Complete Size Chart of Stainless Steel Angles in MM and Inches
Stainless steel angle sizes play a crucial role when picking the right material for any project.
Because of this, the choice should never feel like a small decision.
Often, it plays a decisive role in determining the success or failure of a project.
Steel angles are used everywhere.
- They support structures.
- They contain the frame.
- They add strength where strength matters the most.
Therefore, it has become necessary for someone who wishes to work with stainless steel or experiment in their workshop.
- It prevents you from making mistakes.
- It also helps save time and money.
This guide is one that clearly explains everything.
Primarily, the book contains a complete size range chart for stainless steel angles measured in mm and inches.
Thus, you can order the correct size without the least hesitation. Altra Enterprise is a supplier of stainless steel angles to the Indian market.
Consequently, this article has been written from actual supply experiences. Not theory.

What Is a Stainless Steel Angle Sizes?
A stainless steel angle has the shape of the letter “L”.
It has two straight sides.
These sides are joined at a right angle.
Since SS is rust-resistant, the angles have a long life.
They are able to manage moisture and heat better. This is because they find applications in various sectors. Example: Construction, Fabrication, and Manufacturing. Moreover, the stainless steel angles can be easily cut and welded. They are therefore useful in everyday life.
Significance of Stainless Steel Angle Sizes
The Strength is influenced by size.
Although many do not consider this initially.
If this angle is too small, then it might bend.
On the flip side, a larger size means an increase in cost.
This is because one needs to choose the right size.
It increases safety.
It also enhances performance.
When consumers search for stainless steel angle dimensional information, they naturally seek straight answers.
For instance,
- Leg width
- Thickness
- Length
- Weight
Hence, the proper size chart comes into play here.
Kinds of Stainless Steel Angles
Stainless steel angles can be divided, according to the length of the legs, into the following
There are two Types.
Equal Stainless Steel Angles
In equal angles, both legs are of equal length.
As in, 40 × 40 mm or 2 × 2 inches.
As the sides are equal, the pressure is balanced.
Therefore, these are angles that are easy to design with.
They are commonly used for frames and supports.
They are readily available in most instances.
Unequal Stainless Steel Angles
In unequal angles, the two legs are not of equal length.
For instance, 50 x 30mm or 3 x 2 inches.
They are useful when the loads are uneven.
Equations
As such, these brackets are ideal for brackets and edge supports.
However, a selection needs to be made properly.
However, balance is always relevant
Standard Lengths of Stainless Steel Angle Sizes
In most cases, stainless steel angles are shipped in predetermined fixed lengths.
The most typical length is 6m.
Occasionally, they may be available for 3 meters or 12 meters.
However, this depends upon stocks.
Standard sizes are usually common, so prices are lower.
They also have shorter delivery times.
Custom cutting is available.
However, this might increase the time and expense.
Understanding Thickness
Thickness is another important factor.
It affects both strength and weight.
As thickness increases, angle beams support heavier loads.
However, thicker sections also weigh more.
In contrast, smaller angles are easier to handle.
Because of this, they suit lighter applications.
At the same time, they may not perform well under heavy loads.
Typical thickness values include:
3 mm
4 mm
5 mm
6 mm
8 mm
10 mm
Therefore, thickness must always match the application.
Below, you will find details on stainless steel angle size tolerances in mm and inches.
After that, a complete size table is provided for easy reference.
These stainless steel angles are commonly supplied by Altra Enterprise.

