Q:How to distinguish cold formed section steel and hot rolled section steel?

Hot rolled steel is a kind of steel with various geometrical cross section formed by heating billet. According to the different angles can be divided into flat steel, steel section, steel and I-shaped steel and hot-rolled L steel; steel according to the different section shape, divided into simple and complex section or section section and section three steel cycle:The characteristics of the simple section are the cross section, any point on the periphery as a tangent, generally not cross section, such as round steel, square steel, six angle steel, flat steel, triangular steel, arch steel and elliptical steel.Complex sections include angle steel, I-beam, channel steel, T steel, H steel, Z steel, rail, steel plate pile, window frame steel and other miscellaneous section steel;The periodic section shape and dimension along the length direction of the steel section changing periodically, such as rebar, axle and steel ploughshare.

Q:What is special steel?

Quality profilesHigh quality profiles is made of high quality steel processing profiles. Hot rolling (forging) quality profile, cold drawn (DIAL) quality profile and other varieties. Hot rolled (forging) quality profiles including carbon structural steel, carbon tool steel, alloy structural steel, spring steel, stainless steel, bearing steel, alloy tool steel, die steel, high-speed tool steel and other varieties. The cold (DIAL) quality profiles including carbon structural steel, carbon tool steel, alloy structural steel, spring steel, stainless steel, bearing steel, alloy tool steel, high-speed tool steel, free cutting steel, cold heading steel, S/5A and other varieties of.S/5A is a product used to make bombs, bullets.

Q:What does "BH" mean?

Section steel is a strip steel with definite section shape and size. It is one of the four big kinds of steel (plate, tube, mould, wire). According to the section shape, the section steel is divided into simple section steel and complex section steel (deformed steel). The former refers to the steel, round steel, flat steel, angle steel, six angle steel; the latter refers to the I-beam, channel steel, steel, steel, steel frame bending etc..

Q:What does "M" mean?

Section steel is a strip steel with definite section shape and size. It is one of the four big kinds of steel (plate, tube, mould, wire). According to the section shape, the section steel is divided into simple section steel and complex section steel (deformed steel).

Q:Does the profile include H?

Profiles include section H steelThe online quote H steel and profiles in the angle of groove separate quotation, mainly because H steel has great use compared with the other, and the demand is relatively more, but in some cases, and H type steel I-beam can also substitute for each other.

Q:Elastic modulus of section steel

The elastic modulus of steel is 2.1 * 10^7N/cm L.

Q:Can the section steel butt joint in the end?

Shape steel can butt joint, but pay attention to the quality of welding.Because of the lack of groove, it is impossible to use common arc welding. Recommended laser welding (if required for high strength). The quality of welding can be referred to the GB of welding.

Q:What are the common types of profiled steel?

Section steel is divided into two types: simple section steel and complex section steel.Simple section steel: steel, wire rod, square steel, flat steel, six angle steel, triangular, elliptical steel, steel arch steel, etc..

Q:What kind of steel is used in steel columns?

Compared with other steel piles, steel pipe piles have their own advantages in many aspects, such as long joint welding, single pile bearing capacity, bending rigidity and penetration ability.
