Top flange width Minimum width 350 mm Minimum width to facilitate shear studs,splices and precast formwork. The designer of a steel bridge has to determine the method of construction as this must be taken into account in the design of the steelwork. Weldable reinforcing steel.Bar,coil and decoiled product.Specification.Bridges Types,Span and Loads Civil EngineeringA brief description of some types of steel bridges is given below (i) Beam and Slab Bridge These are convenient where the span of the beam exceeds 5 in.For small spans I-section beams may be used.For spans more than 8 m,built-up I-sections or plate girders are used.CR Coils - CR Sheets,Cold Rolled Coils,Cold Rolled Width Tolerance Coil Weight Coil ID Coil OD Length Tolerance (For Sheets) Camber Tolerance 1.5 mm 6 mm 50 mm 1500 mm 500 mm to 4000 mm Mill Edge/ Slit Edge +/- 0.05 mm As per Specification Depends on Size Specification 600 mm up to 1500 mm 0 mm/+3 mm 1.50 mm Max.per 1000 mm
