Features of threaded rods

Threaded rods are considered an important detail in the assembly process. It is a straight rod whose length ranges from 1-3m. threaded rods are used to connect auxiliary structures (high-rise water systems, fire fighting systems, cable systems, etc.) to the stable structures of the building or to fix the concrete formwork.

The surface of threaded rods is smooth and even spirals called threads, which help it do the fast and easy task of fastening with accessories, creating strong bonds that are difficult to break.

Currently, on the market there are many types of threaded rods that differ in size, shape, material and quality. Depending on your needs, finances and actual construction conditions, you can then choose the appropriate threaded rods products, ensuring the safest construction.

Threaded rods classification

Normally, people will classify threaded rods depending on the characteristics of threaded rods as follows:
Classification based on durability

Since threaded rods are often used mainly for pulling parts, durability is paramount. Users need to calculate how much force and cross-section the threaded rods can withstand. From there, make calculations and choose accordingly.

Common types of durable grade threaded rods:

– threaded rods grade 4.8: are threaded rods of normal strength and have a minimum tensile strength of 4000 g/cm2.
– threaded rods of durability grade 5.6: are threaded rods of medium strength and have a minimum tensile strength of 5000 kg/cm2.
– threaded rods grade 8.8: are threaded rods with high durability and a large bearing capacity of at least 8000 kg/cm2. Classification of threaded rods by coating grade

Threaded rods often have a coating on the outside to ensure aesthetics when assembled with products and enhance resistance to weather conditions. Based on this coating, people can be divided into the following categories

– Electroplated threaded rods: this is the most popular type of threaded rods, because of its high durability in dry environments and its affordable price.
– hot-dip galvanized threaded rods: this type of threaded rods has high carrying capacity in outdoor environmental conditions. With thick plating and large diameter threaded rods.

Sort by size

+ threaded rods M6/d6 (phi 6): use workpieces with diameters from 4.6mm-5mm.
+ threaded rods M8/d8 (phi 8): use workpieces with diameters from 6.8mm – 7mm.
+ threaded rods M10/d10 (phi 10): use workpieces with diameters from 8.6mm-8.8mm.
+ threaded rods M12/d12 (non 12): use workpieces with diameters from 10.5 -10.8mm.

Besides, there are many other diameters such as: M16/M18/M20,…M56.

Threaded rods are a very important accessory in the construction industry, especially in the construction and installation of formwork. A quality threaded rod product that fully meets the standards will help formwork be firm and ensure safety during construction. So what are threaded rods? Many construction workers also have difficulty in defining and selecting quality threaded rods. In this article, Ty Viet will explain what the definition of threaded rods is and fully list the corresponding threaded rods standard specifications.

What are threaded rods?

threaded rods is a straight element with a starting length from 1 meter to 3 meters, which is used to connect the fixed structures of the building with auxiliary structures such as cable tray ladder system, building electricity and water, rescue, etc. fire. Because of their length and rigidity, threaded rods are often used with vertical connections.

Not only that, threaded rods are also one of the most mentioned film-coated formwork accessories in the work of shackles – pillars – walls before pouring concrete.

Standard specification threaded rods of all kinds

1. Standard threaded rods for loads

The load of threaded rods is understood as its “limited endurance” when in use. The exact loading of a mechanical product such as a toothpick is demonstrated by a tensile test.

2. Length

Is the sum of points on the same line – is the longest distance from one end to the other threaded rods
threaded rods range in length from 1 meter – 3 meters. But still can cut according to customer requirements when needed.

3. Diameter

Since threaded rods have a circular cross-section, its diameter will be the maximum distance between any two points on the circle of the threaded rods cross-section.

The diameter parameter helps us to correctly name and distinguish threaded rods from each other. For example, the 12 bar has a diameter of 12 mm, the 16 bar has a diameter of 16 mm and the diameter of 17 will be 17 mm.

4. Lace step

Thread pitch is the distance between two adjacent thread vertices on the same line calculated by the length of the threaded rods axis

Galvanized threaded rods or other names are threaded rods, steel teeth, suspension rods, ceiling mounts, cable trays are extremely important products in construction work, especially in the installation of electricity and water systems. air conditioning, fire protection systems in high-rise buildings and factory systems. Different types of threaded rods have different applications and play an important role in a wide variety of construction, mechanical, mechanical and civil engineering systems.

What are threaded rods? Types of threaded rods are popular on the market today

threaded rods, also known as threaded rods, tie rods, threaded rods are a long straight steel rod that is threaded with the whole body, often used with nuts to connect fixed structures of construction, mechanical work.

Based on the characteristics of size, strength and plating, threaded rods will be classified in the following ways:

1. Classification according to durability

+ threaded rods with durability level 4.6: These are threaded rods with normal durability.
+ threaded rods grade 5.6: These are threaded rods with medium durability.
Threaded rods grade 8.8: These are high-strength threaded rods that can withstand great traction.

2. Sort by size

+ threaded rods M6/d6 (phi 6): use workpieces with diameters from 4.6mm-5mm.
+ threaded rods M8/d8 (phi 8): use workpieces with diameters from 6.8mm – 7mm.
+ threaded rods M10/d10 (phi 10): use workpieces with diameters from 8.6mm-8.8mm.
+ threaded rods M12/d12 (non 12): use workpieces with diameters from 10.5 -10.8mm.

Besides, there are many other diameters such as: M16/M18/M20,…M56.

3. Classification by outer coating

+ hot-dip galvanized threaded rods: This type of threaded rods is made of steel material and then coated with an attached layer on the surface by hot-dip galvanizing. This method is usually applied to threaded rods with diameter D14 and above. This type is able to withstand the impact from the outside environment well.

+ Electroplated threaded rods: Electroplated threaded rods are usually applied to threaded rods of small diameter, when hot dip plating technique can affect the structure of these types due to high temperatures. This is a popular product that is often used because it is quite affordable and has good tolerance in dry environments.
