Description<\/h2>\n

BOMIS Steel supplies premium S250GD+Z275 hot-dip galvanized structural steel, engineered to meet stringent international standards. Here is what the grade designation means for your specific application: 1mm Aluminium Sheet<\/p>\n

S (Structural): Indicates that the steel is classified for structural applications, offering reliable load-bearing capabilities.<\/p>\n

250 (Yield Strength): Guarantees a minimum yield strength of 250 MPa, ensuring the substrate provides robust mechanical performance.<\/p>\n

GD (Hot-Dip Galvanized): Signifies the specialized hot-dip galvanizing process used to bond the protective coating to the steel substrate.<\/p>\n

Z275 (Coating Weight): Represents a heavy, pure zinc coating with a total mass of 275g\/m\u00b2 (double-sided).<\/p>\n

Need higher strength with the same Z275 coating? Our S350GD+Z275 Acier HDG<\/a> delivers 350 MPa minimum yield \u2014 a 40% strength increase over S250GD \u2014 for structural applications where load capacity drives material choice.<\/p>\n

      FAQ<\/h2>\n

      Q1: What is the main difference between S250GD and standard DX51D galvanized steel?<\/p>\n

      A: The primary difference lies in the mechanical properties. While DX51D is a commercial quality steel used for basic bending and forming, S250GD is a structural grade. It guarantees a minimum yield strength of 250 MPa, making it suitable for load-bearing applications like construction purlins and solar mounting brackets where structural integrity is critical.<\/p>\n

      Q2: Is a Z275 zinc coating sufficient for high-humidity or tropical climates?<\/p>\n

      A: Yes. The Z275 designation means a heavy coating of 275g\/m\u00b2 (double-sided). This thick layer of pure zinc provides exceptional corrosion resistance. It is highly recommended for outdoor applications, particularly in regions experiencing intense monsoon seasons or elevated humidity, ensuring a prolonged service life.<\/p>\n

      Q3: Can BOMIS Steel provide custom widths and lengths for S250GD coils?<\/p>\n

      A: Absolutely. While our standard widths range from 600mm to 1500mm, we operate advanced in-house processing lines. We offer custom slitting, cut-to-length services, and profiling to meet your exact manufacturing specifications, minimizing your material waste.<\/p>\n

      Q4: What is the Minimum Order Quantity (MOQ) and typical lead time for this grade?<\/p>\n

      A: Our standard MOQ for S250GD+Z275 is 10 Metric Tons. Depending on the specific dimensions and whether custom processing is required, our standard production and delivery lead time is typically between 15 to 30 days. Contact our sales team for an exact timeline based on your project schedule.<\/p>","protected":false},"excerpt":{"rendered":"
