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.
