Corrugated nails are specialized fasteners designed for connecting materials such as corrugated cardboard, wooden boxes, and wood-based building materials. Their core features include a wide nail head and a tough nail shank, which can effectively disperse pressure and prevent cracking of the fixed materials. They have strong installation adaptability and can be used with manual hammering or pneumatic tools. Widely applied in packaging, construction, furniture manufacturing, and other scenarios, they are practical nails that balance fixing strength and material protection.

Core Product Features

1. Strong Adaptability in Structural Design

Wide Head for Crack Prevention: The diameter of the nail head is 15%-30% larger than that of ordinary iron nails, providing a larger contact area with the material. This avoids deformation of corrugated cardboard and cracking of wood caused by excessive local pressure during nailing.
Anti-Slip Nail Shank: Most models adopt a ring-shaped or spiral-threaded nail shank design. After being driven in, it engages more tightly with the material, and its pull-out resistance is increased by over 20% compared to smooth-shank nails, ensuring no loosening during long-term use.
Optimized Nail Point: The nail point undergoes special grinding treatment, featuring strong piercing power. It can quickly penetrate corrugated cardboard and multi-layer wood boards, reducing installation resistance and improving work efficiency.

2. Diverse Materials and Surface Treatments

Base Materials: Mainstream options include Q195 low-carbon steel and Q235 carbon steel, which offer good toughness and are not easy to break. For special scenarios, 304 stainless steel can be selected, which has moisture resistance and rust resistance, making it suitable for outdoor or humid environments.
Surface Treatments: Multiple anti-rust solutions are available, including electro-galvanizing (for rust prevention in daily dry environments), hot-dip galvanizing (for moderate rust prevention, suitable for semi-outdoor scenarios), and phosphating treatment (to improve wear resistance, suitable for high-frequency installation), meeting the needs of different usage environments.

3. Complete Specifications for Multi-Scenario Adaptation

Cover a common range of nail lengths, from 16mm (suitable for single-layer corrugated cardboard) to 80mm (suitable for combinations of multi-layer wood boards and corrugated paper), allowing flexible selection based on the thickness of the fixed material.
The wire diameter ranges from 1.8mm to 4.0mm, balancing strength and installation convenience. This avoids material damage caused by excessively thick wire diameters and insufficient fixing due to excessively thin ones.

Application Scenarios

Packaging Industry: Used for sealing corrugated cartons and assembling wooden boxes. Especially suitable for heavy cargo packaging, it can enhance the load-bearing capacity of the box and prevent the box from falling apart during transportation.
Construction and Decoration: Fixes wooden ceiling keels and wall decorative panels. The wide head design prevents cracking of decorative materials and improves the aesthetics of installation.
Furniture Manufacturing: Assembles simple wooden furniture (such as storage cabinets and bookshelves). It is suitable for connecting boards to boards and boards to corrugated paper liners, balancing firmness and light weight.
Outdoor Scenarios: Corrugated nails made of 304 stainless steel with hot-dip galvanizing can be used for fixing outdoor wooden fences and flower racks. They resist rain erosion and extend service life.
