I. Core Hardware Costs

1. Drive Motor System (Most Critical Variable)

Function: Determines door operating speed, stability, and service life.

Motor Classification:

• Domestic Standard Motor (Asynchronous motor, speed ≤1.5m/s): Suitable for low-frequency use scenarios, such as warehouse back doors.

• Domestic Servo/High-Frequency Motor (Speed 1.5–2.5m/s, supports over 1,000 daily operations): Suitable for high-end scenarios like pharmaceutical and electronics industries.

Included Components: Motor body, control box, remote controller, limiter, and power module.

2. Door Frame (Cost Determined by Material)

Function: Supports the curtain and motor, ensuring structural stability.

Materials:

• Galvanized Steel Frame (Economic option, thickness 1.0mm): Suitable for dry indoor environments; prone to rust.

• 201 Stainless Steel Frame (Common option, thickness 1.2mm): Rust-resistant, suitable for workshops and logistics passages.

• 304 Stainless Steel Frame (Corrosion-resistant option, thickness 1.2mm): Suitable for food, pharmaceutical, or humid environments.

Included Components: Guide rails (sides + top), reel bracket, crossbeam, and fixing screws.

3. Zipper Curtain & Sealing System

Function: Provides sealing, insulation, and wind resistance during rapid opening/closing. The zipper structure is the core feature of "zipper doors" (curtain edges seal with guide rails via zippers, enhancing dust/insect proofing).

Curtain Material Thickness:

• Standard PVC Curtain (0.8mm thickness, regular type).

• Thickened PVC Curtain (1.2/1.5/2mm optional, tear-resistant and wear-resistant).

• Special-Function Curtain: Insulation/anti-static/UV-resistant.

Zipper System: Reinforced nylon/metal zipper tracks + sliders (additional cost; this is a unique feature of zipper doors, not found in standard rapid doors).

1. Q: What are the key components that determine a zipper door's cost structure?

   A: Primary value drivers include:

   • Motorization system (manual/automatic) • Fabric material grade and thickness • Safety sensor configuration • Frame construction material

2. Q: How does a zipper door's operational efficiency compare to traditional rapid doors?

   A: Performance advantages:

   ✓ 30-40% faster cycle times than conventional designs ✓ Lower energy consumption per operation ✓ Reduced air infiltration rates

3. Q: What maintenance requirements differentiate zipper doors?

   A: Unique upkeep aspects:

• Zipper track lubrication schedule

• Fabric tension adjustment frequency

• Sensor alignment checks

• Drive system inspections

4.Q: How do installation requirements affect project planning? 

A: Key considerations: 

❗ Structural support requirements

❗ Clearance space for zipper mechanism 

❗ Power supply specifications 

❗ Integration with building management systems
