The difference between wear-resistant plates and ordinary steel plates

Wear-resistant plates (such as Hardox 400/Hardox 450/Hardox 500, JFE-EH400/EH450/EH500) and ordinary steel plates (such as A36, S355JR) both belong to the category of steel, but due to different design orientations, there are significant differences in performance, composition, and application. The specific differences are as follows:

Color steel corrugated sheet

I. Basic Concepts and Structural Characteristics Corrugated panels are formed from metal sheets (such as cold-rolled steel plates, galvanized plates, color-coated plates, etc.) through a rolling process. Among them, color steel corrugated panels (also known as color steel profiled panels) are an important branch. They are specifically made from colored-coated steel plates, galvanized steel plates, etc., through rolling and cold bending, featuring diverse wave shapes and suitable for different application scenarios.

Temperature difference of over 1,000 degrees: Hot rolling and cold rolling

Hot rolling and cold rolling are the two core processes for shaping steel. The fundamental difference between them is not simply "high temperature" versus "normal temperature", but whether they exceed the recrystallization temperature of steel (which ranges from 450℃ to 600℃). This temperature boundary directly determines the internal structure, mechanical properties, and application scenarios of the steel - hot rolling focuses on "rough shaping" and serves as the core for supporting the majority of basic steel production; cold rolling aims for "precision processing" and concentrates on manufacturing steel with high precision and surface quality. Together, they form the "first rough then fine" industrial chain for steel processing.

I-beam steel

In the steel jungle of modern engineering construction, the I-beam steel, with its unique I-shaped cross-section, has become a classic example of balancing mechanical performance and material efficiency. This seemingly simple section of steel, through its precise design for force transmission, has supported countless key structures in fields such as architecture, bridges, and machinery, and can be regarded as a model of "steel usage".

Introduction to Color-Coated Rolls

When it comes to "colored coated sheets", most people would think of it as a cold and impersonal industrial term. But what you don't know is that the refrigerator shells you see first thing in the morning, the steel structure overpasses you pass by on your way to work, and even the courier cabinets at the entrance of your neighborhood, all contain its presence. This material, known as "the high-end customized coat for steel", has quietly permeated every corner of life.
