3. Pricing Transparency Confirmation: Insist on pricing calculated per square meter, and request a detailed quote including material costs, processing fees, installation fees, and after-sales service charges. Avoid products with vague pricing structures that may include hidden fees.

4. After-sales Service Evaluation: Choose manufacturers with dedicated after-sales contacts and a nationwide service network. Confirm the warranty period for core components and the response time for maintenance requests.

5. Customization Capability Check: For non-standard door opening sizes, verify whether the manufacturer supports flexible customization, including door size adjustment, surface pattern design, and lock system configuration.
