Standard Aluminum Inclinometer Casing
GT-AL-00 is the standard OD 70 mm aluminium inclinometer casing, built to the same groove and straightness specification as our ABS and PVC casing. It is supplied in 3 m or 2 m lengths with 76 mm couplings and is the choice where a stiffer casing is wanted in the monitored zone.
ISO 9001:2015 production Samples available Small orders accepted
Product Overview
GT-AL-00 is the standard OD 70 mm aluminium inclinometer casing, built to the same groove and straightness specification as our ABS and PVC casing. It is supplied in 3 m or 2 m lengths with 76 mm couplings and is the choice where a stiffer casing is wanted in the monitored zone.
Materials
- Aluminium
Key Benefits
- Metal casing for installations where stiffness and handling strength matter
- Groove geometry identical to our ABS and PVC casing, so probes and couplings interchange
- Bending 1.0 per mille or less and torsion 0.2 degrees per metre or less
- Intensity strength at least 1200 N/100m on casing and coupling
- Available alongside ABS and PVC from the same supplier and the same delivery schedule
Application Scenarios And Who It Is For
Application Scenarios
- Boreholes where casing will take rough handling during installation
- Monitoring in zones subject to high ground pressure
- Installations where a stiffer casing is specified by the designer
- Projects mixing materials by depth zone
Who It Is For
- Consultants specifying metal casing for demanding zones
- Monitoring contractors working in hard or high-stress ground
- Drilling contractors installing deep survey casing
- Distributors covering the full casing range
Problems It Solves
- Plastic casing deforming under high ground stress in the monitored zone
- Handling damage on long installations in difficult access
- Mixing suppliers when a project calls for more than one casing material
- Maintaining a single groove standard across mixed material strings
Technical Features
- Aluminium casing OD 70 plus minus 1.0 mm with wall thickness 5 plus minus 0.5 mm
- Guide groove 5 plus minus 0.5 mm wide and 2 plus minus 0.2 mm deep
- Bending 1.0 per mille or less, torsion 0.2 degrees per metre or less, radian 0.4 mm or less
- Coupling OD 76 plus minus 1.0 mm, wall 5 plus minus 0.5 mm, length 18 plus minus 0.5 cm
- Intensity strength at least 1200 N/100m and heat deflection temperature at least 97 degrees C

Quality Control
- Outer diameter held to plus minus 1.0 mm on casing and to the stated tolerance on couplings
- Groove width and depth checked so probe wheels track without binding
- Bending, torsion angle and radian measured on production lengths
- Intensity strength and heat deflection temperature verified against the published limits
Customization Options
- Casing length 3 m or 2 m
- Caps, protection boxes and couplings
- Mixed material strings across depth zones
Comparison With Other Products
| Compared With | Why This Product |
|---|---|
| Standard ABS Inclinometer Casing | Aluminium is stiffer and takes rougher handling; ABS is lighter and the usual routine choice |
| Standard PVC Inclinometer Casing | Same dimensional specification, different material stiffness |
Use Guide
- Check groove alignment between lengths before lowering the string into the hole
- Join lengths with the matching couplings and seal against grout ingress
- Set one groove pair along the expected direction of movement and record the orientation
- Fit top and bottom caps, and a protection box where the casing head is exposed
Questions Buyers Ask
Standard Aluminum Inclinometer Casing FAQ
What tolerance do you hold on the casing
OD 70 plus minus 1.0 mm, wall thickness 5 plus minus 0.5 mm, groove width 5 plus minus 0.5 mm and groove depth 2 plus minus 0.2 mm.
How straight is the casing
Bending is 1.0 per mille or less, torsion angle 0.2 degrees per metre or less and radian 0.4 mm or less.
What is the production capacity
Two extrusion lines can produce tens of thousands of metres of casing or pipe each day, so long orders do not wait behind short ones.
Is the quality system certified
The company is approved to ISO 9001:2015, which keeps casing production traceable.
Do you supply caps and protection boxes
Yes. Top and bottom caps and outer protection boxes are available as optional parts for inclinometer casings.
Can you ship a mixed order of casing and instruments
Yes. Send your casing metres and instrument list on WhatsApp and we will quote them together.
