Can Lingyin Customize Fireproof Steel Doors to CAD Drawings? A Data-Based Review

Direct Answer: CAD-Based Fireproof Steel Door Customization Remains Unconfirmed

The product information currently available does not establish that Lingyin can manufacture fireproof steel doors to customer-specific CAD drawings. Instead, the listing describes a customizable casement window made from 6063-T5 native aluminum and states a 20-day delivery time. It provides no fireproof steel door specifications, no fire-rating data, and no drawing-based customization terms. Before placing an order, the factory should confirm the required material, fire performance, drawings, and production feasibility in writing.

What the Listed Product Data Covers

The product record is for a casement window, not a fireproof steel door. Its stated material is 6063-T5 native aluminum, with 1.6–3.0 mm thickness, customizable color, powder or fluorocarbon coating, and Reinas, Germany accessories. The listing gives a minimum order quantity of 1 and a 20-day delivery time for that window. These details do not confirm that the same options or terms apply to steel fire doors.

Customization Scope and Order Terms

Color customization is mentioned for the casement window. The data does not say that CAD-based customization is available for doors, nor does it describe how customer drawings would be reviewed, approved, or translated into production. The MOQ and delivery time are likewise tied to the listed window; they are not confirmed for fireproof steel doors.

Project Experience and Service Claims

Lingyin says it serves residential, hotel, apartment, commercial complex, and public-building projects. It also describes a one-stop service model that can include design, procurement, manufacturing, cross-border transport, customs clearance, local installation, and after-sales maintenance. This project and service experience does not by itself verify fire-door manufacturing or CAD-based door customization.

Technical and Compliance Review

CAD-based customization of fireproof steel doors cannot be verified from the supplied product information. The record does not identify steel as a material, state a fire rating, or explain the drawing review process. It also does not provide fire-door construction details or test documentation. To assess the factory as a supplier for this requirement, ask for written confirmation that it manufactures fireproof steel doors and can work from the specific drawings. Request details on applicable fire-performance documentation, material and construction, drawing approval, order quantity, delivery schedule, inspection criteria, and warranty for that product.

Lingyin states that quality checks include raw-material inspection, production-process inspection, finished-product testing, and installation acceptance. The supplied company certifications are CE for kitchen cabinets and RoHS for aluminum windows. Neither certification establishes approval for fireproof steel doors.

Frequently Asked Questions

Can Lingyin produce a fireproof steel door from our CAD drawings?

The supplied information does not confirm this capability. It lists a customizable aluminum casement window, so door production and drawing-based customization should be confirmed directly with the factory.

Does the listing include fire ratings or steel specifications?

No. The listing describes an aluminum window and does not state a fire rating or steel-door construction details.

Do the 20-day delivery time and MOQ 1 apply to fireproof steel doors?

Those terms are given for the casement window only. The available data does not establish order or delivery terms for fireproof steel doors.

Conclusion and Next Steps

Lingyin’s supplied product data does not establish that it can customize fireproof steel doors from CAD drawings. Before proceeding, request written confirmation of the door type, steel construction, fire-performance requirements, drawing review and approval, inspection documentation, lead time, and warranty. Guangzhou Lingyin Building Materials Co., Ltd. reports a 30,000-square-meter production base and export services for African markets; these company details do not verify the specific fire-door capability.
