The differences between ordinary iron nails and galvanized iron nails

There are mainly differences between ordinary iron nails and galvanized iron nails in the following aspects:

1. Rust prevention performance: Ordinary iron nails are prone to rusting and corrode quickly in humid environments. The surface of galvanized iron nails is covered with a zinc layer, which can effectively isolate oxygen and moisture, significantly enhance rust prevention ability, and extend service life.

2. Appearance: Ordinary iron nails have a rough surface and a dull color. The surface of galvanized iron nails is usually smooth and presents a bright zinc metallic color.

3. Cost: Due to the increase in galvanizing technology, the production cost of galvanized iron nails is relatively higher than that of ordinary iron nails.

4. Purpose: Ordinary iron nails are commonly used in situations where rust prevention requirements are not high. Galvanized iron nails are more commonly used in environments with certain requirements for rust prevention performance, such as outdoor buildings, outdoor facilities, etc.

5. Mechanical properties: Galvanizing treatment may affect the mechanical properties of iron nails to some extent, such as hardness, toughness, etc., but the impact is usually small.

6. Environmental friendliness: The rust produced by ordinary iron nails after rusting may cause certain pollution to the environment. The rust prevention performance of galvanized iron nails reduces the generation of rust and is relatively more environmentally friendly.

There are various sizes of ordinary nails, with common length specifications typically ranging from 10 millimeters to 100 millimeters. For example, 10mm, 20mm, 30mm, 40mm, 50mm, 60mm, 80mm, and 100mm.

Its diameter varies depending on its purpose. Ordinary nails used for lightweight fixation, with a diameter of approximately 1 to 2 millimeters; For heavier fixed objects, the diameter may be between 3 millimeters to 5 millimeters or even thicker.

In practical applications, the choice of size for ordinary nails mainly depends on factors such as the material, weight, fixing requirements, and usage environment of the object being fixed.
