Hot-Dipped Galvanized Greenhouse Steel Pipes for Commercial Agricultural
YTDR Group is a leading global supplier of hot-dipped galvanized greenhouse steel pipes, specializing in providing high-performance structural solutions for commercial agricultural projects worldwide. Our products are engineered to meet the rigorous demands of B2B clients (engineering firms, procurement companies, and distributors) by combining superior material quality, advanced manufacturing processes, and tailored services. As a core offering of YTDR Group, these hot-dipped galvanized greenhouse steel pipes have been widely applied in large-scale commercial greenhouses across Europe, the Middle East, and North America, helping clients reduce construction costs while enhancing the durability and stability of their greenhouse structures.
Core Parameters (Quantified Hard Indicators)
● Material: Q235B, Q355B, and S235JR carbon steel; customizable to stainless steel (304/316) for high-corrosion environments
● Specifications: Outer diameter (OD): 20mm – 219mm; Wall thickness (WT): 1.2mm – 8.0mm; Length: 6m, 12m (fixed) or custom lengths (3m – 18m) as required
● Process: Hot-dipped galvanizing process (immersion of steel pipes in molten zinc at 450°C); precision cold-drawn forming for seamless pipes, high-frequency welding for ERW pipes
● Standards: Complies with EN 10219, ASTM A53, GB/T 3091-2015, and DIN 2448 international standards
● Surface Treatment: Hot-dipped galvanizing with a zinc coating thickness of 85μm – 120μm; passivation treatment optional to enhance corrosion resistance; no surface defects such as bubbles, cracks, or uneven coating
Product Positioning
YTDR Group’s hot-dipped galvanized greenhouse steel pipes are positioned as high-performance structural materials for large-scale commercial agricultural projects, including vegetable cultivation greenhouses, flower planting greenhouses, hydroponic system greenhouses, and polycarbonate/glass greenhouses. The product is specially designed for B2B clients with high requirements for durability, corrosion resistance, and structural stability, and is suitable for agricultural engineering projects in various climates (tropical, temperate, and frigid zones).
Performance Advantages (Data & Test Supported)
● Corrosion Resistance Solution: Targets the pain point of steel pipe rusting in humid greenhouse environments. Our hot-dipped galvanizing process forms a dense zinc layer on the pipe surface, which provides cathodic protection. Tested by SGS, the corrosion resistance service life of the pipes reaches 20+ years in normal greenhouse environments, and 15+ years in coastal high-salt spray areas, which is 3 times that of pre-galvanized steel pipes.
● Pressure Resistance & Load-Bearing Solution: Targets the pain point of structural collapse due to insufficient strength of greenhouse frames. The pipes are made of high-quality Q355B steel, with a yield strength of 355MPa and a tensile strength of 470-630MPa. They can withstand a maximum snow load of 1.2kN/m² and a wind load of 0.8kN/m², fully meeting the structural requirements of large-span commercial greenhouses (span up to 16m).
● Precision Control Solution: Targets the pain point of difficult assembly due to inconsistent pipe dimensions. Our pipes are manufactured with advanced CNC processing equipment, with a dimensional tolerance of ±0.1mm for outer diameter and ±0.05mm for wall thickness. The straightness error is less than 1mm/m, ensuring quick and accurate assembly of greenhouse frames, and reducing on-site construction time by 20%.
YTDR Group has a professional R&D and production team to provide one-stop customization services for clients, with no minimum order quantity (MOQ) limit for large-scale projects. Customizable dimensions include:
● Specifications Customization: Non-standard outer diameter (20mm – 300mm), wall thickness (1.0mm – 10.0mm), and length (3m – 24m); thickened wall design for high-load greenhouses
● Surface Treatment Customization: 3PE anti-corrosion coating (for extreme corrosion environments), epoxy resin coating (for food-grade hydroponic greenhouses), and color-coated galvanizing (for aesthetic requirements)
● Connection Method Customization: Thread processing (NPT/BSP), flange connection (custom flange size), bevel processing (for welding), and quick-connect fitting installation (for easy disassembly)
● Packaging Customization: Export standard wooden cases, steel pallets, or waterproof packaging; customized marking (client logo, product specifications, batch number) to meet international shipping and storage requirements
