Packing of Soundproof door:

Standard Packaging

Each soundproof door is wrapped with protective PE film and secured with foam corner guards for four corners. Door frames, door leaves and loose hardware accessories are packed separately in reinforced export cartons. All finished products are fixed with wooden frames and placed on fumigated wooden pallets, secured with steel straps and stretch film for international shipment.

Other terms may be available upon request. Shipping costs are calculated based on cargo volume, gross weight, destination and selected transportation method.

Lead Time

Samples: 10 working days

Standard orders: 15–25 working days

Customized orders: 25–40 working days

Q1: How long does sample preparation take?

A: Soundproof door sample production takes 10 working days according to standard size configuration.

Q2: What information do you need for a custom quotation?

A: We need door size, opening method, required sound insulation decibel level, color and order quantity to provide accurate quotation.

Q3: What is the MOQ and production lead time?

A: MOQ is 10piece. Standard orders take 15–25 working days, customized orders take 25–40 working days.

Q4 What is the difference between soundproof door and ordinary door?

A: Ordinary doors only have simple door panel structure with serious gap sound leakage. Our soundproof door adopts multi-layer sound absorption barrier and full sealing structure, which can effectively reduce noise transmission and achieve professional noise reduction effect.

Q5 Can this door be used for outdoor factory environments?

A: Yes. The galvanized steel surface is anti-rust and weather-resistant, suitable for outdoor workshops, equipment rooms and long-term open-air building entrances.

Q6 Will the soundproof effect decrease after long-term use?

A: The internal sound-absorbing material is stable and non-deformable, and the rubber sealing strip has aging resistance. The overall sound insulation performance remains stable after long-term use.
