Product name: Weathering board.

Level: Q235NH, Q355NH

Standard: GB/T4171-2008

Technology: Hot rolling, controlled rolling or normalizing, etc

Processing methods: bending, welding, uncoiling, cutting, punching, polishing, or according to customer requirements

Usage: High performance weather resistant and fire-resistant steel can reduce the maintenance cost of steel structures, providing a new solution for the fire and corrosion prevention of exposed unprotected steel structures, such as high-voltage electric towers. The production and installation process of fire-resistant and weather resistant steel is basically the same as that of conventional steel, and the design method is also the same as that of ordinary steel structures, but more experimental verification is required. High strength weather resistant steel has been widely applied in bridge engineering, and research on design theories and methods is needed. Refractory and weather resistant steel can also be used for floor slabs

Value added technology: galvanizing, painting, anti-corrosion coating,
