As REGNUM, we offer the best products, services and support that best fit to your needs of Dowel Bar. We produce epoxy coated, galvanized, stainless Dowel Bars.
Dowel Bars are placed in the transverse joints of the concrete floor and they play a part in the transfer of partial shear load from a floor to adjacent floor. Dowel Bar also allows axial thermal expansion and contraction of the concrete slab along the shear axis.
Half of the length of this bar is embedded in one of the concrete slabs and the rest is adhered to the adjacent slab. One end of the rod is kept free for movement during expansion and contraction of the slab depending on temperature change.
Dowel Bar is used to transfer the load from one slab to other, while allowing axial thermal expansion along the shaft axis. Stainless Dowel Bar is usually made of flat round material. They offer a corrosion-resistant solution that is resistant to connections in concrete or other structural applications. Dowel Bars suitable for most requirements in material categories and strengths are available.
Carbon Steel: ASTM A615 / 615M: Gr40 、 Gr60 / Gr75
Stainless steel: 304 / 304L 75 316 / 316L 、 S31803 M S32205 A S32304
Placing Dowel Bars
They always should be parallel to the center line.
New channels must be cut so that at least half of the anchor can be on either side of the joint or crack.
Dowel Bars significantly improve the performance of sidewalk connections
Although they increase the initial cost, they reduce the Life Cycle Cost.
Dowel Bars are short steel bars that provide a mechanical connection between slabs without restricting horizontal joint movement. Before passing over the load, they make the release plate take on some of the load and increase the efficiency of load transfer. This reduces joint deviation and stress in the approach and dispersion slabs.
Epoxy-Coated Dowel Bars protect by using various mechanisms. Epoxy-Coated Dowel Bars have shown that the corrosion rates of Steel Reinforcement Rods is 40 to 50 times lower than similar uncoated bars.
Epoxy Coated rebar can be used in any concrete that is exposed to corrosive conditions. These may include exposure to de-icing salts or seawater.
