Founded in 2018, Shandong OptiDoors Technology Co., Ltd. serves as a bridge between advanced Chinese manufacturing and the sophisticated architectural demands of Spain. Our 8,200 m² facility is optimized for high-precision thermal break window production, essential for the diverse climate zones of Spain—from the Mediterranean coast to the plateau regions.
With 8 years of industry experience, we understand that Spanish building codes require rigorous compliance with CTE (Código Técnico de la Edificación). We ensure our aluminum windows meet these standards through comprehensive wind-load, salt-spray (essential for coastal areas), and impact testing.
As the construction industry shifts toward energy efficiency and sustainability, our 24 R&D experts are currently integrating "Smart Glass" technologies and high-performance polyamide thermal breaks to increase U-value performance. Our goal is to provide Spanish importers with windows that are not only durable but also future-proof for the EU’s Green Deal requirements.
