My Quotes)

CHINA Brand - Basic, functional, budget option
KINLONG Brand - Mid-range, reliable
HOPO Brand - Premium, heavy-duty (used on sliding doors)

Reality Check: Hardware determines how your windows operate daily. Cheap hardware means sticky operations, adjustment issues, and early failures.

For sliding screens:

Diamond mesh (0.8mm): Standard for windows
HD Mesh Screen: Premium for doors
Fly Screen (nylon): Basic for awning windows

Coating Types: The Durability Decision

Fluorocarbon vs Powder Coating

From supplier discussions:

Fluorocarbon coating: Premium, weather-resistant, maintains color
Powder coating: Standard, various colors available, less durable

The price difference is minimal ($20-30 per window), but durability difference is significant. In Philippine weather, fluorocarbon coating prevents color fading and chalking.

Color Options Available: The suppliers showed the same color chart - brown wood, golden yellow, red wood, white, gray, champagne, chocolate, pure white, matte gray, matte black.

Series Comparison: What The Numbers Actually Mean

Frame Visibility Impact

Standard Series: Thicker frames, visible structure, traditional look
Ultra-Narrow Series: Minimal frame visibility, modern aesthetic, maximum glass area

Strength vs Aesthetics

125-70 Series (1.5mm): Standard residential, good for most applications
110 Ultra-Narrow (1.8mm): Premium residential, better strength-to-visibility ratio
116-76 Series (2.5mm): Heavy-duty for large doors and commercial applications

Quotation Red Flags I Encountered

Process Issues

Suppliers who can’t provide complete quotes - One supplier needed multiple follow-ups for missing door schedules
Mixing standard and premium without explanation - Same supplier quoted different glass thicknesses without noting the change
Hardware brand switching - Different brands for different products without price justification

Price Structure Problems

No clear series differentiation - Quotes that don’t specify which aluminum series
Glass specification vagueness - “Triple tempered glass” without PVB and spacer details
Missing installation scope - EXW pricing without local handling costs

What Actually Affects Your Final Cost

Size vs Complexity

From the quotes, cost per square meter varies dramatically:

Small windows (1.1-2.4 sqm): $271-621 per sqm
Large windows (8.5-11.5 sqm): $108-165 per sqm
Sliding doors: $303-333 per sqm

Why? Fixed costs (hardware, frames, manufacturing setup) spread across larger areas.

Configuration Impact

Fixed windows: Cheapest per sqm (no hardware)
Sliding windows: Mid-range pricing
Awning windows: Premium due to hardware complexity
Sliding doors: Highest absolute cost due to size and heavy-duty requirements

The Real Delivery Timeline

Standard Promise: 30 days after deposit Reality: Add buffer time for:

Architectural drawing approvals
Color confirmations
Hardware specification finalization
Shipping delays (especially for custom sizes)

One supplier revised quotes three times during our process. Plan accordingly.

EXW vs Delivered Pricing

EXW (Ex Works) means you handle:

Shipping from factory to port
Import duties and taxes
Local transportation
Unloading and installation

From quotes: Additional costs include $1,074-1,146 for plywood box packing, plus all logistics.

Practical Buying Strategy

Before Requesting Quotes

Complete architectural drawings - Suppliers can’t quote accurately from sketches
Decide on series preference - Standard vs ultra-narrow affects entire quote structure
Color selection - Some colors may have longer lead times

When Comparing Quotes

Verify aluminum series consistency across all suppliers
Check glass specifications match - PVB thickness, spacer size, LOW-E coating
Confirm hardware brands - Don’t accept “equivalent” substitutions (see our hardware comparison guide)
Compare coating types - Fluorocarbon vs powder pricing

Red Flag Questions

“Can you specify the exact aluminum series for each product?”
“What’s the PVB thickness and argon spacer size?”
“Which hardware brand for each window type?”

If they can’t answer specifically, find another supplier. Is your supplier a middle man? Or is he manufacturing?

The Bottom Line

Aluminum window and door quotes are complex because every component affects cost and performance. Suppliers who oversimplify are either hiding something or don’t understand their own products.

Focus on:

Consistent aluminum series
Proper glass configuration (5+1.14PVB+5+12A+5 LOW-E minimum)
Quality hardware brands (KINLONG or better)
Fluorocarbon coating for durability, see the article on fluorocarbon vs powder coating if you are near the coast
Complete scope definition including installation

Price Reality: Budget $200-400 per square meter for quality windows delivered and installed. Doors run $300-500 per square meter depending on size and complexity.

The cheapest quote will likely become the most expensive mistake. Focus on finding suppliers who can explain their specifications clearly and provide consistent, detailed quotes.
