Features and Advantages of Grinding Steel Bar Concentrating on wear-resistant grinding material for 30 years, Shandong Huamin Steel Ball Joint-Stock Co., Ltd is one of the largest grinding rod manufacture in China. We manufacture the product with the length of 2m to 7m and the diameter of 40mm to 140mm. The data is just for reference. The product can also be customized. After years of research and development, we finally develop the new-type steel grinding rod successfully. The newly developed product is characterized by low wear, unique chemical composition, high hardness of 45HRC to 55HRC, and strong toughness. Meanwhile, via the quenching and high temperature tempering treatment, the internal stress is removed. The product has good straightness, and won't break, bend and come out with two tapering ends. The economic benefit is much in evidence. a. The blanking of the steel grindng bar is implemented via the sawing machine. The dimensional tolerance would adide by the requirements of the order. After the implementation of blanking, the two ends of the raw material are polished into the R arc via the polishing machine. b. The surface of the product for the rod mill cannot have the crack, overburning and fissure visible to the naked eyes. c. The nonstraightness of the product is less than 0.2%. The diameter tolerance ranges from +0mm to -1.5mm. The length tolerance is fro +0mm-25mm. The fracture should be less than 3%.

Steel I-Beams, also known as H-Beam, are one of the most common steel profile used in construction and civil engineering. It provide support for buildings and load-bearing walls. The I-shaped section optimises strength weight ratio & surface usability to provide a highly efficient product. It is right-angle formed & so has high bending resistance, construction application simplicity. It save cost, is light weight and thus is used widely in various industries.
A T-Beam is a load-bearing structure with a t-shaped cross section. The top of the t-shaped cross section serves as a flange or compression member in resisting compressive stresses. The web of the beam below the compression flange serves to resist shear stress and to provide greater separation for the coupled forces of bending. Other uses for one way to make a T-beam to be more efficient structurally is to use an inverted T-beam with a floor slab or bridge deck joining the tops of the beams. Done properly, the slab acts as the compression flange.
Angle steel bars are perpendicular elongated steel bars connected together as a wave-like product. There are equal angles and unequal angles. Angle steel bar is a simple sectioned carbon structural steel mostly used in metal products fabrication and construction of workshop. In application, it must has weldability, plasticity deformation performance and high mechanical strength. The raw material to produce angle steel is low-carbon billet. Finished product of angle steel is hot roll formed.
Channel bar, also known as C-Beam, are often used where the flat, back side of the web can be mounted to another flat surface for maximum contact area. The shape provides superior structural support, making it an ideal product for frames and braces used for machinery, enclosure, vehicle, building and structural support applications. They are also sometimes welded together back-to-back to form a non-standard I-beam.
Round steel bar is a round-shaped solid steel bar. It is hot formed, forged or cold formed. The specification of hot formed round steel is 5.5-250mm. The small round steel are normally distributed in bundles of 5.5-25mm, and is normally use to make steel bar, bolt and all kinds of mechanical parts. Round steel greater than 25mm are mainly use to make mechanical parts or seamless steel tube ring.
Square Bars are made from very high quality raw material which ensures high durability at its user end. These steel square bar are widely finds its applications in various industrial and commercial sectors.
Steel rebar, also known as deformed bar, is a steel bar or mesh of steel wires used as a tension device in reinforced concrete and reinforced structures to strengthen and hold the concrete in tension. Rebar surface is often patterned to form a better bond with the concrete.
