Highway guardrail net is the most common type of guardrail net product. It is braided and welded with domestic high-quality low-carbon steel wire and aluminum-magnesium alloy wire. It has the characteristics of flexible assembly, strong and durable. It can be made into a permanent guardrail network wall and used as a temporary isolation network. It can be realized by using different column fixing methods during use. In recent years, highway guardrails have been widely used on many domestic highways and have achieved good results.
There are two most common types of highway guardrail nets: one is the bilateral guardrail net, and the other is the frame guardrail net.
1. Common specifications for bilateral highway guardrail nets (bilateral guardrail nets):

Features of highway guardrail nets: Highway guardrail nets are brightly colored, anti-aging, corrosion-resistant, flat, strongly tensioned, and not susceptible to impact and deformation by external forces. They have strong flexibility in on-site construction and installation, and the structural shape can be adjusted at any time according to on-site requirements. and sizes, and can also be used with corresponding columns. Because it adopts the installation mode of mesh and column combination, it can be easily transported and is not restricted by terrain fluctuations during installation.
Highway guardrail network has the characteristics of simple grid structure, beautiful and practical, easy to transport, and its installation is not restricted by terrain fluctuations. It has strong adaptability to mountains, slopes, and multi-bend areas. Mainly used for protective belts on both sides of highways, railways, and bridges; security protection at airports, ports, and docks; isolation and protection of parks, lawns, zoos, pools, lakes, roads, and residential areas in municipal construction; guesthouses and hotels , protection and decoration in supermarkets and entertainment venues.
