Hot- rolled products are made from slabs which are reheated in the reheating furnaces, rolled in the roughing mill and the finishing mill, cooled in the laminar spray way, down coiled into hot bands, and delivered to the hot-rolled finishing mill for skin pass, crop shearing, inspection, weighing, packaging, and marking. Presently, the types of hot-rolled products Supplies are hot-rolled bands(or hot-rolled coils,non-skinpassed), hot-rolled coils, hot rolled plates, hot rolled sheets, and hot-rolled pickled and oiled coil.
The available sizes are 1.20~5.99mm in thickness for hot-rolled sheets, 1.20~6.50mm for hot-rolled coils,hot- rolled pickled and oiled coils, 2.00~12.7mm for hot-rolled bands, 6.00~12.7mm for hot-rolled plates,and 850~1,860mm in width for all types except hot-rolled pickled and oiled coils which range between 860~1,540mm.

The annual production capacity is 1.8 million tons with the available sizes of 0.30~3.20mm in thickness,850~1,650mm in width for carbon steel, and 0.55~1.60mm in thickness, 850~1,260 in width for high strength low alloy steel.
The following are the distinguishing features and application of cold-rolled products:
1. Luster: CQZ and DQ with bright and fine luster can be used as fundamental materials in producing automobile body parts, and home appliances which demand excellent appearance quality.
2. Diversity and mechanical uniformity: CQS can be used in producing steel drums, and CQ1 in producing piping. SPCE( extra deep drawing mild steel) can be used in producing automobile parts which demand strict processing. High strength steel can be used in producing structures or reinforcing parts.
3. Expansibility: After cold rolled products are processed, they can be further treated with heat, e.g. carburization or nitrocarburization, to make their surfaces hardened and more abrasion resistant.

Both steel bars and wire rods are rolled from reheated billets. Supplies bars in two forms, namely straight bars and bars in coils, with the available nominal diameters from 5.5mm to 13mm for straight bars and from 14mm to 55mm for bars in coils.The rods are in a coil form only, with the available nominal diameters from 5.5mm to 13mm.The total annual production for both is around 1.77 million tons, of which the product assortmentsare 35% for low carbon steel, 18% for medium high carbon steel, 26% for cold heading steel, and 21% for low alloy steel. By the application of different processing techniques, steel bars and wire rods can be used for manufacturing general structures, machine structures, hard wires, and weld electrodes, and so on; they are also ideal materials for products which demand cold heading processing and hot forging processing

1 million tons of plates are produced annually with the dimensions of 6 to 90mm in thickness, 1524 to 3800mm in width, and 3048 to 18000mm in length.plates are used in manufacturing construction structures, shipbuilding, bridges, line pipes, machine structures, pressure vessels, and plate products with atmospheric-resistance and corrosion- resistance.Due to the excellent process control in the mill,plates have better thickness and flatness tolerances than those specified by most of the international standards.Some of the developed products are as follows: 1.High-strength plates for ultra-heavy constructionstructural use: They are plates with tensile strength of 570Mpa and more, thickness up to 80mm, low yield/tensile ratios, narrow strength ranges, and good weldability.They were used as the steel frames in the skyscraper of the Taipei Financial Center. 2.Extra Low Yield Vibration-resistant Plates.....
