Companies buying steel angles for structural and fabrication projects must consider the size before making the purchase. When selecting the right galvanised steel angle, start by evaluating the load requirements of your project to identify the suitable size and thickness.
Within the size of the L-angel and angle bar, it is essential to check the leg dimensions, thickness and the resulting weight per metre. For companies using galvanized steel angle, considering the core size and dimensions is essential. Here are a few factors your companies must keep in mind:
- Consider the surrounding environmental conditions to ensure you select the appropriate level of corrosion protection.
- Ensure the angle you select aligns with its intended structural role, whether it’s for robust frameworks or lighter partition work.
- For more complex applications, seeking guidance from an engineer is advisable.
- Don’t forget to consider factors such as fabrication needs, connection details, and material availability before making your final choice.
Below are the major criteria for the size of the angle that should be considered.
Leg length
This determines the flange that the angle will have, and it also shows the bearing or surface support capacity of the angle.
Thickness
This determines the strength of the section and the angle’s load-bearing capacity. This also determines the rigidity of the angle.
Weight per metre
This determines the derived size and the thickness of the angle, and depending on the same, the material cost is estimated. This also helps in determining the handling cost, structural weight, and design of the angle.
Material grade and galvanization
Checking this is essential as it ensures that your angle has sufficient strength and is resistant to corrosion.
Length
This is important for logistics purposes. In most cases, the MS angle is available in standard vs custom cut versions.
How to use the size when choosing MS Angle?
Determine the load
For industries that require MS Angle to support heavy loads, such as shelves, Mezzanine floors, and structural bracing, a larger-leg angle is necessary. For instance, the larger angles of 75×75×8mm or 100×100×10mm are essential as they give higher inertia and do not bend easily. As soon as the size and the thickness of the angle increase, the weight per metre also rises.

Check space constraints
Before choosing a steel angle, the business needs to understand the space requirements. If you’ve limited room space, you might choose a smaller leg size, such as around 30×30×3mm or 35×35×4mm. For instance, industries or manufacturers trying to fit the angle inside a metal frame or in a cabinet structure need to choose a smaller leg size so that it fits well. Sizes such as 30×30×3mm or 35×35×4mm are compact and lightweight. For instance, according to the weight charts of Shree Ji Steel, the weight of a 30×30×3mm is approximately 1.38 Kg/m, and the weight of a 35×35×4mm is approximately 2.11 kg/m.

Evaluating the weight and cost
Before placing an order for galvanized steel angle, it is important for the companies to work out how much the steel will weigh and how much it will cost. This helps companies stay within the planned budget and arrange transportation and installations accordingly. Depending on the angle of the steel, the weight per metre is listed. To estimate the total weight, companies are required to multiply the number by the number of meters required.
For instance, if the project needs 20 metres of 50×50×6 mm steel angle, then according to the weight chart of Shree Ji Steel, the size will weigh 4.49 kg per metre. Hence, 20 metres × 4.49 kg = 89.8 kg in total, or 0.0898 metric tonnes. The price of 50×50×6 mm steel angle, as offered by Shree Ji Steel, is ₹40,100 per tonne. Then the total price will be ₹40,100 × 0.0898 = about ₹3,600.
If the companies procuring the steel know the weight, then it helps them to plan and deliver the material.

The relation of length with logistics
Steel angles are usually supplied in standard lengths of around 11 to 13 metres when loaded in a trailer and 5.5 to 6.5 metres when loaded in a lorry. In simple terms, the steel angles that you’re planning to buy are mostly available in long pieces. However, they can be customised according to project specifications. Suppliers like Shree Ji Steel also offer a fixed length of 6-12 metres.
Thus, if the industries plan the lengths carefully they can save time and money in the long run. If standard lengths fulfil the project requirement, then it is better to avoid customisation. Ordering the exact length will save money and also facilitate seamless transportation to the factory site. Also, knowing the lengths helps you arrange proper transportation and handling — longer pieces may need special vehicles or lifting equipment for safe delivery and installation.
Tolerance and quality
When purchasing MS angles, the actual size and weight may not match the specifications provided by the suppliers. The difference is known as tolerance. For instance, the actual length of 50×50 mm may be slightly more or less, and a weight tolerance of ±5% is allowed by all suppliers. These variations are inherent to the manufacturing process. Hence, before buying, it is essential to check the quality standards offered by the supplier. For instance, Shreeji Steel adheres to IS 2062 specifications, ensuring that the steel meets the required strength and quality standards.
By following the above-mentioned points, industries should verify the reliability of the data and consider the lengths, weights, and prices when purchasing iron angles. If you’re looking for good-quality MS angles, get in touch with Shreeji Steel Private Limited. We are a prominent supplier of steel in West Bengal, offering a range of high-grade steel products in various shapes and sizes.
FAQs
Why should I choose Galvanized angle instead of a regular MS angle?
Galvanized steel angles have zinc coatings that make them corrosion-resistant. Hence, industries can safely use them for external fabrication and construction purposes. They are more durable compared to MS angles. They require less maintenance.
How does the weight tolerance of MS angles affect my project?
Tolerances are minor differences which occur naturally during the manufacturing process. It will not cause many issues for your project. However it is recommended to measure, cut and weld the MS angles by keeping a small margin so that the pieces fits properly.
