Marzouk Steel is a trusted manufacturer and supplier located in Tunis, Tunisia, specializing in high-quality hot-dipped galvanized bolts for both construction and industrial uses. These bolts are crafted from strong steel and undergo a meticulous hot-dip galvanizing process, which gives them exceptional corrosion resistance and a long lifespan. Marzouk Steel is committed to maintaining strict quality control, ensuring precise threading, and adhering to international standards. The company caters to the infrastructure, fabrication, and engineering sectors, providing reliable fastening solutions that deliver consistent performance, timely delivery, and a customer-focused approach, even in demanding environments.
Hot Dipped Galvanized Bolts are zinc-coated fasteners through the hot-dip galvanization process to improve their resistance to corrosion. These bolts are essentially constructed of Carbon Steel (98-99%), coated with Zinc Coating (5-10%), giving a protective, long-lasting layer. The method includes submerging the bolts in molten zinc at about 450°C, so a solid, even coating is formed. This coating greatly prolongs the life of the bolt by protecting it from rust and damage from the environment, so it is suitable for use outside.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
Hot-dipped galvanized bolts are made from carbon or alloy steel and are coated by dipping the finished bolts into molten zinc. This method creates a thick, resilient zinc layer that shields the steel from corrosion, rust, and environmental wear. Mechanically, these bolts boast high tensile strength, shear resistance, and impressive load-bearing capacity, all while enjoying enhanced surface protection. The zinc coating also offers sacrificial protection, ensuring long-lasting durability, even in harsh outdoor or marine settings where moisture and chemicals are prevalent.
These hot-dipped galvanized bolts are commonly found in construction, infrastructure, and industrial projects where corrosion resistance is crucial. Typical uses include steel structures, bridges, transmission towers, guardrails, poles, outdoor equipment, and coastal installations. They are also frequently utilized in renewable energy projects, heavy machinery, and agricultural structures. Their durability and reliability make them perfect for long-term fastening in exposed environments, ensuring structural safety, minimizing maintenance, and providing cost-effectiveness over extended service periods.
