Core Size & Weight Chart
Select the type of material for which the "In Place" weight data is
required. The tables show the weight in kilograms per linear metre
for each common core diameter. The last column provides the weight
of a cubic metre of each given material. The nominal densities in
gm/cc for each type of material are also shown in the second
column.
Features:
Available in all standard drilling sizes (BTW,NTW,HTW).
Heat treated and anti-rust coating process
High straightness and concentricity
Superior performance:
Drill rods and casing are quality-crafted in standard sizes using
superior alloy steel, with each end of the rodsheat-treated for
greater wear resistance. Drill rods and casing also provides a
tight mechanical seal. Developed to meet or surpass the performance
of any similar product, the superiority of drill rods has been
confirmed in actual surface and underground drilling field test
operations.
Reasonableprocess:
Our products feature an anti-rust coating and are ready for
drilling. Each thread is lubricated and protected using recyclable
cardboard packaging and steel caps. In order to reduce
environmental impact, packaging for drill rods and casing is
entirely recyclable and does not contain any plastic.
