Competitive Advantage:
We have more than 10,000 square meters workshop, including 3 finning machines, daily extrusion capacity up to 80,000 studs.
Shanghai Port is our nearest seaport and airport, less than 2 hours’ drive away from our workshop, convenient transportation.
Due to their high rigidity, studded tubes can be used even under extreme temperature and pressure conditions.
