Steel Chemistry
A combination of steel grades is used and heat treatment processes to manufacture soft, medium and hard tensile grades. The table below is indicative only of steel chemistries used.
| Tensile Grade | % Carbon | % Phosphorus | % Manganese | % Silicon | % Sulphur |
| Standard | 0.45~0.50 | 0.032 | 0.5 ~1.00 | 0.10~0.34 | 0.041 |
| High | 0.59~0.63 | 0.035 | 0.5 ~1.10 | 0.10~0.35 | 0.045 |
| Extra-High | 0.65~0.83 | 0.035 | 0.5 ~1.10 | 0.10~0.35 | 0.045 |
Quality Control:
We use total quality control system. Every pieces of the raw material; semi-finished products and finished products are tested and recorded in file. The tracking record is used from final products to the very first beginning raw material steel factories.
Third Part like SGS is available for test control before shipment
Packing:
1) All the products are packed with seaworthy packing.
2) Customer’s special requirement for packing can be satisfied.
3) Air freight; sea freight and truck freight are all available.
