Hot Rolled Steel Sheet Piles
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.
