(Presseportal openBroadcast) - Hollow bars are produced under strict quality control in two types of thread profiles:
1. Standard Thread: conforms to ISO, UNC or DIN standards. Rolled thread is known as the
stronger thread than conventional cut one.
2. Thread Bar: is manufactured under Thai Industrial Standard (TIS). This special type of
thread is the special coarse thread. Its big advantage is that customers can cut and connect
it anywhere just by a coupler and a nut.
Hollow bars are available in size Ø16 mm, 20 mm, 25 mm, 28 mm, 32 mm, and 40 mm. The full standard lengths are 10 and 12 meters. The longer
lengthcan be obtained by using mechanical connector (coupler).
Hollow bar can be protected from corrosion by various means such as hot-dip galvanized,
epoxy coated or as specified.
The features of Sinorock hollow anchor bar By using expansion shell prestressing
self drilling hollow bar,screw the anchor nut or expand equipments to transfer tension load
to earth mass,and the spherical and taper area at the bottom of hollow anchor bar will be
obviously increased. The well can stable unconsolidable ground conditions or increase the
shearing strength of sliding surface. Arranging expansion shell anchor bolt or self drilling
hollow anchor bar according to a certain space,which can change surrouding rock into
protection lines to strengthen tunnel and slope support project. The self drilling hollow
anchor bar combines drill bolt and hollow rod together and it is widely used in various
engineering conditions including weak rock,loose soil,decayed rocks and unconsolidable earth
mass and so on.
The hollow anchor bar ,which is one of the leading anchoring products of Sinorock,and has
been extensively applied in the mine,tunnel,foundation support project,hydroelectric support
project and slope stablization.More from http://www.hollowbar.org/
