Choosing the Right I-Beams for Your Project

Adrianna Adamska 17 May 2024

High quality building materials and their selection for the requirements of the planned project have an impact on the success and durability of the finished project. One of the important elements of the structure are I-beams. How to choose I-beams for a construction project? Check the most important selection criteria!

What are I-beams?

I-beams, also known as H-beams, are characterized by a cross-section resembling the shape of two letters “T” connected at the bottom. These are construction elements with wide application in construction. Despite their small dimensions and low own weight, I-beams withstand high loads. Thanks to this, they are used, among others, for the construction of bridges, girders, as roof girders and wall construction elements in commercial and residential structures.

Types of I-beams and their application

I-beams are made of wood or steel. They can be divided according to their dimensions, which is why they are divided into:

  • wide-flange I-beams – they have wider flanges, which ensures greater stability in structures. These include HEA, HEB and HEM I-beams with dimensions from 90/100/5/8 to 180/180/8.5/14. Among wide-flange I-beams, there are light, normal and heavy I-beams;
  • standard I-beams (IPN) – these are the most commonly used I-beams, ideal for applications where high strength and stiffness are required, e.g. in the construction of bridges or roofs. Their dimensions are specified in the DIN 1025 standard;
  • European I-beams type I (IPE) – this type of I-beam is mainly used in the industrial sector, they are used, among others, for the construction of heavy machinery. The dimensions of European I-beams range from 80/46/3.8/5.2 to 240/120/10/12.

How to choose the right I-beams?

Before you decide to buy specific I-beams, consider the requirements and loads that the finished structure must cope with. Properly selected I-beamswill ensure high durability and safety of the building. What should be considered when choosing I-beams?

  • Purpose of I-beams

You can use I-beams, among others, in wall, roof and floor structures. Think about what you need the elements for and what task they should fulfill. Can you use wooden I-beams to strengthen the walls in a single-family home, or does your project require the use of steel beams? For example, I-Beams manufactured by Dudek Group are perfect for single- and multi-family housing.

  • Structure load

Estimate the type and amount of load that the finished structure will have to withstand as accurately as possible. I-beams are available in various sizes, which affects their strength and the durability of the construction project. Choose a beam size that will adequately reinforce, for example, the floor or roof and ensure the stability of the structure.

  • Resistance to external conditions

Also pay attention to the location of the project and the microclimate in the immediate vicinity. I-beams should withstand unfavorable weather conditions, such as strong winds and storms, frequent precipitation, or significant temperature fluctuations. I-beams can be coated with special preparations that will make them less exposed to moisture. Dudek I-Beams can be additionally filled with insulation, which will ensure appropriate thermal conditions inside buildings.

  • Purchase cost

Remember that the cheapest solution does not always pay off, especially in the long run. I-beams of too low quality may require expensive repairs or replacement after some time. It is safer to invest in more expensive but more durable I-beams, which will also provide greater safety when using the structure.

Summary

When buying I-beams, it is worth considering not only their price, but above all their parameters, which affect the safety and durability of the finished structure. Attention should be paid to, among other things, the material of the I-beams, their strength and construction, as well as the challenges they will have to cope with.
