Q: How does this door compare to traditional wooden or fiberglass entry doors?

A: Steel doors offer 3–5x the impact resistance of wooden doors, do not warp or rot like wood, and provide significantly better security than fiberglass alternatives. Our galvanized steel construction with anti-rust treatment ensures decades of maintenance-free service. The door is CE EN 14351-1 certified for mechanical strength, weather tightness, and thermal performance — standards that most wooden doors cannot meet. With OEM/ODM flexibility, you get the strength of steel without compromising on design or customization.

Q: What is the minimum order quantity (MOQ) and what certifications do you provide?

A: Our standard MOQ for OEM/ODM orders is 50 units per design/color, though we can discuss smaller trial orders. We provide full certification documentation including CE EN 14351-1 Declaration of Performance (DoP), RoHS compliance certificates, and ISO 9001:2015 quality management certification. Pre-shipment inspection reports are available upon request. Our typical production lead time is 25–35 days, with sea freight shipping options to major ports worldwide.
