Description of T76N threaded Mai bar:
Chinese manufacturer of T76N threaded Mai bar
Feature
ONTON® Drill Hollow Bar (Self Drilling Anchor, SDA) features a wide range of applications such as soil nails, micropiles, rock bolts, or ground anchors. It is applied to self-drilling ground control solution used in Civil Engineering and underground construction.
Applications
Civil Engineering Underground Mining and Tunneling 1. Pile foundation 1. Stabilization of tunnel portals,
trenches, and cut-and-cover areas2. Slope and embankment stabilization 2. Forepoling 3. Reinforcement of excavation pits and
retaining walls3. Face stabilization 4. Foundation of pylons and wind mills 4. Radial rock bolting 5. Anchorage of avalanche protection
structures and noise barriers5. Roof and rib bolting 6. Injection works 6. Injection works SDA (IBO) is a kind of safety product.
Safe products is the most important thing of engineering safety.
We only produce safe products.
Security is not just lip service.
Established in the early 1990s.

FAQ:
1. Products standards:
'EU Construction Products Directive': EN 14199:2005 Micropiles and EN 14490:2010 Soil Nails.
2. What the EU standards require?
EN 14199:2005 "Micropiles", clause 6.2.1 and EN 14490:2010 "Soil Nails", clause 6.2.2.2 require:
Yield Stress, fyk, between 400 to 600 MPa (60 to 87 ksi)
Ductility (Elongation Agt > 5% required by EN 10080, ASASTM A615 , ASASTM A370)
All the required properties above are tested of Finished hollow-bar, NOT raw materials.
3. What is Agt?
Agt denotes the elongation up to ultimate load without reduction of cross-section.
It is not to be confused with total elongation, A, up to rupture.
Usually elongation, A, has double the value of Agt.
4. What is the standard of quality for SDA? Is the higher the strength, the better?
No, the grade of material strength is based on its yield strength. However, for the Grade of Product Quality, the key index should be its ductility (i.e. the values of Agt and Rm/Rp0.2, according to Eurocode EC2).
