PRODUCT CENTER
410 is a basic general-purpose martensitic stainless steel, used for high-stress parts, with good corrosion resistance and high strength and hardness. The alloy 410 contains at least 11.5 percent chromium, which is just enough to exhibit corrosion resistance in mild atmospheres, vapors, and many mild chemical environments.
Q195 galvanized sheet is a surface galvanized sheet with yield strength of 195MPa.
420 is a hardenable martensitic stainless steel that contains at least 12% chromium, just enough to provide corrosion resistance. It has good ductility in the annealed condition, but can be hardened to a minimum Rockwell hardness of 50 HRC, which is the highest hardness in the 12% chromium scale. Due to its hardening properties, 420 are not often welded, although this is possible.
DX51D (European Standard EN 10346) and SGCC (Japanese Standard JIS G3302) are two widely used international standards that specify commercial-grade hot-dip galvanized steel sheets. This product is manufactured by processing a low-carbon steel substrate through a continuous hot-dip galvanizing process, resulting in a steel product coated with a pure zinc layer. It is primarily intended for forming applications rather than structural load-bearing purposes.
Galvanized sheet G550 belongs to high-strength series galvanized sheet, with high requirements for tensile strength and yield strength. Its minimum yield strength is 560Mpa, minimum tensile strength is 650Mpa, and zinc layer thickness is 275g/m2. It has strong corrosion resistance and is mainly used for building structures with high strength requirements, such as Z-shaped steel, C-shaped steel, floor bearing plate, etc.
DX52D (European Standard EN 10346) and SGCD1 (Japanese Standard JIS G3302) are specifications for hot-dip galvanized steel sheets designed for deep drawing and complex forming applications. They feature a low-carbon steel substrate with enhanced formability, coated with a pure zinc layer for corrosion protection. The "D" in both designations signifies their primary use for forming (Drawing).
Q235 galvanized sheet is a surface galvanized sheet with yield strength of 235MPa.
Galvalumed sheet, with 55% aluminum zinc alloy coating on the surface. The surface of the Galvalumed sheet presents a unique smooth, flat and gorgeous star, and the basic color is silver white. The special coating structure makes it have excellent corrosion resistance. The normal service life of the Galvalumed sheet can reach 25a, and the heat resistance is very good, which can be used in the high temperature environment of 315 ℃; The coating has good adhesion with the paint film, has good processing performance, and can be punched, sheared, welded, etc; The surface conductivity is very good.
Hot-dip galvanized C-channel steel is a versatile structural component prized for its combination of strength, form factor, and superior corrosion resistance. The hot-dip galvanizing process creates a metallurgically bonded zinc coating that provides robust, long-lasting protection against rust in demanding environments. This makes it an ideal, cost-effective choice for frameworks, supports, and edging where durability and reduced maintenance are critical.
