Commercial Agricultural Greenhouse Structural ASTM A53 Certified Steel Pipe
YTDR Group presents ASTM A53 certified steel structural tubing, a high-performance solution tailored for commercial greenhouse frame projects. Engineered to meet the rigorous demands of global agriculture engineering, our tubing combines superior corrosion resistance, precise dimensional control, and full compliance with international standards, making it the first choice for overseas engineering contractors, procurement companies, and distributors.
Core Parameters (Quantified Hard Indicators)
- Material: Carbon steel (ASTM A53 Grade A/B, A106 Grade B), low alloy steel (A333 Grade 6) for extreme climate adaptability
- Specifications: Outer diameter (OD): 15mm-325mm; Wall thickness (WT): 1.5mm-12mm; Length: 6m-12m (customizable up to 18m for bulk orders); Tolerance: OD ±0.05mm, WT ±0.02mm, meeting ISO 13920 Grade 2 precision standards
- Process: Hot-rolled (HR), cold-drawn (CD), electric resistance welded (ERW) for seamless connection; heat treatment (normalizing, quenching) to enhance tensile strength
- Standard: ASTM A53, API 5L, API 5CT, EN 10217 (EU), JIS G 3452 (Japan)
- Surface Treatment: Hot-dip galvanizing (HDG) with 85μm-120μm coating thickness; electro-galvanizing; 3PE/2PE anti-corrosion coating; epoxy resin painting, passing salt spray test for 720 hours
Performance Advantages (Data & Test Supported)
- Corrosion Resistance: Hot-dip galvanized tubing achieves 720-hour neutral salt spray test without rust (test report by SGS), solving the pain point of rapid corrosion in high-humidity greenhouse environments. Compared with ordinary steel tubing, service life is extended by 300%.
- Pressure Resistance: Tensile strength ≥415MPa, yield strength ≥240MPa, elongation ≥20%, capable of withstanding 1.6MPa working pressure, avoiding frame deformation caused by heavy snow and strong winds (proven in North American winter greenhouse projects).
- Precision Control: Adopts CNC machining equipment, dimensional tolerance controlled within ±0.03mm, ensuring seamless assembly of greenhouse frames, reducing on-site construction time by 20% and labor costs for contractors.
- Non-standard Specifications: Custom outer diameter (15mm-500mm) and wall thickness (1.5mm-15mm) for special greenhouse designs, such as tall-span greenhouse frames (minimum order quantity: 5 tons).
- Surface Treatment: Custom 3PE/2PE anti-corrosion coating for coastal greenhouses (resisting salt fog erosion) and epoxy resin painting for indoor hydroponic greenhouses (meeting food safety standards).
- Connection Methods: Threaded connection (NPT/BSPT), flange connection (ANSI/EN standard), and beveled edge processing for welding, matching different greenhouse assembly requirements.
- Packaging: Export-standard wooden crates or galvanized steel pallets, with moisture-proof and anti-collision treatment, suitable for long-distance sea transportation (compliant with ISPM 15 standards to avoid port detention).
Our commercial greenhouse structural tubing is fully certified to meet global market access requirements, including: API 5L/API 5CT (for extended application in agricultural irrigation with oil-gas mixed pipelines), CE certification (EU market access), ISO 9001:2015 quality management system certification, SGS/BV third-party inspection reports (customizable for each batch), and Certificate of Origin (CO) for tariff preferences. All certifications are traceable via official platforms, eliminating customs clearance risks for overseas clients.
