Q235 Steel Pipe & Tube

Amardeep is a renowned manufacturer, supplier, and distributor of Q235 galvanized steel pipes, based in Mumbai, India. We maintain a ready stock of these Q235 hot-dip GI pipes, offering them at highly competitive prices. Our range includes various types, sizes, wall thicknesses, diameters, shapes, and custom specifications. These GI Q235 Pipes are crafted using top-quality raw materials and state-of-the-art technology, adhering to globally recognized quality standards.

Q235 stands as a plain carbon structural steel with a yield strength of approximately 235MPa, a value that may vary with material thickness. The 'Q' symbolizes the material's yield limit, while '235' denotes the approximate yield strength in megapascals (MPa). Notably, galvanized steel Q235 pipes do not necessitate specific process treatments like preheating or post-welding heat treatment during welding. They offer practical efficiency, affordability, and high-cost performance.

Q235 Steel Pipes exhibit robustness, weldability, and excellent plasticity. They maintain their strength even when subjected to bending in cold temperatures. These galvanized steel Q235 pipes find extensive use in sectors such as engineering and construction. Applications span across factory buildings, steel bars, towers, boilers, bridges, containers, automobiles, and various welded structures that benefit from the structural properties of Q235 steel. Additionally, Q235 Structural Steel Pipes can serve as mechanical components.

Our commitment to quality ensures that all our GI Q235 Pipes undergo rigorous quality checks, guaranteeing their suitability for various environmental conditions. We also provide a range of test certificates and offer third-party inspections to further validate the quality of our pipes.
