Answers Before You Send an RFQ
Direct answers based on the supplier’s public store information, with product-specific details confirmed during quotation.
Can OPPGATE manufacture from project drawings?
Yes. OPPGATE supports drawing-based, sample-based and bespoke project manufacturing. Share your opening schedule, CAD files, structural elevations and glass build-ups for an engineered quotation.
What information is needed for a window or door quotation?
Provide opening dimensions, quantity, operation type, thermal break profile specifications, glass build-up, surface finish, hardware requirements, destination and target schedule.
What is the minimum order quantity (MOQ)?
For standard listed project systems, MOQ starts from 1 set or 1–2 square meters. Bulk containerized supply receives dedicated tiered factory pricing.
How long does production and export delivery take?
Preparation is typically 15–20 days for sample or expedited orders. Full containerized orders take approximately 4–5 weeks depending on custom extrusions and glass specifications.
Which certifications and test reports are applicable?
Depending on the system specified, CE (European conformity), NFRC (thermal and SHGC ratings) and NOA (Miami-Dade hurricane impact) compliance documentation can be supplied.
