How to Identify High-Quality Steel Products from the Philippines

How do you identify high-quality steel products from the Philippines?

  1. Stress test
  2. Stiffness test
  3. Strain test
  4. Magnet test



The quality of materials is crucial when building something. This is true for projects involving steel products. Using only the highest-quality steel in buildings or projects ensures that the end product is also excellent in quality.

Identifying steel products usually requires a comprehensive and standardized test in order to reliably determine their quality. But because not everyone has access to a steel testing facility or laboratory, this post has gathered some of the simple ways you can quickly assess the quality of steel products.

Here are a few ways to identify high-quality steel products from the Philippines.



Stress Test

Stress test

Steel products can be used for many different applications. You need to be able to know how far you can pull or stretch the steel product before it starts to unravel.

Putting the steel product you intend to buy through a simple stress test reveals if there are any holes and empty cavities or any sudden changes in its composition. Information like this is valuable especially if you intend to use the steel product in any kind of construction.

Steel is a dependable, tough, and rust-resistant material. Buying a steel product with defects can eventually cause disaster down the line. Avoid the pitfalls of buying cheap steel products by examining the level of stress the material exhibits.



Stiffness test 

Another easy way to determine the quality of your steel product is to try and bend it.

Bending any piece of material reveals its stiffness level. If your steel product snaps in two pieces after reaching a certain point, it most likely has a low stiffness level. On the other hand, if your steel product bends but does not snap, the material it is made of has a high stiffness level.

Establishing how much your steel product can bend before it breaks is important so you can be sure that the metal does not fall apart easily. You can also prevent your building or project from breaking when extreme pressure is applied if you know its stiffness level.



Strain test

Testing your steel product’s strain lets you know how much it can be stretched or compressed in comparison to its original size.

For example, if a steel bar can be stretched to twice its original length, then it can be said that this material has a 100% engineering strain.

Another way to test the strain of your steel product is a compression test. If possible, take your steel product between two plates and apply force by moving the plates together. Through this test, you can find out the strength, proportional limits, and elasticity of your steel product.



Magnetic test

Magnetic test

The magnetic response test is widely accepted by some but sometimes misunderstood. Being magnetic or nonmagnetic does not necessarily mean a steel product is better or worse. The magnetic test checks for the kind of steel you have.

For instance, ferritic steels are strongly attracted to magnets while annealed austenitic steels are not.

Cold annealed austenitic steel products, however, can develop a magnetic response and may be affected by a magnet. Permeability, or the ability of a material to support a magnetic field within itself, is relative to the strength of the magnetic effect. Products made with mild steel has a relative permeability between 200 and 2000.



Key Takeaway

 Using only high-quality steel products are important in any kind of application, whether it is for small furniture or large skyscrapers. Not all steel products in the Philippines are high-quality, sometimes through no fault of the vendor at all. With the increase of low-cost and low-quality steel products in the market, it falls to the customer to do their due diligence to get their money’s worth.
