C300-shaped steel is widely used to make roofs for houses, prefabricated houses, purlins for warehouses, factories, etc. However, not many people still understand this type of shaped steel. This makes choosing and buying C300-shaped steel more difficult. Understanding this, Bao Tin Steel has compiled information about this type of steel in the article below.
What is C300 shaped steel? What are the characteristics?
C-channel steel, also known as C purlin, is a shaped steel with a cross-section similar to the letter C. With C300 steel, the height of the cross-section is 300mm. C300-shaped steel is produced according to JIS G3302 and ASTM A653M standards. Along with that, the common thickness ranges from 1.2mm to 3.2mm.

C300-shaped steel has load-bearing capacity, high durability, and good corrosion resistance. with these outstanding advantages, C-channel steel is used in many projects and applications such as:
- Making roofs, floors, and purlins supports scaffolding systems at construction sites.
- Making prefabricated steel house frames and prefabricated houses.
- Making steel piles to reinforce building foundations.
- Making truck frames, car frames, machinery, and equipment frames.
Types of C300 shaped steel on the market
Currently, there are two main types of C300 steel: black steel and galvanized steel. In there:
- Black C300 steel is steel produced from hot-rolled steel billets with a black surface. It has good strength and high durability but is susceptible to corrosion and rust. Therefore, it is chosen for indoor applications with little exposure to harsh conditions.
- Galvanized C300-shaped steel: This is also a type of steel produced from hot-rolled steel billets. However, it is plated with an additional layer of zinc on the outside. In addition to its good bearing capacity, it also resists corrosion better than black steel.

In addition, C300 purlins can also be customized according to thickness. The usual thickness is about 1.2–3.2 mm. But in larger projects that need higher load-bearing capacity, C300 steel with a thickness of 3.2–14 mm will be used.
