Sliding Patio Door Export from China: Aluminum Sliding Glass Doors Specs & Pricing

1. Frame Profiles and Thermal Break Data

6063-T5 Extrusions, 2.0 mm Wall

The sliding patio door frame is extruded from 6063-T5 aluminum billet with a minimum wall thickness of 2.0 mm on structural members (sash rails, meeting stiles, sill track) and 1.4 mm on non-structural trim. Tensile strength is 160 MPa minimum, yield 110 MPa minimum. Sash depth is 100 mm for the 2-track system and 165 mm for the 3-track system; both accept glass from 20 mm to 32 mm overall thickness. Each sliding sash runs on two stainless steel tandem rollers rated at 120 kg per pair, adjustable plus/minus 5 mm in height from the interior face.

Thermal Break and Surface Finishes

The thermal break is a 24 mm PA66 GF25 polyamide strip (glass-fiber reinforced, C-shaped) rolled into the inner and outer extrusions. Frame U-value measured per NFRC 100 is 2.2 W/m2K for the 2-track frame and 2.4 W/m2K for the 3-track frame. Standard finishes: powder coating to AAMA 2604 (60 micron film, 10-year color warranty, RAL or wood-grain sublimation), or PVDF to AAMA 2605 (2-coat, 70 percent Kynar resin) for coastal and high-UV states. Anodized finish at 15-20 micron is available for commercial storefront-adjacent projects.

2. Sliding Glass Doors: Glazing Options and NFRC Ratings

Standard Glazing Build-Ups

All sliding glass doors ship with tempered safety glass to ANSI Z97.1 / CPSC 16 CFR 1201 (Category II) as standard. The three volume build-ups below cover 90 percent of North American orders; center-of-glass values are per NFRC 100/200 simulation with a warm-edge spacer and 90 percent argon fill.

ENERGY STAR Version 7.0 Zone Compliance

ENERGY STAR 7.0 (effective October 2023) requires doors to meet U-factor and SHGC limits that vary by climate zone. A patio door is classed as a door when glazing exceeds 50 percent of the area, which applies to all configurations on this page. The double-silver low-E build-up satisfies the Northern zone; the single-silver build-up satisfies the Southern zone. For the Northern zone, the 0.30 U-factor build-up with SHGC 0.27 passes because the SHGC limit in that zone is 0.40 with a U-factor trade-off path.

Buyers comparing total door budgets can cross-check against the patio doors wholesale supply page for mixed-container consolidation with French and folding doors.

4. Aluminum Sliding Door Configurations and Track Design

Standard vs Lift-and-Slide Mechanics

The standard aluminum sliding door runs the sash directly on tandem rollers with a brush-seal perimeter; maximum sash weight is 240 kg and maximum sash size is 1.8 x 2.6 m. The lift-and-slide system raises the sash 6 mm onto its rollers when the handle rotates 180 degrees, compressing a continuous EPDM gasket in the closed position. Air infiltration on the lift-and-slide is 0.06 cfm/ft2 at 75 Pa versus 0.15 cfm/ft2 on the standard system, which is why lift-and-slide is the default recommendation north of climate zone 5 and for any sash wider than 1.5 m.

Panel Arrangements by Opening Width

Heavy or oversize sashes (above 240 kg, above 3.0 m height) move to the heavy-duty platform with 3.0 mm wall profiles and quad rollers; see the heavy-duty aluminum sliding doors page for that system’s load tables.

5. Sliding Glass Doors Exterior: Standard North American Sizes

Rough-Opening Chart (Imperial)

Sliding glass doors exterior orders from US and Canadian dealers follow imperial rough openings. The table below maps the six highest-volume call-outs to frame sizes and panel splits. Frame size equals rough opening minus 12 mm on width and 6 mm on height for shim space.

Custom Sizes and Tolerances

Any width from 1.2 m to 12 m and height from 1.9 m to 3.0 m can be produced without tooling charges. Manufacturing tolerance is plus/minus 1.5 mm on frame diagonals. Heights above 2.6 m automatically move to the 2.5 mm wall sash and double-silver low-E is replaced by heat-strengthened laminated on the exterior lite when the glass area per lite exceeds 3.6 m2, per ASTM E1300 load calculations.

