Unpowered ventilators, also known as roof ventilators, natural ventilators, power-free ventilators, and turbine ventilators, are ventilation equipment installed on both sides of the roof ridge of industrial plants. They can replenish sufficient outdoor fresh air 24 hours a day without electricity, promote air circulation and convection in the plant, improve the working environment, and ensure the health of employees.

Bolt balls are mostly used in grid structures. The main structural feature is that multiple holes with internal threads are opened on a ball to connect multiple rods at one point. Bolt balls are mainly used in the fields of oil pipe-free downhole oil production equipment, casing explosion expanders, oil pipe diameter gauges, etc. They are also used in grid steel structures to connect rods to rods.

Z shape steel is a common cold-bent thin-walled steel with a thickness of 1.6-3.0mm and a section height of 120-350mm. The processed material is hot-rolled (painted) and galvanized. The processing standard is in accordance with GB50018-2002. Z shape steel is usually used in large steel structure workshops. The processing length and holes are produced according to the processing requirements.
