Leg-Together Round-Arch Simple Multi-Span Greenhouse

Ruize produces the Leg-Together Round-Arch Simple Multi-Span Greenhouse for commercial growing projects in windy, rainy and light-snow regions. Its key structural change is the paired-leg arrangement: two parallel steel pipes are used at the sides of the arch and extend to the ground together, creating a wider and more stable support point than a conventional single-pipe arch leg.

This reinforcement is aimed at the practical problems that can appear in simple multi-span greenhouses under stronger weather conditions, including noticeable shaking, frame deformation and loosened connection fittings. The structure keeps the basic simple multi-span format while strengthening the areas that carry the load down to the ground.

What the Paired-leg Structure Improves

Two Pipes for Ground Support

The two parallel arch legs provide additional structural support at both sides of each span. Instead of concentrating the load through a single pipe, the paired arrangement creates a reinforced support section at the ground connection.

• Parallel double-pipe support at both sides of the arch
• Improved resistance to structural movement under wind
• Greater support capacity than the standard single-pipe arrangement
• Suitable for projects requiring more stable multi-span framing

The final pipe size, spacing and connection arrangement should be selected according to the local wind and snow conditions of the installation site.

Round-Arch Roof Without Changing the Basic Growing Environment

The reinforcement is concentrated around the supporting legs, while the roof remains a round-arch form. This allows the greenhouse to retain the basic advantages of the curved roof without introducing a flat roof section or a different cultivation layout.

The curved profile helps rainwater move off the covering and provides a relatively open roof surface for natural light. It also avoids the need to replace the simple arch configuration with a much heavier greenhouse structure.

Simple Multi-span Layout for Commercial Planting

The Leg-Together Round-Arch Simple Multi-Span Greenhouse can be arranged as multiple connected spans for larger growing areas. The multi-span format makes it possible to organize several planting sections under a coordinated greenhouse layout while retaining a relatively simple structural system.

For commercial growing sites, the layout can be planned around planting rows, working paths and the available land. The reinforced side supports are positioned at the structural edges rather than adding unnecessary supports throughout the central growing area.

Prefabricated Assembly Without On-site Welding

The greenhouse retains the prefabricated assembly method of a simple multi-span structure. Frame components and connecting fittings are prepared before installation and assembled using clips and connection hardware rather than relying on field welding.

• Factory-prefabricated steel components
• Connection-based assembly
• No on-site welding for the main frame
• Suitable for overseas projects with limited welding resources

This means the paired-leg reinforcement does not require a completely different installation process from the basic simple multi-span structure, helping keep construction relatively straightforward.

Structural Durability

The paired-leg configuration helps distribute structural forces across the reinforced support area and reduces the dependence on a single leg at each side of the arch. The supplied product information states that the reinforced structure can provide a longer service life than the ordinary simple multi-span configuration.

Actual durability depends on the steel specification, local climate, foundation conditions, wind exposure and routine inspection. For sites with stronger weather conditions, the reinforcement level should be selected during project design rather than added only after installation.
