Carbon Crystal Interior Door Multi-Layer Paint-Free Apartment Hotel Custom Size Contractor Project

Wall thickness, opening size, opening direction, frame type, and casing requirement should be confirmed before production. Many door problems come from incomplete site information rather than the door leaf itself. For project orders, we recommend confirming these details in writing before mass production.

Lock, hinge, and handle are optional accessories unless they are clearly included in the confirmed order scope. Buyers should confirm whether they need only a door leaf, a door leaf with frame and casing, or a complete door set with hardware. This avoids confusion during installation.

Hardware compatibility should be checked before ordering. If the buyer plans to use local hardware, the hinge size, lock body, handle position, and cut-out requirement should be shared in advance. Without this confirmation, additional site modification may be needed.

Buyers should provide the original model number, finish, confirmed size, and order record. For repeat orders, we first check the previous product information so that the replacement or additional door matches the earlier supply as closely as possible.

The most common issues are wrong wall thickness, unclear opening direction, unconfirmed hardware scope, mixed casing requirements, and color approval based only on-screen images. These details should be confirmed before production, especially for orders involving hotels, apartments, and residential projects.
