Experience of export 1.Have more experience of exporting and had cooperated with more than 20 countries and areas, including UK, Poland, Israel, Tunisia, Russia, Canada, Chile, Peru, Australia, UAE, India, Malaysia, Indonesia,Vietnam, Laos, Thailand, Korea, HK and Taipei etc. EQUIPMENT 2.Large size vertical machine；Large size boring mill；Automatic Rolling machine；Automatic flame cutting machine；Automatic welding machine TEST EQUIPENT Test equipment for all size to make sure the product quality.

1.Corrosion resistance: acid and alkali resistance and most of the corrosive chemicals and sewage, seawater; 2. Good sealing performance: the rubber is used to seal metal, and the water stop rubber ring is hollow structure with good sealing performance; 3. Small torque: for the light weight of the door plate, the friction resistance between the door plate and the guide rail is small, so the operating torque of the hand wheel is not greater than 100N； 4. Independent structure: reliable temperature and rigidity welding structure, high-performance seals ensure the effective opening and closing of the gate, independent seal and wedge design make the gate more reliable, and can be subject to large reverse water level; 5. Long service life: because the door plate and the guide rail only contact with the last small section of sealing, the sealing wear is very small; The service life of stainless steel gate is more than 10 years, and that of carbon steel gate is more than 5 years; 6. Convenient maintenance: the wedge block can be adjusted.
