Cold-bent steel sheet pile is manufactured of hot (cold) rolled strip steel which passes though several pairs of forming blocks composed of forming roller sheet of different shapes and is formed through continuous roll-type bending process so as to achieve various sectional forms for various required steel sheet piles.
GP series cold-bent steel sheet pile products have the following characteristics:
(1)Thanks to the fact that cold-bent steel sheet pile is made of hot-rolled strip steel through continuous compaction, the design of sectional structure is provided with high flexibility for production of products with large section, small and equal wall thickness;
(2)GP series cold-bent steel sheet pile is suitable for large sized products with effective width, height and thickness not more than 16mm, having conformed(adapted) to the development trend of the world's cold-bent steel sheet pile products and satisfied the requirements of engineering application of cold-bent steel sheet pile;
(3)The maximum section modulus of U-mode products of GP series cold-bent steel sheet pile is up to 4260 cm3/m2, and that of Z-mode series is up to 5100 cm3/m2; Thanks to the rational section structure design and the state-of-art forming technology of GP series;
(4)cold-bent steel sheet pile, the ratio of section modulus to product weight (also known as "mass coefficient") has been increasing continuously. This contributes to better economic benefit of application and broadens the application area of cold-bent steel sheet pile;
The use of large-sized cold-bent steel sheet pile facilitates the reduction of working load of pile sinking(driving) , the improvement of work efficiency and the reduction in quantity of water seal joints.
