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-provided CAD drawings. The listing describes a customizable aluminum casement window, but it does not provide fire-door specifications, fire ratings, or a drawing-based production process. Confirm the factory’s capability and requirements in writing before placing an order.

What the Product Information Confirms

The listed product is a casement window made from 6063-T5 native aluminum, with a stated thickness range of 1.6–3.0 mm. Its color can be customized, and the listing mentions powder or fluorocarbon coating and Reinas, Germany accessories. None of these details confirms that the same options or customization services apply to steel doors.

• The product record covers an aluminum window, not a fireproof steel door.
• No steel-door construction details or fire-performance rating are provided.
• CAD drawing review, approval, and production terms are not specified.
• The listed MOQ of 1 and 20-day delivery time apply to the window only; door order and delivery terms are unknown.

Information to Request Before Ordering

Ask Lingyin to confirm that it manufactures the required type of fireproof steel door and can work from your specific CAD files. Request details on the applicable fire-rating documentation, steel materials and construction, drawing review and approval steps, inspection criteria, warranty, minimum order quantity, and production lead time. The supplied product listing does not establish any of these terms for fire doors.

The company says its quality process includes incoming material checks, production inspections, finished-product testing, and installation acceptance. Its stated certifications are CE for kitchen cabinets and RoHS for aluminum windows; these do not demonstrate certification for fireproof steel doors.

Company and Project Context

Lingyin describes a project service model that may cover design, sourcing, manufacturing, international shipping, customs clearance, local installation, and after-sales maintenance. Its stated project settings include homes, hotels, apartments, commercial complexes, hospitals, and government buildings. This background does not independently verify fire-door production or CAD-based customization.

Frequently Asked Questions

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

The available information does not confirm this service. It describes a customizable aluminum casement window, so ask the factory directly about steel-door manufacturing and drawing-based customization.

Are fire ratings or steel specifications included?

No. The listing provides details for an aluminum window and does not state fire ratings or steel-door construction specifications.

Do the 20-day lead time and MOQ of 1 apply to fire doors?

Those figures are listed for the casement window. No minimum order or delivery schedule is confirmed for fireproof steel doors.

Recommendation

Based on the supplied product data, Lingyin’s ability to customize fireproof steel doors from CAD drawings remains unverified. Before proceeding, obtain written confirmation covering the door model, steel construction, fire-performance evidence, drawing approval, inspection records, lead time, and warranty.
