Tianjin Emerson Metal Steel Products Co., Ltd. is proud to offer SS55 & SS60 Metal Sheet Galvanized Steel Custom Laser Cutting Service under the EMERSONMETAL brand. As a professional laser cutting factory with advanced manufacturing capabilities, we specialize in transforming SS55 and SS60 galvanized steel sheets into precision parts tailored to your exact specifications. Whether for structural components, mechanical parts, or industrial tools, our service combines the superior properties of SS55 and SS60 steel with high-precision laser cutting technology to deliver reliable, durable, and cost-effective solutions.
SS55 and SS60 are two high-performance steel grades known for their distinct mechanical properties, making them ideal for different industrial needs. Both are galvanized, meaning they are coated with a layer of zinc to enhance corrosion resistance—a critical advantage for parts exposed to moisture, humidity, or outdoor environments. This zinc coating acts as a protective barrier, preventing rust and extending the service life of the parts, even in harsh conditions.
SS55, defined under Japan’s JIS G3101 standard as a general structural rolled steel, offers a balanced combination of strength and ductility. With a maximum carbon content of 0.25%, it maintains good formability, making it easy to cut, bend, and weld without losing structural stability. Its tensile strength of ≥433 MPa and yield strength of ≥242 MPa ensure it can withstand moderate loads, while an elongation rate of ≥24% allows for flexibility in applications requiring slight deformation without cracking.
SS60, by contrast, is a high-carbon steel with a carbon content ranging from 0.57-0.65%. This higher carbon content gives it exceptional tensile strength (≥675 MPa) and yield strength (≥400 MPa), making it ideal for parts that need to bear heavy loads or resist wear. While its elongation rate (≥12%) is lower than SS55, it compensates with superior hardness and durability, especially after proper heat treatment.
Our laser cutting service is designed to maximize the potential of these materials. Equipped with state-of-the-art CNC laser cutting machines, we achieve tolerances as tight as ±0.1mm, ensuring precise cuts even for complex shapes and intricate designs. The laser cutting process minimizes material waste by optimizing nesting layouts, and it produces clean, burr-free edges that reduce the need for secondary finishing. Unlike traditional cutting methods, laser cutting does not apply mechanical force to the material, preventing warping or distortion—critical for maintaining the integrity of galvanized steel’s protective zinc coating.
In addition to laser cutting, we offer complementary services such as bending, welding, and surface treatment to meet comprehensive fabrication needs. All parts are customized based on customer drawings, with support for various sheet thicknesses, widths, and lengths. We accept orders starting from 1 piece, providing flexibility for prototypes, small-batch production, or large-scale manufacturing. Our quality control process includes rigorous inspections of material composition, dimensional accuracy, and surface finish, ensuring every part meets the highest industry standards.

Application Scenarios
The unique properties of SS55 and SS60 galvanized steel make them suitable for distinct but equally critical applications across industries:
SS55 Galvanized Steel Applications
Structural Engineering: As a general structural steel, SS55 is widely used in building frames, support beams, and roof trusses. Its balanced strength and ductility allow it to bear static and dynamic loads in construction projects, while the galvanized coating protects against rain and humidity.
Mechanical Components: SS55 is ideal for manufacturing machine bases, brackets, and enclosures. Its formability makes it easy to fabricate into complex shapes, and its corrosion resistance ensures longevity in factory environments.
Mold and Tooling: It serves as a reliable material for cold work mold pads, drilling mold fixing plates, and standard formwork. These parts require stability and precision, and SS55’s consistent mechanical properties meet these needs.
Automotive and Furniture: SS55 is used in automotive undercarriage parts (e.g., brackets) and furniture frames, where its combination of strength, corrosion resistance, and cost-effectiveness adds value.
SS60 Galvanized Steel Applications
Spring Manufacturing: SS60’s high tensile strength and hardness make it perfect for producing flat springs, coil springs, and seat springs. These parts need to withstand repeated compression and expansion, and SS60 maintains its elasticity over time.
Heavy-Duty Mechanical Parts: It is used to make shafts, wheel axles, cams, and gears—components that bear high friction and load. For example, in industrial machinery, SS60 gears resist wear even under continuous operation.
Automotive High-Strength Parts: SS60 is found in suspension springs, transmission components, and brake parts. These parts require exceptional strength to handle the stresses of driving, and SS60 delivers reliable performance.
Industrial Equipment: It is used in bearings, pump bodies, and conveyor system components. In manufacturing plants, these parts are exposed to heavy use, and SS60’s durability reduces maintenance frequency.
Frequently Asked Questions (FAQ)
What is the difference between SS55 and SS60, and how do I choose between them? The key difference lies in carbon content and mechanical properties: SS55 (low carbon) offers better ductility and formability, making it suitable for structural and general mechanical parts. SS60 (high carbon) provides higher strength and hardness, ideal for springs and high-load components. If your application requires flexibility and corrosion resistance, choose SS55; for parts needing to bear heavy loads or repeated stress, SS60 is better. Our technical team can help recommend the right grade based on your design.
How thick can the laser cutting service handle for SS55 and SS60 galvanized steel? Our laser cutting machines can process SS55 and SS60 galvanized steel sheets with thicknesses ranging from 0.3mm to 20mm. For thicknesses over 10mm, we may adjust cutting parameters to ensure precision. We recommend specifying the thickness in your drawings, and we will confirm feasibility before production.
Does the galvanized coating get damaged during laser cutting? Our laser cutting process is optimized to minimize damage to the zinc coating. The high-speed laser beam cuts through the steel with minimal heat input, reducing zinc oxidation at the cut edges. For critical applications, we offer post-cut zinc touch-up (e.g., zinc-rich paint) to restore corrosion resistance at the edges—this service is available upon request.
What is the lead time for custom laser cutting orders? Lead time depends on part complexity and order quantity. For simple shapes (e.g., flat plates with holes) in quantities of 1-100 pieces, we deliver within 3-5 working days. For complex designs or large orders (500+ pieces), lead times extend to 7-10 working days. We prioritize urgent orders and can arrange expedited production for an additional fee.
Can you provide material certification for SS55 and SS60? Yes, we supply certification for both grades, including chemical composition reports (verifying carbon, silicon, and manganese content) and mechanical property test results (tensile strength, yield strength). For SS55, we also provide JIS G3101 compliance documentation. This certification ensures the materials meet international standards and is available for all orders.
