Through different surface treatment processes on the expanded steel mesh, it not only has a more beautiful finish, but also has excellent corrosion resistance and anti-aging properties, thereby extending the service life of the expanded steel mesh.
We can provide you with hot-dip galvanizing, powder coating, anodizing, PVDF and other expanded steel mesh surface treatment processes:
--Hot-dip galvanizing is an effective and widely used surface treatment process to delay corrosion of carbon steel materials.
In order to remove iron oxide on the surface of carbon steel, we will pickle the expanded steel mesh made of carbon steel, and then put it into ammonium chloride, zinc chloride or their mixed solution for cleaning again.
Then put the cleaned expanded steel mesh into a hot-dip galvanizing tank to allow the iron and zinc to fully react and form a zinc alloy coating on the surface of the expanded steel mesh.
The coating has the characteristics of uniform coating, strong adhesion and good density. The advantages of the hot-dip galvanizing process are that it is economical and effectively prevents the rust problem of steel materials.
The hot-dip galvanizing process is mostly used in applications such as walkways, stair treads, and safety fences.
--Powder spraying is to use an electrostatic spraying machine to spray powder onto the surface of the steel mesh.
Under the action of static electricity, the powder will evenly adhere to the surface of the steel mesh to form a powdery coating, which is then baked at high temperature to form coating.
Powder coating is often used in conjunction with hot dip galvanizing of steel mesh products to provide superior service life and a smooth colored surface. The powder coating surface treatment process is widely used, such as road fences, mechanical protection, stair railings, etc.
--Anodizing is an electrolytic process, which is a process in which aluminum and its alloys form an oxide film on aluminum products (anode) under the action of external current under the corresponding electrolyte and specific process conditions.
Usually used in aluminum and its alloy products, it can not only effectively overcome the defects of low surface hardness and poor wear resistance of aluminum, but also the metallic luster oxide film formed on the surface has a very good decorative effect and is an ideal building decoration aluminum steel mesh. Better choice.
--PVDF fluorocarbon spraying is a liquid spraying using polyvinylidene fluoride (PVDF) as the spraying material.
PVDF fluorocarbon coating has excellent weather resistance, acid and alkali resistance, heat resistance, cold resistance, self-extinguishing, self-lubricating, radiation resistance and other properties. It especially shows long-term fading resistance and ultraviolet resistance in harsh climates and environments. performance. Therefore, the service life is 3-5 times that of ordinary paint.
In addition, our fluorocarbon spraying process uses multi-layer spraying, including primer, color topcoat and varnish, which meets the strict requirements of fluorocarbon spraying in the American Building Manufacturing Association AAMA-605.02.90 standard, providing better quality for expanded steel mesh. The surface that combines practicality and aesthetics is an ideal choice for high-end architectural decoration.
