Steel nails are metal products made from carbon steel as the main raw material and processed through a series of processes for fastening and connection. They are widely used in construction, decoration, woodworking and other fields. The following is a detailed introduction for you:
• Structure and materials
Structure: Steel nails are generally slender rod-shaped, with a sharp nail head at one end for easy penetration of objects, and a flat or dome shaped nail cap at the other end for easy tool tapping.
Material: Common materials include medium carbon steel or high carbon steel. Some special purpose steel nails may also add alloying elements to enhance their specific properties, such as adding chromium, nickel, and other elements to rust proof steel nails to improve their corrosion resistance; Adding elements such as manganese and vanadium to high-strength steel nails enhances hardness and toughness.
• Manufacturing process: Usually, steel is cut into billets of appropriate length, and then formed into the basic shape of the nail cap and nail body through cold heading or hot heading processes. Then, the nail head is ground to make it sharp and easy to nail into objects. Some steel nails will also undergo heat treatment to enhance their hardness and strength, meeting the needs of different usage scenarios.
Function: The main function is to fix objects together, drive steel nails into the connected objects through external force, and achieve a firm connection by relying on the friction and biting force between oneself and the object, such as fixing templates during construction, installing skirting boards during decoration, and splicing wood in woodworking.
• Type and application
Round nail: The most common type, widely used in woodworking, construction, and other fields to connect wood and fix objects.
Cement steel nails: With high hardness, they can be nailed into hard materials such as concrete and brick walls, and are used to fix objects in construction and decoration.
Nail shooting: Used in conjunction with a nail gun, it has high construction efficiency and is suitable for fixing doors, windows, keels, etc. on materials such as concrete and steel.
Horse riding nail: shaped like a "U", used to fix metal mesh, wires, etc., commonly seen in fields such as construction and agriculture.
Industry standards: In China, the production of steel nails must comply with relevant standards such as GB/T 349-2018 "General Technical Conditions for Steel Nails", which regulate the size, technical requirements, test methods, inspection rules, and other aspects of steel nails to ensure product quality and safe use.
