The U25, U29, U36 Curved Steel Arch Roof is primarily used for secondary support in mine laneways and for supporting mountain tunnels, providing stability and safety in mining operations.
The U-channel steel support arch is made from high-grade steel, specifically 20MnK or Q235, ensuring durability and strength.
The theoretical weight varies by specification: U25 weighs 24.95 kg/m, U29 weighs 29 kg/m, and U36 weighs 35.87 kg/m.
The U-channel steel support arch is available in lengths of 8m, 9m, 10m, and 12m, allowing for flexibility in installation.
The arch effectively reduces the risk of roof caving, thereby preventing accidents and enhancing the overall safety of mine ventilation systems.
The U-channel steel support arch complies with GB and QB standards, ensuring quality and reliability in mining applications.
While primarily designed for mining support, the U-channel steel arch can be adapted for other underground support applications, depending on specific requirements.
Installation of the U-channel steel support arch should be conducted by trained professionals to ensure proper alignment and stability, but the design allows for relatively straightforward installation.
U-channel steel supports offer greater durability, lower maintenance needs, and enhanced load-bearing capacity compared to traditional timber supports.
The U-shape design provides improved structural integrity and flexibility, allowing it to better absorb and distribute loads, which is crucial in mining environments.
The U-channel steel support arch is manufactured by Shandong China Coal Industrial Equipment Corp., Ltd.
Regular inspections for signs of wear or corrosion are recommended, along with ensuring that the arch remains properly secured and aligned during use.
Customization options for lengths may be available; it's best to consult with the manufacturer for specific needs.
The lifespan of the U-channel steel support arch can vary based on environmental conditions and maintenance, but it is designed for long-term use in demanding mining applications.
