Products characters

Round steel is divided into three types: hot rolled, forged and cold drawn. The specification of hot-rolled round steel is 5.5-250mm. Among them: 5.5-25mm small round steel is mostly supplied in straight bars, which are often used as steel bars, bolts and various mechanical parts; round steel larger than 25mm is mainly used to manufacture mechanical parts and seamless steel pipe billets.

H Beam
H-beam is a kind of economical section and high-efficiency section with more optimized cross-sectional area distribution and more reasonable strength-to-weight ratio. It is named after its section is the same as the English letter "H". Since all parts of H-beam are arranged at right angles, H-beam has the advantages of strong bending resistance, simple construction, cost saving and light weight in all directions, and has been widely used.
Angle Steel Bar
Steel Angles are the most basic type of roll-formed steel. They are formed by bending a single angle in a piece of steel. Angle Steel is ‘L’ shaped; the most common type of Steel Angles are at a 90 degree angle. The legs of the “L” can be equal or unequal in length. Steel angles are used for various purposes in a number of industries. Framing is one of the most common uses for steel angles, but steel angles are also used for brackets, trim, reinforcements, and many other uses. The larger the steel angle, the more weight and stress it can bear.
C/U Channel Steel
We carry U channel metals in aluminum, brass, carbon steel, and stainless steel. U channels are mainly used for two purposes: structural metal channels and architectural channels. Most metal channel sizes are available in full length and custom cut lengths.
