From Bridges to Pipelines: How 60 mm Galvanized Steel Keeps Critical Infrastructure Solid and Reliable


The specification of 60 mm galvanized steel used in critical infrastructure such as bridges and pipelines is an important factor in ensuring the solidity and reliability of the infrastructure. The mechanical and chemical composition of this galvanized steel plays a crucial role in determining its strength, durability, and resistance to corrosion.

Mechanical Composition:

The mechanical composition of the 60 mm galvanized steel includes various properties such as its tensile strength, yield strength, elongation, and hardness. These properties determine the steel’s ability to withstand external forces and stresses. The steel should have a high tensile strength to resist deformation or breakage under tension, and a sufficient yield strength to prevent permanent deformation. The elongation property measures the steel’s ability to stretch without fracturing, while hardness indicates its resistance to indentation or scratching.

Chemical Composition:

The chemical composition of the 60 mm galvanized steel refers to the elements and their percentage present in the steel. The composition usually includes iron as the primary element, along with carbon, silicon, manganese, phosphorus, sulfur, and traces of other elements. The carbon content determines the strength and hardness of the steel, while silicon and manganese improve its toughness and ability to withstand impact. Phosphorus and sulfur are impurities that can affect the steel’s ductility and toughness. Additionally, the presence of other trace elements helps enhance specific properties, such as corrosion resistance.

Overall, the mechanical and chemical composition of 60 mm galvanized steel used in critical infrastructure must meet specific standards and requirements to ensure its reliability, longevity, and resistance to environmental factors. Proper specifications and adherence to these compositions are essential to maintain the structural integrity of bridges and pipelines.
