The Guizhou Hua Jiang Gorge Bridge, acclaimed as the tallest and widest bridge in the world, is set to open soon, slashing travel time from 2 hours to just 2 minutes. As a key transportation hub and ecological barrier in southwestern China, Guizhou's infrastructure needs—particularly in highways and water conservancy—are rapidly growing. In response, local building material companies are pushing for technological upgrades and smart transformations to boost production efficiency and promote sustainable practices. Recently, Qunfeng Machinery is on the verge of completing the commissioning of a fully automated production line tailored for clients in Guizhou, a project poised to bring robust and environmentally-friendly momentum to regional infrastructure.
