Standard taper thread couplers are designed to splice the same diameter bars where one bar can be rotated and the bar is not restricted in its axial direction.It is designed to achieve failure loads in excess of 115% of the characterisitc strength of grade 500 rebar end. Transition taper thread couplers are designed to splice different diameter bars where one bar can be roated and the bar is not restricted in its axial direction. Taper Thread Working Principle: 1.Slice up the end of the rebar; 2.Make the rebar taper thread cut by taper thread machine. 3.Connect together two taper thread end by One piece of Taper Thread Coupler. Taper thread position couplers are designed to quickly splice column sections or precision coupling of elements with multiple bars jointed over a short span, such as prefabricated elements, and the closing of small temporary openings.
With Our Reinforcing Bar Couplers, you will be able to simplify and make it easy for you to install or build reinforced concrete. Our couplers offers precise weight control and higher strength and better quality with its uniform properties throughout the length.
Rebar Couplers simplify the design and construction of reinforced concrete and reduce the amount of reinforcement required.

JIS DC53 tool steel china supplier and stockholders, Otai special Steel are Special steel china suppliers of DC53 steel in round bar, flat bar, sheet , plate and DC53 steel block. we can saw cutting DC53 tool steel as your requirements size. DC53 is improved new type of cold work die steel from SKD11 . The technical specification in Japanese industrial standard JIS G4404. Cold work DC53 tool steel overcomes the insufficient of SKD11 high temperature tempering hardness and toughness of weakness, DC53 tool steel will fully replace SKD11 tool steel in the field of general and precision mould . Its toughness is 2 times of SKD11, DC53 toughness is more prominent in the cold work die. Made of DC53 tools steel rarely appear crack and craze, greatly improving the service life. The DC53 tool steel has a uniform distribution of fine carbides. It has great galling and wear and fatigue resistance. It has also a High temper resistance to support PVD & nitride surface treatments. And it has Machining and grinding properties are superior to most other tool steels. DC53 Form of Supply For Cold work tool steel DC53, we can supply the steel round bar, steel flat bar, steel sheet, plate and square block. DC53 tool steel round bar can be sawn to your required length and size. Rectangular steel pieces can be sawn from flat bar or plate to your specific sizes. Ground tool steel bar can be supplied, providing a quality precision finished bar to tight tolerances. DC53 steel Applications The Cold work DC53 Tool Steel is found in Punches & dies, Draw & forum dies, Shear blades, Shredder knives, Thread & form rolls, Cold heading dies and Mill rolls & slitters. Heat treatment JIS DC53 steel The DC53 Tool steel heat treatment process can be broken down into 4 segments, Hardening (quench) & Tempering.Annealing & Normalized. Most customers only need make the Hardening (quench) & Tempering for DC53 steel aplication. JIS DC53 tool steel Forging Slowly and uniformly Heat the DC53 tool steel to 700°C (1292°F),then rapidly heat the DC53 steel to 900-1040°C(1652-1904°F). After forging slowly cool down. DC53 tool steel Hardening | quenching Heat slowly the DC53 tool steel to 850°C(1562°F), Soak thoroughly at the temperature. the brought up to 1030°C(1886°F)oil quenching or air cool.
