Welded Steel Truss Single-Slope Solar Greenhouse

Ruize manufactures the Welded Steel Truss Single-Slope Solar Greenhouse in China and supplies it as a manufacturer, supplier and factory for large agricultural projects. Its defining feature is the welded triangular truss, formed by upper and lower chords with diagonal members welded into one structural assembly. Compared with a simple single-tube frame, this configuration provides a more substantial load-bearing structure for projects where span, snow load and wind resistance are important considerations.

The greenhouse retains the basic solar-greenhouse concept of a large front slope and insulated rear section, but places greater emphasis on structural capacity. It is intended for commercial planting bases, agricultural parks and other projects where the greenhouse needs to accommodate a wider internal working area together with heavier covering, insulation or auxiliary equipment.

What the Welded Truss Changes

Triangular Load-bearing Geometry

The frame uses welded triangular trusses rather than relying on individual round or oval tubes as the main roof support. The upper chord, lower chord and diagonal members work together to distribute loads through the truss structure.

• Greater structural stiffness than a simple single-tube frame
• More even distribution of roof and environmental loads
• Suitable for larger spans and heavier greenhouse configurations
• Adaptable to project-specific wind and snow load requirements

This design is particularly relevant in areas where accumulated snow, strong seasonal winds or larger greenhouse dimensions place greater demands on the supporting frame. Final truss dimensions, spacing and foundation design should be calculated according to local conditions.

Single-slope Solar Design for Winter Growing

Front Slope for Solar Collection

The front slope is designed around winter solar exposure, allowing the greenhouse to make use of available sunlight during the day. The slope angle can be planned according to the project location, greenhouse dimensions and crop requirements.

Suitable greenhouse films can be selected based on light transmission, low-temperature performance, durability and the intended crop. PE, PO and EVA film options can be considered for different greenhouse configurations.

Rear Section for Heat Retention

The rear wall and rear-slope structure provide the main thermal-retention function. Insulation materials can be incorporated into the rear section to reduce heat loss after sunset and help create a more stable internal environment during winter.

Where temperatures are too low for passive heat retention alone, the greenhouse can be combined with thermal blankets and heating equipment. The required configuration depends on local winter temperatures, crop temperature requirements and the greenhouse's operating conditions.

Full-frame Hot-dip Galvanizing

The steel frame is treated with hot-dip galvanizing for outdoor corrosion protection. Because welded structures contain numerous connection points, the treatment of welded areas is an important part of long-term maintenance.

The supplied production process includes preparation of the steel surface, welding, grinding of relevant weld areas, zinc repair treatment and passivation. The aim is to maintain corrosion protection across both the main steel members and the processed connection areas.

Under suitable environmental and maintenance conditions, the galvanized steel structure is intended for long-term outdoor use. The actual service life varies with climate, coating condition, structural loading and maintenance frequency.

Large-span Space for Agricultural Operations

The welded truss configuration can be used where a larger clear growing area is required. By planning the truss span and support arrangement as part of the overall structural design, the greenhouse can provide space for crop rows, harvesting, internal transportation and selected agricultural machinery.

For connected greenhouse projects, service aisles and equipment access can be planned at the same time as the truss layout. This helps separate cultivation areas from transportation routes and makes larger planting operations easier to organize.

Configuration Reference

Equipment for Controlled Winter Production

The greenhouse frame can support the integration of environmental-control systems selected according to the project. The reinforced structural design is useful where additional insulation or equipment needs to be incorporated into the greenhouse configuration.

• Electric heavy-duty thermal blanket system
• Automatic top and side ventilation film openers
• Air circulation fans
• Integrated water and fertilizer system
• Winter heating units
• Internal and external shading systems
• Remote temperature and humidity monitoring
• Reinforced rainwater drainage system

Equipment selection should be based on the crop, greenhouse volume, local climate and required operating temperature rather than applying one standard package to every project.

Suitable for Large Agricultural Projects

The structure is intended for projects where heavy-duty framing and winter crop protection are both important.

• Large agricultural planting parks in cold regions
• Winter cultivation of medicinal plants
• Premium fruit and vegetable production bases
• Large-scale seedling facilities
• High-standard agricultural demonstration projects
• Commercial off-season crop production
• Overseas agricultural engineering projects

Designed Around Local Wind and Snow Conditions

The truss structure can be engineered around the environmental loads of the project location. Wind speed, snow load, elevation, greenhouse span, frame spacing and foundation conditions should all be considered when determining the final structural specification.

This project-based approach is particularly important for high-latitude or high-altitude sites, where snow accumulation, strong winds and large seasonal temperature differences can impose substantially different structural requirements from those of a conventional agricultural greenhouse.

From Fabrication to Overseas Installation

Ruize can coordinate steel fabrication, welding, galvanizing, greenhouse covering materials and selected supporting components for export projects. The greenhouse structure can be divided into transportable sections for reinforced export packing and container loading.

Project documentation can include structural drawings, installation instructions and technical videos. For larger overseas agricultural projects, remote technical guidance can be provided during assembly and commissioning, with replacement frame components and greenhouse film available for later maintenance.

Maintenance of the Welded Frame

Regular inspection should focus on the galvanized coating, welded and repaired areas, connecting points, greenhouse film, drainage paths and supporting equipment. Particular attention should be given to the structure before and after periods of heavy snowfall or strong winds.

Where a covering panel, connector or other individual component is damaged, the relevant part can generally be replaced without removing the complete greenhouse frame. This helps simplify maintenance for long-term commercial growing projects.

Frequently Asked Questions

What is the main difference between the welded truss greenhouse and a conventional tube frame?

The main difference is the load-bearing structure. The welded version uses triangular trusses composed of upper and lower chords plus diagonal members, creating a more rigid structural assembly that is better suited to larger spans and higher design loads.

Can the greenhouse be designed for heavy snow areas?

Yes. The truss configuration can be engineered for higher snow loads, but the final structure must be calculated according to the actual local snow conditions, span, frame spacing and foundation design. A heavy-duty frame does not replace site-specific structural engineering.

Can the greenhouse support additional thermal equipment?

The reinforced truss structure can be considered when integrating thermal blankets and selected auxiliary equipment. Equipment weight, fixing method and load position should be confirmed during structural planning.

Can the greenhouse provide a large working area for agricultural machinery?

Yes. Larger spans can be planned to provide more open internal space for planting, harvesting and material handling. The final clear width and internal support arrangement depend on structural calculations and the dimensions of the machinery being used.

Can the structure be customized for an overseas project?

Yes. The truss specification, span, height, spacing and overall greenhouse dimensions can be adjusted according to local wind, snow, elevation and site conditions. Supporting film, insulation and environmental-control systems can also be selected as part of the project configuration.
