Based in Houston, Houstan, Luke Steel is a reputable manufacturer and supplier of high-quality shipbuilding steel sheets and plates. With a wealth of industry knowledge, we are experts at providing high-performance steel products designed to satisfy the exacting requirements of the offshore and marine sectors. Modern technology is used to process our shipbuilding-grade steel, guaranteeing exceptional strength, resistance to corrosion, and long-term durability in challenging maritime environments. Luke Steel offers steel solutions that satisfy international classification standards, whether they are for offshore platforms, commercial ships, or military vessels. Quality, prompt delivery, and outstanding customer service are our top priorities both domestically and internationally.
Steel plates and sheets used in shipbuilding are made to be strong, ductile, and corrosion-resistant in the maritime environment. Depending on the grade, common grades like AH36, DH36, and EH36 offer tensile strengths between 400 MPa and 620 MPa and minimum yield strengths between 235 MPa and 355 MPa. Although the chemical composition varies slightly by grade, it usually contains trace elements like silicon, phosphorus, and sulfur, manganese, and low carbon content (up to 0.21%). These steels have outstanding impact resistance, weldability, and structural integrity—all essential qualities for offshore and marine applications.

For the construction and maintenance of many marine structures, shipbuilding steel sheets and plates are essential. They are extensively utilized in the construction of the bulkheads, decks, hulls, and superstructures of passenger ships, cargo ships, oil tankers, and naval ships. Because of their strong mechanical characteristics, they are perfect for marine terminals, platforms, and offshore oil rigs where corrosion prevention, strength, and fatigue resistance are crucial. They are also utilized in ship maintenance and conversion projects because of their weldability and resistance to saltwater conditions. These steels are safe, long-lasting, and perform well in harsh sea conditions because they meet international maritime standards.
Luke Steel is a leading manufacturer, supplier and exporter of high-quality Carbon Steel, Alloy Steel, Mild Steel and Galvanized Steel products. Our extensive product range includes Pipes, Tubes, Flanges, Pipe Fittings, Forged Fittings, Sheets and Plates, catering to various industries in Houstan, USA.
