Types and design features
Nowadays there is a huge selection of different screeds on the building materials market. They differ in size, material, countries of origin, shapes and colors.
The peculiarity of the ties is that they can be connected to each other, thereby creating one large and strong link.
According to the manufacturers, their clamps can withstand a load of over 100 kilograms, but in reality this is not quite the case.
Advantages and disadvantages
Cable ties or PVC clamps are very popular. They are considered high-strength, flexible models that facilitate cable fastening. They have a wide range of uses, from wiring into bundles to assembling computer equipment.
They are also distinguished by quick installation, a wide range of operating temperatures, and the material’s immunity to chemicals. reactions, quick fastening replacement.
Convenient marking methods
The disadvantages of cable clamps are related to their breaking capacity. They are deformed under the influence of high temperatures and do not have a very aesthetic appearance.
External and internal cable ties
Depending on the purpose of the cables, they are classified:
- To the outside.
- Internal.
External clamps are the most popular among buyers. They are made of very durable material that can withstand more than 100 kilograms of live weight. The clamps also withstand the harshest weather.
Stores specializing in building materials sell frost-resistant nylon ties. They are able to withstand temperatures of -30 degrees.
But there is one “but”: with strong and prolonged UV radiation, such ties begin to weaken and tear.
During repair work, builders often add coal powder to nylon ties, this is necessary in order to significantly increase the strength of the material. Photos of nylon ties can be found in the public domain on any thematic website.
Internal ties are intended for use in apartments as an auxiliary part.

Internal ties cannot particularly boast of their strength, but they can be purchased in a wide variety of color palettes. All this helps to create additional aesthetic sophistication in the room.
Clamp parameters
The sizes of plastic clamps are different, the length ranges from 6 cm to 1.5 meters. The choice of length depends on the number of elements to be connected or fastened.
The width range is limited. But when determining the “power” of fasteners, they are guided by the width. Narrow clamps connect elements weighing over 9 kg, wide (large) - up to 75 kg.
Disposable or reusable?
There are situations when it is not necessary to buy an expensive cable. To avoid unnecessary financial expenses, manufacturers offer their customers to purchase disposable zip ties.
- Acceptable price.
- Wide selection of goods in stores.
- Good strength.
Due to the low cost of ties, you can buy a large number of them and make one very strong link of great length from them. Based on this, we can conclude that disposable zip ties are an economically beneficial solution for any owner.
Reusable cables have a significant difference in price, but they are of better quality, which will allow them to last much longer.

From this we can conclude: The price-quality ratio of the reusable cable is absolutely justified.
As previously mentioned, such screeds withstand the vagaries of the weather and can withstand temperatures below -25 degrees.
Clamp colors
The clamps have different colors. When choosing colors, they focus not only on the aesthetic factor, but also on the characteristics of products, depending on the color scheme.
In outdoor conditions, it is recommended to use black clamps due to their resistance to ultraviolet rays. Carbon powder added to the composition increases the service life of the clamp.
With a range of colors, it is convenient to mark fasteners, highlighting them in different directions and purposes.
Tie sizes
If we rely on the standard sizes of screeds in European countries, then the average length of any tie is 500 millimeters.
Our country has its own standards by which manufacturers work. The size of the ties in the Russian Federation is 250 millimeters and the width is 24 millimeters.
Types of fastenings
Plastic clamps can be disposable or reusable. A disposable clamp is cut with some kind of device (knife, saw, etc.) and its further use is stopped.
The reusable plastic clamp is suitable for long-term use thanks to a special clamp (lock). If necessary, the fastening can be released or removed without damaging the clamp.
There are clamps with anchor fastening and with holes for screws.
Factors that reduce the quality and service life of screeds
Various chemicals. If they get on the screed, it will have a negative impact on it and can lead to its complete rupture and impossibility of operation.

Temperature. Screeds can withstand cold temperatures, but not hot ones. Temperatures above 80 degrees will also most likely lead to rupture.
Vibration. If the slightest vibration occurs near the cable, this also has a negative effect on it.
Where are clamps used?
Plastic clamps are most actively used in collecting and fastening wires, cables, hoses, pipes, electrical networks, etc. Various connections are created (rigid and movable), which are characterized by reliability and safety.
Considering the resistance to mechanical, chemical, and temperature influences, the use of clamps is unlimited; they are used both indoors and outdoors. For example, fastenings “work” at temperatures above 120 degrees Celsius.

What are nylon zip ties used for?
Initially, clamps were intended for electrical installation work, but over time their scope of application has increased significantly.
Clamps are mainly used to perform the following tasks:
- fixation of the cable system and its components;
- preventing tangling of the wire network;
- rigid or flexible fastening of pipelines;
- sealing connections.
Using such convenient mounts will allow you to perform many tasks, while minimizing the time spent.
Criteria for correct selection
How to choose nylon ties? Before making a purchase, it is recommended that you familiarize yourself with the following criteria:
High-quality nylon ties consist of fire-resistant polyamide. This material gives the product strength. There are several types of items on sale. They can contain up to 50% polyethylene. Such models are easily flammable and burn quickly.
Cross-sectional area of a plastic strip. As noted above, wide products are particularly durable. They are suitable for strengthening plastic pipes or heavy street wires.
Additional options. There are many product models with additional components on sale. One of these is the dowel element. It is located at the top of the tie under the lock. This part is designed for tightly fixing metal products in the plane of the wall.
Screeds with a mounting hole are used during finishing work. There is a small plastic hole at the end that acts as a guide during the process of attaching parts. This option is used for fixing sewer pipes and connecting high-voltage lines;
When choosing suitable materials, it is recommended to test their flexibility. To do this, form a loop of small diameter. If the surface of the strip is severely deformed and microcracks appear, then the purchase must be abandoned.
During the process of connecting the cable system, such nylon ties may burst. This is due to the incorrect composition of the product.
As a rule, there is a low level of polyamide here, which significantly affects the technical parameters of this part. The photo of a nylon tie shows popular product models.
