Cold formed steel sheet pile, also known as cold formed sheet pile, is made from steel coils that are passed through different rolls at ambient temperature. Due to their light weight and high cross-sectional modulus, cold-formed profiles are widely used all over the world.

 

We have different types of cold formed steel sheet piles in our catalog, U-shaped sheet piles and Z-shaped sheet piles. We can offer all steel grades and properties. The most widely used standards are EN 10249-1 and EN 10249-2. Steel grades are S235 JRC, S275 JRC, S355 JOC or others. In North America, construction companies and traders follow ASTM A328 and 328M standards. In many countries, cold formed sheet piles are used for almost all types of projects. In the Philippines, for example, cold formed sheet piles can be found everywhere in Manila, Cebu, Davao, Batangas, General Santos, Cagayan de Oro, etc. Metal interlocking sheet piles, also known as piling sheets or Australian sheet piles, can be made into sheet pile foundations and mined at a lower price.

 

In many temporary projects, such as bridge piers and abutments, canals, and excavations, you can use cold rolled sections. In permanent applications, such as deep foundations, containment, tunnels, environments, you can also find cold rolled profiles. Cold forming has created many innovations in the pile industry, such as wider, deeper, and multi-thickness sections. This is a great advantage for design houses and customers. Cold-formed sheet piles were introduced more than thirty years ago. There are now more than a dozen plants worldwide producing cold-formed sheet piles compared to the six hot-rolled plants worldwide.

 

Special shapes and sizes of sheet piles are manufactured to meet the requirements of joints and other similar situations. In fact, cold formed piles never have the tendency to break away from the interlock as many hot rolled steel sheets do under difficult driving conditions. When you have a cofferdam, retaining wall, parking lot, or bulkhead project, you can contact us.

Hot rolled steel sheet piles are made from hot steel billets that have been gradually shaped and interlocked during the forming process. Hot rolled interlocks tend to be tighter and have better water resistance.

 

Hot rolled steel sheet piles can be classified by profile and size: U- and Z-shape. Hot rolled profiles can achieve very high modulus by connecting steel tubes, oversized piles or other sheet piles. Tubular combination walls are sheet piles and steel tubes connected by C9 or C6 interlocking devices. hz and hzm oversized piles can also be connected by RZD, RZU, RH 16 and 18 joints. Sheet piles can also be formed as box sheet piles.

 

Hoesch sheet piles are also interlocking sheet piles, including AU, PU, GU, Larssen profiles, VL sizes, AZ sizes, AS sizes, etc.

 

There are many steel grades for hot rolled sheet piles: in EN 10248 there are S240GP, S270GP, S320GP, S355GP, S390GP, S430GP, S460AP steel grades. Recently, there are corrosion resistant steel grades for marine applications: MLoCor Blue 320, Blue355, Blue390. american ASTM standards have A36, A 328, A572 grade 42/50/55/60/65, A588 and marine grade A690. in Japan, JIS A 5523 and JIS A 5528 standards have SY295, SY390, SYW295, SYW390.

Steel sheet pile can be divided into cold-formed thin-wall steel sheet pile and hot rolled steel sheet pile according to production technology. In engineering construction, the application scope of cold-formed steel sheet pile is narrow, and it is mostly used as material supplement, while hot-rolled steel sheet pile is always the leading product in engineering application. Based on the advantages of steel sheet pile in construction, the State General Administration of Quality Supervision, Inspection and Quarantine and Standardization Administration issued the “Hot Rolled U-Shaped Steel Sheet Pile” national standard on May 14, 2007, and was formally implemented on December 1, 2007. At the end of the 20th century, Masteel Co., LTD., with the technology and equipment of universal rolling mill production line imported from abroad, produced more than 5,000 tons of 400mm U-shaped steel sheet piles, which were successfully used in the Nenjiang Bridge cofferdam, the 300,000-ton dock of Jingjiang New Century Shipyard and flood control projects in Bangladesh. However, due to low production efficiency, poor economic benefits, little domestic demand and lack of technical experience during the trial production, the production failed to continue. According to statistics, at present, the annual consumption of steel plate pile in China remains at 30,000 tons, only 1%% in the world, and is limited to the permanent engineering of some ports, docks, shipyard construction and other temporary engineering of building bridge cofferdam, foundation pit supporting.
