As a professional fence manufacturer, understanding the various techniques involved in fence processing is critical to ensuring the durability, strength, and aesthetics of the final product. In this blog, we will break down the 15 essential processing techniques used in modern fence production. Each method plays a crucial role in shaping and refining the materials into high-quality fences.
1. Stamping
Stamping is a most fundamental fence technique. It uses tonnage presses and precision dies. The process quickly and accurately shapes or cuts metal sheets. Sheets range from 0.5mm to 5mm thick. Stamping offers significant advantages in mass production. Machines achieve hundreds or thousands of strokes per minute. They maintain dimensional tolerance of ±0.1mm or better. This ensures component size and shape uniformity.
2. Cutting
Cutting divides raw materials like sheets, tubes, or profiles. It precisely cuts them to required sizes and shapes. This follows design specifications. Precision sawing achieves ±0.5mm length tolerance. It works well for tubes and profiles. Shearing quickly cuts sheets in batches. It offers high efficiency. Efficient and precise cutting minimizes material waste. Precision nesting enables material utilization over 95%. Cutting accuracy affects overall fence alignment and fit.
3. Bending
Bending uses bending machines and matching dies. It changes a material’s geometric shape. The process does not cut or weaken material continuity. High-precision equipment enables tight bend radii. The minimum radius is 0.5 times the material thickness. It achieves angle accuracy of ±0.5 degrees or better.
4. Laser Cutting
Laser cutting offers very high precision. It suits complex designs and strict tolerances. This applies to fence manufacturing. A focused high-energy laser beam cuts complex, fine patterns. It works on steel and aluminum sheets. Precision stays within ±0.05mm.
5. Punching
Punching creates standard holes or slots on fence components. It is ideal for high-volume, standardized production. Punch presses and dies form desired hole shapes. They work on metal sheets or profiles. This technique controls hole position accuracy within ±0.2mm. It completes the process at very high speed.
6. Welding
Welding is vital in connecting metal fence components. There are different types of welding methods used in fence manufacturing, including Metal Inert Gas (MIG) welding and Tungsten Inert Gas (TIG) welding. MIG welding is often used for its speed and ease, while TIG welding provides more precision, particularly for intricate joints or thin materials. Welding ensures that fence sections are securely fastened together, enhancing strength and durability.
7. Slag Removal
After welding, slag forms as a byproduct, which must be removed to maintain the fence’s aesthetics and structural integrity. This fence processing techniques cleaning process, known as slag removal, ensures that the welds are smooth, reducing the chances of corrosion and improving the appearance of the fence. Proper slag removal also contributes to the longevity of the fence, as it prevents rust buildup.
8. Pickling
Pickling involves using a chemical solution to clean the metal surface of oxides or impurities that form during processing. This is essential before applying coatings, as it ensures the surface is clean and ready for further treatment. Pickling enhances the metal’s resistance to corrosion and ensures that surface treatments such as galvanizing or painting adhere properly, adding longevity to the fence’s life span.
9. Phosphating
Phosphating is another surface treatment technique. Manufacturers use it in fence production. Its main purpose is improving metal corrosion resistance. It also significantly enhances coating adhesion. This phosphating film significantly improves paint or powder coat bond. It increases adhesion to the metal substrate. And also boosts scratch resistance. Pull-off strength increases by over 30%.
10. Electro-Galvanizing
Electro-galvanizing uses an electrochemical method. It deposits a zinc coating on metal fence surfaces. This process provides basic corrosion protection. This process has relatively low cost. It offers fast processing speed. The resulting zinc layer is typically thin. Thickness ranges usually from 5 to 25 micrometers. This coating delays metal material rusting.
11. Hot-Dip Galvanizing
Hot-dip galvanizing effectively prevents fence corrosion. It immerses components completely. Immersion uses molten zinc. The bath temperature is about 450°C. This process creates a much thicker zinc layer. It exceeds electroplating and other methods. Standard hot-dip coating thickness usually reaches 60 to 100 microns. Hot-dip galvanized fences prevent rust for 20 to 50 years. This is true in typical urban and rural areas.
12. Dacromet Coating
Dacromet coating is innovative thin-layer tech. It prevents corrosion. It is known for excellent high salt spray resistance. This process applies a mix via dipping or spraying. The mix has zinc, aluminum, binders. It covers fence surfaces. Then it low-temp cures around 200-300°C. It has excellent heat and chemical resistance. and also has good adhesion and permeability, suits high corrosion applications especially well.
13. Electrophoresis (E-coating)
E-coating is an advanced method. It ensures uniform, consistent coating. This covers all fence components. This process dips metal parts in paint tanks. It applies an electric charge. This makes paint particles adhere evenly. The particles cover the surface uniformly. After curing, E-coating thickness is generally 15 to 30 microns. It often serves as a primer. This greatly boosts final coating adhesion. It also enhances impact and corrosion resistance. Most of our Farm Accessories adopt this process, so they can be suitable for long-term farm environment erosion and give customers a better user experience.
14. Powder Coating
Powder coating is a dry process. It sprays electrostatic powder onto fence material. We then place fences in an oven. They cure to form a smooth layer. This layer prevents chipping, scratches, UV damage. Powder coating thickness is usually 60 to 120 microns. It is thicker than liquid paint. This provides excellent physical protection. Our Palisade Fencing, Garrison Fencing, and Spear Top Fence all use powder coating technology, so they are highly safe and durable, and there are a variety of specifications to choose from.
15. Dip Coating
Dip coating immerses fence components. They go into a liquid coating solution. This method very effectively adds a thick layer. It provides uniform corrosion protection. Dip coating greatly boosts corrosion resistance. This contrasts with ordinary paint. It can last 10 to 15 years. This occurs in wet or salty soil. Our Star Pickets adopt this process, so they are suitable for various outdoor environments, have excellent performance, and very long service life.
