How much does rolled steel sort know, by section cent? By appearance cent?

Rolled steel classification: The sort of commodity of rolling rolled steel a lot of, press the section appearance classification of rolling commodity:

Profiled bar
Profiled bar is phyletic in rolled steel most. The section of every kinds of appearance has again a lot of different measure standard. By its section appearance can be divided again for brief section and mixed and disorderly section two kinds big.
1, brief section profile
Following plan institute are shown. The steel of in the right way that brief section sees more, round steel, flat steel:

Sketch map of all sorts of section cross section (brief section)
Fang Gang: Its standard makes clear with measure growing by the side of its. Grow by the side of Fang Gang normally for 5~250mm.
Round steel: Its standard makes clear with its diameter measure. Normally round steel diameter is 5~200mm. Meantime diameter is the round steel of 5~9mm, become dish of delivery, friend says wire rod. Because of section small, length is big, also weigh wire.
Flat steel: The product with its section width and ply demonstrates its standard. Width is 12~200mm, ply is, 4~60mm.
Angle iron: Have the branch of equilateral and not equilateral angle iron, every side leg grows equilateral angle iron 20~250mm, call No.2~ No.25 angle iron accordingly. Grow by the side of the both sides of not equilateral angle iron for 25/16~250/160mm, call No.2.5/1.6~ No.25/16 accordingly not equilateral angle iron.
In addition, there still are three angle irons, 6 angle irons and bend profiled bar to wait in brief section section a variety of.

2, profile of mixed and disorderly section
Following plan institute are shown. See more have:

Sketch map of all sorts of section cross section (mixed and disorderly section)
I-steel: Have the branch of normative I-steel, light-duty I-steel and wide leg I-steel. Lumbar height is normative I-steel 100~600mm, call No.10~ No.60 I-steel accordingly. Inside of normative I-steel limit has the rake of 14% . Lumbar height is light-duty I-steel 100~320mm, call No.10~ No.32 light-duty I-steel accordingly. Lumbar height is wide leg I-steel 80~1200mm, call No.8~ No.120 wide leg I-steel accordingly. Because the both sides of limit the outside and the inside of wide leg I-steel is mutual parallel, also call H profiled bar.
Channel: The waist of normative channel is 50~450mm high, call No.5~ No.45 channel accordingly. The limit inside rake of normative channel is 9% .
Rail: Of all kinds rail all makes clear its normative large and small with the heft of every meters of length. 7~24gk/m uses track for mine, 38~75gk/m uses heavy track for railroad, 80~120gk/m uses crane track for crane.
In addition, profile of mixed and disorderly section sees more still sheet pile of Z word steel, T word steel, steel, heavy course is received board, window frame steel. Especially little profiled bar, lin Lin the profile of appearance of total total section is more, did not list one by one here.

Armor plate
Armor plate can be divided by ply for thick board, thin plate and foil 3 kinds big.
Thick board: Ply is 4~160mm above, width is 600 above (the widest can amount to 5500mm) armor plate.
Laminose: Ply is the armor plate of 0.2~4.0mm.
Foil: Ply is less than the armor plate under 0.2 Mm. Most Bao Keda 0.02mm.

Steel tube
The rolled steel that shuts section hollowly calls steel tube. The figure of steel tube section that sees at most is a circle normally. But also have a lot of planting the different with section very mixed and disorderly appearance steel tube, following plan institute are shown. By production method can be divided for seamless steel tube and have seam steel tube (say to solder again steel tube) two kinds big.
