1. Small section steel: The production and processing of the middle angle, round, square, and flat steel of the small section steel is similar to that of the large-scale use, and the small-diameter round can be used to build steel bars. Special-shaped steels include retaining ring, horseshoe steel, magnetic pole steel, presser foot plate, shallow channel steel, small channel steel, T-shaped steel, ball flat steel, feeding tooth steel, hot-rolled hexagonal steel, etc. Others include rivet steel, tiller steel, and window frame steel.

2. Medium-sized steel: Medium-sized steel is similar to medium-sized steel, slot, angle, round and flat steel. There are also special steel used for making agricultural machinery ploughs, elevator guide rails, wheel net steel that can be used in automobile wheel nets, and composite flat steel for small tillers used to create tillers.

3. Large section steel: large-scale medium I-beam, channel steel, angle steel, flat steel are hot rolled, round steel, square steel, hexagonal steel in addition to hot rolling, forging, cold drawing, etc. Steel piles are used for water conservancy construction or mining projects. These special-shaped steels can be used for the shape and dimensions of parts or products, which can greatly reduce mechanical processing, ensure products, and save metals.
