Technical QA/QC Verification
• 100% Traceable Mill Test Certificates: Deliveries are strictly backed by complete EN 10204 3.1 Mill Test Certificates (MTC) detailing ladle chemical properties, yield and tensile performance, hydrostatic pressure logs, and flattening/bending tests. Fully pre-approved for independent visual audits by SGS, Bureau Veritas, or Intertek.
• Capital Security Guarantee: We completely neutralize international cross-border purchasing risks by accepting long-term framework piping and infrastructure allocations funded via 100% Irrevocable Letters of Credit (L/C) at sight payment structures.
Anti-Rust Packaging & Ocean Logistics
• Fortified Structural Cargo Maritime Stowing: Bundles are systematically loaded onto heavy timber dunnage blocks inside shipping containers or breakbulk holds, secured with reinforced high-strength nylon lashing bands to neutralize shifting, metal friction, and structural bending risks during long ocean transits.
• Complimentary Extended Port Demurrage: SXY Steel Group coordinates 14 to 21 days of complimentary container and vessel demurrage directly at your exact destination terminal to guarantee sufficient clearing windows for your regional customs brokers and local truck lines.
In order to improve the corrosion resistance of steel pipes, general steel pipes are galvanized. Galvanized welded pipe is divided into hot galvanizing and cold galvanizing. Cold galvanizing is generally used less. Hot dip galvanized pipe is to make molten metal react with iron substrate to produce alloy layer, so that the substrate and coating can be combined. Hot galvanizing refers to pickling the steel pipe first. In order to remove iron oxide on the steel pipe surface, after pickling, the steel pipe is cleaned in ammonium chloride or zinc chloride aqueous solution or mixed ammonium chloride and zinc chloride aqueous solution tank, and then sent to the hot dip tank. Hot dip galvanizing has the advantages of even coating, strong adhesion and long service life.

Hot-dip galvanized steel pipes are widely used in the manufacturing industries of construction, machinery, coal mining, chemical industry, electric power, railway vehicles, automobile industry, highways, bridges, containers, sports facilities, agricultural machinery, petroleum machinery, prospecting machinery, shed construction, etc.
Galvanized steel pipe has a welded steel pipe with a hot dip or electro galvanized layer on the surface. Galvanization can increase the corrosion resistance of steel pipes and prolong the service life. Galvanized steel pipe has a wide range of uses, in addition to being used as a pipeline for general low pressure fluids such as water, gas and oil, it is also used as an oil well pipe and oil pipeline in the petroleum industry, especially in the marine oil fields, as an oil heater, condensation cooler and coal distillation and oil washing exchanger pipe for chemical coking equipment, and as a support frame pipe for trestle piles and mining pits, etc.
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.
