Factory-direct OEM/ODM certified fenestration solutions engineered for extreme wind-loads, high thermal efficiency, and contemporary architecture.
The global commercial and high-end residential fenestration markets are undergoing a fundamental transformation. Driven by stringent building energy codes (such as ASHRAE 90.1, IECC, and European EN 14351-1 standards), modern architects and structural engineers demand unprecedented structural stability, minimal sightlines, and superior thermal isolation values (U-factors < 0.28 BTU/h·ft²·°F). As a premiere Foshan-based aluminum window and door manufacturer, Veltor Window & Door Co., Ltd. bridges the gap between raw aluminum metallurgy, mechanical engineering, and high-volume custom manufacturing.
Whether sourcing ultra-slim bi-fold system components, heavy-duty lift-and-slide patio doors, or specialized thermal-break casement windows, B2B procurement professionals must navigate structural deflection tolerances ($I_x$ moment of inertia), atmospheric corrosion mitigation (AAMA 2604/2605 compliant powder coatings), and localized wind-load pressures. This document serves as an exhaustive procurement and engineering guideline for global developers, fenestration importers, and contract builders.
Vertical integration from extrusion matrix design to automated glazing assembly ensures precision, repeatability, and cost efficiency.
We utilize pristine primary aluminum ingots engineered to 6063-T5 and T6 temper specifications. Our wall thicknesses range from 1.6mm for standard windows up to 3.0mm heavy-duty structural sashes, guaranteeing structural integrity against typhoon-level wind pressures.
Thermal conduction through aluminum is eliminated using imported Technoform Polyamide PA66 reinforced with 25% glass fiber. This delivers extraordinary structural rigidity while dramatically reducing thermal transmittance across interior and exterior environments.
Security is paramount. Our doors feature integrated multi-point gearboxes paired with 304/316 grade stainless steel mushroom heads, anti-lift pins, and heavy-duty top-hung hardware capable of supporting panel weights exceeding 400kg.
Configurable with double or triple-pane tempered glass units (IGUs) incorporating Low-E coatings, warm-edge spacers, and Argon gas fills (90%+ concentration). Acoustic dampening ranges up to STC 45dB, isolating high-frequency urban sound.
From initial DWG/BIM structural review to 3D prototype creation, structural calculation validation, and custom extrusion die tooling, our dedicated in-house engineering squad supports end-to-end original equipment manufacturing.
Every fenestration unit undergoes full protective wrapping, protective blue PE tape, high-density foam corner cushions, and custom fumigated plywood crates equipped with steel banding and integrated forklift risers.

As international energy performance standards tighten and architectural design aesthetics lean toward seamless indoor-outdoor transitioning, the manufacture of aluminium folding and sliding doors is experiencing rapid technological evolution:
Essential insights for importers, developers, and commercial contractors negotiating direct factory orders.
Because every architectural opening is tailored according to project-specific engineering drawings, Veltor accepts single-villa project orders starting from 50 square meters. For custom profile extrusion dies or private-label hardware packaging, structural economic thresholds typically begin at 1 Full Container Load (20GP or 40HQ).
Standard non-thermal aluminum is highly conductive, allowing ambient exterior heat or freeze conditions to transfer directly indoors. A thermal-break system splits the internal and external aluminum extrusions using a low-conductive Polyamide PA66-GF25 strip. This structural barrier dramatically lowers overall U-factors, prevents internal condensation, and cuts HVAC energy demands by up to 40%.
Yes. We routinely fabricate systems engineered to specific international standards, including European CE standards (EN 14351-1), North American NFRC thermal ratings, Australian AS2047 wind-load testing, and Florida High-Velocity Hurricane Zone (HVHZ) impact glass requirements. Structural engineering calculations ($I_x$ inertia values) are provided during drawing sign-off.
For standard inland applications, we provide premium electrostatic powder coatings (AAMA 2604). For coastal installations subject to salt spray and high atmospheric humidity, we mandate Fluorocarbon PVDF coatings (AAMA 2605) or deep anodizing (up to 25 microns), backed by 15-25 year surface integrity warranties.
Once shop drawings are formally approved and deposit payments are verified, standard production timelines are 25 to 35 working days. Projects requiring custom color powder coating or non-standard glass units (e.g., smart tintable electrochromic glass) may require 35 to 45 working days.
