Boiler Quality Plates

BOILER STEEL PLATE :

When it comes to creating long-lasting pressure vessels and boilers, our Boiler Quality Plates (BQ Plates) stand at the top in terms of industry standards. Made with a view to withstanding inner pressures and high temperatures, these hot-rolled plates for steel become imperative in creating boilers, pressure vessels, gas turbines, heat exchangers, and storage tanks.

Our BQ plates have a 0.16% to 0.29% composition of carbon in a base of carbon steel, with an ideal combination of high strength and weldability. With such a composition, plates can resist high-pressure environments and can maintain integrity in structures.

To satisfy different industries Assembling, Shipping, and many industries, we offer them in a range of grades with different gauges including ASME SA516 Grade 70, and ASTM A516 Grade 70. Due to their very long life, and high durability, they become preferred materials for use in industries like petrochemicals, shipbuilding and oil and gas.

By choosing our Boiler Quality Plates, you're investing in materials that deliver high performance, reliability, and security in even the most extreme applications.
