Q
What materials are used for the door core and surface to ensure security?
Our security doors feature a multi-layer heavy-duty structure. The frame and skeleton are constructed from high-strength galvanized steel or structural aluminum. For the surface, we utilize solid hardwood veneers or precision-cast aluminum plates to ensure maximum impact resistance and security.
Q
Is the door suitable for coastal projects with high salt spray exposure?
Yes. For coastal regions, we recommend our aluminum-surface security doors with fluorocarbon (PVDF) coatings. This marine-grade finish provides superior resistance to salt spray corrosion and prevents the surface from bubbling or peeling over time.
Q
Do these security doors provide thermal insulation?
Yes, specifically our thermal-break models. By incorporating polyamide (PA66) thermal strips within the frame and leaf, we effectively break the bridge of heat transfer, keeping the interior temperature stable and reducing energy costs in extreme climates.
Q
What customization options are available for oversized entryways?
For luxury villas and grand entrances, we specialize in oversized pivot doors and "Door with Sidelight" configurations. We can manufacture custom security doors up to 5000mm in height while maintaining full security and structural stability.
Q
What is the material structure of the door?
Our doors are engineered with a multi-layer composite structure:
1. Outer Layer: Weatherproof cast aluminum panels or premium solid wood (such as Mahogany/Oak) treated with UV-resistant coatings.
2. Core Layer: A reinforced steel structural skeleton filled with high-density aviation-grade aluminum honeycomb, polyurethane foam, or fireproof rock wool, providing outstanding anti-theft, acoustic, and thermal performance.
Q
How can I ensure the product quality matches my order before it leaves the factory?
We implement a 100% pre-shipment inspection protocol. Once production is complete, our QC team verifies the dimensions, hardware alignment, and surface finish against the signed shop drawings. We will send you a comprehensive inspection report containing high-definition photos and operation videos (showing opening/closing and locking). We also welcome third-party inspections (such as SGS or BV) at our facility.
