Steel is an everyday miracle, essential to modern life in thousands of ways. Steel is capable of withstanding immense pressure and doesn’t succumb to metal ‘fatigue’. Consequently, its applications are extensive and it is used in everything from cars and bridges to small tools or household items. Knowing exactly which kind is suitable for you means that when purchasing from steel suppliers in Gauteng, you should ideally ask about the stress, stiffness and strain levels. A good manufacturer will understand these specifics and will be able to help you secure the best quality steel of correct specification and fabricated to suite the job at hand.


The stress grade of a metal determines how far it can be stretched or pulled before permanent damage sets in through holes or faults in the cross-section. This refers to its tensile strength. Similarly, the extent to which it can be compressed is referred to as its compressive strength. This is vital information when purchasing steel in Gauteng as durability and strength are fundamental requirements of the alloy. Any faults in the alloy will create weak points and may sabotage the entire project and endanger people. Always find out the stress level of the metal you are buying and avoid purchasing cheap and inferior materials from steel suppliers in Gauteng.


Metals are crafted to be able to bend to a certain point before snapping. The stiffness level is determined by how much the material can bend before snap point. If the stiffness level is low then the material will snap with less force. It’s easy to understand why this is an important factor when selecting steel suppliers in Gauteng, as a metal with a low stiffness rating could mean a collapsed roof or broken tools and equipment. There are some applications that may permit use of steel with low stiffness. Your service provider will be able to offer you wise council when it comes to making the appropriate selection for your application. Inferior steel products, which are brittle, will break easily, but a ductile alloy can withstand great forces such as bending.


The strain level on a metal is defined by how much it can be compressed or stretched compared to its original size. This clearly indicates the strength, limitations and elasticity of the metal and will dictate what the metal should be used for. For instance, if a rod or bar of metal can be stretched significantly, it has a very high strain level. Likewise if the metal can be compressed considerably, then the strain level of the metal is also considered high.

Always endeavour to establish these vital factors when purchasing from steel suppliers in Gauteng. Cheap or poor quality steel can be dangerous and will cost you more in the long run. Contact Genesis Steel for approved steel products including hot rolled sheets and sheet plates.
