We currently offer two types of wavy tail anchors: short and long. The difference between them is the distance from the extrusion point to the wavy tail.

Wavy Tail Anchor Details

We will explain everything about it here. So you can know why our prices are much higher than some of our competitors. But they are much cheaper for the same quality products.

What is Wavy Tail Anchor

Wavy tail anchor is an accessory designed to be placed in precast concrete elements to provide a lifting point or anchor point, also known as wavy tail lifting insert (socket). It plays an important role in the lifting, transportation and installation of precast concrete elements.

What is Its Structure

It has two parts in terms of material: one is the rebar that is bent into a wavy shape, and the other is the socket (insert) with internal threads. The two are connected after being extruded by an extruder. The extruded part can be used as the third part, the neck or shank.

Socket(insert):

The threads of the sockets are tapped and surface treated before assembly, and then assembled with the rebar in the extruder. The openings need to be blocked during pouring to prevent concrete from pouring back into them. Lifting hoist rings or lifting loops are required for hoisting. There are three types of materials: stainless steel, carbon steel and alloy steel.

Neck or Shank:

The structure that connects the socket and rebar is made by using a special extruder. It transfers the load on the socket to the rebar and then to the entire system.

Wavy Tail Rebar:

It is a rebar that is pre-bent into a wavy shape, and the part that connects to the socket is straight. The material is generally HRD 400. It will be deeply embedded in the precast concrete elements to evenly transfer the stress to the entire element and achieve better mechanical interlocking to enhance the pull-out resistance. The wavy structure increases the stress transfer and resistance area with the element. It can better ensure the stability of the element.

What is The Types of Wavy Tail Anchor

It can be divided into long one and short one according to the length of Wavy Tail Rebar. The difference between the two is that one is long and the other is short to connect to the socket, and the application scenarios are also slightly different.

Long Wavy Tail Anchor

Its rebar is longer and can be buried deeper. You can click to enter the details to learn more.

Short Wavy Tail Anchor

Its rebar is shorter. The title is a link to its details page, you can click to enter and learn more.

Note:

Some manufacturers use scrap materials to produce Wavy Tail Anchor, and the cost of scrap materials is only half of the batch raw materials.

The advantage of raw materials is that the material composition is certain and the performance is stable. The quality of the whole batch of goods will be consistent.

The disadvantage of scrap materials is that the material type is uncertain and the quality of the whole batch of goods is uneven.

The price has been reduced, but do you dare to use this batch of orders?

We will strictly check the load performance.

Many merchants may only check one in a batch of orders, or even falsify the data. Do you dare to use it?

We dare to disclose the quality inspection details.

How it work：

The work of wavy tail anchor is mainly divided into three parts: pre-setting, hoisting and anchoring.

Pre-placement:

Each precast concrete element requires several wavy tail anchors, and where to place them needs to be strictly calculated. This process needs to be handled by a professional company, such as HALFEN, LEVIAT, etc., which have such capabilities. Use plastic plugs or magnets for sockets to fix the wavy tail anchors in a specific position and then pour concrete. After the concrete solidifies, remove the plugs and use it.

Lifting：

Use lifting loops or hoist rings screwed into sockets to connect lifting equipment to complete the lifting and transportation of precast concrete elements. The lifting stress will be transferred along the rebar to the deep of the element, preventing breakage and damage.

Anchorage:

It can provide thread points for connecting other parts.

Production of Wavy Tail Anchor:

Its production is mainly divided into three parts: bending, extrusion and tapping.

1. Cutting, cutting the steel pipe and rebar into specific lengths;

2. Bend the tail of the rebar into a wavy shape in a bending machine, and tap the steel pipe;

3. Surface treatment of sockets;

4. Put the steel pipe on the rebar and put it in a special extruder, and complete the connection between the two after extrusion;

Quality inspection of Wavy Tail Anchor:

We mainly inspect the load performance, overall length and thread of wavy tail anchor raw materials and finished products. If you want to see other test data, you can make a request. Our quality control center is equipped with advanced instruments. If it is not possible, we will ask SGS, TUV and other third-party companies to assist in the inspection.

Raw Material Test:

Raw materials will be strictly inspected before they are put into production, and they will only be officially used in production after they are confirmed to meet production requirements. We will provide a detailed material list.

Tension test:

We will strictly sample to ensure that the sample can represent the entire batch of goods, and use a tensile force of 3 times the safety factor for destructive testing. The quality of the goods can be guaranteed to the greatest extent.

Thread inspection:

We have a complete set of go and no-go gauges that can complete the inspection of various threads, and we will also use a more rigorous method to inspect the threads.

Length inspection

We will strictly measure the total length of the wavy tail anchor. Other dimensional measurements will also be strictly carried out.
