Luke Steel, located in Houston, Houstan, has built a solid reputation as a top-notch manufacturer and supplier of premium E690TM Sheets and Plates. They cater to clients in the shipbuilding, offshore, and heavy engineering sectors. With a strong commitment to providing high-strength steel solutions, Luke Steel’s E690TM plates are celebrated for their outstanding weldability, toughness, and durability, making them perfect for demanding marine and structural applications. Thanks to their state-of-the-art processing facilities, rigorous quality assurance, and a focus on customer satisfaction, Luke Steel guarantees that every E690TM sheet and plate meets international standards, supporting crucial projects that require exceptional performance in tough conditions.
E690TM Sheets and Plates are high-strength, thermomechanically rolled structural steels that incorporate micro-alloying elements like niobium, vanadium, and titanium. These elements help refine the grain structure and boost strength. Typically, they offer a yield strength of around 690 MPa and a tensile strength ranging from 770 to 940 MPa, along with impressive impact toughness, particularly in low temperatures. These plates strike a balance between high strength and good weldability and formability, making them ideal for large, load-bearing structures in challenging environments while ensuring structural integrity and resistance to fatigue.

We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
In the shipbuilding industry, E690TM Sheets and Plates are commonly used to fabricate hulls, decks, and offshore platforms that require high strength-to-weight ratios and the ability to withstand harsh marine conditions. They’re also essential in heavy structural engineering for cranes, bridges, and lifting equipment, where superior load-bearing capacity is a must. Offshore oil and gas structures, subsea components, and wind tower constructions frequently rely on E690TM plates for their toughness and weldability. Their durability and high yield strength help reduce structural weight while ensuring safety and performance, making them perfect for projects that face dynamic loads and severe weather conditions.
