Rolled metal products are metal products that have been rolled (hot and cold) on machines. The most demanded is the metal sheet , you can buy metal sheets both at retail and in bulk, the scope of its application is diverse:
- Industry.
- Under construction.
- In agriculture.
- At home.
Sheets are also divided according to two production methods:
- Hot-rolled - the peculiarities of the technology in its manufacture do not allow obtaining sheets less than 0.5 mm thick. It is made of high quality carbon or alloy steel. The cost of such sheets is lower than that of cold rolled sheets.
- Cold rolled - features high surface quality and dimensional accuracy as requested by the customer. The method of rolling (cold) carbon steel is used.
Also, metal sheets are subdivided into smooth and corrugated, painted or galvanized, perforated, expanded metal.
For convenience and distinction of sheet characteristics, the marking method is used:
- Edged edge "O", Uncut edge "BUT".
- Rolling accuracy "A" - increased, "H" - normal.
- Flatness "PN" - normal, "PV" - high, "PO" - especially high, "PU" - improved.
Sheet metal products are one of the most popular and versatile. It is highly durable, does not require special storage conditions and is easy to transport, easy to handle and affordable.
I-beam
Also, a product - an I-beam metal, which has the shape of the letter "H" in section, has won its popularity and demand among steel rolled products. This sectional model gives special strength and rigidity, much higher than that of a corner or channel, thanks to which it takes on large loads. It is mainly used for partitions in construction.
I-beam types.
Divided into 2 types:
- Hot Rolled - Produced from billet steel by rolling (hot). The absence of seams and solidity makes it more durable and does not require additional processing. Among the disadvantages are the limited size and very thick walls, which increases the weight of the beam.
- Welded - made by welding hot rolled metal sheet. When the wall and two flanges of the beam are welded. �
