Q235 Hot - Rolled Cold - Rolled H - Type Steel I - Beam H section steel is a new type of economic construction steel. Economic and reasonable h-beam section shape, good mechanical performance, rolling section on each extension point is relatively uniform, small internal stress, compared with ordinary beams, with large section modulus, light weight, save metals etc..
HW, HM, HN, H are the general names for H-beam steel. H-beam steel is welded while HW, HM, HN are hot rolled. ⑫. HW refers to H-beam steel which basically has the same height and flange width, mainly used for steel core column in reinforced concrete frame column, also known as stiff steel column.
Universal H Beams, H Beams, I-Beam manufacturer / supplier in China, offering Q235 Hot - Rolled Cold - Rolled H - Type Steel I - Beam, Basalt Mechanism Rock Wool Board Hydrophobic Fire - Resistant Rock Wool Board, Annual Production of 15 Million Square Meters of Gypsum Board Production Line (heat source steam) and so on.
Hot rolled steel has been roll-pressed at high temperatures (over 1,700Ë F), which is above the re-crystallization temperature for most steels. This makes the steel easier to form, and also

Hot rolled end temperature is 800 ~ 900 ℃, generally cooling in the air, so hot rolling state is equivalent to normalizing treatment. Most of the steel is rolled in hot rolled. Due to the high temperature, the surface of hot rolled steel produces a layer of oxidation sheet, thus has
H beam is a new production for construction and easy to be used with light weight, strong rigidity, high quality and fine appearance, After using h beam,30%-50% construction time can be decreased and 5% usage area of the room can be increased, 10%-30% of steel can be saved and 20% of the integrated cost of construction can be decreased compared with hot rolled sections.
The bundles can be cut to length with a tolerance of +/- ½”. Typical minimum quantities are 3–5 tons for stainless steel and 10–15 tons for carbon steel. The process is particularly suitable for producing small to midsize special geometries. Hot rolled sections are used for general building
Apr 02, 2009 · Differences in hot rolled and cold rolled sheet steel? one thing about hot rolled is the steel mills say it has a .010 tolerance, doesnt sound like much but it can add up, cold rolled usely will be right on the money or maybe .001 tolerance, hot rolled has a difference in hardness between the edges and the center of the sheet, cold rolled

Hot Rolled Sheet Steel is an unprocessed, mill edge coiled product and does not include any processing such as temper rolling, tension leveling, pickling, oiling or side trimming. Hot Rolled products are produced to ASTM Specifications A1011, A659, A635 or A1018.
Steel W type I beams are a kind of hot rolled section steel. They are also known as H sections, universal columns, wide flange beams, or W Q345d Steel Plate, Q345d Steel Plate Suppliers and And whether q345d steel plate is hot rolled, or cold rolled.
H beam is developed and optimized from I beam, a kind of economical profiled steel with a better mechanics capabilities. The web plates and the flanges are in plumb. The inner flange runs parallel to the outer one. Its flanges are very straight and the edges are clear, especially named by the similarity between the section shape and the letter "H".
Hot Rolled, Pickled & Oiled. Hot Rolled Pickled and Oiled – hot rolled coil or sheet steel that has been descaled of oxide film by either a chemical method, mechanical method, or a combination of both and oiled to help retard corrosion during storage and after descaling. "HRPO" is available in various gauges, widths, and cut lengths or coil.
