In 1994, Jia Hua Aluminum was established in Foshan, China. With the rapid growth development, our company becomed one of the leading aluminum extrusion factories in China.We commit to satify with our customers by contributing of high quality and good service .Our development by pursuing the contribution of high quality and high service. We respect, trust, and cooperate with customers to achieve higher value for each other.
Precision Engineering from the Start. Our in-house design team specializes in converting your complex CAD drawings into high-performance extrusion dies. With over 20 years of experience, we optimize profiles for structural integrity and material efficiency, ensuring even the most intricate geometries are realized with micron-level accuracy.
The Right Material for the Right Application. We offer a comprehensive portfolio of aluminum alloys, including 1000, 3000, 5000, 6000, and 7000 series. Whether you need the superior thermal conductivity of 6063 for heat sinks or the high structural strength of 7075 for aerospace components, we provide the exact chemical composition and temper (T5/T6) to meet your specs.
Beyond Extrusion: Ready-to-Assemble Components. Jiawah provides full-scale secondary fabrication to deliver finished parts directly to your assembly line. Our advanced CNC center handles precision cutting, 5-axis milling, drilling, tapping, and punching. We eliminate your supply chain complexity by handling everything from the raw profile to the final component.
Durability Meets Aesthetic Excellence. Protect and enhance your products with our world-class surface treatment options. From high-micron anodizing for superior corrosion resistance to premium powder coating in any RAL color, we ensure your profiles withstand harsh environments while maintaining a flawless finish. Electrophoresis, brushing, and wood grain textures are also available.
Expert review of your CAD drawings with DFM feedback to ensure structural integrity and optimize material costs for efficient manufacturing.
Precision die development and rapid prototyping within 15-20 days, ensuring the first article meets your exact tolerances and quality standards.
Scalable extrusion and advanced fabrication under strict ISO 9001 protocols, including rigorous testing to guarantee consistency across every single batch.
Safe packaging and coordinated international shipping, delivering finished components directly to your facility with comprehensive quality inspection and compliance reports.
Empowering your innovation with 20+ years of engineering expertise. Whether it’s complex geometries or ultra-tight tolerances, we turn your CAD drawings into high-performance components.
Standard profiles lead to leaking windows and structural failures. Here is how JH Aluminium solves the 4 critical pain points of window & door manufacturers worldwide.
01
We integrate world-class Polyamide 66 gigafrost insulation strips into multi-chamber profiles, lowering U-values down to 1.0 - 2.0 W/m²K.
02
Our automated pre-treatment and vertical coating lines deliver a 10-25μm anodized layer or AkzoNobel coatings, backed by a 20-year weatherability warranty.
03
Extruded with premium 6063-T5/T6 billets, our profiles maintain geometric tolerances up to ±0.1mm, ensuring seamless corner-joint crimping.
04
We design and CNC-machine custom dies in-house within 10-15 days. Tooling costs are 100% refundable upon target bulk order volume.
From ISO quality systems to SGS material testing, our commitment to excellence is verified by world-leading authorities, ensuring your peace of mind in every coil.
At JH Aluminium, structural integrity for high-rise systems is determined by precision engineering. We primary utilize heavy-duty 6063-T6 or 6005A-T6 aluminum alloys, which deliver significantly higher yield strength compared to standard T5 tempers.
During the custom drawing review stage, our engineers conduct finite element analysis (FEA) to optimize wall thickness distributions (up to 3.0mm for heavy-duty sliding doors) and internal chamber geometry. This ensures our window and door profiles comfortably comply with international structural standards, such as Australia’s AS2047 and North America’s AAMA, resisting extreme wind loads in coastal or typhoon-prone regions.
Yes, our bespoke thermal break systems are engineered specifically to surpass global energy efficiency mandates. We integrate genuine Technoform Bautec® or high-grade PA66GF25 (Polyamide 66 reinforced with 25% fiberglass) thermal insulation strips into a multi-cavity profile design.
By isolating the exterior and interior aluminum sections, our systems drastically cut thermal bridging. This allows window manufacturers to achieve exceptionally low U-values ranging from 1.0 to 2.0 W/m²K (depending on the glazing configuration), seamlessly passing local green building compliance audits and reducing building HVAC energy consumption by up to 30%.
For coastal zones exposed to high salinity or regions with extreme UV exposure, we provide two ultra-durable, premium finish options:
Qualicoat Standard Powder Coating: Utilizing world-class powders from AkzoNobel (Interpon) or PPG, we apply a uniform vertical coating that resists chalking, peeling, and color fading.
Architectural Anodizing (Class 20-25μm): This chemical process creates a dense aluminum oxide layer integrated with the metal itself, providing unrivaled resistance to salt-spray corrosion.
Both premium finishes are backed by an official 20-year weatherability warranty, ensuring the window frames retain their pristine aesthetic without rusting.
Our vertically integrated, in-house precision tooling center allows us to deliver custom window and door dies faster than standard industry timelines:
Die Design & Fabrication: 10 to 15 working days from CAD drawing sign-off.
Sample Extrusion & Testing: 3 to 5 days, including strict mechanical and dimensional tolerance audits.
We provide a highly competitive upfront tooling fee based on profile weight and complexity. To support our long-term B2B partners, 100% of the custom tooling fee is fully refundable once your cumulative bulk order volume reaches a predefined threshold (typically 3 to 5 tons per die).
Leaking windows are usually caused by profile distortion and wide manufacturing tolerances. JH Aluminium eliminates this risk by maintaining strict geometric tolerances up to ±0.1mm, which is far tighter than the standard GB/T 14846 high-precision level.
We check alloy consistency during billet casting and monitor extrusion speeds with automated infrared sensors to prevent warping. This extreme dimensional precision ensures that when your fabrication shop cuts the profiles at 45° or 90°, the miter joints and internal corner cleats crimp flawlessly. The result is a seamless, airtight, and watertight perimeter seal across the entire window frame.
