Steel Bridges are preferred over their concrete made counterparts for lower construction cost and less maintenance charge. Moreover, steel fabricated bridge has less weight than the concrete made variant. due to their excellent strength to weight ratio. Being long lasting, steel made bridges reduce replacement cost. Bridge structure made of steel can adapt to various climactic conditions that prove to be advantageous for their longevity.  Moreover, Steel Bridges remain unaffected even during earthquake. Being recyclable, these types of bridge structures reduce environmental pollution in case these are collapsed.  Standard of these steel made structures has been verified as per their strength, coverage area, construction and maintenance cost, safety features and load bearing capacity.
