F436 Structural Steel Washers; Zinc plated; Construction, Bridges, machinery and automobile manufacturing
Standard:F436
Description:
The F436 washer, also known as a structural steel washer, is a hardened steel washer commonly used in structural applications. It is designed to meet the requirements of ASTM F436, which is a standard specification for hardened steel washers.
The F436 washer is available in various sizes, ranging from 1/4" to 4" in diameter. The size is specified in inches and corresponds to the nominal diameter of the fastener it is designed to be used with.
In terms of surface finishes, F436 washers are commonly available with two main options: zinc plated and HDG (Hot-Dip Galvanized).
1.Zinc Plated: Zinc plating involves applying a thin layer of zinc coating to the surface of the washer. This provides moderate corrosion resistance and helps protect the washer from rust and other forms of corrosion. Zinc-plated F436 washers are often used in applications where the washer is not exposed to harsh environments or where additional corrosion protection measures are applied.
2.HDG (Hot-Dip Galvanized): HDG involves immersing the washer in a bath of molten zinc, forming a thick, protective coating on the surface. HDG provides excellent corrosion resistance, making it suitable for applications where the washer will be exposed to harsh or corrosive environments. HDG F436 washers are commonly used in outdoor applications, such as construction, infrastructure, and marine projects.
The choice between zinc plated and HDG depends on the specific requirements of your application, including the environmental conditions and the level of corrosion resistance needed.
