10% TO 15% SAVING OF MATERIALS BY USING H-BEAM

图片
10% TO 15% SAVING OF MATERIALS BY USING H-BEAM   H-beam steel  is an economical section steel with more optimized section area distribution and more reasonable strength-to-weight ratio. Nowadays, H-beam steels have been widely used in today's steel structure construction. Compared with its competitor I-beam steel, H-beam steel profile has many advantages, among which the most significant one is its mechanical properties per unit weight. This allows construction side to cut costs and speed up building process. So how do H-beams steels do this? To the naked eye, the H-beam and I-beam steels have a similar appearance. But the differences in flange and two outside beams give H-beam steel a great performance advantage. On the one hand,There is no inclination in the inner surface of H-beam steel. Its upper and lower surfaces are parallel, and the inner edge has uniform thickness. Those characteristics bring better torsion resistance for H-beam steel, as well as the reas...

PVD COATING FOR COLORED STAINLESS STEEL SHEETS

What is PVD coating ? PVD stands for Physical Vapor Deposition. PVD Coating refers to a variety of thin film deposition techniques where a solid material is vaporized in a vacuum environment and deposited on substrates as a pure material or alloy composition coating. PVD coatings surpass traditional electroplated coatings, it's more corrosion resistant and have superior hardness. The process of PVD coating During the process, first of all the stainless steel is cleaned to make sure that the coating will bond well. The steel is then placed in a vacuum chamber with a “target” metal; this will be used to create the coating. A high vacuum level is needed in the coating chamber, then a small amount of argon gas is introduced. A high voltage circuit is used in order for the stainless steel and target to bond or adhere. This allows the argon ions to bombard the target to release atoms of the target metal, which are deposited on the stainless steel substrate as the coating. This PVD p...

SPOT NICKEL PREMIUM TO NARROW IN THE NEAR FURTHER

SPOT NICKEL PREMIUM TO NARROW IN THE NEAR FURTHER     Nickel is the essential allying element in the 300 series  stainless steel grades . The presence of nickel results in the formation of an “austenitic” structure that gives these grades their strength, ductility and toughness, even at cryogenic temperatures. It also makes the material non-magnetic. While the role of nickel has no direct influence on the development of the “passive” surface layer, it results in significant improvement in resistance to acid attack, particularly with sulfuric acid. So that the price of nickel affected the price of stainless steel.   Nickel price continued to trend high. Spot nickel premium is likely to narrow further and some market participants are likely to remain on the sidelines. Nickel on the LME ended the weekend in a volatile session following copper after a first-phase trade deal between China and the US dispelled concerns about the health of the global economy...

WHY SHOULD USE COLORED STAINLESS STEEL SHEETS INSTEAD OF TRADITIONAL PREPAINTED STEEL COIL

图片
Many people may confound  colored stainless steel sheets  with traditional prepainted steel coil or just don’t know which one to choose. A miss is as good as a mile, especially in the building materials industry. Tiny differences in raw materials and manufacturing technique can make a huge difference in the properties of products. As long as the budget is adequate, you should always choose colored stainless steel sheets. Here are the advantages of it when compares to traditional prepainted steel coil: 1.Better Corrosion Resistance and Weather Resistance Good corrosion resistance of colored stainless steel sheet is derived from its high quality zinc galvanized or Al-Zn galvanized aluminum basal plate. This kind of basal plate is different from the cold-rolled steel sheet which used as the basal plate of traditional prepainted steel coil. Colored stainless steel sheet has better resistance to the corrosion of acid, alkaline and other contaminants because of the prot...
