As a basic hardware product, iron nails are widely used in fields such as construction, furniture manufacturing, packaging, and industrial equipment. The following provides a comprehensive analysis from the aspects of raw materials, production processes, specification classification, application fields, and market trends.
1、 Raw materials
1. Steel type
-Low carbon steel (Q195/Q235): the most common raw material, with moderate strength, easy processing, and low cost.
-Medium high carbon steel (45 #, 60 #): used for high-strength nails (such as cement nails), requiring quenching treatment to increase hardness.
-Stainless steel (304/316): Strong corrosion resistance, suitable for humid or outdoor environments.
2. Surface treatment materials
-Galvanization: divided into electroplated zinc (bright silver) and hot-dip zinc (dark gray), with excellent rust prevention performance.
-Coating/painting: increases color diversity and weather resistance, commonly used for decorative nails.
-Phosphating/Blackening: Improve surface wear resistance, suitable for industrial fastening scenarios.
2、 Production process
1. Wire processing
-Steel is drawn into wire of the required diameter through cold drawing process.
2. Forming
-Cold heading forming: Cutting and forging nail heads and tips from wire using a mold.
-Thread machining (such as threading nails): Rolling or cutting to form the threads of the shaft.
3. Heat treatment
-Medium to high carbon steel nails require quenching (to increase hardness) and tempering (to reduce brittleness).
4. Surface treatment
-Electroplating, hot-dip or coating processes enhance anti-corrosion performance.
5. Package
-According to specifications, it is commonly packaged in boxes or rolls (such as staples).
 3、 Specifications and Classification
1. Classified by purpose
-Ordinary round nail: universal type, used for fixing wood and lightweight building materials.
-Cement nail: high hardness, can be nailed into concrete or brick walls.
-Decorative nails: copper head, nickel plating, etc., used for furniture and leather decoration.
-Special nails: such as U-shaped nails (code nails), corrugated nails (wave resistant rod body).
2. Classify by size
-Length: commonly ranging from 10mm to 200mm (e.g. 1 inch ≈ 25mm, 4 inches ≈ 100mm).
-Diameter: 0.8mm to 6mm, matching the length determines the load-bearing capacity.
3. Special structure
-Ring nail: a circular groove on the shaft to enhance friction;
-Threaded nail: Similar to a screw, used in high pull-out scenarios.
4、 Application Fields
1. Construction engineering
-Wooden structure fixation (such as keel, formwork), gypsum board installation.
2. Furniture manufacturing
-Panel splicing, soft packaging furniture fixation, and decorative nails enhance aesthetics.
3. Packaging industry
-Wooden boxes and pallets are nailed together, and U-shaped nails are used for sealing cardboard boxes.
4. Industrial equipment
-Mechanical components are temporarily fixed, and stainless steel nails are used in corrosion-resistant environments.
5. Agriculture and Horticulture
-Greenhouse construction, fence fixation, galvanized nails for rust prevention and durability.
5、 Market Trends and Innovation
1. Environmental requirements
-Promote cyanide free galvanizing and water-based coating processes to reduce pollution.
2. High performance requirements
-Composite coatings (such as zinc nickel alloys) enhance the anti-corrosion level;
-Titanium alloy nails are used in extreme environments such as ships and chemicals.
3. Intelligent production
-Automated cold heading equipment improves efficiency and reduces labor costs.
4. Emerging applications
-Integrated design of metal nails and structures in 3D printed architecture.
6、 Selection and usage suggestions
1. Matching scenarios
-Choose galvanized/stainless steel nails for humid environments; Quenched cement nails are used for concrete.
2. Quality identification
-Check whether the connection between the nail head and the shaft is firm, and whether the surface coating is uniform without peeling off.
3. Storage precautions
-Moisture resistant packaging to prevent oxidation or rusting of the coating.
Summarize
Although small, iron nails are indispensable fastening components in modern industry and life. Its performance continues to improve with the optimization of materials, processes, and designs, and in the future, more emphasis will be placed on environmental friendliness, durability, and multifunctionality. From traditional architecture to emerging technological fields, iron nails continue to play a key role in “strengthening the big with the small”.
