As a specialized manufacturer with over two decades of experience since 2003, QinHuangDao LianYiDing Glass Co., Ltd. proudly offers premium 4mm Tempered Horticultural Glass Panels, engineered specifically for demanding greenhouse roofing applications. Our commitment to stringent ISO9001, ISO14000, and ISO19011:2000 quality management systems ensures every panel meets the highest standards of durability, clarity, and safety. Designed to optimize plant growth environments, these panels provide superior light diffusion and structural integrity, making them an essential investment for professional horticulture operations seeking reliable, long-lasting roofing solutions.
Core Product Advantages & Technical Specifications:
- Superior Strength & Safety: Undergoes rigorous thermal tempering, increasing impact resistance 4-5 times compared to annealed glass. Upon breakage, shatters into small, granular pieces, significantly reducing the risk of injury – a critical safety feature for structures over people and valuable crops.
- Optimal Light Transmission: Engineered for horticulture, our clear tempered glass offers high light transmission (typically >90% for clear glass), ensuring maximum photosynthetic active radiation (PAR) reaches plants. This promotes uniform growth and higher yields.
- Enhanced Durability: The tempering process creates surface compression, making the glass highly resistant to thermal stress (common in greenhouses), wind load, hail impact, and minor physical abrasions encountered during installation or maintenance.
- Weather & UV Resistance: Impervious to degradation from sunlight (UV radiation), rain, snow, and temperature extremes. Maintains clarity and structural performance year after year without yellowing or becoming brittle.
- Thermal Efficiency: While single pane, the 4mm thickness provides a good balance between light admission and basic thermal insulation properties. Can be integrated into double-glazing systems upon request for enhanced insulation.
- Precision Manufacturing: Panels feature cleanly seamed edges to minimize stress points and ensure safe handling. Standard rectangular shapes are readily available, with custom sizes and shapes (e.g., trapezoidal) manufactured to precise specifications.

Frequently Asked Questions (FAQ):
-
Q: Why is 4mm thickness commonly used for greenhouse roofing?
A: 4mm offers an excellent balance between strength, weight, light transmission, and cost-effectiveness for most standard greenhouse applications. It provides sufficient structural integrity against typical wind/snow loads and hail impact while maximizing light entry crucial for plant growth. -
Q: How does tempered glass improve safety in a greenhouse?
A: When broken, tempered glass shatters into small, relatively blunt granular pieces instead of large, sharp shards. This drastically reduces the risk of serious injury to personnel working below or damage to plants from falling sharp glass. -
Q: Can this glass be cut or drilled after tempering?
A: No. Tempering is the final manufacturing process. Any attempt to cut, drill, or significantly alter the shape of tempered glass will cause it to shatter completely. All cutting and edge work must be done before tempering. Ensure your dimensions are accurate when ordering. -
Q: Are your ISO certifications valid and up-to-date?
A: Yes, QinHuangDao LianYiDing Glass Co., Ltd. maintains current certifications for ISO9001 (Quality Management Systems), ISO14000 (Environmental Management Systems), and ISO19011:2000 (Guidelines for quality and/or environmental management systems auditing). These underpin our consistent production quality. -
Q: What are the standard sizes available, and can I get custom sizes?
A: We stock common sizes suitable for various greenhouse framing systems, but custom sizes and shapes are a core strength. We manufacture panels to your exact specifications (within technical feasibility limits). Provide your required dimensions and quantity for a quote. -
Q: How is the glass packaged for export to prevent breakage?
A: Panels are carefully stacked, separated by protective interleaving material (like foam or paper), securely strapped onto sturdy wooden crates or A-frames, and clearly marked with handling instructions. This industry-standard packaging ensures safe transit to our global markets via Tianjin, Dalian, or Qinhuangdao ports. -
Q: Does this glass provide any UV filtering for plants?
A: Standard clear soda-lime glass naturally blocks most UV-B radiation but transmits UV-A and the vital PAR spectrum. It does not have special UV-blocking coatings unless specifically requested as a custom option. For most crops, the standard transmission profile is ideal. -
Q: What is the lead time for custom orders?
A: Lead times vary based on order volume, complexity, and current production schedule. Typically, standard custom orders ship within 3-5 weeks after order confirmation. We provide estimated lead times with every quotation. Contact us for your specific project timeline.
