Welcome to Henan Jinhuaiyu Machinery & Equipment Co., Ltd. – your reliable partner in precast concrete construction solutions. Our Easy-installation Grouting Protective Cover is engineered to shield anchor assemblies during the critical duct-grouting process of precast box girders. With a dedicated team of 51–100 skilled professionals and a modern factory spanning 1,000–3,000 square meters, we deliver precision products that enhance on-site efficiency and structural integrity. This cover is designed to simplify your workflow while ensuring maximum protection against grout spillage and anchor contamination.
The grouting protective cover is a must-have accessory for any bridge or viaduct construction project using precast box girders.