6. Patio Sliding Door for Hurricane Zones (HVHZ)

Miami-Dade NOA and Florida Product Approval

For High-Velocity Hurricane Zone counties (Miami-Dade, Broward) the patio sliding door is supplied under a Miami-Dade NOA with the following test evidence: large and small missile impact per TAS 201/203, cyclic wind pressure per TAS 203, and uniform static air per TAS 202. The impact build-up is 8 mm tempered + 16 mm argon + 5+1.52PVB+5 laminated low-E, with a reinforced 3.0 mm interlock and stainless steel anti-lift blocks every 600 mm.

Non-HVHZ Coastal Orders

Outside HVHZ counties, most Gulf and Atlantic coast projects specify DP50 with the standard laminated build-up (5+12A+5 laminated inner) rather than the full NOA package; this keeps the surcharge at USD 18-24/m2 instead of USD 38-52/m2. Texas Windstorm (TDI) jurisdictions accept AAMA 101 DP50 test reports with an engineer’s shop-drawing stamp, which ROGENILAN supplies with the submittal package.

7. Certifications and Lab Test Data

Packing and Container Loading

9. Installation and Flashing Sequence

Step Sequence (ASTM E2112 Method B)

• 1. Verify rough opening plumb/level within 3 mm over 2.4 m; check diagonal within 4 mm.
• 2. Apply self-adhered flashing membrane to the sill pan, upturned 100 mm at jambs; install sloped sill pan with back dam.
• 3. Set the KD frame on composite shims at 300 mm centers; anchor jambs at 150 mm from corners and 450 mm centers with corrosion-resistant screws.
• 4. Lap jamb flashing over the frame flange, then head flashing; integrate with the WRB in shingle fashion.
• 5. Hang fixed panel first (exterior track), then sliding panel; adjust tandem rollers until the sash reveals are even within 2 mm.
• 6. Backer rod and ASTM C920 Class 25 silicone sealant at the interior perimeter; leave the sill drainage path open.
• 7. Water-test the sill at 2 L/min for 15 minutes before interior trim; adjust the interlock bumpers and verify lock throw.

Commissioning Checks

Sliding force should read 40-60 N at the handle on a 240 kg sash after roller adjustment. Air-seal the meeting stile by compressing the fin-seal bumpers until the interlock gap closes to 4 mm. For lift-and-slide units, cycle the handle 20 times before handover and confirm the sash drops fully onto the gasket; an unseated sash is the number one cause of air-leakage callbacks.

10. Case Study: 48-Home Subdivision in Houston, Texas

Scope and Configuration

A production builder sourced all rear-elevation patio doors for 48 single-family homes in a Houston subdivision. Scope: 48 units of 6-0 x 6-8 OX 2-panel and 96 units of 8-0 x 8-0 OXO 3-panel, thermal-break frames in bronze AAMA 2604 powder coat, single-silver low-E glass with SHGC 0.25 solar-control variant (Southern zone), standard DP50 (non-HVHZ Harris County), retractable screens on all OX units. Total door area: 694 m2 in three 40 HQ containers.

Result and Schedule

Landed cost came to USD 121,900 versus the local dealer quote of USD 289,300, a saving of 57.9 percent. Schedule: drawings approved day 7 after deposit, production 34 days, ocean transit 29 days, customs clearance 4 days. Two sashes arrived with scratched stiles (0.7 percent of panels) and were replaced from the spare-parts allowance plus a couriered replacement within 12 days under the project warranty.

11. Aluminum vs Vinyl vs Wood-Clad Patio Doors

Measured Comparison

When Each Material Wins

Vinyl leads on frame U-value and first cost in mild climates, but its thermal expansion (2.6x aluminum) causes sash binding on wide panels and it cannot be produced beyond 1.2 m sash width. Wood-clad leads on interior aesthetics at 3-5x the landed cost and requires refinishing cycles in humid climates. Thermal-break aluminum is the only option that holds DP50+ at sash widths above 1.5 m, which is why production builders and multi-family projects use it for 8 ft and wider openings. Buyers speccing full window-and-door packages can review the same comparison on the aluminium windows and doors wholesaler page, and for all-glass front elevations the glass door wholesale page covers frameless-adjacent options.
