1.2mm Thick Galvanized Steel Sheet Hot Dipped Steel Plate Iron Steel Galvanized Metal Sheet

1.2mm Thick Galvanized Steel Sheet Description

The key information about 1.2mm thick hot-dip galvanized steel plates is summarized as follows:

I. Core Specifications and Performance

1. Substrate and coating

    The base material is mostly Q235B cold-rolled steel plate (yield strength ≥235MPa, tensile strength 370-500 mpa).

    The total weight of the hot-dip galvanized coating on both sides is 275g/m² (Z275 standard), forming a zinc-iron alloy layer with a thickness of approximately 19.26μm. There is no red rust for 1000 hours in the salt spray test, and it remains intact after the wet heat cycle test.

2. Processing characteristics

    It supports processes such as bending, stamping and welding. The closed die design (such as the YXB75-230-690 model) can enhance the seismic performance, with the seismic displacement Angle controlled within 1/200.

Ii. Typical Application Scenarios

1. Field of architecture

    Roof and walls: A certain logistics center in Shanghai uses 1.2mm thick galvanized profiled steel sheets for the roof, with a wind resistance capacity of 5.0kPa (typhoon level 12), reducing maintenance costs by 30%.

    Floor deck: Such as YXB60-253-760(B) type closed profiled steel sheet, with an effective coverage width of 760mm, a section moment of inertia of 48.6cm⁴/m, and a flexural strength of 18.5kN·m, it is a permanent formwork suitable for pouring concrete.

2. Transportation and Infrastructure

    Highway guardrails, railway sound barriers, power transmission towers, etc., taking advantage of their salt spray corrosion resistance, can have a service life of over 30 years in coastal or industrial areas.

3. Industrial equipment

    The shell of evaporative cooling equipment, mine transmission pipelines, etc., the self-healing property of the zinc coating can resist the corrosion of acid and alkali media, thus extending the service life of the equipment.
