Technical QA/QC Verification
• Precision Elcometer Zinc Coating & Paint Film Audits: SXY Steel Group enforces absolute structural compliance parameters. Every production run of PPGI structural Q235 steel coil undergoes strict Elcometer thickness auditing alongside intensive cross-hatch paint adhesion metrics and T-bend structural mapping. This guarantees zero paint cracking, flaking, or early micro-delamination during high-velocity profiling and cold roll-forming operations.
• EN 10204 3.1 Material Test Certificates (MTC) & Spectrophotometer Control: All shipments are fully traceable and dispatched with original factory MTC documentation recording exact steel chemical heat numbers, structural yield thresholds, and digital spectrophotometer color matching verification. Every order is fully prepared for independent verification by premium inspection bodies including SGS, Bureau Veritas, or Intertek.
• Sovereign Capital Security Framework: To insulate global commercial buyers, distributors, and engineering firms from foreign exchange fluctuations and unforeseen project liabilities, we process and confirm all high-volume supply contracts under 100% Irrevocable Letters of Credit (L/C) at sight financial protocols.
Internal Protection & Ocean Logistics
• Continuous Surface Protective Film & Anti-Moisture Vapor Barriers: Finished paint surfaces are highly sensitive to transit friction. We apply a continuous thick PE protective layer directly to the decorative surface. Coils are then encapsulated in heavy waterproof kraft wrap, completely sealed within a high-density plastic moisture barrier with desiccant packs, and encased in galvanized outer steel protection to eliminate sea-air condensation and white rust damage.
• Heavy-Duty Fumigated Export Palletization & Rigid Shoring: Cargo lots are securely strapped to robust, ISPM-15 compliant timber skids using heavy-gauge high-tensile steel banding. Coils are locked down inside maritime shipping containers with solid timber bracing and steel wire tie-backs to ensure completely stable maritime transport parameters.
• Complimentary 14-21 Days Extended Destination Port Demurrage Buffer: SXY Steel Group pre-embeds up to 21 days of extended free container demurrage into your maritime Bill of Lading, protecting your local customs clearance brokers from severe port terminal administrative penalties.
Q235 galvanized coil is a surface galvanized coil with yield strength of 235MPa.
PPGI is galvanized color plate, PPGL is galvanized color plate, both are color plates, the substrates are different, one is galvanized structure, the other is galvanized structure, the substrate is different, which determines the difference in performance.
Advantages: It not only has the mechanical strength and easy forming properties of steel plates, but also has good decorative properties and corrosion resistance of organic materials. The coating has strong adhesion and can keep the color fresh for a long time. Application: Widely used in various fields such as construction, home appliances, furniture, public facilities and transportation.
Packing and shipping
Our company has passed ISO9001 quality management system certification, Our Mill product with CE/EN10204 / ASTM/Classification society certificate/CASO/BIS etc certificate.All the customers give good appreciation to our products.We are glad to be your good partner.
Application Areas
Steel is widely used in steel structure workshops, bridge frames, main structures of high-rise buildings, and infrastructure construction (such as highways, oil and gas pipelines). Its high strength properties ensure load-bearing stability and seismic performance. In ship manufacturing, steel is used to build hull structures, decks, and internal components. Hot-rolled coils rely on their load-bearing capacity to adapt to harsh environments.
Factory workshop
With a commitment to excellence, innovation, and sustainability, the company has established itself as a trusted partner in the international steel industry.After nearly two decades of relentless endeavour, our client base now spans over 110 countries and regions across Europe, the Middle East, South America, and Southeast Asia.
