What Exactly is Sheet Metal Fabrication?
Sheet metal fabrication refers to the process of transforming flat sheets of steel or aluminum into various metal structures or products through cutting, punching, folding, and assembling. Sheet metal can be shaped by cutting, burning, bending, or stretching, using specialized tools and metal fabrication techniques.
During the sheet metal fabrication process, tools such as band saws and chop saws are utilized to ensure precise and even cutting. Cutting torches are also employed for efficient cutting of larger sections of sheet metal.
Press brakes play a significant role in sheet metal fabrication by facilitating the creation of sharp bends and angles. Different types of press brakes are available, each serving specific functions and purposes.
Welding is another crucial aspect of sheet metal fabrication. Once the components are formed, they are assembled and tack welded together. Various welding techniques are employed to prevent warping or other abnormalities. These techniques may involve covering the metal with sand during the cooling process, implementing specialized straightening sheet metal processes, welding in a staggered manner, and using sturdy fixtures.
To rectify any defected metal, an oxy-acetylene torch can be used to apply heat gradually and eliminate abnormalities.
The finishing touches for the fabricated metal typically involve sandblasting, priming, and painting. This ensures an aesthetically pleasing appearance and prepares the metal for delivery to the client.

How the Sheet Metal Fabrication Process Works?
Sheet metal fabrication involves the transformation of raw materials, such as steel, aluminum, or copper, into desired shapes through cutting, bending, and forming. Here is an overview of the typical steps involved in the process:
Design: The project begins with the design stage, where designers create initial sketches or 2D/3D models of the product using computer-aided design (CAD) software or by hand. Factors like product use, dimensions, tolerances, and material requirements are determined at this stage.
Cutting: Laser cutting is commonly used to accurately cut the sheet metal according to the programmed design. Laser technology ensures precision and allows for intricate shapes and patterns.
Bending: The bending process, often done through CNC folding, utilizes machines like manual press brakes or automated panel bending machines. The sheet metal is clamped and pressure is applied to achieve the desired curvature.
Forming: Forming involves reshaping the material without reducing its mass. It bends or deforms the metal into the required shape through specialized tools and processes.
Types of sheet metal forming process: Bending,Stretching,Deep Drawing,Roll Forming,Spinning, Shearing, Punching and Hemming.
These are just a few examples of sheet metal forming processes. The selection of the appropriate process depends on the desired shape, complexity, material, and volume of production.
Welding: Various welding techniques are employed in sheet metal fabrication. MIG welding is suitable for thicker materials, while TIG welding offers greater control and precision for thinner materials. Robotic MIG welding provides automation, and spot welding utilizes electrical resistance.
Finishing: Finishing enhances the durability and aesthetics of the metal products. Surface preparation, polishing, powder coating in different colors, anodizing, passivation, and laser marking are common finishing techniques applied to protect against corrosion and add visual appeal.
Assembly: In sheet metal fabrication, assembly involves bringing together the fabricated parts to create the final product. This includes packaging and preparing the product for delivery.
At RDL, we offer subcontracting services, providing individual parts or complete electro-mechanical assembly for a comprehensive end product.
This streamlined process ensures efficient and precise sheet metal fabrication, resulting in high-quality products tailored to specific requirements.
Types of sheet metal fabrication
Sheet metal comes in various types, each with its unique characteristics and applications. Here are some major types of sheet metal:
Aluminium: Widely used in automotive parts, electrical devices, and cooking vessels. It offers advantages such as a favorable strength-to-weight ratio and high conductivity.
Aluminised Steel: Combines the strength of carbon steel with the corrosion resistance of aluminum. Aluminised steel sheets are used in high-temperature environments, such as kitchen appliances.
Carbon Steel: Commonly used in industrial and consumer markets for a range of products. Carbon steel is an alloy that gains hardness and strength through heat treatment.
Copper: Used for sinks, roofs, rain gutters, and doors. Copper exhibits higher electrical and thermal conductivity compared to aluminum but may be relatively more expensive.
Galvanised Steel: Sheets of galvanised steel find applications in automobile bodies, water pipes, fences, roofs, and staircases. It is made by coating steel with zinc, providing enhanced corrosion resistance.
High-Strength Steel: Often used for military armor plates, high-strength steel is produced by alloying with elements like carbon, manganese, and copper to improve its hardness.
Stainless Steel: Utilized in kitchen vessels, storage tanks for chemicals, and food processing machinery. Stainless steel offers superior corrosion resistance, fire and heat resistance, strength-to-weight ratio, and manufacturability.
Titanium: Found in aviation parts, medical equipment, and construction elements. Titanium is valued for its high strength-to-weight ratio, corrosion resistance, and recyclability.
Understanding the different sheet metal fabrication types allow for informed material selection based on the specific requirements of a project.
