Note: NFRC values (U-Factor / SHGC / VT) vary with glazing configuration and size. Please fill them in according to the actual certification report before publishing.

Materials & Finish

Material Composition:

• Profile — 6060-T6 aluminum alloy (GB/T 5237) with PA66 GF25 nylon thermal break strips, 3–5 chamber design
• Glass — float glass base + Low-E coating, argon-filled insulated glazing; optional tempered / laminated for safety
• Hinges & Hardware — heavy-duty stainless steel hinges (load ≥80kg per leaf), multi-point locking system
• Seals — EPDM weather strips (double seal), UV-resistant, −40°C to +120°C working range
• Threshold — extruded aluminum with thermal break; optional low-profile threshold with drainage cover

Surface Finishes:

• Powder Coating — ≥60μm film thickness, salt spray 1000h+, 15+ RAL colors, 10-year color warranty
• Anodizing — 15–20μm film, excellent weatherability for coastal areas
• Wood Grain Transfer — realistic wood texture, perfect for French-style interior / exterior matching

Manufacturing Process:

Double-head profile cutting → corner crimping with injected sealant (corner cleats + two-component adhesive) → mullion / grid assembly → hinge and locking-point adjustment → glass glazing and sealing → three-stage quality control (incoming inspection / in-process inspection / outgoing inspection).

Assembly & Installation

Installation Steps:

• Step 1 — measure the door opening, verify level and plumb, and allow a 10–20mm installation gap
• Step 2 — clean the opening and fix the frame (expansion bolts / fixing brackets at ≤600mm spacing); apply waterproofing at the threshold
• Step 3 — after leveling and plumbing the frame, fill the frame-to-wall gap with expanding foam and seal the outside with weather-resistant sealant
• Step 4 — install the door leaves and heavy-duty hinges, adjust hinges and locking points so both leaves close tightly and operate smoothly
• Step 5 — carry out a water spray test plus opening / locking checks; remove the protective film after acceptance

Use & Maintenance Recommendations:

• Clean profiles and glass regularly with water or a mild neutral cleaner; avoid strong acids and alkalis
• Apply grease to hinges and locking points every six months to keep operation smooth
• Keep threshold drainage holes clear; check gaskets for ageing and replace when necessary
