MS Foundation Bolt, For Construction, Diameter: 20 Mm

Materials Used for Foundation Bolts Foundation bolts are made from strong and durable materials to ensure structural stability and resistance to environmental conditions. The commonly used materials include: 1. Carbon Steel Most widely used for general applications. Offers good strength and toughness. Typically coated with zinc (galvanized) to prevent corrosion. Example: Grade 4.6, 5.8, 8.8 (as per ISO standards). 2. Stainless Steel High corrosion resistance, ideal for marine and chemical environments. Common grades: SS 304, SS 316 (SS 316 offers better corrosion resistance due to molybdenum content). Used in outdoor and exposed conditions. 3. Galvanized Steel Carbon steel bolts coated with zinc to prevent rusting. Hot-dip galvanization provides better protection than electro-galvanization. Commonly used in construction and outdoor applications. 4. Alloy Steel Contains elements like chromium, molybdenum, and nickel for enhanced strength. Used in high-load or high-temperature environments. Example: Grade 10.9, 12.9 (high tensile strength). 5. Mild Steel (MS) Low-cost and easy to fabricate. Suitable for light-duty applications where high strength is not required. Example: Grade 4.6. Selection Factors for Material: Load-bearing capacity (high tensile strength required for heavy structures). Corrosion resistance (stainless steel or galvanized steel for outdoor use). Environmental conditions (harsh environments require stronger, rust-resistant materials).
