Structural Steel Shapes
Structural Steel ShapesA wide variety of shape options further allow structural steel products to support building and design. The shape is integral for the correct distribution of load weights and pressures, with the proper selection ensuring that a building is durable and safe. Different shapes of structural steel each have unique mechanical and chemical properties that make them appropriate for different applications. These shapes include:
Angles. These perpendicular, L-shaped cross-sections, either with equal or unequal legs, are commonly found in corners of structures and other places to supplement main pillars and beams.
Tubing. Hollow tubing made from hot-rolled steel coils and sold in round, square, and rectangular shapes is easily fabricated and welded according to need. It's a lightweight structural alternative to solid structural steel products.
I-beams. These beams are one of the most common structural steel products for both beams and columns. The two parallel elements of the "I" or "H" cross-section are known as flanges, and the connecting element is known as the web.
Wide flange beams. With a much longer web than in I-beams, the flanges of a wide flange beam are almost perpendicular to the web.
Channels. Structural channels are hot-rolled into a C-shape, which, like I-beams, have a wider angle of attachment between the flanges and the web. They provide structural support in addition to a main load-bearing beam, most commonly for bracing or framing.
Plates. Carbon-steel plates can withstand massive amounts of weight and pressure, making them perfect for ocean vessels. These are heavy-duty, wide surface areas of solid, continuous structural steel meant to span large areas.
Bars. Short for merchant bars, these are hot-rolled and cold-finished carbon types of bars with different properties, dimensions, and shape sub-categories, such as round, square, and flat cross-sections.
Common types of steel structures
There are many different types of steel structures, each designed to meet specific requirements. Here are some of the most common types of steel structures:
Steel frame structures
These are the most common type of steel structures and are used in a wide range of buildings, from high-rise offices to residential homes. The steel frame structure consists of vertical steel columns, horizontal steel beams, and steel connections that hold the members together. The beams and columns are connected by welding or bolting, creating a rigid and stable structure.
Steel truss structures
Steel truss structures are a type of construction method that uses a series of interconnected triangles to distribute weight evenly across the structure. Steel truss structures are commonly used for roofs and bridges, but can also be used for other applications where long spans are required.
Steel arch structures
These structures are used for bridges and buildings where a long span is required. The steel arch structure consists of a curved steel arch that supports the weight of the structure. The arch is made up of a series of connected steel members that form a curved shape.
Steel cable structures
Steel cable structures are a type of construction method that uses steel cables to support the weight of the structure, creating a suspension system. They are commonly used for suspension bridges and roofs. The steel cable structure consists of steel cables that are anchored to towers or columns at either end of the structure. The cables are then stretched taut across the span of the structure, creating a suspension system that supports the weight of the structure. The cables are anchored to the ground or to concrete blocks to provide additional stability.
Steel space frame structures
Steel space frame structures are a type of construction method that uses a three-dimensional framework of steel tubes to support the weight of the structure. Steel space frame structures are commonly used for large buildings such as airports and sports arenas. The steel space frame structure consists of a series of steel tubes that are welded together to create a three-dimensional framework. The framework is then covered with roofing and cladding materials to create the final structure.
Light gauge steel structures
Light gauge steel structures use lightweight steel frames to support the weight of the structure and are commonly used for residential and small commercial buildings. The light gauge steel structure consists of steel frames made of thin sheet steel that are cold-formed into C-shaped or Z-shaped sections. The sections are then assembled into a frame using screws or bolts.
Pre-engineered steel structures
Pre-engineered steel structures are a type of construction method that uses standardized components that are prefabricated off-site and assembled on-site. Pre-engineered steel structures are commonly used for industrial buildings such as factories, warehouses, and distribution centers. The pre-engineered steel structure consists of standardized components such as steel columns, beams, purlins, and girts that are designed to fit together easily.
What are the types of structural steel that go into structural steel buildings
A36
A36 is a widely preferred and versatile low-carbon low-cost steel known for its yield strength (36,000 psi) and excellent machinability. A36 can elongate to about 20% of its original length, and is commonly used for columns, beams, decking and finish elements. While it has decent ductility, A36 steel is not used for reinforcement.
A572
A572 is a high-strength low-alloy steel (HSLA) steel plate. This weldable, low-alloy structural steel has similar yield and tensile strength to A36 steel, but is better suited for applications that require higher strength per weight ratio. Without sacrificing strength, A572 is lighter than the equivalent made with carbon steel, making it a great material for transmission towers, roller coasters, and bridges.
A588
A588 steel has a yield and tensile strength greater than 46,000 psi, higher than both A36 and A572. With similar elongation, A588 differentiates in its superior atmospheric corrosion resistance, leading to a longer life cycle. Therefore, A588 meets the specific needs of industries requiring outdoor solutions.
A514
A514 is a quenched and tempered alloy steel with a yield strength of 100,000 psi and an elongation between 16-18%. A514 is a high-performance structural steel, providing good weldability, and toughness at low atmospheric temperatures. Primarily, A514 is used to support heavy loads, in cranes and other high wear machine applications.
