Production-control records
We run a full factory production control system and can supply the records behind it, so the units you receive match the sample your test report was issued against.
OEM / Contract Manufacturing — Yantai, China · Est. 1999
Your drawings.
Your brand.
Our line.
System windows, aluminum-clad wood windows and sunrooms built to your specification — for importers, window fabricators and private-label brands.
We build to your drawings.
Your design, your specification and your compliance documents stay yours. Drawing review, sample approval and a pilot batch come before any volume production — and the manufacturing evidence behind the product is available to you.
Advance notice of any change
Material, profile, hardware and process changes on your order are notified in writing, and made only with your approval.
Batch traceability
Every order is traceable — order to profile, glass and hardware batch numbers to inspection records — and the records can travel with the shipment.
Audits and sampling
Your engineers or your nominated inspector are welcome at the Yantai plant at any stage, and we build sample units for testing by the body you nominate.
NDA and dedicated tooling
We sign your non-disclosure agreement before drawings are shared, and tooling made for your profile runs your orders only.
