Heavy-Duty Greenhouse Steel Tubes Galvanized Material for Flowers Greenhouse
YTDR Group is a trusted global manufacturer and supplier of heavy-duty galvanized greenhouse steel tubes, dedicated to delivering high-performance structural solutions for large-scale greenhouse construction projects. Catering exclusively to B2B clients including engineering contractors, agricultural procurement companies, and global distributors, our products are engineered to address the most stringent challenges in greenhouse infrastructure—from extreme weather resistance to long-term structural durability. With a focus on precision manufacturing and compliance with international standards, YTDR’s heavy-duty galvanized greenhouse steel tubes have become the preferred choice for commercial greenhouse projects across Europe, Asia, and the Americas, driving efficiency and reducing lifecycle costs for our partners.
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
Performance Advantages (Data & Test Supported)
● Corrosion Resistance (Pain Point: Rapid rusting in humid greenhouse environments): Our hot-dipped galvanized coating provides cathodic protection, preventing steel oxidation even in 95% humidity conditions. Tested by SGS, the service life of our tubes reaches 25+ years in normal greenhouse environments and 20+ years in coastal high-salt spray areas—twice the lifespan of pre-galvanized steel tubes. This eliminates the need for frequent replacement, reducing lifecycle costs by 40% for clients.
● Pressure & Load-Bearing Capacity (Pain Point: Structural collapse under heavy snow or wind): Made from Q355B high-strength steel, our heavy-duty greenhouse steel tubes have a yield strength of 355MPa and a tensile strength of 470-630MPa. They can withstand a maximum snow load of 1.5kN/m² and a wind load of 1.0kN/m², making them suitable for large-span greenhouses (up to 30m span) without additional support structures. This reduces construction complexity and shortens project timelines by 15%.
● Precision (Pain Point: Difficult assembly due to inconsistent dimensions): Manufactured with CNC processing equipment, our tubes have a dimensional tolerance of ±0.08mm for outer diameter and ±0.05mm for wall thickness. The straightness error is less than 0.8mm/m, ensuring a perfect fit with greenhouse connectors (e.g., brackets, clamps). This reduces on-site assembly time by 20% and minimizes material waste by 10%.
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 (25mm – 400mm), wall thickness (1.5mm – 15.0mm), and length (3m – 30m); extra-heavy-duty wall thickness (10mm – 15mm) for ultra-large-span greenhouse projects (30m+ span).
● Surface Treatment Customization: 3PE anti-corrosion coating (for extreme corrosion environments such as coastal areas or chemical fertilizer-intensive farms); epoxy resin coating (for food-grade hydroponic greenhouses to prevent heavy metal contamination); color-coated galvanizing (for aesthetic requirements or brand consistency).
● Connection Method Customization: Thread processing (NPT/BSP standards for easy assembly); flange connection (custom flange sizes for large-diameter tubes); bevel processing (for welding in structural joints); quick-connect fitting installation (for modular greenhouse designs that require easy disassembly and relocation).
● Packaging Customization: Export standard wooden cases (for small-diameter tubes), steel pallets (for large-diameter tubes), or waterproof packaging (for long-distance sea transportation); customized marking (client logo, product specifications, batch number, and country of origin) to meet international shipping and storage requirements. No additional packaging fees for bulk orders (100+ tons).
