In the global highway construction field, high-quality traffic safety facilities are the core cornerstone of ensuring road traffic safety. As a leading professional manufacturer of highway guardrails in China, Shandong Northern Group has adhered to the business philosophy of "Technological Innovation, Win-Win Cooperation, Integrity and Efficiency, and First-Class Service" since its establishment in 2009. With strong production capacity, strict quality control and extensive market layout, it provides reliable traffic safety product solutions for global transportation infrastructure projects and has won high recognition from customers at home and abroad.

In the roar of global construction tower cranes, the flow of automotive production lines, and even on the casings of household appliances in every home, hides an unassuming yet crucial material—galvanized steel coils. With its excellent corrosion resistance, flexible processing characteristics, and affordable cost, it firmly occupies the core position in the supply chains of many industries. Especially hot-dip galvanized steel coils, through a set of precise coating processes, enable steel that is originally prone to rust to "serve" for many years in harsh environments such as rainy seasons, coastal salt spray, and acid-base factories, laying a solid quality foundation for numerous engineering projects and industrial production. Wondering how many advantages it actually has and which scenarios it can adapt to? Let's take it step by step.

Galvanized steel pipes are increasingly widely used in water supply and drainage, fire protection, heating, ventilation, and industrial transportation fields due to their excellent corrosion resistance, long service life, and cost-effective advantages. However, the welding process of galvanized steel pipes is special. The galvanized layer on the surface is prone to melting, evaporation and other reactions under the high-temperature welding environment. If the operation is not standardized, it is likely to cause defects such as porosity, cracks, and slag inclusion in the weld. This will not only reduce the joint strength and tightness, but also may shorten the overall service life of the pipe and even cause potential safety hazards. To help relevant practitioners master scientific welding technology, avoid construction risks, and ensure project quality, this article will systematically sort out the core points and precautions of galvanized steel pipe welding from key links such as pre-welding preparation, characteristics of galvanized steel pipes, process control, and operating techniques.

In June 2025, the inspection report of a fishery-photovoltaic complementary power station in Binzhou, Shandong Province, shocked the industry - the photovoltaic brackets built at the same time showed a polarization: the hot-dip galvanized steel brackets had obvious rust, the aluminum alloy brackets had slight deformation due to insufficient load-bearing capacity, while the brackets made of zinc-aluminum-magnesium materials were as clean and shiny as new! This case has exposed the "hidden pain point" in the photovoltaic industry: material selection is becoming a key variable in the revenue of power stations.

In road traffic safety facilities, the anti-corrosion performance of wave-beam guardrails directly determines their service life and protective effect. Spray coating and dip coating are the two most commonly used anti-corrosion processes for wave-beam guardrails. Although both use "plastic" as the anti-corrosion medium, they differ significantly in process principles, coating characteristics, applicable scenarios and other aspects. This article will deeply analyze the differences between the two from multiple dimensions to provide reference for relevant practitioners and purchasers.

Amid the global wave of carbon neutrality and infrastructure development, hot-dip galvanized steel continues to dominate in 2025 thanks to its long lifespan, 100% recyclability, and unmatched cost-performance ratio. Choosing the right zinc coating thickness means choosing peace of mind for the next 20-50 years.

In steel trading and industrial manufacturing, choosing the right raw material is crucial for the quality of the final product. Our Hot-Dip Galvanized Steel Coils (HDG) are designed for clients seeking high strength and longevity. By using premium cold-rolled steel as the substrate, we ensure that every coil possesses not only superior corrosion resistance but also perfect surface flatness.

In the world of modern highway infrastructure, road safety is non-negotiable. When we talk about passive safety systems, the W-Beam Steel Guardrail remains the most widely used and trusted solution globally.
