Questions
Before you ask for a proposal
Can you build outside China?
Yes, with a route confirmed for your country before you sign. Any licensed local contractor is named in the contract.
Do you need a complete design before you can quote?
No. A room list or floor area is enough for a first budget range. Drawings let us price the scope line by line.
Will the finished room meet GMP?
GMP approval belongs to your facility and your regulator. We design and build to the requirements you set and hand over test reports and documents for your review.
Can we buy only the panels and doors?
Yes. Choose supply only and your local team installs with our numbered panels, drawings and installation guide.
How much does a cleanroom cost?
It depends on class, area, air system and site work. Send a room list and we return a first budget range.
Who tests the room?
Tests normally cover airborne particles, airflow, pressure difference and filter leakage. The contract names who performs each test. The class of a finished room is confirmed by testing after commissioning.
