In-House Manufacturing Advantage
We manage the entire process from extrusion to finishing within our own factory. This vertical integration means we have absolute control over quality standards and production schedules, eliminating delays and inconsistencies.
Result: High-quality aluminum profiles delivered in 15-20 days.
Empowering your innovation with 30+ years of engineering expertise. Whether it’s complex geometries or ultra-tight tolerances, we turn your CAD drawings into high-performance components.
Send us your drawings or samples. Our engineering team provides free DFM (Design for Manufacturability) feedback to optimize your design for cost and performance.
We open new molds in our own workshop. This ensures fast turnaround and easy modification if adjustments are needed.
We extrude samples for your testing. We only proceed to mass production after receiving your written approval.
From extrusion to surface finishing (Anodizing/Powder Coating), all processes are controlled internally. This guarantees stable quality and on-time delivery.
Customized protective packaging ensures your goods arrive safely. Full inspection reports provided before shipment.
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.
The Problem: Cheap profiles lead to high energy consumption, failing strict local building energy codes (like European energy standards or Australia’s NCC).
We integrate world-class Polyamide 66 gigafrost insulation strips into multi-chamber profiles, lowering U-values down to 1.0 – 2.0 W/m²K.
Poorly treated aluminum chalks, bubbles, and corrodes within 3-5 years under high UV exposure or seaside salt-fog environments.
Our automated pre-treatment and vertical coating lines deliver a 10-25μm anodized layer or AkzoNobel coatings, backed by a 20-year weatherability warranty.
Inconsistent wall thickness and twist tolerances cause miter joints to misalign, leading to air/water leakage in finished windows.
Extruded with premium 6063-T5/T6 billets, our profiles maintain geometric tolerances up to ±0.1mm, ensuring seamless corner-joint crimping.
Traditional extruders charge huge upfront die fees and take 45+ days to deliver custom profile samples, stalling your project timelines.
We design and CNC-machine custom dies in-house within 10-15 days. Tooling costs are 100% refundable upon target bulk order volume.
At Jiawah 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.
Expect creative solutions, clear communication, and results tailored to your vision when working with us.

From alloy selection to custom coatings, our expert team provides full-lifecycle support, reducing your hidden operational costs.
15 automatic coating lines with precision testing guarantee ΔE < 1.0 color consistency across batches for a flawless visual finish.
Our 3-coat 3-bake PVDF technology provides a 20+ year warranty against fading and chalking, preserving the asset's value.
Full compliance with ASTM, SGS, and ISO standards grants you seamless access to high-end global infrastructure projects.
100,000 tons annual output and 8,000 pieces daily capacity enable rapid delivery, helping you capture market opportunities faster.
Small suppliers with limited capacity face high risks; a single shutdown could stall your project indefinitely, leading to massive liquidated damages.
Batch-to-batch color shifts from poor anodizing and coating cause high rejections, expensive rework, and profit‑cutting delays—avoid both with our strict process control.
Cheap coatings peel or fade in 2-3 years; the replacement cost will be 5 to 10 times your initial procurement price.
Excessive lead times allow competitors to strike first, putting you at high risk of losing key clients and market share.
Without certified quality, your materials may face customs seizure, legal lawsuits, or even catastrophic structural failures.
Buying without professional guidance leads to incorrect specifications, material waste, and fabrication failures—all at your expense.
