When planning a construction or renovation project, knowing your aluminum window and door delivery timeline is essential for keeping everything on schedule. At ALPES, a leading casement window manufacturer based in Foshan, China, we understand that reliable lead times mean the difference between a smooth project and costly delays. In this guide, we break down everything you need to know about our production timelines, the factors that influence delivery, and how we keep your project on track.
For most standard projects, ALPES delivers finished aluminum windows and doors within 30 to 40 days from the date of drawing approval and deposit receipt. This timeframe covers the full production cycle — from material preparation and profile cutting through final quality inspection and packaging.
Our 100,000 m² manufacturing facility, spread across two production centers in Foshan and Zhaoqing, gives us the capacity to handle both small residential orders and large-scale commercial projects without compromising on quality or timeline.
Quick Reference: Typical Lead Times by Product Type
Understanding the stages of production helps you plan effectively. Here is what happens after you approve your shop drawings:
We source 6060-T66 grade aluminum profiles — the same premium grade used across our entire product line — along with PA66GF25 thermal break strips, insulated glass units, and hardware from our trusted partners including ROTO, Winkhaus, CMECH, and Wehag. Standard materials are kept in stock for faster turnaround, while custom color finishes or specialty glass may add a few extra days to this phase.
Precision CNC cutting machines shape each aluminum profile to exact dimensions. Our fabrication team handles mitering, drilling, milling, and corner assembly. For products like our AW90 Passive Window with K-values as low as 1.3, extra care is taken during multi-chamber thermal break strip insertion to ensure optimal insulation performance.
Our standard color options — Ice Cream White, Aurora Gray, Starry Sky Gray, and Brown Coffee — move through the powder coating line on regular batch schedules. Custom RAL color matching is also available and typically adds 3 to 5 additional days to the finishing stage.
Insulated glass units are installed and sealed using injection-molded structural adhesive for a monolithic, weathertight bond. Hardware is fitted and tested — including multi-point locking systems, hinges, and handles. As a reputable aluminum sliding window supplier, we pay special attention to pulley systems and track alignment on sliding window and door models to ensure smooth, quiet operation for years to come.
Every unit undergoes rigorous inspection before it leaves the factory. Our QC process includes dimensional verification, hardware operation testing, air and water tightness spot checks, and a thorough visual review. Products that fail any check are sent back for rework — quality is never sacrificed for speed.
Finished products are carefully wrapped and crated for ocean or air freight. We coordinate with trusted freight forwarders to ensure your order arrives safely at the destination port or directly at your project site.
Several variables can extend or shorten your production window. Knowing these upfront helps you plan more accurately:
A small residential order (10–20 units of standard casement windows) typically moves through faster than a 200-unit luxury villa project with mixed product types. However, our dual-facility setup means we can scale production efficiently even for large orders without proportionally extending the timeline.
Standard configurations in common colors ship fastest. Custom RAL color matching, special glass specifications (such as acoustic laminated or triple-glazed units), and bespoke hardware selections each add days to procurement and production. Our tilt and turn windows with passive-house-level thermal performance, for example, require additional assembly steps for the eight-layer sealing system.
Spring and early summer are peak construction seasons across many global markets. During these periods, order volume increases and lead times may extend by 5 to 10 days. Planning your order for fall or winter placement can help secure faster turnaround.
Standard profiles in 6060-T66 aluminum and common glass configurations are kept in stock for quick turnaround. Specialty items — such as extra-thick profiles for high-rise projects or imported hardware with limited stock — require additional procurement time.
We have structured our entire operation around reliable delivery. Here is what sets us apart:
