Since humans discovered metal, metal has been closely related to our lives. How humans discovered it by accident and how to use it, this is indeed a mystery. In short, thousands of years ago, our ancestors' casting and smelting techniques for bronzes reached a very superb level. In the beginning, in order to meet the material needs of survival, people made large quantities of bronzes into production and war products, such as knives, utensils, and plows. Then came the currency and various jewellery, daily necessities, ornaments and architectural decorations.

In the era of manual operation, metal processing mainly relied on smelting, forging, riveting and other technological means. It was considered that the characteristics of metal were more difficult in processing. Products manufactured in this way were impossible to mass-produce, and the craftsmanship was also difficult. It is relatively rough. Until the industrialization era, machine production replaces manual operations, and metal products can enter society and our families in large quantities.

From a historical point of view, although our ancestors used metal earlier, there has not been a great development in metal decoration art. In the West, due to the development of smelting technology and the advent of industrialization, iron art was widely used, and a large amount of it flowed into China at the beginning of the 20th century. Therefore, the various iron arts we see today bear the imprint of Western plastic art style in artistic modeling and pattern texture.

According to the different uses of iron art, it can be classified into six categories, namely:
Building decoration, home furnishing, lamps, brackets, daily necessities, furnishings, etc...
Architectural decoration: including doors, door flowers, handles, windows, window grilles, window rails, fences, base fences, column flowers, beam flowers, wall flowers, screen flowers, handrails, eaves, fireplaces, etc... .
Furniture category: including boarding, chairs, tables, beds, coffee tables, etc...
Lamps and lanterns: including street lamps, floor lamps, table lamps, wall lamps, chandeliers, etc... o Brackets: including bookshelves, benches, flower stands, card stands, etc...
Daily necessities: including tableware, flower baskets, etc...
Furnishings: including desk furnishings, artworks, etc....

As can be seen from the above categories, iron art products almost include most of the items that are exposed to daily life. Moreover, with the improvement of technology, their production is more exquisite and more diverse. Iron art is loved by people because of its distinctive characteristics. In terms of texture, they have a metallic feel, thick and heavy, with exquisite patterns but tough lines. Depending on the processing technology, it will have a different look and feel. The iron art formed by casting has the feeling of being hard, rough, calm and atmospheric; the iron art formed by pressing is flat, smooth, and fine; the iron art formed by mechanical car milling and engraving is small, exquisite, bright and clean; the iron art formed by twisting and bending welding, Strong line shape, elegant feeling, bright graphics; forged iron art, rich in shape and changeable patterns.
