JFE鋼板 List of Products and Services

Introducing JFE Steel's metal roofs and the "Disaster-Resistant Package" with system steel frames. Not only is high durability a given, but the lightweight metal roofs and compact high seismic resistance system steel frames provide safety and reliability against earthquakes and fires, and they can be easily adapted to narrow land. Additionally, the metal roofs use perforated steel sheets with a 25-year warranty. Combined with the standard specification "Frame Kit," which boasts a durability of 90 years across three generations, you can use them with peace of mind for a long time. 【Features】 ■ High seismic resistance ■ High durability ■ Rain and fire protection ■ Suitable for narrow land *For more details, please download the PDF or feel free to contact us.

The "Frame Kit" is a system steel frame that provides a set of "steel members," "various manuals," "dedicated input software," and "structural calculations and structural drawings." We conduct measurements of various material strengths, checks of joint strength and rigidity, and full-scale brace panel (shear wall) load tests to supply safe and reliable steel-framed buildings. The input system "AI-FRAME" calculates the ideal framework that balances floor planning and framework. It performs safe and secure structural design through a structural analysis program. 【Features】 ■ Compact foundations due to lightweight members ■ Short construction period and easy installation save construction costs ■ Steel frame precutting eliminates the need for welding work ■ Use of ALC panels provides superior sound insulation compared to wooden structures ■ Combined with external insulation for energy-saving measures *For more details, please download the PDF or feel free to contact us.

"Gulf Flex" is a specification that softens the plating layer of painted molten 55% aluminum-zinc alloy coated steel sheets (Color GL) by applying proprietary technology, thereby enhancing workability. Currently, the widely used Color GL has a hard plating layer, which can lead to cracks on the surface during bending processes, resulting in rust formation. This technology was developed to address that issue. Thanks to the unique technology, it offers excellent quality performance that improves the durability of the processed parts. [Key Points] - Improved workability - Enhanced corrosion resistance *For more details, please download the PDF or feel free to contact us.*

The "J Craft Series" is a color-coated steel sheet that does not contain any environmentally harmful substances, such as chromate (hexavalent chromium), and is designed with environmental considerations in mind. As an alternative to chromate-based rust prevention technology, we have developed chromate-free rust prevention technology that incorporates self-repairing functions for corrosion protection, suppression of corrosion reactions through the formation of stable by-products, enhancement of barrier properties against corrosion factors, and improved adhesion to the substrate. In addition to environmental functionality, aesthetics, and new standard colors, our unique coating technology provides durability, and we have achieved chromate-free products across our entire lineup, contributing to your SDGs initiatives. 【Lineup (partial)】 ■ Kiwami - Fluorine GL ■ Kiwami - MEGA ■ Kiwami - MAX *For more details, please download the PDF or feel free to contact us.

"JFE EcoGal" is a galvanized steel sheet that improves corrosion resistance and aging discoloration by adding trace amounts of magnesium (Mg) and nickel (Ni) to a molten zinc-5% aluminum alloy coating (commonly known as Galfan), complying with JIS G 3317 standards. By using a small amount of magnesium (Mg), it achieves weldability and softness of the coating layer equivalent to molten zinc coating (GI) and conventional Galfan (GF). It has a high zinc content with sacrificial corrosion resistance, maintaining excellent corrosion resistance at the cut edges. 【Features】 ■ Corrosion resistance of flat surfaces ■ Corrosion resistance of processed areas ■ Corrosion resistance of cut surfaces ■ Alkali resistance *For more details, please download the PDF or feel free to contact us.
