Gratings are a drainage component used to cover open drainage channels. The form is a rectangular bar with rectangular perforations. Gratings are often made of metal materials such as cast iron and steel plates. So, in this article, we will compare cast iron gratings vs steel gratings.
Comparison of cast iron gratings vs steel gratings
Strength
Gray cast iron and ductile iron are used to make cast iron gratings, which have firm, ductile qualities, can dampen vibrations, and can sustain heavy loads. Cast iron gratings are therefore more appropriate for projects in locations where heavy-load vehicles frequently pass through.
Cast iron gratings are classified into three types based on their strength or load capacity: heavy duty, medium duty, and light duty. For heavy-duty vehicles such as aircraft and trucks. Medium duty is appropriate for medium loads such as family cars and light commercial vehicles. Meanwhile, a light duty applies to places that are not passed by anything and locations that are passed by light loads such as pedestrians.
Steel gratings are also manufactured of sturdy steel plate material. However, unlike cast iron, if vehicles are constantly driven over it, this material will distort over time. A grating that has been curved is undoubtedly uncomfortable when it is passed, isn’t it?
Usage Location
Cast iron gratings are commonly used in drainage systems in airports, highways, underpasses, hotels, shopping malls, flats, and any other building with drainage channels. Cast iron gratings can be used in a variety of applications due to their three different varieties (heavy duty, medium duty, and light duty). You only need to adjust it to the load that flows through that location.
Steel gratings are typically utilized in residential and industrial regions or facilities with light loads.
Design (dimensions and motifs)
The type, design, and size of cast iron gratings are all customized. This is due to the fact that the site conditions for each project vary, such as the size of the drainage canal and the vehicles that pass through it. As a result, cast iron gratings are made to order based on the specifications of each project.
Cast iron gratings can be customized with picture and writing motifs. Regional icons or business logos might be used as image motifs. Meanwhile, the textual motif is typically a company name or the name of the city in which the project is located.
Steel gratings are typically available in certain sizes. As a result, the drainage system is built around the size of the steel gratings that are currently available. Because the design is conventional, you cannot include a logo image or write your company name.
Manufacturing
Metal casting or foundry is used for manufacturing cast iron gratings. The iron is melted before being placed into the mold. This method of production allows us to produce gratings in solid shape without any connection pieces that can break.
Meanwhile, steel gratings are formed from steel plate material that is cut into pieces and welded into a grating shape.
Lifetime
We can ensure that if you order cast iron gratings with specifications that match project site conditions, the cast iron gratings will last for tens of years, even a lifetime.
As previously stated, if steel gratings are continuously loaded, they will eventually deform or bend. As a result, the steel gratings may not be used for a long period of time.
Price
The final comparison is based on price. The price of cast iron gratings and steel gratings is comparable.
Cast iron gratings are priced per unit rather than per kilogram or per meter. Steel gratings, on the other hand, are often sold per meter.
So, choose cast iron gratings or steel gratings?
Based on the comparison of cast iron vs steel gratings above, we can conclude that cast iron gratings are appropriate for all projects because it comes in three different types (heavy duty, medium duty, and light duty) that you may select based on your needs in the project site. Cast iron gratings are better in terms of aesthetics because you can request a logo image motif or company name lettering. Do you want to order cast iron grating right now?
