Sheet Metal Chassis Fabrication Process

Technically, fabrication process of a typical sheet metal chassis is imperative in ascertaining the general efficiency of the entire unit.

Hence, you must get it right by understanding all the core aspects needed in the process.

To attain a successful sheet metal chassis process, it would be ideal to follow these steps;

            Step 1: Selecting Sheet Metal Chassis Design

It involves the conceptualization of an idea of what you desire the sheet metal chassis to look like.

Of course, these components come in a wide range of designs and styles, depending on the actual application.

After choosing the right design, it’s now time to configure its right prototype for accuracy when it gets to production.

            Step 2: Establishing The Dimensions

You have to know the exact size of sheet metal chassis you are manufacturing.

Figure out the specifications to enable you to determine the sketch of this component.

Ensure the dimensions are in line with other components you will be mounting on the frame.

            Step 3: Designing

This stage entails including the primary idea of what you need to attain with the designer’s concept.

It may include coming up with a 3D model of the specific desired sheet metal chassis.

At this stage, analysis of drawings and other calculations takes place to ensure conformation to the design specifications.

It then goes to the final comprehensive design to determine the load limitations and stress levels.

Hence, the details derived from this phase plays an integral role in selecting the most suitable fabrication process.

            Step 4: Material Selection

The ideal material is selected based on the actual application the sheet metal chassis is designed for.

Often, the environment, load restriction and stress level are used to establish the best material for the component.

            Step 5: Material Sizing

Of course, these materials usually come in large plain sheets.

Hence, to obtain the right size for the specific sheet metal chassis, you will need to cut it to size.

You can use various techniques to cut the material to the right size.

For instance, you can use plasma cutting, CNC cutting, laser beam cutting or waterjet cutting.

Alternatively, you can use photochemical machining process to cut the material to size.

The bottom line is ensuring the specific technique you use for material sizing guarantees best results efficiently and conveniently.

            Step 6: Sheet Metal Chassis Forming

Fabrication, in this case, involves reconfiguring and reshaping the specific sheet metal chassis to attain the desired multi-axis forms.

It entails several processes depending on the actual design and the desired shape of the chassis.

Some notable forming processes for this component include the following;

  • Hemming

It involves a rolling metal shape edge to offer a relatively smooth and sturdier edge.


You can open hems to leave air space within the bends or closed where the folded metal is pressed tightly against itself.

Hemming is essential since it eliminates sharp edges from sheet metal chassis.

  • Bending

You can bend most materials used for making sheet metal chassis along a straight axis using a wide range of presses.

Such shapes can range from gentle curves to sharp corners using press brakes.

Rolling and forming techniques produce open and or closed single-axis curves in an unbroken bending operation.

  • Blanking

This method can be divided into different categories such as shear cutting, counting punching, general punching, laser cutting and wind-cutting.

Ordinarily, the processing technology of blanking is often different since various sheet metal chassis require different fabrication needs.

  • Stretching

It is a process that uses English wheel, stretcher or hammer to pull the sheet metal chassis apart.

In this case, this component is stretched and bent over die simultaneously.

Hence, it becomes easy to obtain the desired curves on the particular sheet metal chassis material.

Stretching method uses a stretch press where sheet metal chassis is wrapped up along the edges and pulled by hydraulic force.

Step 7: Assembling Sheet Metal Chassis

This step entails pulling the sheet metal chassis parts together to form a single solid unit.

You can use several techniques to assemble this component, but the commonly used ones include the following;

  • Welding

It is a process that uses heat to melt a sheet metal chassis section to enable it to fuse with another part by incorporating a filler material.

Some typical ways often used for welding this component include; TIG, MIG, robotic and spot among others.

Essentially, welding entails melting the sheet metal chassis metal base by high heat while adding filler material.

The heat emits high temperature and forms a pool of molten weld, which upon cooling forms a joint, possibly stronger than the primary material.

In other instances, pressure is used to form the weld and form the weld is often attained by same pressure or combination of heat.

Moreover, you can use shielding gas to protect melted and filler metals from oxidation.

  • Brazing

More or less similar to welding, but the only difference is that brazing melts filler compound without necessarily melting sheet metal chassis material.

As such, brazed alloy in form of molten filler metal solidifies at the joint.

  • Riveting

It comes in handy in fastening different pieces to form a solid sheet metal chassis unit.

You can use different types and sizes of rivets depending on the dimensions and design of the sheet metal chassis.

Riveting is advantageous since it can fasten different materials together in areas other processes cannot necessarily access.

  • Adhesives

Structural adhesives are ideal for creating strong assemblies in sheet metal chassis.

As such, it won’t be necessary to use mechanical or welding fasteners to enhance the joints’ structural integrity.

Using adhesives is advantageous since it spreads across the whole bond joint, and this increases fatigue resistance and inhibits corrosion.

Surface Finish For Sheet Metal Chassis Parts

It is imperative to coat sheet metal chassis using a suitable surface finishing compound to create a protective layer.

Besides, the surface finish coatings enable other secondary processes on the component, such as paints, to easily adhere to the material.

The primary surface finishing options you can always use on sheet metal chassis parts include the following;


It is a common surface coating method that involves applying protective zinc, steel or iron coating on sheet metal chassis components.

The aim of this sheet metal layering method is to inhibit the chassis material from corroding and to enhance its durability.



This method uses chemical substances to form a metallic layer on the sheet metal chassis’ surface.

It is beneficial since it enhances resistance to corrosion, which is vital in enhancing durability of the component.

Powder Coating

It is a surface coating technique that integrates a strong plastic powdery compound on surface of sheet metal chassis.

You can use it, particularly for sheet metals chassis designed for relatively harsh applications, since it exhibits immense corrosion resistance.


This coating method entails using an electrolytic passivation process that, in essence, enhances an oxide layer on sheet metal chassis material.

Vapor Deposition

In this surface finishing technique, sheet metal chassis is deposited into a chemical compound using gaseous phase of depositing material.

Factors Affecting Cost Of Sheet Metal Chassis

When purchasing sheet metal chassis, you are likely to find it at different price rates.

Such rates are based on a wide range of factors but mainly the following;


Sheet metal chassis price is significantly determined by the specific material used to make it.

Ideally, different materials have various properties such as strength, durability, lightweight, weldability and resistance to various environmental compounds.

Hence, sheet metal chassis material with superior qualities is likely to be costlier than one with relatively inferior properties.


Often, the actual design of a sheet metal chassis is dependent on the components to be attached to it.

Therefore, chassis with complex designs are bound to be more expensive since they entail a lot of details to produce.

On the other hand, simple designs are easy to produce and do not require detailed input; thus tend to be cheaper.


In many instances, the suppliers calculate the unit price based on the specific number of pieces you are purchasing at a time.

When you purchase sheet metal chassis in bulk, many manufacturers often provide better discounts.

On the other hand, buying fewer pieces is likely to attract relatively high unit prices hence expensive, in the long run.


Different producers of sheet metal chassis often peg their respective products at different rates.

Ideally, this is often based on various factors such as brand positioning in the market, quality and general reputation.

As such, sheet metal chassis from popular manufacturers tend to be more expensive than those from relatively less known producers.

Benefits Of Sheet Metal Chassis

Some advantages of choosing sheet metal chassis include the following;

  • It offers a cost-effective option since the materials for making the unit tend to be more affordable than most non-metal alternatives.
  • You can easily automate and produce sheet metal chassis easily using several modern fabrication techniques directly from CAD models.
  • Producing sheet metals chassis in bulk is easier since the fabrication process is highly scalable.

Hence, it makes it easy to get an ideal number that suits your demands accordingly.
