Sheet Piles Z-type Sheet Piles U-type 
Sheet Piles are by definition, structural units which when connected one to another, will form a continuous wall, generally for retaining earth or excluding water. Individual pieces or pre-interlocked pairs are installed by driving them into the earth using impact hammers, vibrators or by water jetting. In functioning as a wall, the sheet piling acts as a beam under load and therefore requires the capability to resist bending. In certain applications, ability to resist bending is not important but strength of interlock is.
Sheet Piling is manufactured in three basic configurations "Z", "U", and "Straight". They can be formed either "Hot Rolled" or "Cold Rolled". A recent development to the industry is the production of some sheet piling shapes by the cold-forming process in which hot rolled sheet is fabricated into traditional sheet piling shapes. These new additions to product availability contain interlocks which are considerably different from the hot-rolled product. Manufactured from a hot-rolled coil of sheet, it is slowly fed through a series of rollers which gradually bends or forms the steel into its designated shape. Sheet Piles manufactured through cold forming process attain better physical properties and dimensional tolerances than compared to that manufactured by hot process. Apart from the advantage of higher section modulus, moment of inertia and sectional area per meter of wall there is advantage of 20% weight as well.
The "Z" type configuration for sheet piling is the strongest and most efficient. These shapes resemble wide-flange beams, having a web and two flanges. Since the interlocks are located out on the flanges at maximum distance from the neutral axis, a higher section modulus for resisting bending moments is provided. Z-Shapes have traditionally been used for deeper walls and heavier construction projects. However, they are now supplanting the arch or "U" shape for lighter work as more light-weight Z-shape have been introduced into the marketplace.
U-shapes resemble the hot-rolled channel sections produced on structural mills. The interlocks are formed on the web ends and interlock with their opposing mate along the centerline of the wall.

Steel Shot
Steel Shot is manfactured from electric melted basic Steel with a minimum carbon content of 0.85% cast by an exclusive process and then heat treated to a tempered martensitic micro structure.
Average hardness provided is 400-500 VPN (about 40-48 Rockwell C) as this hardness has generally been proved to be ideal for efficient and economic blast cleaning operations. special hardness can, however, be tailored upon request.
The exclusive casting process ensures that the Shot is perfectly spherical, free from 'Fish-tails' and hollows, the density of the shot being over 7.3 grams/cc.
Advantages
RESISTANCE TO BREAK-DOWN-Ten or more times that of iron shot. Two or more times that of malleable shot.
REDUCES MACHINE MAINTENANCE EXPENSE-up to 50% or more.
MORE ATTRACTIVE FINISH-Leaves no carbon deposit or metallic residue or imbedment.
Reduces storage, handling, freight, dust disposal expense.

Steel Grit
Steel Grit is manufactured from solid Steel Shot by fragmenting it into sharp angular grit. Thus the steel grit is a product of the same tough resilient steel as our Steel Shot. It is heat-treated also to yield a product consistent with the ideal quality requirements.
