Custom OEM Aluminum Windows Suppliers & Exporter

For custom proprietary profile shapes, our standard die development threshold is 3 metric tons per profile section. If initial trial orders do not reach 3 tons, a nominal die tooling fee is charged, which is fully refunded once cumulative order volume reaches the 5-ton milestone.

While uPVC offers low base material conductivity, its flexural modulus is significantly lower than aluminum ($E_{\text{PVC}} \approx 3 \text{ GPa}$ vs. $E_{\text{Al}} \approx 69 \text{ GPa}$). Aluminum extrusions with PA66-GF25 thermal breaks withstand far higher wind loads (DP ratings up to DP80 or 5500 Pa) without structural steel inserts, enabling larger sash dimensions, slimmer frames, and longer service life (30+ years without thermal degradation or color fading).

Yes. We regularly manufacture window and door assemblies tested to AS2047 (including deflection, air infiltration, water resistance, and ultimate strength tests) and NFRC/AAMA protocols. We provide certified laboratory test reports (Intertek/Azuma) and sticker certifications for smooth customs clearance and building inspector sign-off.

Our OEM production lines integrate premium European hardware platforms including German Siegenia, G-U (Gretsch-Unitas), Roto Frank, and Hoppe handles, as well as customized heavy-duty Kinlong and KWI systems. We also support customer-nominated hardware integration for specific regional hardware standards.

All finished window units undergo protective film wrapping, corner protective sleeve installation, and custom fully-enclosed fumigated plywood crate packaging with internal foam cushioning. Crates are engineered with forklift slots and top-load structural reinforcement, maintaining a zero-damage rate across container sea freights.

For installations within 1.5 km of marine coastlines, we specify Fluorocarbon PVDF coating (minimum 3-coat system, $\ge 40 \mu m$ thickness) complying with AAMA 2605 or Qualicoat Class 3 Anodizing ($\ge 25 \mu m$ layer depth). This prevents pitting corrosion, salt fog deterioration, and gloss reduction caused by harsh maritime UV exposure.

Standard architectural finishes (powder coat white/black/grey) carry a 20–25 day production cycle following shop drawing sign-off. Specialty finishes such as wood grain sublimation, anodizing, or custom RAL color matching require 30 days. Emergency fast-track scheduling is available for critical commercial construction deadlines.
