Relying on the unique geographical advantage of Handan, the steel capital, we carefully select big-name raw material suppliers to ensure the supply scale and raw material quality.
Ensure that the raw materials of every product produced by the company are qualified raw materials to prevent unqualified raw materials from flowing into the next process.
Each semi-finished product can be put into storage or transferred to the next workshop only after passing the inspection, so as to implement quality control at every level.
Finished product inspection items include: product performance, accuracy, weight, safety and appearance.
Adopt advanced quality management system, trace every production process, and strictly control quality
If any quality problems occur, we will never evade them, but actively deal with them and promptly reissue new qualified products to customers.
Use advanced tools to measure wind speed, direction, and consistency to determine and the viability of wind energy.
Design a tailored wind energy system based on site data and energy needs. Handle all required permits,regulatory approvals
Install wind turbines, ensuring proper alignment for maximum efficiency. Connect the system to the power grid or a battery storage solution.
Offer upgrades or enhancements to improve system efficiency and longevity over time. Conduct regular maintenance and address any technical issues.
