3. What is the Steel Block
Cold-drawn special-shaped steel/cold-drawn special-shaped steel has higher precision requirements than simple cross-section steel due to its special and single use, which places higher requirements on the equipment capacity. Due to its complex cross-sectional shape, especially for many special-shaped steels used in specific occasions, there is little experience to learn from, making the hole design and production more difficult than simple cross-section steel.
Therefore, the production cost of special-shaped steel is higher than that of simple cross-section steel. Special-shaped steel has a large difference in shape and size, and many of them are dedicated to a certain industry or specific occasion, so the market demand for a single variety is often not very large. Therefore, the scale of the special-shaped steel production system is often not very large.
