Frequently Asked Questions for Overseas Buyers
Essential information regarding customization, performance testing, and international shipping for Grandor aluminum sliding doors.
What structural and thermal standards do Grandor aluminum sliding doors comply with?
Grandor aluminum sliding doors are engineered and tested to comply with AS2047 (Australia), CE EN 14351-1 (Europe), NFRC energy ratings, and ASTM E283/E330/E547 standards. Test reports for specific profile series and glass build-ups are available upon request prior to order confirmation.
Can sliding door profile colors, dimensions, and hardware be customized?
Yes. Because profile extrusion, powder coating, and assembly are performed completely in-house, Grandor Door Industry Co., Ltd. customizes frame dimensions, colors (RAL palette, anodized, wood grain), glass specifications, and hardware configuration to your architectural drawings.
What is the production lead time and minimum order quantity (MOQ)?
Standard manufacturing lead time is 25 to 35 business days following shop drawing approval and deposit receipt. We support both full container load (FCL) wholesale shipments and project-based mixed door/window orders.
How does Grandor ensure sliding doors arrive undamaged during ocean freight?
All door frames and glass sashes are wrapped in protective polyethylene film, fitted with impact-resistant plastic corner guards, and packed into fully enclosed export-grade plywood crates designed for fork-lift handling and sea shipping.
