Which aluminium alloys and tempers does Pak Alumex extrude?

Our architectural range is extruded primarily in 6063 alloy, supplied in T5 and T6 tempers. 6063-T5 is used for standard window, door and partition profiles, while T6 is specified where higher yield strength is required for curtain wall mullions, louver blades and long-span members.

What film thickness do you apply for powder coating and anodizing?

Architectural powder coating is applied at a typical dry film build of 60–80 microns over a chromate-free pre-treatment, in line with Qualicoat-style practice. Anodized finishes are produced from 10 microns for interior use up to 20–25 microns for exterior facade exposure.

Can Pak Alumex produce custom dies and bespoke profiles?

Yes. We develop project-specific dies from DWG/DXF sections or physical samples. Our engineering team reviews wall thickness, tolerance, extrusion ratio and press capability before die manufacture, then supplies first-article samples for approval prior to bulk production.

Do you supply thermally broken aluminium profiles?

Yes. Thermally broken systems use polyamide strips mechanically crimped between inner and outer aluminium shells, reducing conductive heat transfer through the frame and improving condensation resistance for double-glazed windows, doors and curtain walls.

How do you support overseas buyers and contractors?

Overseas purchasers receive profile drawings, weight-per-metre schedules, finish samples and packing specifications before shipment. Orders are bundled with interleaved protective film, strapped in wooden crates or bundles, and documented for export from Karachi port with full commercial and quality paperwork.

Tropical Facade Thermodynamics: Solar Geometry & OTTV Optimization in Kuala Lumpur

Kuala Lumpur operates under an equatorial climate positioned at Latitude 3.1390° N, characterized by high diffuse and direct horizontal solar irradiance averaging 4.5 to 5.5 kWh/m²/day, intense relative humidity (>80% RH year-round), and violent equatorial thunder squalls. Under these environmental parameters, unshaded glass facades on high-rise commercial structures act as continuous heat sinks, drastically elevating air conditioning loads and thermal discomfort.

To meet Malaysia’s stringent building code standard—MS 1525:2019 (Code of Practice on Energy Efficiency and Use of Renewable Energy for Non-Residential Buildings)—architects must limit the building envelope's Overall Thermal Transfer Value (OTTV) to below 50 W/m². Custom OEM extruded aluminium solar shading systems represent the most mechanically sound and architecturally versatile passive strategy to cut solar radiation before it penetrates the thermal envelope.

The mathematical calculation of facade OTTV relies directly on solar heat gain control:

OTTV = 15(1 - WWR)U_w + 6(WWR)U_g + (194 × CF × WWR × SC)

Where WWR represents the Window-to-Wall Ratio, CF is the Solar Solar Solar Solar Solar Solar Solar Solar Solar Solar Solar Solar Solar Solar Solar Solar Solar Solar Solar Solar Solar Solar Solar Solar

By implementing custom-engineered aerofoil sunshade fins (such as 150mm, 200mm, and 300mm extruded profiles), our systems drop the Shading Coefficient of glass assemblies from an unshaded 0.72 down to an impressive 0.22 - 0.35. This drastic thermal mitigation reduces air conditioning energy load by up to 32% annually, making direct contribution toward achieving Gold and Platinum ratings under Malaysia's Green Building Index (GBI).

Motorized & BMS-Integrated Kinetic Louvers

Developers in KL are rapidly shifting toward motorized sunshades connected to Building Management Systems (BMS). Using real-time solar tracking sensors, blades dynamically tilt to optimize indoor daylighting while rejecting maximum solar heat load throughout the day.

Low Embodied Carbon Recycled Billets

With corporate ESG reporting mandating lower Scope 3 emissions, our factory offers aluminum extrusions produced using recycled industrial scrap and low-carbon primary aluminum billets, offering up to 70% lower embodied carbon per metric ton.

Sublimation Wood Grain Replacing Timber

Procurement & Technical FAQ

Frequently Asked Questions by Kuala Lumpur Architects & Contractors

Clear engineering and logistics guidance for importing custom OEM aluminium shading systems into Malaysia.

How do your custom solar shading systems comply with Malaysia's MS 1525 energy standard?

Our custom aerofoil louvers and exterior sunshade profiles are designed to drop the facade’s Shading Coefficient (SC) down to between 0.22 and 0.32. By cutting solar heat gain prior to the glass surface, our profiles directly reduce the Overall Thermal Transfer Value (OTTV) to well under the 50 W/m² limit prescribed by MS 1525:2019, securing vital points for GBI (Green Building Index) certification.

What surface finish is recommended for high-humidity and high-pollution environments like Kuala Lumpur?

We strongly recommend 70% Kynar 500 PVDF (Fluorocarbon 3-coat system, minimum 40 µm thickness) or Qualicoat Class 2 Superdurable Architectural Powder Coating (60-80 µm). Both systems provide exceptional resistance to humidity, color fading, chemical atmospheric pollutants, and acid rain, backed by a 20 to 25-year warranty against chalking and peeling.

Can your factory produce custom extrusions based on DWG/DXF architectural CAD drawings?

Yes, we specialize in 100% custom OEM production. Send your DWG/DXF cross-sectional drawings, and our structural engineering team will review wall thickness, extrusion ratios, and alloy suitability. Once verified, custom die manufacturing takes 7 to 10 days, followed by sample extrusion approval before mass production starts.

What is the typical shipping lead time and customs process to Port Klang?

Production turnaround for custom extrusions and surface finishing is typically 15–20 days. Container sea shipping from our export port to Port Klang (Westport/Northport) takes approximately 10 to 14 days. We provide full commercial documentation, packing lists, Certificate of Origin (Form E for ASEAN tariff reduction), and mill test certificates for seamless Malaysian Customs clearance.

How do your louver profiles perform under tropical storm and high wind conditions?

Our high-rise shading profiles are extruded using high-yield 6063-T6 or 6061-T6 temper aluminum, engineered to withstand wind loads up to 4.5 kPa in accordance with MS 1553 (Code of Practice on Wind Loading for Building Structures). We provide structural deflection analysis and finite element modeling (FEM) for custom project submittals.

Do you supply complete ready-to-install sunshade kits or raw extrusion lengths?

We offer both! We supply standard 6-meter mill finished or coated profile lengths for local Malaysian fabricators, as well as fully CNC precision-machined, pre-drilled, notched, and bracketed ready-to-assemble OEM systems complete with EPDM gaskets and stainless steel fasteners.
