Galvanized Flat Bar

Our Shunchen Galvanized Flat Bar is a long strip metal profile with a rectangular cross-section and right-angle (or rounded) edges. It is made of high-quality carbon steel such as Q235A/B and Q355A/B as the base material, and is processed with anti-corrosion treatment through fully automatic hot-dip galvanizing (mainstream) or electro-galvanizing (cold galvanizing) process.

As a professional manufacturer, we strictly control the quality from base material selection to galvanizing processing. This enables Shunchen Galvanized Flat Bar to not only have the high strength and high toughness of the steel itself, but also effectively resist the erosion of air, moisture, acid and alkali media relying on the physical isolation and electrochemical protection of the zinc coating. It can be widely used as structural support, conductive conductor and anti-corrosion connector, adapting to various indoor and outdoor, humid and corrosive scenarios, and greatly extending the service life of the project.

Core Advantages & Selling Points

Superior Corrosion Resistance & Extended Service LifeShunchen Galvanized Flat Bar adopts mature hot-dip galvanizing process, with uniform coating thickness ≥85μm, tight bonding and no missing plating. It can withstand ≥500 hours of Neutral Salt Spray (NSS) Test. Compared with ordinary bare steel, its service life is increased by 3-5 times. It performs excellently in corrosive environments such as coastal areas and chemical industries, greatly reducing the later maintenance costs for customers.

High Strength & Toughness, Flexible ProcessingThe base material is made of standard-compliant high-quality carbon steel, with tensile and bending strength fully meeting the requirements of national standards, and strong plasticity. We can carry out secondary processing such as precision cutting, welding, bending and punching on Shunchen Galvanized Flat Bar according to customer needs, perfectly adapting to the mechanical and dimensional requirements of complex installation scenarios.

High Cost-Effectiveness & Stable SupplyCompared with stainless steel flat steel, Shunchen Galvanized Flat Bar has significant cost advantages. It does not require additional anti-corrosion treatment by customers, and is ready-to-use out of the box, shortening the construction cycle. We have our own production lines and warehouses, with regular stock of conventional specifications. Both bulk procurement and small-batch customization can guarantee timely delivery.

Eco-Friendly Compliance & Stable PerformanceWe adopt chromium-free passivation environmental protection process, the zinc coating has no release of toxic and harmful substances, and is compliant with EU RoHS directives and domestic environmental protection requirements. The coating adhesion has passed the 180° bending test without peeling off, and the performance is stable under complex working conditions such as high and low temperature and vibration, eliminating the risk of structural failure.

2 Typical Successful Projects

Project 1: Municipal Road Guardrail Project in Coastal CityWe supplied Q235 Shunchen Galvanized Flat Bar (specifications: 8mm×80mm, 6mm×50mm) with a total volume of 120 tons for the 8.5km main road guardrail upgrade project in a coastal city. Aiming at the coastal salt spray corrosion environment, we optimized the galvanizing process. The product has shown no rust or deformation after 5 years of service, fully meeting the 15-year service life requirement of the project. It has greatly reduced the municipal maintenance cost and won high recognition from the project party.

Project 2: Earthing Grid Project of 220kV Outdoor SubstationWe supplied 80 tons of Q355 Shunchen Galvanized Flat Bar (specification: 10mm×100mm) for a substation in a rainy area, which forms a complete system with galvanized angle steel earthing electrodes. The product has excellent electrical conductivity and corrosion resistance. After 3 years of operation in a rainy environment, the earthing resistance value is stable and up to standard, with no rust phenomenon, ensuring the safe operation of the substation.
