Product Parameters The spiral piles we offer can be customized in various sizes according to your specific requirements. Whether it's for large industrial facilities, small residential buildings, or temporary projects, we can ensure that the size of the spiral piles perfectly matches your project. Through precise size customization, you can maximize the utilization of land resources while ensuring the stability and reliability of the foundation.
Size parameter
• outer diameter: there are a variety of specifications, including 76mm, 89mm, 146mm, which are usually between 60mm-3000mm, and different outer diameter can be applied to different load requirements and conditions. The larger the outer diameter, the stronger the bearing capacity is usually.
• inner diameter: generally between 20mm-2500mm, such as 70mm, the size of the inner diameter will affect the weight and strength of the pile.
• length: the range is usually between 1000mm-3000mm, such as 1200mm, 1500mm, 1800mm, 2000mm, 2000mm, 2200mm, 2500mm, 3000mm, etc., the longer the length, the higher the bearing capacity of the ground pile is generally, which can be selected according to the actual usage scenarios and load requirements.
• wall thickness: generally between 1.0mm-60.0mm, there are 3mm, 4mm, etc. The thicker the wall, the greater the strength and stiffness of the ground pile, and the more corrosion resistance may be.
• spiral pitch: there are 50mm, 75mm, 100mm, 120mm, etc., and the size of the pitch will affect the contact area and friction of the ground pile and the soil, which in turn affects its bearing capacity.
• spiral thickness: generally between 3mm-6mm, such as 3mm, 4mm, 5mm, 6mm, etc., the greater the spiral thickness, the higher the strength of the spiral blade, the more effective load transfer.
• spiral outer diameter: for example, 176mm, 216mm, 250mm, etc., the larger the spiral outer diameter, the larger the contact area with the soil, and the corresponding bearing capacity is improved.
Material parameter
• pile material: steel steel or alloy steel with q235b, q355b, q420 and other materials, which have high strength and toughness and can withstand large loads.
• surface treatment: hot dip galvanizing is the most common surface treatment method. The average thickness of hot dip galvanizing layer is usually between 60 microns to 120 microns, such as 70 microns, 80 microns, 85 microns, etc. Hot dip galvanizing can effectively improve the corrosion resistance of the ground pile and extend its service life.
Performance parameter
• tensile strength: under different geological conditions, the drawing force of spiral pile can bear is different, and generally varies from thousands of cows to dozens of thousands of cows, such as 20kn-30kn in clay, 15kN-20kN in sand, etc., and its size is related to the size, material, surface treatment and geological conditions of ground pile.
• compressive strength: the vertical pressure that can withstand is usually large, and can generally reach dozens of cows to hundreds of thousands of cows or even higher, which enables spiral piles to reliably support various structures.
• shear strength: when subjected to shear force, it can withstand certain shear force to ensure the stability of the connection between the site pile and surrounding soil or rocks, and its value varies with geological conditions and ground pile parameters.
Other parameters
• flange diameter: 200mm, 220mm, etc., flange is used to connect with photovoltaic support or other structures. Its diameter will affect the strength and stability of the connection.
• applicable geological conditions: for example, non-petrochemical soil, clay, gobila, gravel, sand, etc., spiral ground piles of different specifications and materials are suitable for different geological conditions.
• implementation standards: common GB/T 13912, din EN ISO 1461, etc. These standards set out technical requirements for the production, processing, surface treatment of spiral pile to ensure the quality and performance of products.
