ASTM A536 65-45-12 Ductile Iron Castings is a ductile iron casting specification that offers high strength, ductility, and impact resistance. This specification describes a specific grade of ductile iron that contains 65,000 psi minimum tensile strength, 45,000 psi minimum yield strength, and 12% minimum elongation.

Prestressed Unboned PC Mono Strand Anchor is a specific type of anchorage system used in prestressed concrete construction. It is commonly used in applications such as bridges, beams, and slabs.

You can rest assured to buy Bonded Post-Tensioning System Anchor from our factory. Bonded Post-Tensioning comprises tendons from one to multiple strands (multistrand) or bars. For bonded systems, the prestressing steel is encased in a corrugated metal or plastic duct. After the tendon is stressed, cementitious grout is injected into the duct to bond it to the surrounding concrete. Besides, the grout creates an alkaline environment which provides corrosion protection for the prestressing steel. Bonded multi-strand systems, while used extensively in new construction of bridges and transportation structures, can be and have been successfully applied to commercial building structures. When these multi-strand systems are used for large structural elements such as beams and transfer girders, design advantages include increased span lengths and load carrying capacity and reduced deflection.

The ductile cast iron truck engine cylinder block is one central part of the engine in an automobile. The engine block structure contains the cylinders and other engine parts of an internal combustion engine. It is also called an Engine Block.

The Underground expansion shell holds in any rock strata which is sufficiently competent to provide an adequate anchorage. They are designed to anchor in soft ground or hard rock. In good strata, the anchorage exceeds the ultimate strength of the steel bolt. All expansion shells require a competent strata in the anchor zone.
