What is spring steel? Spring steel is, as its name implies, perfect for springs. Because springs are made to be pushed and flexed, a metal with lower yield strength loses shape and ceases to function as a spring. Spring steel is also commonly used for prop swords, lockp...

Oxidation occurs on steel as a result of the steel interacting with oxygen. It can cause pitting and a general dulling and discoloration of the finish. The oxidation not only makes the steel visually unappealing but if left unchecked, it can compromise the integrity of the steel. Oxidized steel is cleaned by using the right materials and implementing a straight-forward procedure. The desired resul...

It is he heat treatment process by which steel products are reheated to a suitable temperature in order to remove stresses from previous processing and to soften them and/or improve their machine ability and cold forming properties.

galvanized steel is produced when hot or cold rolled sheet or strip is coated with zinc, either by the hot-dipping or electrolytic deposition processes. Zinc coating applied by the hot dip method is normally heavy enough to resist corrosion without additional protective coating. Materials electronically galvanised are not used for corrosion-resistant applications without subsequent chemical treatm...

Galvalume was invented by Bethlehem Steel in 1972. It is a trademarked name, but many people use it as a generic term to describe a metal roofing product consisting of steel coil coated with a metal alloy. That alloy is 45% zinc and 55% aluminum and looks similar to galvanized steel, but the visible crystals are smaller and close together, giving it a smoother appearance. Galvalume has a cousin,...

Steel has changed our world like no other substance. New high performance steel allows a jet pilot to reach new heights…a surgeon to perform a delicate operation. It is the solid rocket booster casings that allow shuttle astronauts to explore new frontiers…and the roller coaster ridden by a child. Each piece of steel we make is engineered to fit precise specifications. It is an industry where prod...

Foreign government subsidies and other market-distorting policies in the steel sector have resulted in massive global steel overcapacity – estimated by the OECD at more than 700 million metric tons, over seven times U.S. raw steel production. This overcapacity, combined with sluggish world demand and import barriers in other markets, has resulted in significant levels of steel imports entering int...

For normal Galvalume coil , the coating chemical composition is 55% aluminum, 43% zinc, and 1.6% silicon ， with high corrosion resistance. But the price is also higher.2. PPGL base plate galvalume coil For this kind , the aluminum content is just about 20 to 30%. So...

Both GALVALUME and galvanized sheet steels are made by a "continuous hot dip" process. Coils of cold rolled steel are welded end-to-end and processed continuously on the coating line at speeds up to 600 feet per minute. The uncoiled sheet is first cleaned to remove rolling oils and mill dirt, and to reduce surface oxides so that the surface will accept the coating. These continuous sheets are firs...
