We recently went to a new building materials store that opened to look at the chain- link mesh .
We decided to check the quality characteristics of the mesh Rabitsa 50x1.8 (cell 50 mm, wire 1.8 mm).
The main characteristic of a grid the Chain-link - its durability. The less metal in the chain-link mesh, the less its strength and the less its price should be. Accordingly, the strength decreases with an increase in the cell and a decrease in the diameter of the wire from which the mesh is made.
We measure.
Cell 50 mm . turned out to be 58 mm (with a maximum tolerance according to GOST 5336-80, it can be no more than 55 mm .)
The wire diameter of 1.8 mm during measurements turned out to be 1.6 (at the maximum tolerance according to GOST 3282-74, it cannot be less than 1.75 mm)
Compare prices:
The chain-link mesh with a 60 mm cell is cheaper than the chain-link mesh with a 50 mm cell by about 11% .
Chain-link mesh with 1.6 mm wire is cheaper than Chain-link mesh with 1.8 mm wire by about 14%
Summary: the mesh manufacturer Rabitsa decided to deceive customers by 25% of the cost of the mesh. What else affects the price of the chain-link mesh .
What to do so that you are not deceived when selling the mesh Rabitsa?
If we talk about the strength of the chain-link mesh, then it is easy to control it by weighing.
Go to the page with the weight of the grid Rabitsa . Find the theoretical weight of the grid you need.
The mesh you order may differ from this weight by no more than 5%.
This means that when buying a chain-link mesh 50x1.8, you need to require that the supplier directly indicate the weight of the chain-link mesh on the invoice: 840 g / m2 (5% tolerance).
Let it be entered manually.
This is necessary so that the manufacturers of the mesh Rabitsa take on quality obligations, and you do not buy a pig in a poke.
If the weight is less, then they tried to deceive you, either by reducing the diameter of the wire, or by increasing the size of the cell, or by selling a shorter or lower roll. You can refuse to buy a mesh already made or demand an adequate price reduction .
Weighing of a grid the Chain-link does not give the chance to deceive you.
If you are comparing prices from different suppliers, then ask for the roll weight and price.
It is clear that manufacturers who intend to deceive the buyer will not tell you its weight.
A negative answer is also an answer and it will tell you a lot.
If one seller tells you that his mesh Netting 50x2 weighs 15 kg per roll and costs 150 UAH, and another supplier says that the same roll weighs 13.8 kg and costs 127 UAH, then you must understand that you are offered different meshes for different price. The fairness of these prices is about the same and it is up to you to decide whether you want to buy a less durable chain-link at a cheaper price or not.
If you are offered the same price for the 50x2 chain-link mesh, but the weight of these rolls will be different for different suppliers, then you can make an unambiguous conclusion.
We deliberately do not convince you of where it is better for you to buy the chain-link mesh, alluding to ourselves. The purpose of this article is to teach a person who does not face the purchase of a Rabitsa mesh every day: how to get the quality of the Rabitsa mesh that you expected for your money and how to correctly compare mesh offers from different sellers.
