BS 3059 Steel Tube Chemical Properties

Our BS 3059 Steel Pipes are manufactured with a specific chemical composition to ensure their strength, durability, and resistance to corrosion. 

This composition includes a balanced mix of carbon, manganese, phosphorus, sulfur, and silicon. Each element plays a crucial role in enhancing the pipe’s properties and performance. 

For instance, carbon increases hardness and strength, while manganese enhances the pipe’s resistance to wear. 

We strictly adhere to the chemical requirements set by the BS 3059 standard, ensuring that our pipes deliver consistent performance and longevity.
