The duplex coating self drilling anchor introduce two corrosion-prevention measurements on the rod surface,hot-dip galvanizing and epoxy coating,which can avoid corrosion to a large extent.

It is largely used to geological conditions which are influenced by uderground water such as road,raily,tunnel and subsea tunnel and which are erroded by seawater such as harbor,wharf and bulidings on the band affected.

Features:

1.Thick-hot-dip galvanizing coating,great combination,high anti-corrosion and good toughness.

2.Benefits of epoxy coating:

1)High adhesive force to the steel substrate.

2)Excellent physical properties and chemical stability.

3)Excellent toughness and wear resistance.

4)A wide range of tempreture adaptability.

5)Fine insulation and resisting anode dissolution.

3.Its anti-corrosion of the combination of two methods can keep more than 100 years.

In order to connect self drilling hollow anchor bar to drill rig,shank adapter is usually installed under hammer drive for transfering torsion.

Features:

1.The product made of thick-wall steel pipe is dealt with maching and heat treatment.It is applied to high wear resistance conditions.

2.When using the reducing shank adapter,it is necessary to increase the locking torque at the large diameter end to prevent the anchor bar climbing into the chamber of large diameter.

3.Normally,expanding shank adapter of self drilling anchor bar is not recommended.

4.Shank adapter is light,it's weight is only a quarter of rebar with the same specifications.It is easier for construction and can reduce workers'labor intensity.

5.Shank adapter is of high corrosion resistance quality.It can be used in low PH ground conditions.
