Including door type (garage door/industrial lift door/commercial door), installation scene (such as villa garage, factory door opening, shop entrance), size specification, material preference (steel/aluminum alloy/solid wood, etc.), special function (insulation/fire prevention/intelligent control, etc.) and project requirements. The customizer provides precise measurement of the opening dimensions (width, height, depth), wall structure (brick-concrete/steel structure/other), on-site environment (whether there are obstacles, power supply location, ground flatness), and records the installation conditions (such as whether there is reserved track space, strength of load-bearing beams, etc.) This includes the purpose of the door body (elevated garage/industrial workshop/warehouse logistics door/commercial door), installation location (indoor/outdoor), opening method (electric/manual), budget range and special requirements (such as insulation, wind resistance, fire resistance and anti-theft grades).

Based on the survey data and requirements, the customization party will provide a detailed design plan, including door structure drawings, dimension details, material specifications, hardware selection (tracks, motors, spring systems), and safety device configuration (such as emergency stop buttons and infrared anti-pinch sensors). Technical parameter confirmation: For industrial doors, the wind pressure resistance rating (based on the wind speed of the installation area), opening and closing speed, and motor power (matching the door weight) must be specifically defined; for garage doors, operating noise and insulation coefficient (such as PU foam filling for northern regions) must be confirmed.

Based on the technical confirmation plan, calculate costs for raw materials, custom processes, labor, etc., and provide a detailed quotation within 2 business days (including product specifications, unit prices, total costs, and payment terms). The customization party shall calculate costs (materials, processing, transportation, installation, after-sales service) based on the final plan and provide a detailed quotation. Upon confirming cooperation, a formal contract will be executed, specifying door parameters, delivery timeline, installation schedule, payment terms (typically a 50% deposit of the total amount), acceptance criteria, and warranty provisions.

Custom manufacturers initiate production according to technical drawings: This includes sheet metal cutting, bending and forming, surface treatment (such as acid washing and phosphating, high-temperature spraying), and component assembly (motors, tracks, balancing systems), ensuring the load-bearing structure of industrial doors and the smooth operation of garage doors meet standards. Critical quality inspections: These cover door panel flatness, weld strength (industrial doors), and anti-corrosion treatment of hardware components, preventing dimensional deviations during installation.

After the door assembly is completed, pre-installation testing is conducted at the factory: Simulating operational trajectories, inspecting whether motor operation is smooth, safety devices are responsive (e.g., obstacle-detection rebound function), and sealing performance (door gap clearance). A factory acceptance report is issued: Test data is recorded, and shipment is arranged only after confirming compliance with contractual technical requirements.

Upon completion of the finished product, the customer will conduct a video inspection or designate a third-party inspection agency. After confirmation of satisfaction, the final payment will be made, and shipment will be arranged. Simultaneously, video installation guides and after-sales contact information will be provided to ensure smooth subsequent installation.
