Our company started as a civil air defense engineering brand 4 years ago. We make products with care and have no quality feedback within 4 years. We have won wide recognition from engineering companies in the industry and have expanded rapidly: we have our own factory and add 300,000 to 400,000 pieces of equipment every year. All materials are purchased from manufacturers. Due to the impact of the general environment and the sluggish real estate industry, it is urgent to expand the product chain and customers. Therefore, we invest in new equipment, expand new production capacity, and develop new processes. We will use the approach and attitude of being a "civil air defense engineering brand" , try our best to solve the "face engineering" and "lining engineering" of products, bring beautiful products to customers with affordable value, and once again win the recognition of all customers.
