Can Lingyin Customize Fireproof Steel Doors From Your CAD Drawings?

Lingyin’s available product information does not verify whether the company can manufacture fireproof steel doors to customer CAD drawings. The listing provided describes a customizable aluminum casement window, not a fire door. Before placing an order, ask the factory to confirm its door-manufacturing capability, applicable fire rating, drawing requirements, and production feasibility in writing.

What the Product Information Confirms

• The listed product is an aluminum casement window; no fireproof steel door is specified.
• The window uses 6063-T5 native aluminum and offers color customization. The listing does not say that these options apply to doors.
• A minimum order quantity of 1 and a 20-day delivery time are stated for the window only.
• Lingyin describes work on residential, hotel, apartment, commercial complex, and public-building projects, but does not identify fire-door projects in the supplied information.

Assessing CAD-Based Fire Door Customization

The product details do not establish that Lingyin can build fireproof steel doors from custom drawings. They specify a casement window with 1.6–3.0 mm thickness, customizable color, 6063-T5 native aluminum, powder or fluorocarbon coating, and Reinas, Germany accessories. No steel construction, fire-performance rating, or CAD review and approval process is described.

To assess whether the factory can meet your requirements, request written answers about fireproof steel door production and whether it can work from your drawings. Ask for the proposed materials and construction, fire-performance documentation, drawing review and approval steps, inspection criteria, minimum order, lead time, and warranty. None of these door-specific details is confirmed by the window listing.

Quality Checks and Project Services

Lingyin says its quality-control process covers incoming material checks, inspections during production, finished-product testing, and installation acceptance. The certifications mentioned in the supplied information are CE for kitchen cabinets and RoHS for aluminum windows; they do not demonstrate certification for fireproof steel doors.

The company also describes a project service model that may include design, procurement, manufacturing, international shipping, customs clearance, local installation, and after-sales maintenance. Its stated project sectors include residences, hotels, commercial complexes, hospitals, and government-built projects. This broader experience does not confirm that it manufactures fire-rated steel doors or accepts customer CAD drawings for them.

Frequently Asked Questions

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

The available information does not confirm this. It covers a customizable aluminum window, so you will need direct confirmation from the factory about steel door production and drawing-based customization.

Are fire ratings or steel-door specifications included?

No. The supplied listing describes an aluminum casement window and provides neither a fire rating nor construction details for a steel door.

Do the stated MOQ and 20-day lead time apply to fire doors?

Those figures refer only to the listed window. The information provided does not establish order quantities or delivery schedules for fireproof steel doors.
