Tianjin Emerson Metal Steel Products Co., Ltd. is proud to offer S350GD+Z-ZG 4x8 Galvanized Steel Sheet Laser Cutting Bending Welding Fabrication under the EMERSONMETAL brand. As a professional metal fabrication factory equipped with advanced laser cutting, bending, and welding equipment, we specialize in transforming S350GD+Z-ZG galvanized steel sheets into precision-customized parts. Designed to balance strength, corrosion resistance, and workability, our products cater to industries ranging from construction to automotive manufacturing, delivering reliable solutions that meet strict performance and durability standards.
At the core of our offering is S350GD+Z-ZG, a high-strength galvanized steel grade engineered for structural and industrial applications. The “4x8” specification refers to its standard sheet size (4 feet by 8 feet), providing a versatile base for fabrication while allowing for efficient material utilization. What truly sets this steel apart is its hot-dip galvanized coating—a layer of zinc applied during production that acts as a protective barrier against rust and corrosion. This coating ensures the material can withstand exposure to moisture, humidity, and outdoor elements, making it ideal for both indoor and outdoor use.
S350GD+Z-ZG’s mechanical properties are carefully balanced to meet diverse fabrication needs. With a yield strength of ≥350 MPa and tensile strength of ≥420 MPa, it offers sufficient rigidity to bear structural loads, while an elongation rate of ≥16% ensures good ductility—meaning it can be bent, stamped, or formed into complex shapes without cracking. Its chemical composition, featuring controlled levels of carbon (≤0.2%), silicon (≤0.6%), and manganese (≤1.7%), contributes to this balance: low carbon content enhances weldability, while manganese boosts strength, making it a versatile choice for both structural and mechanical parts.
Our fabrication process is designed to maximize the material’s potential. Laser cutting is the foundation of our service, using high-precision CNC laser machines to cut the 4x8 sheets into custom shapes with tolerances as tight as ±0.1mm. This process ensures clean, burr-free edges and minimizes material waste, even for intricate designs. Bending is performed using advanced equipment that applies uniform pressure, preserving the steel’s structural integrity and avoiding damage to the galvanized coating—critical for maintaining corrosion resistance. Welding is executed by skilled technicians using low-heat techniques to prevent zinc oxidation at joint areas, ensuring welded parts retain the same strength and durability as the base material.
Customization is a key focus of our service. We accept OEM orders based on customer drawings, offering flexibility in dimensions, thicknesses, and finishes beyond the standard 4x8 size. Whether you need small-batch prototypes or large-volume production, we accommodate orders starting from 1 piece, ensuring adaptability for projects of all scales. Our quality control process is rigorous: we source S350GD+Z-ZG steel from certified suppliers, verify chemical compositions and mechanical properties upon receipt, and inspect every finished part for dimensional accuracy and coating integrity. This attention to detail guarantees that each product meets the highest industry standards.

Application Scenarios
S350GD+Z-ZG 4x8 galvanized steel sheets, with their balanced properties, find applications across multiple industries, each leveraging their unique strengths:
Construction and Building Materials: The material is widely used in roofing panels, wall cladding, and ventilation ducts. Its galvanized coating resists rain and humidity, ensuring long-term performance in outdoor and indoor environments. For example, roofing panels made from S350GD+Z-ZG maintain their structural integrity even in harsh weather, while their 4x8 size allows for quick installation.
Automotive Manufacturing: In the automotive industry, S350GD+Z-ZG is used to produce body structural parts, chassis brackets, and door frames. Its strength supports vehicle safety, while its formability allows for complex shapes needed in modern car designs. The galvanized coating also protects against road salt and moisture, extending the lifespan of these components.
Steel Structures and Infrastructure: It is a preferred material for steel frames, fences, and support structures in industrial facilities, warehouses, and public spaces. Fences made from S350GD+Z-ZG resist corrosion from outdoor exposure, while steel frames benefit from its strength-to-weight ratio, reducing overall structural weight without compromising stability.
Mechanical Equipment and Furniture: The material is used in manufacturing machine guards, support brackets, and furniture frames. Its weldability allows for easy assembly of mechanical parts, while its smooth surface (enhanced by the galvanized coating) makes it suitable for furniture that requires both durability and a clean appearance.
Industrial Accessories: S350GD+Z-ZG is used to make connectors, guards, and storage racks. These parts need to withstand regular use and potential impacts, and the material’s combination of strength and ductility ensures they remain functional over time.
Frequently Asked Questions (FAQ)
What advantages does the 4x8 sheet size offer for fabrication? The 4x8 (4 feet x 8 feet) standard size is widely recognized in the industry for its versatility and efficiency. It allows for minimal material waste when cutting common part sizes, reduces handling time during fabrication, and simplifies transportation and storage. For larger projects, this size enables batch processing, lowering production costs. If your design requires smaller or non-standard dimensions, our laser cutting service can easily trim the 4x8 sheets to your exact specifications.
How does the galvanized coating of S350GD+Z-ZG perform in highly corrosive environments, such as coastal areas? The hot-dip galvanized coating of S350GD+Z-ZG provides excellent corrosion resistance in most environments, including coastal areas with salt spray. The zinc coating acts as a sacrificial layer, corroding slowly to protect the underlying steel. For extremely harsh coastal conditions, we recommend specifying a thicker galvanized coating (available upon request) or adding a post-fabrication paint layer to further enhance protection. Our technical team can assess your environment and suggest the best solution.
Can S350GD+Z-ZG be welded, and will welding damage its corrosion resistance? Yes, S350GD+Z-ZG is weldable, thanks to its low carbon content. Our welding technicians use low-heat techniques (such as gas metal arc welding) to minimize damage to the galvanized coating. While the heat-affected zone near welds may temporarily reduce zinc protection, we offer optional post-weld treatments—such as zinc-rich paint or cold galvanizing spray—to restore corrosion resistance. This ensures welded joints remain as durable as the rest of the part.
What is the lead time for custom fabrication orders? Lead time depends on the complexity of the design and order quantity. For simple laser-cut parts (e.g., flat panels with basic shapes) in quantities of 1-50 pieces, we can deliver within 3-5 working days. For parts requiring bending, welding, or larger quantities (100+ pieces), lead times typically range from 7-10 working days. We prioritize urgent orders and can arrange expedited production for an additional fee, with some small-batch orders available in 2-3 working days.
Do you provide material certification for S350GD+Z-ZG? Yes, we supply comprehensive material certification for all orders. This includes chemical composition reports (verifying carbon, silicon, and manganese levels), mechanical property test results (tensile strength, yield strength, elongation), and galvanized coating thickness certificates. These documents confirm that the material meets industry standards and can be provided upon request to support your quality assurance processes.
