Frequently Asked Questions (FAQ)

Expert answers regarding our CE certified aluminum casement windows, manufacturing capabilities, international shipping, and customization services.

What certifications do your aluminum casement windows and doors hold?

Our products are manufactured under strict ISO9001 quality management systems. Many of our window and door lines are NFRC certified, Energy Star compliant, Miami-Dade NOA approved, and bear CE markings, making them fully compliant with European, North American, and Middle Eastern building regulations.

What is the typical production lead time for bulk wholesale orders?

Thanks to our 8,200 m² advanced manufacturing facility equipped with fully automatic laser cutting and multi-axis drilling machines, standard custom orders are typically produced and ready for shipment within 25 to 35 days, depending on project scale and surface finish requirements.

Can you provide custom RAL color matching and specialized thermal break options?

Yes. Our R&D team of 24 experts specializes in bespoke architectural solutions. We offer full RAL color powder coating, wood-grain finishes, multi-point security locking systems, and high-performance thermal break cavities designed to maximize energy efficiency in extreme climates.

How do you ensure safe international shipping for fragile glass and aluminum assemblies?

We employ rigorous export packaging protocols, utilizing reinforced wooden crates, protective edge guards, and moisture-barrier interleaving. Our 16 dedicated QA officers oversee every item prior to crating to guarantee zero transit damage upon arrival at global destination ports.
