Brief Introduction
The cap of the corrugated nail is umbrella-shaped. This unique shape enables them to better adapt to the undulating structure of corrugated cardboard and have a larger contact surface with the corrugated cardboard, thus providing a more stable fixing effect. The nail body is generally slender, with a diameter usually between 1.0 and 2.0 mm, and the length varies according to different usage requirements. The common length is about 15-60 mm. Corrugated nails are generally made of high-quality carbon steel, with high strength and toughness. They can smoothly penetrate the corrugated cardboard without bending or breaking easily and provide reliable fixing force. At the same time, in order to prevent rust, the surface is usually galvanized or nickel-plated, which not only increases the corrosion resistance of the nails but also makes their appearance more beautiful.

Advantages and Features
Efficient Fixing
The special shape and size design of corrugated nails enable them to quickly and accurately penetrate the corrugated cardboard, and after penetration, they can be tightly combined with the cardboard, effectively preventing the cardboard from loosening or separating during transportation and storage, greatly improving the stability and reliability of packaging.
Convenient Operation
Whether it is manual operation or using automated equipment, corrugated nails are easy to install. During manual operation, due to the slender body of the nail, it is easy to hold and easy to control the force and direction when knocking; on the automated production line, corrugated nails can be quickly and accurately driven into the corrugated board through special nailing machines and other equipment, improving production efficiency and reducing labor costs.
Low Cost
The manufacturing process of corrugated nails is relatively simple, and the material cost is also low, so the price is relatively affordable. For companies that use a large number of corrugated board packaging, using corrugated nails as fixing materials can effectively reduce packaging costs while ensuring packaging quality.
Strong Applicability
Corrugated nails can be selected according to different corrugated board thickness, hardness, and packaging requirements, and have strong applicability. Whether it is a small carton packaging or a large wooden box packaging, corrugated nails can play its fixing role.
The Process to Make Roofing Nails
Raw Material Preparation
High-quality low-carbon steel wire is usually used as the nail rod material, and low-carbon steel plate is used to make nail caps. The steel wire in the form of a wire rod is passed through a wire drawing machine and drawn into a cold-drawn wire of a specific thickness according to the specifications of the required corrugated nails, in preparation for the subsequent production of nail rods; at the same time, the low-carbon steel plate is punched into the shape of a nail cap through a stamping device.
Nail Rod Forming
The drawn cold-drawn wire enters the nail making machine. The nail making machine cuts the cold-drawn wire into a suitable length through a series of dies and mechanical actions, and shapes one end to make it meet the shape requirements of the corrugated nail rod, such as forming a certain taper to facilitate nailing into objects.
Nail Cap and Nail Rod Combination
After the nail making machine completes the nail rod forming, the nail cap will be fixedly connected to the nail rod. Through specific mechanical structures and processes, ensure that the nail cap is firmly installed at one end of the nail rod to form a complete corrugated nail prototype.
Surface Treatment – Polishing
In order to improve the appearance quality and rust resistance of corrugated nails, surface treatment is required. The first is the polishing stage, where the corrugated nails with nail caps are placed in the polishing machine together with sawdust, wax, etc. Under the rotation or vibration of the polishing machine, the corrugated nails rub against the sawdust, wax, etc. to remove burrs and impurities on the surface, making the surface smoother and improving the appearance.
Surface Treatment – Galvanizing
The polished corrugated nails then enter the galvanizing equipment. Common galvanizing methods include hot-dip galvanizing and electro-galvanizing. Taking hot-dip galvanizing as an example, the corrugated nails are immersed in molten zinc liquid. After a certain period of time, a uniform zinc layer will form on the surface of the corrugated nails. This zinc layer can effectively prevent the corrugated nails from rusting, extend their service life, and make them more suitable for various outdoor or humid environments.
Packaging Stage
After the galvanized corrugated nails are completed, they are packaged according to customer needs and market standards. There are many common packaging methods, such as 25kg/box conventional export packaging, 1kg/box and then box, 1kg/bag and then box, 50kg sack packaging, etc.During the packaging process, workers will count the number of corrugated nails and conduct quality spot checks to ensure that the number of products in each package is accurate and the quality is qualified. After that, the packaged products will be packed and stored for shipment.
Finished Nail Products
Appearance
The finished corrugated nail consists of two parts: the nail rod and the nail cap. The nail rod is usually cylindrical, with one end tapered to facilitate nailing into the object, and the other end is fixedly connected to the nail cap. The nail cap is mostly round or oblate, which can increase the force-bearing area and prevent the surface of the object from being damaged when nailing. Its overall length, diameter and other specifications are determined according to the use requirements. The surface is smooth and flat after polishing, galvanizing and other treatments, with uniform color, generally silver-white (the color of the galvanized layer).
Material Characteristics
It is mainly made of high-quality, low-carbon steel with certain strength and toughness. The low-carbon steel material ensures that it has the characteristics of not being easy to break while ensuring hardness to meet the nailing requirements, and is suitable for use on a variety of materials. The galvanized layer on the surface (hot-dip galvanizing or electro-galvanizing) gives it good rust and corrosion resistance, and can adapt to outdoor, humid and other environments.
Application Fields of Roofing Nails
It is widely used in many fields. In the construction industry, it can be used for connecting wooden structures and fixing corrugated boards on roofs. In the packaging field, it is used for binding wooden boxes, cartons and other packaging materials. In the furniture manufacturing process, it is used for splicing and fixing boards. Due to its good performance and scope of application, it has become an indispensable fastener in many industries.
Construction Operation Skills
Holding and Angle Control
When holding the corrugated nail, hold the middle and upper part of the nail body with your fingers to keep the nail perpendicular to the material surface to avoid tilting the nail into the nail, which may cause loose fixation or bending of the nail. If tilted fixation is required (such as splicing angle), the angle must be marked in advance to ensure that multiple nails are evenly stressed.
Strike Force and Rhythm
First, tap the nail head with a hammer. After the nail is initially fixed (about 1-2mm deep into the material), increase the force and drive it in quickly to avoid multiple taps that may cause the nail to deviate.
When it is almost fully driven in, slow down the force to prevent the nail head from penetrating the material surface or damaging the material (especially thin plates).
Fixed Spacing and Arrangement
The spacing between adjacent corrugated nails should be designed according to the material strength and load-bearing capacity. It is usually recommended to have a spacing of 50-100mm to avoid too dense to cause material cracking and too sparse to affect the fixing effect.
The arrangement can be linear or grid-type: the linear type is suitable for single-direction force (such as wooden board splicing), and the grid type is suitable for uniform load-bearing (such as suspended ceilings and partitions).
