Advanced Light Diffusion Engineering: Custom-patterned micro-textures (Prismatic / Matt) convert intense direct solar glare into uniform scattered light, driving Photosynthetically Active Radiation (PAR) deep into dense lower crop leaves.
Precision Tailored Haze Classifications: Configurable across Low Haze (~20%), Medium Haze (~40%-50%), and High Haze (~70%) matrices to perfectly match specific regional sunlight indexes and crop light requirements.
Thermal Burn & Hotspot Elimination: Neutralizes localized heat concentrations at the greenhouse crown, preventing apical bud and blossom scorching while eliminating shadows cast by internal structural trusses.
High Base Light Transmittance: Manufactured from ultra-pure raw materials with iron oxide content Fe2O3 ≤ 0.015%, delivering a high base hemispherical light transmittance of ≥ 91.5%.
High-Impact Hail & Wind Safety Rating: Available in 3.2 mm and 4.0 mm physical toughening with strict European/US safety certifications, featuring a minimal spontaneous breakage rate below 0.05%.

Are you constructing a commercial glasshouse for tall vining crops (such as tomatoes, cucumbers, or sweet peppers), or designing a high-yield floriculture greenhouse in a high-UV climate zone? Shandong Weihua Glass manufactures premium Diffused Low-Iron Patterned Glass (Ultra-Clear Prismatic & Matt Greenhouse Roof Glass) engineered specifically to revolutionize light distribution inside high-tech agricultural enclosures.
In traditional greenhouse construction with clear float glass, direct sunlight hits only the top crown of the plants, creating intense hotspots that scorch upper leaves while leaving middle and lower leaves in deep shadow. Weihua's diffused patterned glass resolves this physiological bottleneck. By imprinting precision geometric micro-structures onto ultra-low-iron glass molten sheets, we refract direct solar beams into soft, non-directional diffused light rays. This ensures every leaf layer receives optimal photon density, dramatically boosting overall plant photosynthesis and harvest yield.
Haze determines the percentage of light that is scattered away from the direct incident beam by more than 2.5°. Weihua offers three distinct haze configurations to suit your regional climate and crop biology:
Light Characteristics: Delivers gentle diffusion while maintaining high direct light throughput.
Target Regions & Crops: Low-light high-latitude regions, winter production zones, or light-sensitive crops requiring maximum direct photons.
Light Characteristics: The ideal architectural balance between high light transmission and deep canopy light scattering.
Target Regions & Crops: Temperate climate zones; universally applied for commercial tomato, pepper, and cucumber glasshouses.
Light Characteristics: Maximum light scattering capability that virtually eliminates internal structural shadows.
Target Regions & Crops: Tropical or high-altitude regions with harsh solar radiation; ideal for high-density multi-tier vertical farming and delicate floriculture.
Technical Indicator | Specifications & Value Range | Agronomic & Engineering Benefit |
Iron Oxide Content (Fe2O3) | ≤ 0.015% (150 ppm) | Eliminates greenish glass tint; maximizes solar spectrum entry. |
Base Light Transmittance | ≥ 91.5% - 92.0% | High baseline photon passage for un-coated raw panes. |
Surface Pattern Textures | Prismatic / Matt | Matt / Matt | Precision micro-embossing that scatters solar rays uniformly. |
Standard Thickness Options | 3.2 mm / 4.0 mm | Lightweight 3.2 mm tempered panes reduce roof load stress. |
Spontaneous Explosion Rate | < 0.05% | Ultra-pure raw materials control NiS impurities; storm & hail safe. |
Compliance & Standards | EN 12150 (Tempered Safety), GB 15763.2 | Certified physical impact resistance for commercial greenhouse roofs. |
Precision Multi-Haze Customization: Not all crops thrive under the same diffusion levels. Weihua's technical division calibrates the micro-pattern depth during rolling to deliver custom haze ratings (20\% - 70\%), ensuring your greenhouse roof matches your exact regional climate and crop light requirements.
100% Factory Sizing & Frame Synchronization: Ordering glass panes that do not fit the roof aluminum gutters causes costly installation delays. Weihua works directly with your structural CAD submittals, delivering CNC-cut, bevel-edged tempered glass panels that drop seamlessly into your roof framing system.
Elite Glass & Hardware System Integration: Sourcing greenhouse glass from one supplier and roof capping profiles or rubber gaskets from another often leads to sizing errors and seal failures. Weihua provides complete system integration—pre-matching glass pane dimensions with custom EPDM gaskets, aluminum capping profiles, and structural fasteners.
Engineered Moisture-Proof Maritime Packaging: Ocean freight transit can cause moisture staining (white haze) on raw glass surfaces. Weihua packs all agricultural glass inside reinforced L-frame timber crates lined with moisture-barrier films, non-reactive interleaving powder, and desiccant packs, ensuring pristine, scratch-free surfaces upon delivery.
