Difference Between Steel Sheet vs Steel Plate vs Steel Foil

Dear Readers,

Difference Between Steel Sheet vs Steel Plate vs Steel Foils are as follows. Thickness is a main criteria for all

Metal Foil

Metal foil is a very thin sheet of metal that has been hammered or rolled flat. Metal foils can be made from any type of metal, although the most commonly found foils are aluminum foil and gold foil. Aluminum foil typically has a thickness of .03mm, although any sheet of metal with a thickness of less than 0.2mm is considered a foil.

Steel Sheet

Steel Sheet is any metal that is thicker than a foil and thinner than 6mm, the thickness of a metal plate. Steel Sheet is often used for building structures that do not require durability. It is also often corrugated or diamonded for additional strength without increasing weight. Corrugation is the creasing of the metal at regular intervals to form ridges, and diamonding is the addition of diamond ridges that add structure to the metal.

Steel Plate

Once the steel is more than 6mm thick it is known as steel plate. Steel Plate is used in applications where durability is more important than saving weight. It is used in automobiles where durability is required to pass crash testing.

The Difference

The only difference between sheet and plate steel is the gauge (thickness) of the metal. They both have very different uses, depending on the varying durability and weight requirements for different projects.

Unit Weight of Parallel Flanged Channel

Parallel flange channels are more commonly known as PFC or C-section. A PFC is a vital part of the structural steels used in the construction of buildings and large-scale steel fabrications. 

The Parallel Flange Channel is praised for its ability to provide increased strength and durability to steel projects. Typically used as columns or as support for floor joists and have a highly desirable load bearing profile. You may also find PFCs used in conjunction with RSJ steel beams, universal columns and all forms of structural steel.

Unit Weight of parallel flanged Channel is as follows

Special Purpose Bolts

Dear Readers,

Typical examples of the bolt for special purposes are as follows:

Stove Bolt

A stove bolt has a round flat head which is beveled on the underside to fit a countersunk hole, it is provided with a slot on the head, as shown in the figure.

For screwing the bolt into a nut by means of a screwdriver. This is used for assemblies where precision is of no great importance, and it is desirable to have the head of the bolt flush with the surface of the work.

Carriage Bolt

Domed, enlarged head shape and Designed to keep bolt from pulling through suitable tool.

This is used for fastening wooden parts together or for fastening metal parts to wood it has squared portion directly under the head to prevent rotating when the nut is tightened or slackened. A carriage bolt is shown in the figure.

Hook Bolt

The hook bolt, shown Fig. is used in semi-permanent fastening in concrete.

This is also used in cases where there is no room for a bolt hole through one of the pieces to be connected, or in cases where a bolt hole would seriously weaken a piece. So the hook bolt is used for attaching shaft hangers to the flanges of joists and girders.

Expansion Bolt 

This type of bolt is used in attaching parts to brick, stone or concrete walls and floors hee bolt has an internally threaded split sleeve which is slipped into a hole made in the wall and then expanded by running in the screw. This is shown in Fig.

Foundation or Rag Bolt

The rag bolt, shown in Fig. is used for fixing into the stone concrete foundation, the head is wider at the bottom than at the top, and is led into a tapered hole. 

The tapered head is cut in an uneven manner (jagged) and moulted lead or sulfur is poured into the taper hole to fill the space between the lead and the stone or the concrete as the case may be. Where great strength is required, four parallel bars or keys are used in addition.

Eye-Bolt

The eye-bolt, shown in Fig. is very commonly used for lifting purpose. It is screwed or turned inside a threaded hole on the top of the machine.

Electric motors and medium and lightweight machinery are equipped with one or more eye-bolt so that they may be readily lifted and moved by an overhead crane.
