The stone pendant is a stainless steel connecting material that fixes the stone on the wall, that is, an accessory that connects the stone with the metal keel.
Although it is an accessory that is not exposed between the wall and the slate, it is a link that cannot be ignored in the material of the curtain wall accessories and plays a very important role in beautifying the architectural decoration.
Analysis of the importance of the quality of stone pendants:
The general stone pendant fixing forms are:
Short groove anchoring method; back hook anchoring method; through-groove block anchoring method; steel pin anchoring method;
In the past, the traditional fixing methods of stone pendants were dry-hanging structures such as pin type and slot type. The disadvantage of these two methods is that the pendant has to bear a relatively large force, and under normal circumstances, it is easier to break where the plate is slotted, so the operation process The thickness of the medium should not be less than 25mm, and the range of the force should not be greater than 1.5㎡, otherwise it will be damaged due to the excessive pressure.
Under normal circumstances, this kind of stone dry pendant is also made of stainless steel materials, but when it is made, different manufacturers have no longer production standards, and some small manufacturers naturally have no quality. Many problems are prone to occur, and it may reduce a certain cost when purchasing a pendant, but in the end, because of its improper quality, the accident will not be worth the loss, so when buying this kind of pendant, you can’t just look at it. price, but should put its quality first.
How to judge the quality of a stone pendant?
The types of stainless steel pendants are:
Corner code, single hook code (single swallow code), double hook code (double swallow code, butterfly code, swallowtail code), support code (support hook, pick code, warped code, pick piece), flat plate (flat code), T type welding code.
The price of 200 series stainless steel with very low nickel content is only about half of that of 300 series stainless steel, and it is far inferior to 300 series stainless steel in terms of corrosion resistance and toughness. It is only suitable for kitchen utensils, food processing, and other fields. In equipment and other fields, there will be great hidden dangers.
The 200 series products with a nickel content of about 1% cannot withstand general atmospheric corrosion. Commonly used in construction, the installation is more advanced than the first two. The force transmission is simple and the stone damage is reduced, but the phenomenon of “annealing” will occur due to high-temperature heating during welding.
The back of the stone is drilled with bolts and connected to the keel, and the curtain wall dry-hanging system composed of back-cut anchor bolts and rear support system cannot solve the thermal expansion and cold shrinkage deformation caused by temperature difference due to the mechanical anchoring structure without flexible combination. question.
So how to judge the quality of a stone pendant?
1. Look at the material.
Stainless steel products are often compact in structure, and when measured by hand, in addition to being heavier than similar products, they also feel solid and durable;
2. Look at the coating.
The standard plating layer not only makes the surface of the product fine and uniform, but also avoids oxidation and rusting in a humid environment. Look at the surface of the pendant with your eyes, if there is no blister on the surface and the coating is uniform, you can choose.
3. Look at the craftsmanship.
Products processed through strict process standards often go through complex machining, polishing, welding, inspection and other processes. The products not only have beautiful appearance, good performance, but also feel good, uniform, smooth and flawless.
