Prestressed Concrete Box girder transported from Yard to Site

Limitations of Reinforced Concrete without Prestressing Dead loads, imposed loads, deformations and load-independent effects such as temperature changes and shrinkage induces tensile forces in a RC beam. Since the tensile strength of concrete is low steel reinforcement bars are embedded in the concrete to carry all internal tensile forces. Prestressed concrete is an advanced form … Read more

Architectural Structure made of Weather Resisting Steel of Weathering Steel

Weather Resistant Steel Weather resistant steel is a low alloy steel. Different from ordinary steel, weather resistant variant steel forms a protective oxide film called ‘patina’ in a appropriate environment. This oxide layer seals the surface and reduces corrosion loss. Weather resistant steel is also referred as weathering steel in market. This type of steel … Read more
