Shanxi waveform guardrail manufacturer

Description :

The waveform guardrail (waveform beam steel guardrail) in Shanxi follows the national unified specifications and standards, but has certain regional characteristics in terms of anti-corrosion technology and manufacturer distribution. Based on your previous focus on Liaocheng manufacturers, here is a summary of the core situation of the Shanxi market for you.

1、 What does Shanxi waveform guardrail look like?

This is the common "W-shaped" steel strip on the highway, which uses corrugated deformation to absorb impact energy. A complete set of guardrails consists ofGuardrail panels, columns, blocking blocks/brackets, boltsform.

1. Common specifications (mainstream in Shanxi projects)

• Double wave board (most commonly used): length 4320mm x width 310mm x wave height 85mm. 2.5mm thick is commonly used for rural roads, 3.0mm for national and provincial roads, and 4.0mm for highways or high-risk sections.
• Three wave board (reinforced type): length 4320mm x width 506mm x wave height 85mm, thickness usually 4.0mm, used for high-speed or cliff sections.
• Column: Round tube diameter 114mm or 140mm, wall thickness 4.0-4.5mm, length 1.2-2.15m.

2. Shanxi characteristics: higher anti-corrosion requirements

In winter, some areas of Shanxi will sprinkle snow melting agents (containing chloride salts), which are highly corrosive. In addition to basic hot-dip galvanizing, many projects requireHot dip galvanizing+spray coating(Double coating), mostly green or blue in color, with a longer lifespan than single galvanizing.

2、 How to choose the anti-collision level? (Reference for Shanxi Road Conditions)

Shanxi has complex terrain (both mountainous and plain areas), and the selection mainly depends on the risk of road sections:

• Gr-C level (low risk): suitable for rural roads and county roads in Shanxi (slow speed). The configuration is usually a double wave plate with a thickness of 2.5mm and equipped with a Φ 114mm column.
• Gr-B/Class A (standard risk): applicable to provincial roads, second-class highway and urban expressways in Shanxi. The mainstream configuration is a double wave plate with a thickness of 3.0mm and a column diameter of Φ 114/140mm.
• Gr-SB/SA (high risk): applicable to Shanxi expressway, first-class highway and mountain cliff section. Three wave thick plates (4.0mm) or reinforced double waves must be used, with thicker and denser columns.

3、 Local manufacturers and procurement suggestions in Shanxi

If you are in Liaocheng, Shandong and the project is in Shanxi,Freight is the main costThere are many guardrail factories in Shanxi, mainly concentrated inTaiyuan Stainless Steel Industrial Park(Jiancaoping District), as well as Changzhi, Lvliang and other places.

Procurement suggestion:

1. Clear standards: Some non-standard projects in Shanxi may use 2.75mm or 2.85mm boards, and projects with strict acceptance must adhere to the 3.0mm national standard.
2. Check the zinc layer: In winter in Shanxi, there are many snow melting agents, and it is recommended that the zinc plating amount not be less than 600g/㎡ (or zinc layer ≥ 85 μ m), otherwise it is easy to rust.
3. Freight comparison: Sending logistics from Liaocheng to Shanxi (such as Taiyuan and Jinzhong) is much closer than going to Sichuan, but if the quantity is large, it may be more cost-effective to directly find manufacturers in Shanxi (such as Taiyuan Glaris, Nastuo, etc.) to quote the "landed price".

If you have specificLocation of Shanxi project(such as Yuncheng and Changzhi) androad typeI can help you determine more accurate configurations and approximate delivery prices.
