Durable chromium-based stainless steel rebar significantly improves the durability of concrete structures and greatly reduces repair and maintenance costs. By using it in the most corrosion-prone areas of structures, which are difficult and costly to repair, it demonstrates high cost-effectiveness. It expands and alleviates crack width restrictions, reduces concrete cover thickness, and allows for lightweight cross-sections. Additionally, since it does not require surface treatment, it can be processed and handled similarly to ordinary rebar. 【We are currently offering free samples!】 Please feel free to consult with us first! Our specialized staff will respond carefully.
