4. What is cold-Formed Section Steel? • Cold-formed section steel is made of cold or hot-rolled strip steels with various of sizes and shapes. • It is characterized with light weight, high strength, structure more reasonable and economical, wide variety, feature smooth surface and accurate size • The steel can be applied to produce section products with uniform thickness and complex cross-section shape which is difficult to be made through the traditional hot-rolled process. • With the reasonable design, its inertia moment of section increases by 1.5-4 times, so that 38-50% of the material steel will be saved compared with hot-rolled sections when it is used in architectural constructions.

5. Comparison between hot and cold- rolled steel

6. Hot-rolled sheet pile Advantages Standard dimension, stable performance, high quality, water-proof, strong durability. Size limits Due to equipments and process limits, the largest width of hot-rolled sheet pile is about 900mm, section modulus is less than 4000cm³. No design flexibility • There are only specified dimensions products in the market. • Too many design margin, difficult to install, sections are too narrow, connections are easily pulled off. It always lead to waste

7. Cold-rolled sheet pile • With the same advantages as hot-rolled pile stable performance, high quality, water-proof, strong durability. • Flexibility, Saving materials Cold-rolled sheet piles have the features of flexible processing and high efficiency. Our products can be processed into any specifications according to the requirement of customs. • Thickness value Cold-rolled sheet pile are no longer thin-walled sheet pile, the largest thickness of sheets can reach 14mm.The thickness value is equal or over the value of hot-rolled sheet piles.. • Connection intensity and watertightness The particular design for locks of our product has high connection intensity and good watertightness.

8. Advantages and strengths

9. Advantages • Our cold-formed piles have advantages as follow: The elements can be prefabricated, which means convenient and economical construction. I The finished product is appealing to the eye. II Meets all the structural safety and environment protection requirements. III

10. Strengths • Reliable clutch mechanisms ensures the complete clutching and provides the effective cut-off from soil and water penetration • Wide profile could reduce clutch joins and installation operations. Easier installation Lower Cost High strength Dependable • Very high strength sections means the piles can retain deep excavations with a minimum of strutting. • With our design, the total quantity of piles could be reduced during constructing.

11. Specifications and samples

12. Specifications Design Considerations OPEN SYSTEMS： As noted, an open system (see Figure) uses ground water from a conventional well as a heat source. ground water is pumped into the heat pump unit, where heat is extracted. Then, the "used" water is released in a stream, pond, ditch, drainage tile, river or lake. This process is often referred to as the "open discharge“ method.

15. We promise B C D A Our cold-formed piles can be used more than 30 times in the natural environment where the bearing capacity is less than 100KN/㎡, such as gravels, sandy, soil and silt. No need of filler when it is installed in clay. Enough operating space could let the construction more efficient. The locks roate 15°freely when they are installed. Structure of locks is atable and reliable There is enough space in the locks, and the connections between piles are simple. Efficiency is twice than the same type of hot-rolled sheet piles ThemeGallery is a Design Digital Content & Contents mall developed by Guild Design Inc.
