In 2025, Yinlan Commercial customized and produced a "modular adjustable groove support system" for a large state-owned enterprise in Yunnan. This system is independently designed and developed by our company based on customer needs, with intellectual property rights. It is used for trench excavation and support in municipal engineering, water conservancy engineering, and other projects. Its main function is to prevent collapse during trench excavation due to various reasons, which may cause harm to construction personnel. The system is a "2+1" dual board mode with a board height of 3 meters, which can be assembled and adapted to grooves of different depths ranging from 1.5 to 3 meters; There are 2 sets of support poles with a total of 12 poles, and the adjustable inner width of the poles is 1-3 meters. The quality is excellent and the price is 40% lower than similar products in the market.

In 2026, the company reached a cross-border steel (galvanized steel, construction steel) trade cooperation agreement with a large enterprise group in Southeast Asia. The company is responsible for steel procurement and transportation within China, while the overseas company is responsible for domestic transportation and sales. Through cooperation, the company has opened up new international trade channels in Southeast Asia and South Asia.
