Selecting the right kind of steel for your job requires you to consider a number of factors: both current and future. Sometimes you will be able to do this yourself with the help of a detailed product guide, but most often it will be better to consult a professional.
How many different kinds of steel are there?
Not only are there many different types of steel and steel products, many of these products will have been graded for a number of different factors, including malleability, strength and structural gradings. So, you will need to understand the grading nomenclature as well if you are to make the correct choices.
Steel Gradings
When ordering steel the following needs to be considered to ensure you specify the right product:
Product and end use
Just about every steel product type will have characteristics suitable for a range of functions, such as framing and bending, and different levels of corrosion protection or strength performance. Therefore there are likely to be a number of different products which will be suitable – to some extent – for you requirements. When ordering your steel products you need to think, however, about which product best suits the purpose of your end application.
Dimensions
Specify the width and thickness in millimetres, to two decimal places. You should also quote the required measurement tolerance – usually as Class A for standard tolerance or Class B for tighter tolerances.
Pack mass
Pack mass specifications together with the pack type required, this needs to be decided for each product you intend to order.
Coating class
When ordering coated sheet or coil products you will need to specify the required coating thickness, colour and surface protection. Your requirements should be stated in metric thicknesses, to two decimal places and should also specify the base metal required.
Quantity
Most steel orders are expressed in metric tonnes, however you should speak to your steel merchant or steel distributor about minimum order quantities, particularly if you are ordering a specialty grade of steel or coating.
Certification
If your job requires a steel product with individual test certificates, you will need to specify this when you place your order. This level of certification is more common for coil rather than plate products.
Lead time
Lead times will often vary between products or due to individual specifications. You should always discuss lead times with your steel merchant as early as possible so that you are not disappointed.
When choosing steel for your next job, if you need to consult a professional, start with your steel merchant or steel distributor, they should have all the knowledge to help you make the right choice.
