Dynamic load (D)
| Intensity level | Static load | Size range | Dynamic load | Size range |
| Low tensile strength | SL | 1.0-10 | - | - |
| Medium tensile strength | SM | 0.3-13 | DM | 0.08-13 |
| High tensile strength | SH | 0.3-13 | DH | 0.05-13 |
3. Surafce condition:
Smooth steel wire and coated steel wire.
4. Circle shape of wire:
The steel wire should have a uniform and regular loop shape. After
the lashing wire is cut, the free circle diameter of the steel wire
should not be less than the coil diameter of the steel wire, and
the ring shape enlargement phenomenon is allowed, but the
enlargement degree should be roughly uniform in the same coil and
uniform batch of steel wires.
5. Surface quality
The surface of the steel wire should be smooth, and there should be
no surface defects such as pull marks, tears, rust, etc. that have
obvious adverse effects on the use of the steel wire.
6. f- circle distance, (mm);
D- free circle diameter, ( mm);
d- the nominal diameter of the steel wire, (mm);
7.Picture show:
100% of our steel tubes are dimensionally checked
100% of our steel tubes are visually checked to assure they have a
perfect surface condition and no surface defects.
100% eddy current test and ultrosonic test to eliminate
longitudinal and transversal defects.
QUALITY CONTROL:
1. Incoming Raw Material Inspection
2. Raw Material Segregation to avoid steel grade mix-up
3. Heating and Hammering End for Cold Drawing
4. Cold Drawing and Cold Rolling, on line inspection
5. Heat Treatment, +A, +SRA, +LC, +N, Q+T
6. Straightening-Cutting to specified length-Finished Measuring
Inspection
7. Machanical Testing in own labs with Tensile Strength, Yield
Strength, Elongation, Hardness, Impact, Mictrostruture etc
8. Packing and Stocking
