Beijing Weihong booming sales agent company rebar manufacturers, including Tangshan Steel, Xuanhua Steel and Chengde Steel, dedication, 2672, note :( Laiwu Steel, Jinan Iron and Steel large number of vehicles shipped separately scheduling and prices favorably); Material including HRB400 three rebar, HRB400E three seismic rebar, HRB500 four rebar, HRB400, HRB400E plate, screw, HPB235, HPB300 high line (wire, rod, plate round). Reinforced concrete with reinforced concrete refers to straight bars or reinforced with strips of steel plate, its shape into round bar and deformed bar two, the delivery status for round two straight bar and plate. Round bar is actually an ordinary low-carbon steel plate small round and round. Deformed steel reinforced ribbed surface, usually with two longitudinal ribs and evenly distributed along the length of the transverse ribs. Lateral rib shape helical, herringbone, crescent-shaped three kinds. With a nominal diameter of a few millimeters. Deformed bars nominal diameter is equivalent to the cross section such as round bar nominal diameter. Reinforcement of 8-50 mm nominal diameter is recommended 8,12,16,20,25,32 mm diameter. The main reinforcement in concrete tensile stress. Since the role of the ribs of the deformed bar and concrete have a greater binding capacity, which can better withstand external forces. Steel is widely used in a variety of building structures, especially for large, heavy, light and thin-walled high-rise building structures. When buying rebar, the first from the appearance of size, the cursor can be used to measure the actual size of the card is a simple measuring tool than indicated size (both have size marks on the general roll rebar) about a size or so smaller or more (such as the inner diameter of 12mm rebar standards was 11.5 ± 0.4mm, but mostly about shoddy steel inner diameter 10mm). At the same time, some shoddy flat rolled steel by way of deceptive vision, thus observed for flat steel oval from the end face, and the face should be a regular member is substantially circular; Second, look at the quality of the surface, due to shoddy rebar with adobe rolling, the surface of poor quality, often with scarring and other defects, have an overall roughness. At the same time, some small rolling mill due to the heating temperature, rolling speed is not enough, the surface reddish color; Third, regular steel manufacturers in the factory when most large bundle package bundles are hung on the steel and the corresponding physical metal signs, indicating manufacturers steel grades, batch number, specifications and test code and so on. And shoddy steel production due to poor condition, no heavy lifting equipment, mostly small bundle (about ten bundled) packaged or in bulk, metal signs, no quality assurance. Of course, to simply avoid buying inferior steel, or to direct the agent to purchase brand-name manufacturers, especially in the province famous brand reinforcement (for the three steel "Min" brand rebar) is not only stable quality, but also easy to handle, even if a dispute arises . Experienced people can also spark distinguish other chemical ingredients.
