Typically you look for suppliers on the web or at the exhibitions. And when you send them price inquiry they all know that you ask a lot of suppliers at the same time. So, to get your order some of them may set prices lower than they can, and when they got your order they start to cut costs.
What are the main problems with steel wire rope and steel chain quality that you may face with?
- Delivery time
This is a very big problem when dealing with a number of Chinese enterprises. So when you purchase wholesale steel wire rope and chain from China, you can easily add one week to the terms, which informs your supplier.
- You got less than ordered
The first way to cut costs is to give less than client ordered. Usually you buy steel wire rope in reels, and factory may give you 1-2 meters less in every reel.
- Cheap galvanization
If you visit your potential supplier – steel wire rope and steel chain manufacturer for the first time, you can ask them to show you the factory where they do galvanization of their products.
There are huge differences between some factories, some of them using fully automatic galvanizing lines and some of them still use man’s labor. And the quality of the zinc coating may varies dramaticly.
Steel wire rope galvanization quality generally can be diveded into three levels, depending on the thickness of the coating:
- Low protection: 15-135 grams of zinc per 1 square meter of the surface of the wire rope,
- Average protection: 60-200 grams of zinc per 1 square meter of the surface of the wire rope,
- High protection: 75-260 grams of zinc per 1 square meter of the surface of the wire rope.
The thickness of the zinc layer on the surface of the steel cable directly affects the corrosion resistance.
There are two main ways of galvanizing of steel wire rope and steel chain: hot-dip galvanizing and cold galvanizing. These two methods differ fundamentally, you can read more about it in the internet.
Cost of cold galvanizing higher than hot-dip, while the zinc layer thickness is easier to control. Therefore, manufacturers of high-quality cable and chains in China choose a method of cold galvanizing for their products.
- Low quality of wire rod (raw material for steel wire rope)
When we talk about the quality of steel wire rope and steel chain, the first thing we must pay attention to is what kind of wire rod is made of. Steel grade directly affects the lifetime of a cable or chain and hardness characteristics.
Below is a table of basic grades of steel are used for the production of steel wire rope and steel chain DIN3055 DIN763 and DIN766 in China:
