Wellmade’s Concrete Tie Rods
Wellmade’s concrete tie rod is also called a tie bar or rebar. It is all thread construction reinforce bars. We produce all types of concrete tie rods. Include discontinuous threaded tie rods and continuous rods. discontinuous thread concrete tie rod is called dywidag bars. It is hot rolled from high strength special steel structure. While the grade of Wellmade’s concrete tie rods includes grade 150, grade 80, grade 100, etc.
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, but with a cheaper cost and price.
As a concrete tie rod manufacturer, we customise your concrete tie rods. You can tell us your construction requirement for the tie rod safety load capacity, Wellmade will custom for you the 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 used sizes. They are working together with the inner threaded tie rod connectors in the concrete construction, like concrete tie couplings, tie rod hex nuts, anchor nut, wing nut, water stopper, formwork cones etc.
According to the threaded types, there are discontinuous dywidag bars and continuous tie bars in Wellmade. Discontinuous concrete tie rods are also called dywidag tie bars, it is hot rolled during tie rod manufacturing. While the continuously threaded rods are cold rolled.
Types of Concrete Tie Rods
1. Dywidag Hot Rolled Tie Bars
Dywidag tie bars are discontinuously threaded rebars. It is a type of hot rolled concrete tie rod. 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 15mm hot-rolled dywidag bars is reaching 201KN. Thus, the dywidag threaded 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.
2. Wellmade 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 an 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.

Welmade Manufactures High-Quality Concrete Tie Rods for Your Construction
No matter you want hot rolled dywidag bars or cold rolled tie rods, Wellmade is able to ensure your tie rods quality.
Wellmade is an ISO9001 and CE-certified formwork and scaffolding tie rod manufacturer. We control the concrete tie rods from steel raw material structure to loading capacity test.
You can find the concrete tie rod mill certificate with chemical composition, steel tensile strength, yield strength, and elongations for each lot of shipment. At the same time, you can get your concrete tie rod order ultimate test result from Wellmade.
With stable and high-quality construction tie rods, Wellmade is famous for supplying the biggest formwork and engineering companies in Germany, the UK, the USA, and other 55 countries globally. Clients use our concrete tie rods for all types of their concrete in civil, industrial, commercial, and infrastructure construction.
Wellmade Concrete Tie Rods Compatible With All Formwork Accessories and Parts
You can use Wellmade concrete tie rods in all types of concrete formwork construction. Including wall formwork, column formwork, slab shuttering, beam formwork, bridge formwork etc. According to construction concrete form tie system requirements, there are M.S (black) steel tie rods and galvanized steel tie bars for your choosing.
In formwork construction, the concrete tie rods are matched with all types of formwork accessories. 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. Engineeringly, the concrete tie bar works like a formwork bolt during the connection in the form tie system.
Concrete Formwork Tie System Wing Nut
As formwork accessories, tie rod wing nut is used very 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 nuts with a round plate are also called concrete anchor nuts. According to the anchor nut wings, there are two wing anchors 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 mould for you.
Concrete Formwork Tie Rod Hex Nut
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 flange type formwork hex nut too.
In the concrete tie rod connector manufacturing, Wellmade produces both drop forged type and cast iron type hex nut. The drop-forged hex nut is weldable. While the cast hex nut is always used for an unweldable tie rod system but cheaper. Both two types of hex nuts are able manufactured at required heights of 15mm, 20mm, 25mm, 30mm, 40mm, 50mm etc. According to the surface finishing, Wellmade’s concrete tie rod hex nut could be in black and galvanized.
Tie Rod For Formwork 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.

The D20 (19/21mm) diameter concrete tie rods is the most buy civil engineering tie rods too. In fabrication, there are dw20 hot rolled and cold rolled types for the D20 tie rod.
For both 16mm and 20mm concrete tie rods, you can get custom lengths. Wellmade helps you cut the concrete tie rod in your length before shipping.
Surface Finishing of Wellmade’s Concrete Tie Rods
As the biggest concrete tie rods manufacturer in China, Wellmade is able to offer black steel(self-finished) tie bars for you. You can also find E-galvanized tie bars here too.
