Steel and Rebar Tensile Testing
MATLAB Materials Laboratory provides mechanical testing of steel in Cambodia: tensile, yield, elongation and bend tests on reinforcing bar from 6 to 50 mm, proof and tensile tests on mechanical couplers and prestressing strand, tensile and shear tests on anchor and connection bolts, and tensile tests on plate, tube and rolled sections.
Results are reported against the grade your project specifies, whether ASTM A615, ISO 15630-1, JIS or GB/T, so a rebar delivery from any supplier can be accepted or rejected on the same day the samples arrive. Weld quality and installed steelwork are inspected on site by our NDT team.



Reinforcement and strand
| Test | Method |
|---|---|
| Rebar tensile, 6 to 50 mm | ASTM A370 / ISO 15630-1 |
| Yield, tensile strength, elongation | ASTM A370 / A615 |
| Bend and re-bend test | ASTM A370 / ISO 15630-1 |
| Mechanical coupler and welded joint | ISO 15835 / ASTM A1034 |
| Seven-wire strand, 12.7 to 15.6 mm | ASTM A1061 / A416 |
Bolts and structural steel
| Test | Method |
|---|---|

| Single shear test of bolt | ASTM F606 |
| Plate, tube, I/H/C-section tensile | ASTM A370 / ISO 6892-1 |
| Galvanised steel tensile | ASTM A370 / ISO 6892-1 |
| Torque wrench calibration | ISO 6789 |
Who uses this service
Contractors verifying rebar deliveries per batch, steel traders and importers certifying stock, precast and prestressing yards, and structural consultants accepting couplers and anchors.
How it works
- Quotation: send the specification clause or test list; the quotation names each standard and unit price.
- Sampling: deliver samples to #271, Street 1964, Sen Sok, Phnom Penh, or book our crew for site sampling anywhere in Cambodia.
- Testing and report: tests are run to the named method and the signed report is issued on completion, with results against the specified limits.
Why contractors and consultants choose MATLAB
- MLMUPC General Construction Laboratory License No. 0001 and CANC-registered conformity assessment body.
- Rebar from 6 to 50 mm, strand 12.7 to 15.6 mm, bolts and structural sections on one price schedule.
- Every quotation names the standard and unit price; batch testing rates for repeat deliveries.
- Torque wrench calibration to ISO 6789 for bolting crews.
Frequently asked questions
How many rebar samples are needed per delivery?
Most specifications call for one set of samples per bar size per heat number or per defined tonnage. Send us the specification clause and we will confirm the sampling plan and price.
What does a rebar tensile test report show?
Yield strength, ultimate tensile strength, elongation and the yield-to-tensile ratio, compared with the grade limits of ASTM A615, ISO 15630-1 or the standard you nominate, plus the bend or re-bend result.
Do you test mechanical couplers?
Yes, to ISO 15835 or ASTM A1034, including tensile tests on spliced bars.
Can you test anchor bolts and structural bolts?
Yes: anchor bolt tensile with and without nut, connection bolt tensile and single shear to ASTM F606 and F3125.
