Wellmade’s Concrete Tie Rods
If you are seeking tie rods for your concrete formwork. Wellmade will be your best choice. We manufacture all types of concrete tie rods to meet up your different construction requirements. In fabrication, there are high-grade concrete tie rods in steel grade 900/1100. We also have concrete tie rods in S450 and S235, which are in lower steel-grade than 900/1100 dywidag rebars. You can tell us your safety load capacity requirement, Wellmade will custom your concrete tie rods and bars according to the actual concrete tie rods test result.
We custom your concrete tie rod sizes too. You can find the steel threaded rods in diameter from 6mm to 32mm here. Among all of them, d15mm, d16mm, and d20mm sizes of tie rods are widely using. They are working together with the inner threaded concrete tie rod couplings, nuts, and cones in construction.
According to the threaded types, there are discontinuous dywidag bars and continuous tie bars in Wellmade.
Dywidag Hot Rolled Tie Bars
Dywidag tie bars are discontinuously threaded rebars. It is a type of hot rolled concrete tie rods. According to the sizes, there are 6# to 28# dywidag bars. Among the hot-rolled dywidag tie rod, the sizes of dw 15 and dw20 are the most popular sizes.
Wellmade’s dywidag type concrete tie rods are made from 830 and 930 steel grades. The ultimate load of the hot-rolled dywidag bars is reaching 201KN. Thus, the Dywidag concrete tie rod is also called heavy load capacity construction rebar.
Discontinuous threaded make the concrete tie rods self-cleaning in construction after working from the concreting.
Wellmade’s Cold Rolled Tie Rods
Compare to hot rolled dywidag bars, the cold-rolled concrete tie rods are threaded from a steel round bar structure. According to the steel grade, Wellmade supplies your S235, S450, and 42CrMo cold roll steel coil rods for your construction.
The different steel structure grade brings your different grade of concrete tie rods. Take D16(15/17mm) sizes for example:
- S235 steel grade D16 concrete tie rods ultimate test result: 95KN
- S450 steel grade D16 tie rod: the maximum load is 145KN
- 42CrMo steel grade tie rod in 16mm: load capacity can reach 190KN
The cold-rolled concrete tie rods are at a lower cost and cheaper price than the dywidag hot rolled tie bars. Thus, this type of tie rods is used popularly in normal civil and commercial constructions. In the other words, the hot-rolled dywidag tie rods are expected heavier and bigger breaking loads.

Wellmade’s concrete tie rods working with all formwork accessories and parts
The concrete tie rods are using with formwork accessories in concrete construction. Wellmade tie rods and bars are able to work with formwork wing nuts, concrete anchor nut, hex nuts,formwork wedge clamps, rapid clamps(spring clamp), water stopper, dome plate combi nut, form ties, steel & plastic (PVC) cones, etc. While, in the form tie system, the concrete tie rods are able to work with both D Cones and P cones.
Formwork Wing Nut for Concrete Tie Rods
As formwork accessories, tie rod wing nut is used frequently. Formwork wing nuts include wing nuts without round plates and wing nuts with round plates.
If you using a wing nut without a round plate, a waler plate is applied during your concrete pour shuttering.
Formwork wing nut with a round plate is also called concrete anchor nut. According to the anchor nut wings, there are two wing anchor and three wing anchor accessories for your concrete tie rod construction.
According to the formwork anchor nut round plate diameters, you can find from Wellmade D60mm, D70mm, D80mm, D90mm, D100mm, D110mm, D120mm, D130mm anchor nuts. If you have any other special shapes and dimensions of formwork anchor nuts, Wellmade is able to open a new mold for you.
Formwork Hex Nut for Concrete Tie Rods
Hex nuts work as formwork coupling during the construction shuttering. According to the height of the formwork hex nut, there is a 30mm to 120mm hex nut for your choosing. You can ask the formwork hex nut with flanges too.
In manufacturing, Wellmade produces both drop forged type and cast iron type hex nut. While the drop-forged hex nut is weldable and cast hex nut is always used for an unweldable tie rod system. Both types of hex nuts are able to manufacture at all required heights. According to the surface finishing, Wellmade’s concrete tie rod hex nut could be in black and galvanized.
Tie Rod Combi Nut
Formwork combi nut is a combination formwork accessory with wing nut and waler plates. You can find drop forged type and cast type combi nuts in Wellmade. According to the shape of the waler plates, there are round type and square type combination dome nuts for your choosing.
