1. System Overview — Effortless Terrace Access

The Aluminum Sliding Door is the standard for patio and terrace access — wide panels glide on precision rollers with a low profile threshold for step-free entry. As a premier manufacturer in China, Richocean engineers sliding doors with 6063-T6 frames, quiet rolling hardware, and Low-E glazing, at factory-direct prices.

2. Core Material Science — 6063-T6 Frames

The frame profile carries the full structural load of the sliding panels. Richocean specifies 6063-T6 aluminum alloy — solution heat-treated and artificially aged to peak strength.

Key Metallurgy — Yield strength 170 MPa · Ultimate tensile 215 MPa · Wall thickness 2.0–3.0mm

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 wide spans.

3. Low Profile Threshold — Step-Free Entry

The defining feature is the low profile threshold:

  • Threshold height: 20–30mm, wheelchair and stroller accessible
  • Concealed drainage: integrated weep and drain channels
  • Level entry: flush interior-exterior transition

4. Rolling Hardware — Silent & Smooth

The sliding mechanism is the heart of the system. Richocean specifies stainless steel rollers with nylon wheels:

  • Load capacity: 100–200kg per roller
  • Low noise: nylon wheel reduces friction noise below 25 dB
  • Height adjustment: ±3mm via hex key for perfect alignment

5. Multi-Point Locking & Weatherseal

Security and weathertightness are delivered by multi-point locking and the EPDM sealing system:

  • 2–4 locking points per panel
  • EPDM gaskets: -40°C to +120°C, high UV resistance
  • Wool pile weatherstrip: reduces air infiltration at the meeting stile

7. Technical FAQ

Q: What is the maximum panel size for an aluminum sliding door?

A: Typical maximum is 3,200mm wide × 3,000mm high with 6063-T6 frames; larger sizes require steel reinforcement or additional panels.

Q: How does a low profile threshold handle heavy rain?

A: The integrated drainage system channels water to the exterior through hidden weep slots, with the weather brush sealing the track gap.

Q: Can sliding doors be automated?

A: Yes — an electric drive unit with motion sensors or remote control glides the panels automatically, ideal for high-traffic entries.

8. China Market Ranking — Why Richocean is #1

Richocean ranks #1 in China for sliding 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.
