steel bars with industrial standard production process called(Electric Arc Furnace) EAF



 
 


 How to select the good quality steel bars
1. steel Skin
- Round bars: the skin should be smooth with round diameter
- Deformed bars: the pitch should be equal across the bar
2. Size and correct diameter and more importantly the weight that matches with the specification 
3. Has ability to bend without jeopardizing the bars
4. The rust on the skin is rather common in SEA where atmosphere is humid and hot, however there shouldn't be the rust deep down inside the bars
 
 
Each bar is inspected for its chemical structure and passed through many mechanical tests ranging from tensile to cold bend testing. Our products are conformed to TIS Standard 20-2543 and 24-2548. We can guarantee to maintain consistent quality production and distribution in the following products:
1. Round Bar (Grade SR24): 6, 9, 12, 15, 19, and 25mm.
2. Deformed Bar (Grade SD30, SD40, and SD50) : 10, 12, 16, 20, 25, 28, 32, and 40mm.
3. Square Bar : 12, 16, 19mm.
