The new high-strength, pillarless greenhouse frame brings a revolutionary change to traditional greenhouse structures, offering significant advantages over conventional steel, cement, and bamboo frames. Here’s a closer look at its key features: First, it delivers exceptional strength and toughness. The frame is constructed using nano-activated composite materials that enhance the skeleton's compactness, durability, and resilience. Advanced reinforcement techniques during production ensure superior structural integrity. According to tests conducted by the National Building Decoration Materials Quality Supervision and Inspection Center, the flexural strength of a single frame reaches 3,866 N—equivalent to supporting the weight of 400 kg, or about six adults. Additionally, flexible ribs are integrated into the design, making the frame more resistant to impact and breakage. Second, it exhibits excellent water resistance, corrosion resistance, and flame retardancy. After being immersed in water, sulfuric acid, and sodium hydroxide solutions for 200 hours, no cracks, swelling, or fragmentation were observed. A 1000g steel ball dropped from 3 meters also failed to cause any damage. The use of non-combustible materials ensures the frame remains safe and durable in both wet and fire-prone environments. Third, it can withstand extreme freeze-thaw cycles. After 20 cycles at -25°C, the skeleton showed no signs of cracking or delamination—equivalent to 20 years of harsh winter conditions. This makes it ideal for regions like northern China, where temperature fluctuations can severely damage traditional structures. Fourth, the frame maintains stable humidity and significantly extends its service life. A moisture-proof outer layer is applied during manufacturing, preventing internal moisture loss and ensuring a balanced environment inside. As a result, the frame can last up to 15–20 years, far exceeding the lifespan of conventional options. Fifth, the absence of pillars creates a spacious, open interior with improved lighting and land utilization. The frame can be customized in length, span, height, and color, allowing for flexible designs without any obstructions. This eliminates dark corners and enables efficient mechanized farming. Its innovative structure marks a major breakthrough in greenhouse technology. Lastly, the frame is lightweight, cost-effective, and aesthetically pleasing. It weighs only one-third of a cement frame and costs around 3,000 yuan per mu, making it a more affordable and profitable option. Its smooth surface prevents film damage, extending the lifespan of the covering material while maintaining an elegant appearance.
