Lei Ding Iron Art Fence: Dual Anti-corrosion Technology Sets 20-Year Durability Standard

In the field of metal protective facilities, corrosion resistance is the core indicator of product quality. Anping Leiding Metal Wire Mesh Products Co., Ltd. has achieved an industry breakthrough in corrosion resistance with its wrought iron fences, which utilize a dual protective process of "hot-dip galvanizing + electrostatic spraying." The base material is selected as high-quality carbon steel Q235, which is first treated with hot-dip galvanizing to reach a zinc layer thickness of over 85μm, forming a dense zinc-iron alloy barrier that blocks the contact between oxygen and the steel from the source. On this basis, AkzoNobel powder is used for electrostatic spraying, maintaining a coating thickness of 60-80μm. After being cured at a high temperature of 220°C, a hard and smooth protective film is formed.

This dual-protection system has undergone professional salt spray testing and can withstand over 500 hours without rust, far exceeding industry standards. Compared to traditional single-spray techniques, Leiding's ironwork fence has a 3-fold increase in weather resistance, making it particularly suitable for outdoor environments in humid southern regions or coastal cities. In practical use, even after long-term exposure to sunlight, rain, and acidic or alkaline erosion, the fence surface maintains its luster, avoiding issues like paint chipping or rust. China平安 Insurance Company's quality assurance further validates the product's durable promise of "no rust for 20 years," providing long-term and reliable protection solutions for clients in municipal engineering and community property management.
