![Hat-shaped Steel]( "Hat-shaped Steel")
Hat-shaped SteelHat Shape Steel Profile, also known as outer flange U-steel, is made of cold-formed steel plates with a hat-shaped cross section connected by bolts. The flanges on both sides of the hat-shaped beam are turned up, which not only enhances its load-bearing capacity but also increases the contact surface with the formwork and panel, effectively reducing the number of J-shaped greenhouse skeletons required.Learn More →![Hat-shaped Steel]( "Hat-shaped Steel")

Galvanized Steel StripGalvanized steel strip refers to a steel product in which a layer of zinc or other metal (such as aluminum) is coated on the surface of a long steel plate that has been cold-rolled or hot-rolled. The substrate can be hot-rolled strip steel or cold-rolled strip steel, and a zinc layer or zinc alloy layer is formed on the metal surface through galvanizing process, thereby significantly improving the corrosion resistance and service life of the steel.Learn More →![C-Shaped Steel]( "C-Shaped Steel")
C-Shaped SteelC-shaped steel is a cold-formed steel with a cross-section resembling the letter "C," typically manufactured from hot-rolled or cold-rolled steel plates through a continuous cold bending process.

![Channel steel & C-shaped steel]( "Channel steel & C-shaped steel")
Channel steel & C-shaped steel2025.12.19Appearance difference (difference in cross-sectional shape): Channel steel is produced through hot rolling and directly shipped as finished products by steel mills. Its cross-section is "U"-shaped, with parallel flanges on both sides and a web extending up and down in the middle. C-shaped steel is made from hot-rolled coils through cold bending, featuring thin walls, light self-weight, excellent sectional performance, and high strength. In simple terms, the appearance is as follows: straight-edged is channel steel, and curly-edged is C-shaped steel![The world of steel coils holds endless mysteries | Exploring the mysterious world of galvanized steel sheets]( "The world of steel coils holds endless mysteries | Exploring the mysterious world of galvanized steel sheets")
The world of steel coils holds endless mysteries | Exploring the mysterious world of galvanized steel sheets2025.12.19In recent years, galvanized steel sheets have become highly representative metal materials in modern architecture and home appliances due to their excellent protective efficacy and long service life. Let's explore the mystery behind this.![Why is Z-shaped steel purlin preferred for roofs?]( "Why is Z-shaped steel purlin preferred for roofs?")
Why is Z-shaped steel purlin preferred for roofs?2025.12.19In coastal areas with frequent typhoons, about 60% of roof collapse accidents are directly related to the failure of purlin systems. Z-shaped steel, with its unique cross-sectional design and mechanical properties, has gradually become the "invisible guardian" of wind resistant roof systems.
