Services

Sainpoly provides full life-cycle services covering greenhouse projects. Each service is independently delivered by a senior team and can be flexibly combined into end-to-end solutions to ensure the efficient implementation and sustained revenue generation of your commercial greenhouse project.

Greenhouse Design

Based on local climate data and crop cultivation requirements, we deliver a complete design solution, from CAD construction drawings to load calculation sheets. Our design team averages over 7 years of professional experience and provides customized structural optimization for extreme climates, complex terrains, and special crops, ensuring the optimal balance between greenhouse safety and operational efficiency.

Greenhouse Manufacturing

Our in-house factory uses precision equipment including robotic welding, laser cutting, and automatic stamping to ensure standardized processing and accuracy. All steel components undergo hot-dip galvanizing for corrosion protection, with traceable coating thickness. We enforce a full-process quality control system, and all products are CE certified and meet import standards for the European Union, the Middle East, and Central Asia.

Greenhouse Construction

Senior engineers from the headquarters will be stationed on-site to guide local construction teams in completing assembly, providing detailed installation manuals and video tutorials. Alternatively, we can dispatch a professional construction team to take full responsibility for foundation work, main structure installation, and equipment commissioning, ensuring the greenhouse is fully operational upon delivery. In either case, strict acceptance checks are conducted at every project milestone to ensure both on-time delivery and quality compliance.

Technical Support

We provide a 24×7 multilingual remote support mechanism. We quickly diagnose equipment faults via video calls and remote data analysis, offering solutions to most issues within 30 minutes. We also maintain a spare parts warehouse, with routine parts shipped within 48 hours. Additionally, we provide annual online maintenance training to help your team master daily upkeep skills and minimize downtime risks.

Agricultural Consulting & Management

For clients who wish to focus on market operations or lack cultivation experience, our professional agronomists provide expert advice on crop selection, planting plans, water and fertilizer regimes, and environmental control parameter optimization. Alternatively, we can dispatch a dedicated management team to take full responsibility for daily greenhouse operations, helping you achieve a low-asset, high-return commercial planting model.
