Aluminum Exterior Doors Manufacturer China Factory Price Thermal Break Entry
1. System Overview — The Signature Entry
The Aluminum Exterior Door is the signature element of any facade — engineered for security, thermal performance, and architectural presence. As a premier manufacturer in China, Richocean engineers exterior doors with 6063-T6 thermal break frames, multi-point locking, and Low-E glazing, at factory-direct prices.
2. Core Material Science — 6063-T6 Frames
The frame profile carries the full door and hardware load. Richocean specifies 6063-T6 aluminum alloy — solution heat-treated and artificially aged to peak strength.
Thermal performance comes from the PA66GF25 polyamide thermal break — 25% glass-fiber reinforced nylon, mechanically crimped between inner and outer aluminum shells, with a 34mm depth for entry systems.
3. Thermal Performance — Insulated Entry
Entry doors must resist thermal bridging:
- U-value: 1.6–2.2 W/(m²·K) with thermal break and Low-E glass
- Condensation resistance: warm-edge spacers and polyamide breaks
- Air tightness: triple EPDM sealing around the leaf
4. Security Engineering — Multi-Point Locking
The entry door is the security frontier:
- 7–10 locking points around the leaf perimeter
- Steel-reinforced core: galvanized plate inside the frame
- Forced-entry: RC2/RC3 rated hardware options
5. Finishes & Glazing
Aesthetics are delivered through engineered finishes:
- Wood-grain: sublimation transfer, UV-stable, 10-year warranty
- Low-E glazing: double or triple insulated units
- Laminated option: SGP interlayer for impact resistance

7. Technical FAQ
Q: What is the maximum leaf size for an aluminum exterior door?
A: Typical maximum is 1,400mm wide × 2,800mm high; taller and heavier leaves use reinforced frames and heavy-duty hinges.
Q: Is wood-grain aluminum durable in harsh weather?
A: Yes — the grain is transferred onto powder-coated aluminum; it will not warp, peel, or rot like timber, with 10-year UV warranty.
Q: How many locking points are recommended for security?
A: 7–10 points distributed along the perimeter with a steel-reinforced core and certified cylinder achieve RC2–RC3 burglary resistance.
8. China Market Ranking — Why Richocean is #1
Richocean ranks #1 in China for exterior door export volume. The Foshan factory runs automated CNC machining and powder-coating lines with 80,000m² annual capacity, serving Southeast Asia, the Middle East, and North America. Factory-direct pricing runs 30–50 percent below Western distributors.
