60E High-Efficiency Casement Window (20 mm break)

Technical Data & Specification Review

Published parameters are reference configurations for this series. Final values are subject to approved drawings, manufacturer technical documents, samples and project inspection records.

Dimensional and performance figures are taken from the manufacturing partner’s own product catalogue. Mill certificates, spectrometer analysis reports and coating thickness records are issued with each shipment.

What we can change for your project – and what we cannot

Material and Grade

Sections are extruded in 6063-T5, 6005-T5 or 6061-T6 depending on the load path – the lighter architectural members in 6063-T5, load-carrying members in 6005-T5, and the highest-stress components in 6061-T6. Billet is sourced from major domestic smelters with per-heat spectrometer verification, and ageing is controlled in gas-fired double-door ovens.

Surface Finish

Anodising, powder coating, fluorocarbon (PVDF) coating, electrophoretic lacquer and wood-grain heat transfer are all available, all in-house, all ahead of a chromium-free pre-treatment stage. Because extrusion, crimping and coating happen on one site, a mixed-finish order for a single project stays on one production schedule instead of being split across subcontractors.

Custom Tooling

Bespoke tooling is part of the offer, not an exception to it. Die design uses simulation analysis and virtual manufacturing, dies are cut on site and hardened in a vacuum nitriding furnace, and customers’ own drawings are accepted directly. Existing dies in the 5,000-plus item library can also be adapted for a project-specific variant.

Made-to-Order Sizing

Made to order means made to your figures – cut length, wall thickness inside the section’s design envelope, finish colour and bundle quantity. Supplying the cutting list with the order costs nothing and saves both the offcut waste and the saw time at the other end.

Factory and Export Capability

Shipping is handled by the factory itself, which holds a direct export licence for aluminium and aluminium products. The plant runs 375 staff including 45 technical personnel across three in-house laboratories. Packing for export uses protective film, moisture barrier, foam interleaving and timber crating, with FOB, CIF and DDP all available.

Extrude, Then Finish

The confirmed alloy and temper go through the press, then through whichever finish was agreed – anodising, powder, PVDF, electrophoresis or wood-grain transfer – matched to the approved colour panel.

Packed for the Voyage

Protective film, moisture-barrier wrap, foam between profiles and timber crates, loaded into the container under our own supervision, on FOB, CIF or DDP terms.

The full range sits under Door & Window Profiles, and the buildings and sites these products have gone into are listed under Domestic Engineering Projects. If none of them is quite your specification, say what is different in the enquiry – most of what we ship is made to a drawing rather than picked off a shelf.
