Shop drawings are usually created by someone in the fabrication shop to help other people in the shop to understand the design, size, and shape of a product. They are used to create new products or repair existing products.
Steel Shop Drawings: The steel shop drawings provide information about the dimensions of steel shapes called structural members, for example, columns, beams, and plates. The drawing will show not only the dimensions but also which side is up so that all of the members can be cut to accurate lengths. This will enable workers in the fabrication shop to construct steel structures that are safe and strong.
Fabrication Shop Drawings: Fabrication drawings show how a piece of material is cut out for a specific purpose - these pieces could be metal pieces or plastic parts. They may also show other operations like drilling, shaping, bending, punching, forming, and welding.
Anatomy of Steel & Fabrication Plant Drawing
There are many different types of steel and fabrication plants in the world. For this reason, it is necessary to know the layout of these plants to be able to make a drawing for them. There are various types of drawings that are used for steel and fabrication plants drawings, which include topographical plan drawing, detail plan drawing, general arrangement drawing, sectional elevation drawing, equipment arrangement drawing, etc.
Importance of these drawings:
The importance of these drawings can be understood by looking at the following points:
- Drawings help understand the layout and provide detailed information on dimensions
- Drawings provide information about how different parts fit together to make up a whole plant
- Drawings help find out the appropriate location for machines within a plant

Best Practices for Creating Your Own Shop Drawings
Many people want to create their shop drawings but lack the skills or knowledge. This article is written to show you how to make a fabrication shop drawing.
The first thing you need to do is gather the required information about the project. For example, what materials are needed? What are the dimensions of each section? What are the tolerances for each measurement? Whether any custom shapes need to be included in this drawing? And so on.
The next step is to sketch out a rough draft of what your drawing will look like using pencil and paper. The sketch should include all parts of your design and have dimensions listed next to each part so that it can be scaled accurately later on. After your rough draft has been created, you will then take measurements while making the necessary adjustments.
How to Read & Interpret Steel Shop Drawing | Essentials for Making Sense of the Symbols Used in the Drawing
Steel plants use a variety of symbols to convey information about the specific steel product being manufactured. These symbols have been developed by the American Iron and Steel Institute (AISI) and are used in all structural steel plants as well as fabrication plants. In this article, we will be focusing on reading and interpreting steel plant drawings.
To read a drawing, you must have an understanding of the symbols that are used in these drawings. The first step is to use a few symbols from the list below to interpret what type of drawing it is:
Steel fabricators need to know the basics of reading steel plant drawings. This will help them in understanding how to read and interpret these drawings.
There are two types of symbols used in the drawing, lettering, and symbols. Lettering is used to identify components while symbols are used to convey information about dimensions, tolerances, etc.
The drawings contain all the necessary information for fabricating a complete assembly or part. They include location diagrams, assembly layout diagrams, and profile views viewed from different angles (right side elevation, top plan).
Types of Lines and Symbols on Shop Drawings and What They Mean
The symbols on shop drawings are lines, circles, 45-degree angles, triangles, and squares. They are used to represent different types of work that need to be done.
The most common type of symbol on shop drawings is lines. Lines are used to drawing any type of straight line in a drawing or represent measurements in a drawing. Lines can also be used to represent an object that is made out of metal or wood because these materials cannot be drawn with circles or squares.
A circle is used to represent a round object like an axle or the container part of a pipe. A square represents an object that is flat like the baseplate for machine tools, the surface plate for machining centers, and the gantry beams for bridge crane systems. Circles and squares can also be used as shapes.
