Frequently Asked Questions About Steel Front Doors
Professional answers to common technical, quality, and shipping questions asked by international buyers.
Yes. Our custom steel front doors feature high-density polyurethane insulation cores and dual perimeter EPDM gaskets that closing tightly, blocking external noise effectively and improving acoustic comfort.
No. The thermal-break frame structure and polyurethane insulated foam core stop heat transfer between external metal sheets and indoor environments, keeping indoor spaces comfortable in warm climates.
Steel front doors offer the highest structural forced-entry resistance. Unlike solid wood, steel doors do not warp, crack, or rot when exposed to humidity and extreme weather. Compared to fiberglass, heavy-gauge steel provides enhanced impact durability and long-term security.
Our steel entry doors can be integrated with 3-point, 5-point, or 7-point automatic mortise locking systems, anti-drill key cylinders, anti-pry hinge pins, and smart biometric keyless handles for maximum anti-theft protection.
Every steel front door by Foshan Derka Architectural Doors & Windows Co., Ltd. is made to measure. You can select exact frame dimensions, RAL powder coat colors, heat-transfer wood grain finishes, hardware styles, and tempered low-E frosted or clear glazing.
Once CAD shop drawings are confirmed, standard manufacturing takes approximately 15 to 25 days. Finished units are secured in export-grade reinforced wooden crates labeled by opening number for safe international transit.
