From the beginning of the last century to the 80s, steel material dominated the rim material, low price, durability, strong load-bearing capacity and other characteristics, so that he is still used today.
Features of steel wheels
1. Stamping production, low cost, convenient processing
2. Absolute load-bearing capacity and hardness are the highest among all rim materials
3. Good toughness, when subjected to more than the maximum external force impact will be deformed, but will not break, sheet metal repair is convenient
