The Challenge

Why This Product Exists

Commercial greenhouse construction typically requires separate procurement of steel frames from one manufacturer and glass panels from another, with a third party responsible for design integration. This fragmented approach leads to dimensional mismatches between frame and glass, inconsistent quality standards, finger-pointing when leaks or structural issues arise, and project delays when one supplier falls behind.

Vertical Integration

Same Expertise. Deeper Integration.

Will Enterprise is one of the few manufacturers globally that produces both the steel structural frame and the glass cladding for greenhouse construction. Our steel fabrication lines produce the hot-dip galvanized frames while our glass processing facility produces the tempered, Low-E, or diffused glass panels — all engineered to fit together with precision. For agricultural developers, this means one contract, one quality standard, and one point of responsibility for the entire greenhouse envelope.

Product Range

System Components

Venlo Greenhouse

The industry-standard Dutch design for commercial horticulture. Characterized by narrow spans (typically 9.6m or 12.8m) with peaked glass roofs that maximize light transmission. Our Venlo structures use hot-dip galvanized steel columns and trusses with 4mm tempered glass panels.

Key Specifications

  • Span: 9.6m / 12.8m
  • Gutter height: 4.0–6.5m
  • Glass: 4mm tempered float
  • Light transmission: 91%+
  • Snow load: up to 0.6 kN/m²

Multi-Span Greenhouse

Connected greenhouse bays for large-scale agricultural operations. Gothic arch or peaked roof profiles with spans from 8m to 16m. Ideal for operations requiring 10,000+ m² of growing area with uniform internal climate conditions.

Key Specifications

  • Span: 8m – 16m per bay
  • Unlimited bay connections
  • Gutter height: 3.5–7.0m
  • PC sheet or glass cladding
  • Wind resistance: 120 km/h

Single-Span Greenhouse

Standalone greenhouse structures for smaller operations, research facilities, and nurseries. Simple gable or gothic arch profiles with spans from 6m to 12m. Cost-effective entry point for controlled-environment agriculture.

Key Specifications

  • Span: 6m – 12m
  • Length: unlimited
  • Gutter height: 2.5–4.5m
  • Film, PC, or glass cladding
  • Foundation: concrete pier

Glass Greenhouse Panels

Specialized greenhouse glass processed in our architectural glass facility. Available in clear tempered, diffused (haze), and Low-E configurations. Diffused glass distributes light evenly across the growing area, improving crop uniformity by up to 10%.

Key Specifications

  • 4mm tempered float glass
  • Diffused glass (haze 40–80%)
  • Low-E for energy retention
  • Anti-reflective coating option
  • Max panel size: 1.6m × 2.4m

Why Will Enterprise

Key Advantages

Steel + Glass, One Manufacturer

We manufacture both the structural frame and the glass panels across our co-located facilities. No dimensional mismatches, no finger-pointing between suppliers, no coordination delays. One manufacturer, one responsibility.

Architectural-Grade Glass

Our greenhouse glass is processed on the same lines as our architectural glass products — tempered to EN 12150, with optional Low-E coating, diffusion, or anti-reflective treatment. Quality that exceeds standard horticultural glass.

20+ Year Frame Life

Hot-dip galvanization at 275g/m² provides the same corrosion protection as our structural steel buildings. The greenhouse frame is engineered to the same standards as a permanent building, not a temporary structure.

Complete Climate Control Integration

Our greenhouse structures are designed to integrate with heating, cooling, irrigation, and screening systems. We provide the structural provisions — mounting rails, cable trays, equipment foundations — as part of the standard package.

Where It's Used

Applications

Commercial Horticulture

Large-scale vegetable, flower, and herb production in controlled environments. Venlo and multi-span configurations for operations from 5,000 to 100,000+ m².

Nursery & Propagation

Seedling production, grafting, and plant propagation facilities requiring precise temperature and humidity control.

Cannabis & Medicinal Plants

Regulated growing facilities where light control, security, and environmental monitoring are critical compliance requirements.

Research & Education

University and government research greenhouses with specialized configurations for controlled experiments and teaching.

Agritourism & Retail

Garden centers, farm-to-table restaurants, and agritourism venues where the greenhouse serves both growing and customer-facing functions.

Tropical & Arid Climate Growing

Climate-adapted greenhouse designs for regions where external conditions require cooling, shading, or humidity management rather than heating.

Common Questions

Frequently Asked Questions

Most greenhouse manufacturers purchase steel and glass from separate suppliers and assemble them. Will Enterprise manufactures both the steel frame and the glass panels in-house. This means tighter dimensional tolerances between frame and glass (reducing leaks and thermal bridging), consistent material quality across both components, and a single point of responsibility for the entire structure.

Yes. Our glass processing facility applies the same Low-E coatings used in our architectural insulated glass units. For greenhouses, Low-E glass retains heat during cold nights while maintaining high light transmission during the day. We also offer anti-reflective coatings that increase light transmission from 91% to 95%+, and diffused glass that distributes light more evenly across the growing area.

Engineering and design takes 2–3 weeks after receiving your site survey and requirements. Manufacturing takes 4–6 weeks depending on size and complexity. Shipping to most global destinations takes 3–5 weeks. Total lead time from order to delivery is typically 10–14 weeks. Installation time depends on local conditions but typically ranges from 2–8 weeks for structures of 5,000–20,000 m².

We provide comprehensive installation support including detailed assembly manuals, installation supervision by our field engineers, and training for local installation crews. For projects above 10,000 m², we can deploy our own installation team. We also maintain a network of certified installation partners in key markets.

Absolutely. A common combination is greenhouse structures with our aluminum doors and windows for office/packing areas, and steel structures for adjacent warehouse or processing facilities. All components are manufactured in our integrated facility and can be containerized together for consolidated shipping.
