Types of Steel Shapes Rolled Steel Shapes and built-up shapes are most famous different steel shapes available. The Rolled steel shapes standardized hot-rolled shapes with cross-sectional dimensional and properties specified. Built up shapes standardized structural shapes can not be used where the load to be subjected exceeds the capacity of the sections. Built up steel shapes could be made from plate stock.
Standard Steel Shapes Types
Standard hot rolled shapes are most commonly used for building construction. Builtup shapes are commonly used in bridge construction. Welded plate girders also used in building construction as transfer girders to support multistory columns above an atrium area or an auditorium or roadway large column-free area. Wide flanged W-Shapes and M-Shapes are commonly used as beams or columns in steel structures. Wide flanged steel used as top and bottom chord members of trusses and as diagonal braces in braced frames.
Uses of S-Shapes, properties. S-Shapes also known as American standards beams. These are similar to I-Shapes except that the inside flange surfaces are sloped. The inside face of the flange usually has slope of 2;12 with the flange thickness varying from a smaller value at the flange tips to a larger flange thickness closet to the web of the beam.
HP Shapes are similar to w-shapes and are commonly used as H-Piles in bearing pile foundations.These H-Piles which can be as long as 100ft. or more support the superstructure loads. HP Shapes have thicker flanges and webs compared to w-sections and the nominal depth of these sections is usually approximately equal to the flange width, with the flange and web thickness approximately equal.
C Shapes and MC-Shapes:
C-Shaped members with inside adjacent faces of channel flanges tapered from minimum thickness at the flange tip to a maximum thickness at the channel web. MC Shapes are commonly used as beams to support light loads, such as in catwalks and as stair stringers, and there are also used to frame the edges of roof openings.
Steel types, built-up sections include welded plate girders and other sections built up from plates and standard rolled sections. Plane and flanged cruciform sections. Plate girders are used to support heavy loads where the listed standard rolled steel sections are inadequate to support the loads.
Built-up sections can also be used as lintels and as reinforcement for existing beams and columns. W-Shapes and M-Shapes with cap channels that are used to increase the bending capacity of W and S-Shapes.