Weight Consideration for Stainless Steel Angle Sizes
“Weight has a much bigger impact than most people think.”
It impacts handling and transportation.
As the size rises, the weight rises too.
This also applies to thickness.
For instance, a small angle can be easily lifted.
“However, when the angle of reflection is large, it
As a result, the weight per meter is to be checked.
It assists with logistics.
At Altra Enterprise, weight information is available upon request.
All this makes it easier for consumers to understand.
Common Grades Offered
“Size is important.”
“However, grade choice is also important.”
Various conditions call for different grades.
For example:
- General use grade: 304
- 316 grade for coastal or chemical exposure
- 202 Grade for Cost-Sensitive Tasks
All sizes are generally available in these grades.
However, the availability of these items may
Thus, checking the Stainless steel grade and size simultaneously is prudent.
Applications on the Basis of Size
Varied sizes have variant functions.
These are some examples you are likely familiar with:
Small Sizes
Smaller sizes for the angle made of stainless steel include 20×20mm and 25×25mm.
They are light. They are easily operated.
Typical applications include:
- Shelving
- Furniture frames
- Light supports
With the load being low, a thin thickness is preferred.
Medium Sizes
Medium sizes are 40 x 40 mm and 50 x 50 mm.
They are strong and controllable.
They are used in:
- Fabrication work
- Frames for equipment
- Railings
Sizes that allow for the balance of strength and cost:
Large Sizes
Large sizes: 75 × 75 mm, 100 × 100 mm.
They carry heavy loads.
They are utilised in:
- Structural frames
- Platforms
- Industrial supports
Due to the weight, the handling process has to be carefully planned.
How to Choose the Right Size
Selecting the correct size does not have to be complicated.
There is a simple way.
Next, consider the load.
A heavier load requires a bigger size.
Now, consider the environment.
Moisture and chemicals require better grading.
Next comes a check for availability
Also, standard sizes help save time.
Finally, a comparison related to cost and weight
Balance is a consideration
If you are unsure, consult with the supplier.
A guide prevents errors.
Most manufacturers follow international stainless steel material standards to keep angle sizes consistent and reliable across projects.

Frequently Asked Questions About Stainless Steel Angle Sizes
FAQ 1
What are the standard stainless steel angle sizes?
Standard stainless steel angle sizes include both equal and unequal angles.
In most cases, common sizes start at 20 × 20 mm.
From there, they go up to 100 × 100 mm.
At the same time, thickness usually ranges from 3 mm to 10 mm.
As a result, these sizes suit both light and heavy applications.
In addition, suppliers typically provide angles in 6-meter lengths.
Because of this, handling and fabrication become easier.
FAQ 2
What is the difference between equal and unequal stainless steel angles?
Equal angles have both legs with the same width.
Because of this, they provide balanced support on both sides.
In contrast, unequal angles have one leg wider than the other.
As a result, they work well when one side needs extra strength.
Therefore, builders often choose equal angles for uniform loads.
However, they prefer unequal angles when the design demands added support on one side.
FAQ 3
Are stainless steel angle sizes available in both mm and inches?
Yes, stainless steel angle sizes are available in both mm and inches.
In India, buyers usually place orders in millimetres.
However, drawings and older references often use inches.
Because of this, knowing both units becomes important.
As a result, buyers can compare sizes easily.
More importantly, they can avoid costly ordering mistakes.
FAQ 4
How do I choose the right stainless steel angle size?
First, check the load the angle must carry. Next, consider the environment where it will be used. Then, choose the thickness and size accordingly. If unsure, consult a supplier before finalising.
FAQ 5
Which grades are commonly used for stainless steel angles?
The most common grades are 304, 316, and 202.
- Grade 304 is used for general applications.
- Grade 316 is used for corrosive environments.
- Grade 202 is chosen for cost-sensitive projects.
FAQ 6
Do stainless steel angle sizes affect weight?
Yes, size and thickness directly affect weight.
As size increases, weight also goes up.
Similarly, thicker angles weigh more.
Because of this, weight affects handling and transport costs.
Therefore, always check the weight per meter before placing an order.
FAQ 7
Are custom stainless steel angle sizes available?
Custom sizes are available on request.
However, they usually take more time to produce.
In contrast, standard sizes are easier to source.
As a result, they cost less and ship faster.
Therefore, for urgent projects, standard sizes are the better choice.
