Cold-rolled steel (CRS) is a type of steel processed at room temperature, giving it a smooth surface, high strength, and precise dimensions. Its qualities make it ideal for small components used in homes, offices, and light industry. Here’s a look at some common applications: Door and Window Hardware Cold-rolled steel is widely used in household…

Steel coil slitting converts master coils into accurately sized strips for roll forming, stamping, tube making, and other downstream processes. As a wholesale steel supplier, Weijunli Steel is glad to explain the full slitting sequence as it runs on modern lines, highlight critical technical parameters, and give actionable recommendations procurement and engineering teams can use…

The finest cold-rolled steel can directly affect product quality, manufacturing yield of specific products, and total cost of ownership. For business-end buyers and engineers, matching the typical end use with key parameters like thickness and tolerance, mechanical properties, surface finish, and formability is the first thing to consider. Today, Weijunli Steel, a leading steel supplier…

Prepainted steel (also known as PPGI/PPGL or pre-coated metal) is steel that has been continuously coated in a coil coating line at the mill before fabrication. For manufacturers and specifiers, it delivers consistent surface quality, reduces manufacturing steps, and improves lifecycle cost versus field or post-painting. In this blog, Weijunli Steel, a leading steel supplier…

You probably see galvalume steel every day — on rooftops, garage doors, and appliance backs. Its silvery finish keeps buildings cooler and resists rust, quietly protecting structures and products for decades. As a leading steel supplier and processor from China, Weijunli Steel is going to show you more applications of galvalume steel and why it…

Power transformers sit at the heart of electricity transmission and distribution. Their efficiency and reliability directly affect grid losses, operating costs, and asset life. That’s why transformer designers specify grain oriented electrical steel: its directionally optimized magnetic properties deliver far lower core losses and higher flux capability than any practical alternative, making it the industry…

Non-oriented electrical steel (often abbreviated NOES) is a cold-rolled, silicon-alloyed electrical steel engineered to have nearly the same magnetic properties in every in-plane direction. That isotropy makes it the material of choice for rotating machines — motors, generators, and many types of actuators — where the magnetic flux changes direction continuously. As a leading steel…

Steel shapes our modern life today. But for a specific purpose, we need the special one. Today, it is hot rolled pickled and oiled steel to be introduced. This kind of steel is widely used in auto parts, metal shelves and structures, and general manufacturing. As a leading steel supplier and processor, I will introduce…

Steel surface treatment covers mechanical, chemical, electrochemical, and coatings treatments - it aims to finish the steel and protect the steel. Surface treatment has a large effect on the performance characteristics of steel, including corrosion resistance, paint adhesion, wear performance, and even electrical characteristics. Whether you’re specifying structural beams, automotive panels, or precision machine parts,…

From bridges and building structures to fasteners, appliances, and automotive panels, galvanized steel is widely used because the zinc coating slows environmental attack and corrodes preferentially where the substrate is exposed. This blog, delivered by Weijunli Steel, a leading steel supplier and processor, explains how zinc coatings work, compares the main galvanizing methods, outlines performance…
