In addition to this aluminum spear top fence, we also have other spear top fence products. Our series of commercial spear top fences has significant differences in multiple aspects.
Aluminum spear top fence: The main body of the ordinary mitre aluminum fence is made of regular-thickness aluminum. Only the top part is designed as a mitre to prevent climbing, emphasizing both aesthetics and basic security. The height is moderate, the spacing is uniform, and it facilitates clear line of sight. It is mostly used in ordinary commercial and residential areas.
Garrison fence: Most military perimeter fences are mainly made of thickened high-strength steel. The height is higher than that of ordinary fences, and the spacing is small to prevent climbing over. It can be welded using face welding methods to ensure that all parts of the fence are firmly fixed. It is mostly used in places with high security requirements, such as factories, prisons, and military camps.
Aluminum Spear Top Fence vs. Steel Spear Top Fence
The aluminum spear top fence and the steel spear top fence are both fences with a sharp spear-like top design. They are commonly used for perimeter protection incommercial and industrial sites to enhance deterrence and prevent climbing. The main difference between them lies in:
Aluminum spear top fence: Made of aluminum, it is lightweight and corrosion-resistant, but its impact resistance is not as good as that of steel fences. The surface is usually treated with powder coating or anodizing, which can effectively resist erosion from rain, salt spray, and ultraviolet rays, and has a lifespan of 20-30 years. It is particularly suitable for coastal or humid environments.
Steel spear top fence: Made of steel, it has high strength but is prone to rust. It has strong resistance to bending and impact, and is safer. It is suitable for places with high safety requirements. It needs to be galvanized or coated with an anti-corrosion layer, and the maintenance cost is higher. It performs well in dry environments, but when exposed to damp or acid-rain areas, the corrosion risk is greater, and its lifespan is about 10-20 years.
