Optimized Mechanical Properties
Q235B Base Steel: A low-carbon steel with a minimum yield strength of 235 MPa, offering good ductility, weldability, and formability. Ideal for general structural applications requiring moderate strength, such as frames, brackets, and non-critical load-bearing components.
Q355B Base Steel: A higher-strength low-alloy (HSLA) steel with a minimum yield strength of 355 MPa, providing superior tensile strength and impact resistance (especially at low temperatures). Suitable for heavy-duty structural uses like bridges, machinery, and high-load components.
Formability: Both grades retain their ability to be cut, bent, welded, or machined after galvanizing, allowing for versatile fabrication into complex shapes without compromising structural integrity.
Enhanced Corrosion Resistance
Dual Protection Mechanism: The zinc coating acts as a physical barrier against moisture, oxygen, and corrosive agents (e.g., salt, chemicals), while also providing cathodic protection—zinc corrodes preferentially to steel, shielding the base metal even if the coating is scratched.
Adaptability to Environments: Performs well in outdoor, industrial, and moderately humid settings. Hot-dip galvanized versions (thicker coatings) excel in harsher conditions (e.g., coastal areas with salt spray), while electro-galvanized options suit indoor or milder outdoor uses.
Long-Term Durability: Extends the service life of the steel by 3–5 times compared to uncoated Q235B/Q355B, reducing maintenance and replacement costs.
Cost-Effective Performance
Balanced Strength vs. Cost: Q235B offers an economical solution for low-to-medium strength requirements, while Q355B provides higher strength at a competitive price point compared to alloy steels. Galvanizing adds minimal cost relative to the extended lifespan and reduced upkeep.
Lifecycle Efficiency: The combination of durable base steel and corrosion-resistant coating minimizes downtime and repair needs, making these plates cost-effective for long-term projects.
Versatile Coating Options
Hot-Dip Galvanizing: Creates a thick (typically 60–100 μm), metallurgically bonded zinc-iron alloy coating, ideal for heavy-duty applications needing maximum corrosion resistance (e.g., construction, infrastructure).
Electro-Galvanizing: Produces a thinner (5–20 μm), uniform zinc layer with a smooth finish, suitable for indoor uses, decorative parts, or components requiring precise dimensions.
Customizable Coating Thickness: Available with varying zinc weights to meet specific corrosion resistance needs, from light-duty (indoor) to heavy-duty (outdoor/industrial).
